However, there are many questions from the new users of iPad related to connectivity and several other aspects. Connecting to Wi-Fi is the crucial need for every iPad users as, without the internet, nothing can be done nowadays.

1. Way to connect iPad to WiFi (Routers)

Like any other devices, iPad can also be connected to Wireless networks by selecting the available systems and then entering the network encryption key, but there are some additional settings too.

Requirements for connecting to Router WiFi

A Router with the internet connection.
SSID (Service Set Identifier).
Encryption key
Type of security key whether it is WPA or WEP and WEP can be used as an alternative of the other if the device is unable to accept the WPA mode.

How to obtain this information?

The information of the encryption key, as well as SSID, is usually displayed on the back of the router.
Most routers are configured to WPA by default which can also be changed to WEP if your iPad can’t accept the WPA mode.
An in-home agent can be accessed on a PC which is already connected to the router either with wired or else with wireless connectivity procedure.
Go to the Networking tab readily available in it and select “Retrieve SSID and WEP/WPA key.
Login to the router with the required details asked from the back of the router, and you will be connected to the WiFi.
Later the password which is set in the computer that may either be default one or the changed can be fed to the iPad to connect with the WiFi.

These instructions can vary with some companies of routers, but most of them follow this standard procedure to get connected to a Wi-Fi connection.

Steps to be followed to connect an iPad to the Wi-Fi Router

If you are using a new router with the default passwords, then above mentioned instructions must be followed to get access to the internet in iPad or else devices with WEP accepting devices can’t be connected.

No one believes in sitting at one single place to connect with the world. Which is why most homes have WiFi network installed these days. But the same WiFi connectivity can become a frustrating struggle if you find yourself struggling with bad reception, slow speeds and/or any other problem.

To boost your home WiFi, this article presents 10 great ways.

1. Get a new WiFi adapter to attach to your old laptop

You can invest in a WiFi adapter and use it to boost the connectivity when using an old laptop. Such an adapter will come with 802.11ac technology. You can plug the adapter in one of the USB ports available in your laptop.

Anayse productivity with wifi attendance ad banner

They might look bulky, but definitely increase the speed of wireless network you receive from your router. However, it is important that you choose a high-quality adapter with good AC capabilities.

For instance, AC1200 is considered the minimum required level. Anything below this won’t provide the speed you are looking for.

2. Invest in a router of 802.11ac category

An 802.11ac is also known as an AC category router in the market. If you have a router which belongs to N or G category, you definitely need an upgrade.

These categories are considered cheap as they don’t have the capacity to transfer the high-quality speed of the network to the connected devices. Your network gets faster and delivers maximum connectivity when you have an AC category router.

Of course, you will feel confused when purchasing a new router. Which is why you need to understand the basics in advance before making a decision.

Most of your home devices such as laptops, tablets, smartphones, and others consist of AC wireless technology. So, you can feel free to pick a router in the category of 802.11ac.

All the future devices in the upcoming years will include the AC wireless tech only. So, switching your router would be a wise move.

When you get a new router, you get firmware updates that protect against various security issues. These security features are not upgraded usually in N or G types of routers.

The strength of the performance in 802.11ac comes in the form of its range and speed. You can get dual-band or even a tri-band router to get better device connection management. So, all devices get the best speeds.

3. Consider a system of WiFi mesh

If your WiFi performance is not reaching every corner of your big home, you can think about several solutions. First of all, you can try to include different access points in your home to cover area corner with wireless network.

You can use a WiFi extender to enhance the signal in certain areas. Find places where you can use Ethernet cables to create wired connections.

Beyond all that, very big homes can also consider using the system of WiFi mesh. This will be a one-step solution for all the WiFi performance issues you find in some areas of your home.

Mesh systems are designed for easy installation and provide controllability using a specific mobile application. They surely use some speed, but provide better performance by enhancing the range and the quality of connections. This way, you can sit anywhere in your big house and still get the best possible speeds.

4. Keep your router in an open area

No one feels thrilled about the design of a router. Which is why people usually put in a cupboard or hidden behind the curtains. But the placement of the router also decides the signal performance you receive.

So, a router in your TV cabinet might not send proper signals in every part of your home. The best location for a router is out in an open area. The area should be a flat surface such as a table.

Moreover, you can try to get it installed on a wall. There are router mounting brackets available in the market, which you can use to fulfill this purpose. If possible, try to place the two antennas perpendicular to each other.

5. Select a central area for router placement

You should also carefully choose a central area in your home to place the router. This will ensure complete coverage of the whole house. The signal comes out from the antennas of a router.

Then, it extends in all directions. So, if you place your router in one corner, you will be wasting one aspect of signal that comes out of it.

Mostly, people feel restricted to place a router in a corner due to the short-length of cables. But the problem is resolvable with Ethernet cables. You can ensure the central location of Wi-Fi with Ethernet cables.

You will need professionals’ help to have these cables in your behind the walls or above the ceiling. If not, you can also use cable clips to attach these cables to the walls.

6. Find a suitable wireless channel

If other families also use WiFi in your neighborhood, their access points and routers can interfere with yours. This can degrade the quality of signals.

The good news is that a wireless network can easily operate via different channels. You simply need to pick a channel that has the least possible interference.

Generally, your router knows the right channel and pick automatically. But you should take a look to ensure if it is causing the network issues. There are tools that help you analyze your Wi-Fi, which you can find online.

7. Secure your wireless network from hackers

WiFi security holds great importance to keep your wireless network performance top-notch. If hackers get a chance, they use your network and reduce the quality of internet speed you receive.

The most important part of securing your WiFi network is keeping the firmware updated. Your router comes with firmware security features. It is important that you keep it updated with the new features provided by the manufacturers.

To create WiFi passwords, you should utilize WPA2 encryption, as it is the latest technology. At the same time, you can’t keep using the default password and username. It is too obvious to guess and opens your network for hackers. You should customize the login details and keep it secure.

Whenever you are not using the connection, use the physical switch off button on the router to turn it off. Switch it on with your fingers to start the WPS for configuration. Also, if there are remote management features available in your router, disable them whenever not required.

8. Use simple tricks to increase WiFi range

The range of a wireless network is the area it covers when sending the signal. You can increase its capacity by some simple tricks. For this, you will need an old can of beer.

Carefully cut out the top part of the can to make it look like a glass. Then, you need to make a hole in the center of the bottom of the can. Make sure this hole is sharp and wide enough to go inside your router’s antenna.

Now, you need to cut the beer can vertically once, and cut from the circumference of the bottom, leaving a little portion attached to the bottom part.

Use your hands to open the can to shape it like a curved antenna. Then, put it on the antennas by crossing it through the bottom hole. This will give a boost to your wireless network range.

9. Invest in a WiFi extender

If you want some serious improvement in the wireless range department, an extender would be a wise move. The Wi-Fi extenders are also known as boosters and repeaters.

They catch the signal coming from the main router and redistribute with higher quality. The amplification of the signal improves the range of a wireless network in your home.

You can easily install an extender in the area where the signal is weak. The process of installation doesn’t take more than several minutes.

Modern-age extenders allow you to control them using online or mobile phone applications. You can also adjust the Wi-Fi settings with them according to your preference. This increases the performance and experience of using WiFi routers at home.

10. Take your router to new access points

Good quality routers allow you to quickly and easily change their location to new access points. The process of hardware disabling takes seconds, so you can decide the location with respect to different access points.

You can do this manually and allow all kinds of equipment, old or new, to receive the best connection performance.

Along with all the mentioned ways, you can also think about getting stronger antennas for your router. Also, try to manage some applications on your device that take a lot of bandwidth.

And if you find yourself struggling with a low-quality wireless network speed or range, reboot the router. This process will start the router again and might bring back the regular strength in the wireless network.

Hopefully, these tips will help you!

WiFi and Bluetooth are two modes of wireless communication. Both modes utilize radio signals to establish connection. But there is a core difference between these two with respect to the purpose they serve.

Bluetooth allows connection in a short range between devices. This helps in sharing data between the connected devices.

On the contrary, WiFi enables access to the internet.

Bluetooth is limited to the devices connected in a short range. But there is a higher connection possibility for WiFi users.

The bandwidth also changes between the two modes. WiFi offers higher speed due to high bandwidth, while Bluetooth connection works on low bandwidth.

Bluetooth

1. What is Bluetooth?

Bluetooth is a universal mode of wireless connection that works in a short range. This wireless connection is used for data communications.

IBM, Nokia, Toshiba, and Ericsson are the companies that invented Bluetooth. However, it was Intel that created SIG or Special Internet Group to promote the concept of Bluetooth.

They also developed Wireless Personal Area Network or WPAN. With that, Bluetooth became the very first technology for short-distance wireless network for data application and communication.

The rate of data is pretty low with respect to WiFi. But it offers an inexpensive way of creating a small but effective wireless network.

Using Bluetooth SIG, the process of cable replacement takes place. Ad-hoc network becomes possible. Plus, connected devices create APs or Integrated Access Points. These access points allow all users to utilize wireless voice and data.

2. What is the architecture of Bluetooth?

The topology of Bluetooth is called the scattered kind of ad-hoc topology. This topology defines the collection of connected devices in an ad-hoc way. This collection is called Piconet.

There are total 4 states of Bluetooth connection:

M or Master- This state can contain 7 to 200 collections of slaves in the active
S or Slave- The slaves are the names given to terminals. These terminals can become a part of one or more piconet at once.
SB or Stand by- These stay in line to join an existing piconet. During the waiting period, SB’s MAC address stay retained in them.
P or Parked/hold- P are the ones waiting to get attached to the existing piconet. But these ones release their MAC address.

3. How is a physical connection developed to use Bluetooth?

To create a physical connection, a modem with FHSS type is used. FHSS or Frequency Hopping Spread Spectrum modem is leveraged along with 0 dBm of antenna power. Alternatively, 20 dBm can be used for the operation as well.

The hopping rate of Bluetooth should be 1600 hops/second. Bluetooth can attain a specific hopping format for every piconet, which is known as its frequency.

4. How to manage a Bluetooth connection?

The connection takes two major processes for an establishment. These processes are called Inquiry connection and Page connection.

Every active device is assigned to 3-bit in AMA (also known as Active Member Address). Every parked device gets allocated to 8-bit in PMA (also known as Parked Member Address). There is no address required for standby devices.

Sniff- In this state, slaves listen minimized rate of the piconet.
Hold- Slave restricts all the ACL transmission and allows SCO packet exchange.
Park- Slave allows the release of AMA it has.
Page- AMA becomes the master after getting assigned.
Connected- The process of listening, transmitting and receiving is involved in this state.
Standby- The listening process happens periodically.
Inquiry- A search is conducted to locate other devices in the network area.

5. What about the security aspect of Bluetooth?

With Bluetooth, you can expect information confidentiality and usage security as well. The utilization of a random number, device’s MAC address ensures its security.

The two-step approach, Authentication, and Encryption, further enhances the security. However, there are three ways of Bluetooth operations, which are non-secure, link level and service level.

WiFi

1. What is WiFi?

Wi-Fi is also called Wireless Fidelity. This technical name is IEEE 802.11 suite. This standard was the initial WLANs standard. These same standards create an interface that ensures transmission and receiving process between multiple wireless clients and access point.

With 802.11 standards, inventors wanted to increase the range of wireless connectivity. Making portable, permanent and mobile connections, these standards lead to the development of much-needed PHY and MAC layer.

Features of IEEE 802.11 standard include:

It enables a time-bounded, asynchronous delivery facility.
It provides support to continuous service in the whole area that comes within the distribution system.

2. What is the architecture of WiFi?

The topologies or operation models have two types:

Infrastructure topology: This mode generally contains at least one AP or access point. The AP stays linked to a wired infrastructure of the network along with multiple wireless stations. AP has the control over encryption and creates the route for wireless traffic towards the internet network.
Ad-hoc topology: In this mode, two wireless stations connect with each other directly without any access point. There is also no need for a wired network in this mode. This topology is also called IBSS or Independent Basic Service Set. A wireless network between two laptops is an Ad-Hoc mode.

3. What about WiFi’s security?

There are provisions provided for privacy and authentication path. The authentication process can be done in two ways:

Open system- This is a default scheme of authentication. An algorithm ID for authentication is sent by a request frame. The results of this request are judged with respect to the response time.
Shared key- This authentication mode is more secure. In this, a request frame usually carries a 40-bit encrypted code, which is used for frame ID authentication. This code stays secret between the IP and the request frame. Two stations complete the process of sending, encrypting and responding with the secret code. This completes the authentication process.

Bluetooth vs WiFi

1. Bandwidth

Bluetooth bandwidth stays low, while WiFi works with high bandwidth. This is due to the range of network and the limitations associated with the connected devices.

2. Required hardware

The devices need to have Bluetooth adapter in order to connect in a Bluetooth network with each other. The connection to Wi-Fi requires the availability of a wireless adapter in every device along with the availability of one wireless router.

In terms of required hardware, both types require their own adapter availability. However, WiFi needs one wireless router as well.

3. Usability

When it comes to usability, Bluetooth network seems pretty simple. The connection is small, which allows users to easily switch from one device to another for a new connection.

The process of using WiFi is a bit complicated with respect to Bluetooth. First of all, it requires the correct installation and configuration of router. The software configuration also takes complex steps. Only then, the complete setup establishes WiFi network connectivity.

4. Range

In terms of connection range, Bluetooth provides a small area of network around 10 meters. This is nothing when you see the connection range of WiFi. A WiFi network can give you 100 meters of connection range.

5. Security

When compared in terms of security, WiFi seems better than Bluetooth. WiFi offers better security features. Which is why Bluetooth seems less secure as compared to WiFi. However, there are security issues regarding the use of WiFi as well.

6. Use of energy

The energy consumption is pretty low in Bluetooth, which makes it easier to install in small devices as well. The WiFi network takes higher energy, as there is a router involved along with multiple network stations.

7. Range of frequency

The frequency can range 2.400-2.483 GHz in a Bluetooth network. This range goes up to 2.4-5 GHz in WiFi. This frequency range is the reason why Wi-Fi enables better and more complex connections.

8. User flexibility

Bluetooth allows a certain number of devices to connect together in a short range. So, the user flexibility is pretty low in this type of network as compared to WiFi.

With WiFi, many users can get access to the network at once.

9. Modulation techniques

The modulation technique for Bluetooth is GFSK or Gaussian Frequency Shift Keying.

The modulation technique for WiFi network is OFDM or Orthogonal Frequency Division Multiplexing. It can also use another technique called QAM or Quadrature Amplitude Modulation.

Conclusion

Both WiFi and Bluetooth technologies have enabled users in terms of wireless communication. Multiple devices can connect with each other and share data. The purpose of both connection types is different, but they both have their own advantages.

While Bluetooth works fairly to connect devices in a short range, you need WiFi to get large connectivity to the internet.

With this knowledge, you can now utilize both kinds of wireless communications as per your need. You know the advantages, so choose a type of network that aligns with what you are trying to accomplish.

For instance, large connectivity for multiple users asks for WiFi. But you can connect two devices using Bluetooth for data transfer in a short range.

Internet has come a long way since the last few years, changing the digital landscape and transforming it in the process.

Of course, the argument as to whether the digital companies owe their very survival to broadband or to WiFi is an open question for not many are aware of the key differences between both.

If you thought that both are one and the same, you could not be more wrong, here’s why.

Internet was available to all through dial-ups and modems, but thanks to various advances, customers can now access sites at a higher speed, upload or download large packets of data, thanks to broadband.

But with the advent of broadband, ADSL broadband, cable broadband, but a little later on, companies have started offering WiFi which can match most of what broadband has to offer.

In case, you are still confused as to the key differences between the two, then you need to read on.

WiFi and Broadband

Before you can spot out the differences between both, you should know that WiFi is a wireless LAN technology that enables you to access the net.

The downside is that it operates over open spectrum at low ranges which means that you need to stay either in the same room or nearby to use the WiFi.

A few companies have even started boosting their WiFi signal so that customers can access the same over wider area. Broadband is also wireless, where you would be able to access your broadband connection through your phone or with broadband cable.

The other down-side to WiFi is that it is often subject to interference which is not the case with broadband.

Broadband enables you to connect online at high speeds; it comes with various options from ADSL, to cable that you can access at any time and also comes with a connection that is never switched off.

It should be pointed out that while the terminology of broadband is not all that surprising, not many are aware of the fact that broad band’s opposite term, narrow band has been used for dial-ups and modems alike.

There are various advantages to both, which you may want to take a closer look at.

But before that, you may want to know that WiFi essentially uses radio technology and is therefore subject to interference in case of severe solar storm, for example.

With WiFi, connection is often established with the help of a router, and with the help of a wireless adapter to create hot spots.

What’s more, with WiFi is, you should be able to connect more than one device to the network, and once the WiFi is on, it should start emitting frequencies between 2.4 GHz and 5 GHz.

What has helped to make WiFi popular is the fact that it is compatible with almost all operating systems and just about anything else.

Just remember that if you are connecting online using WiFi, then you would be sharing the connection with many, and the speed may be limited depending on the strength of the signal.

Advantages and differences between Broadband and WiFi

When it comes to broadband and WiFi, it can get a tad confusing and that’s an understatement with more acronyms clouding the digital space than you can shake a stick at.

The fact is that even your local smart phone enables you to connect online with at least three methods, and all you need is to enable your laptop to one of these and you should be able to connect online.

WiFi is where telecom companies can provide you with WiFi access to your system by providing you with a modem and a router.

Once the device is switched on, you should be able to connect online as long as you stay in the same room or within 75 meters of the device,whereas with Broadband, you can count on a secure connection and stay connected for as long as you like.

Some of the pros and cons of WiFi and Broadband are listed here

Pros

It offers you with high speed internet and the ability to connect with the same right away
It enables you to connect multiple devices to the same WiFi connection
It is reasonably priced but that depends more on your provider

Cons

One of the drawbacks is that a WiFi signal cannot really be considered secure, for “packet sniffers” can sometimes sniff out the signal and read the signal between a computer and a device.
WiFi is based on radio signals, and can also be subject to interference especially during severe solar storms.

Broadband

Pros

It also offers you high speed internet and you need not switch it off anytime and it is always on. You should be able to transfer large amounts of data with the help of broadband and even access similar amounts of data.
It is a secure connection
It is a wired connection and enables you to enjoy high speed internet all the time
It is reasonably priced

Cons

The broadband connection is secure; in the sense that it does not permit you to share the connection with others, unless they log into the same system with your credentials.It should also be pointed out that you can connect a certain amount of devices with your broadband, and enjoy the perks of being connected via a broadband line.
It is a wired connection meaning that your system would have to be physically connected with the broadband cable.

As you can see, here are some of the pros and cons of a broadband connection and a WiFi and the cost for the same, can vary from one provider to another.

While you can use the hot spot and surf with your WiFi, the fact remains that WiFi lines are not that secure whereas broadband is, all the way.

Smartphones

Since the advent of smart phones and 4G, you can now connect online using the phone’s WiFi signal or use its broadband connection.

While there is not much difference between the WiFi Signal on your phone or its broadband connection, as both are dependent on the data package you subscribed with your operator, the fact remains that both are unique and use various methods to help you connect online.

And while it may not be possible for you to connect several devices with a secured and wired broadband connection, you should still be able to do so with your smart phone.

As regards the method, all you would have to do is to head over to the settings on the phone and check for internet and connections.

Now, click on the same and you should soon be able to access various options, from WiFi to broadband which you can then access with the help of mobile hot spot.

But in case the terms wireless and broadband are still a tad mystifying, here’s the breakdown – a wireless connection is one that utilizes radio frequencies to help you stay connected.

On the other hand, a broadband connection is one that offers you high speed data connectivity, without using radio frequencies and one that offers you both wired and wireless, which is what makes it all the more confusing as it is getting harder to tell the two apart, especially for the lay person.

Wireless routers

With more telecom operators getting into the play, it seems that more companies are now offering bundled routers and modems with their broadband connection.

Additionally they are also offering wireless routers which mean that you do not have to stay physically connected to the router in order to access internet.

Thanks to this, you can count on high speed broadband connection and move about, in close proximity as you access the same.

Conclusion:

Of the two, WiFi certainly sounds much better for the simple reason that you can connect multiple devices to the same connection.

This is not possible with a secured broadband connection but on the other hand, it should be pointed out that WiFi’s are not secure and in more ways than one.

What’s more, with a broad band connection, you should be able to access vast amounts of data, send over similar amounts with ease than you could do with your WiFi connection.

This is why broadband connection remains a hot favorite with many.

With internet getting faster, it was expected that most of the data providers would be hiking their charges, which is why it makes more sense to try and see if you can get an internet connection for free .

The average WiFi is costing the layman approximately $50 per month, which works out to a massive $600 per year.

With more innovations and updates in the digital spectrum, you can expect higher speeds, faster downloads,and higher fees.

Given all this, wouldn’t it be better to surf the net for free? Granted, it may sound like a dream but here’s how you go about the same.

Getting WiFi without internet

The fact is that free internet is not illegal, not in any sense of the word but the problem is that most do not know that you can indeed get free internet and end up paying a monthly fee for the same.

In fact, the government offers several programs for those who reside below the poverty line, which includes free internet, but other than that, there are a few options across the board that you may want to check out.

1. Freedom POP

Freedom POP is a company that specializes in offering free internet services, and of course, this includes the usual ads that run in the background.

But the fact is that this company provides you with free internet, and even sends you a free hotspot device.

You would be required to pay a small security deposit which is returnable at the end of the year, assuming you return the device around then.

What makes Freedom POP attractive is that all you need to do is to sign up on the website and they’ll send you the manual and charger, and you should be able to surf the net for free.

Keep in mind that initially, you would end up getting about 10GB of data for the first month but after that, this should go down to 500MB per month which is not much, but enough for you to surf online and check your emails.

2. WiFi free spot

This Company provides you with a list of all the local shops and businesses in your area that offer free WiFi.

All you have to do is to check online, for all the free listings and take advantage of the same.

The process is quite simple. All you have to do is to head over to your state and county, and the website should provide you with the list of all local businesses that offer free wifi without internet.

And if you reside nearby, then you can use their connection for free. And if you want to check all the local free WiFi spots, as you travel, you can download and install the WiFi Map, on your phone.

3. Check with your internet service provider

It may come as a surprise but many ISP providers offer dirt cheap data packages that you can avail and some even offer free internet.

Usually, your ISP may try up selling you their packages so that you end up with more data than you would ever need. It is important that you query them regarding the various data packages they have on offer and go in for the one that sounds like a good fit.

See if they offer bundled services for there are good chances that you may get internet for free. Usually, they offer free internet with bundled services for free for a year, after which you would be required to subscribe for the same.

4. 10 free hours of internet for a month

It may not sound like much but if you are not a heavy internet user, then this would be perfect for you.

Both Netzero and Juno are two ISP providers who provide ten hours of free internet a month. It is meant for those who are looking for ways to keep in touch with their loved ones via email.

This service is predominantly dial-up and you can use the same to surf online for free, ten hours a month.

But do note, if you are looking to use the same for watching videos or movies online, then it would get used up very quickly.

5. Ask a neighbor

It all depends on how good a relationship you have with your neighbor; assuming that it is good, you can request them to share their connection or you can make an offer where you get to pay for their WiFi connection every alternate month, which essentially means that you get six months of free wifi without internet.

If you are planning to head down this route, it may be a good idea to draw up an agreement so that your interests are protected.

6. Municipal wireless network

The municipal wireless network is fast catching on. The local municipality offers free internet but with it, you would get more than a few restrictions.

Essentially, it is meant for local businesses to stay connected and as a resident, you can piggyback on the WiFi connection.

But it should also be pointed out that not all the municipalities have the same but only a select few but you can always check online as to whether your municipality offers you free WiFi.

Some of the restrictions involve you accessing the net for just a few hours, not more than that and you may have to access it in a café or in a park, and not inside your home.

7. Bookmark cheap internet

Sounds too good to be true but in reality, there is a dedicated website that provides you with up to date information on cheap internet offers – which ISP is offering what and whom to approach for the cheapest data package.

Given that the usual cost is around $50, with the help of this website, you should be able to find something that is affordable and in your price range.

You will have to click on “plans by state” for a list of current offers in your state and select one that you think is a good fit.

If you belong to the low-income group, then you would definitely want to bookmark this website as it has some fantastic offers, including the fact that you may be eligible for some of them on account of your current fiscal status.

8. Mobile hotspot

Of course, you can always use your mobile phone as a hotspot; the fact is that mobile carriers offer wifi without internet and often charge you as little as possible for using the bandwidth on their plans.

They generally upsell the same to you and bundled with the phone, you get free wifi without internet.

All you have to do is to head over to settings, click on the internet and the drop-down list containing more than a few options should open up.

Now, all that is left for you to do is to choose the ‘mobile hotspot’ and enter the keyword given in your system or laptop and you would be set to go.

Keep in mind that you are only allowed to use a certain amount of data each day, and additional charges may apply should you exceed the same.

9. See if your school offers free internet

A good idea would be to check and see if your school offers free internet; some do specially to enable students from low-income groups to stay connected so as to enable them to research their papers, review their homework and streamline their performance as a result.

If you are planning to apply for the same, then you would have to apply to meet your district state commissioner and make your case, as to how you and your kids come from a low-income group.

There is no clarity on how families get picked for the same but one criterion is thought to be the income status of that particular family.

10. Cheap internet services

For example, AT&T offers you low-cost internet services for the low-income group; there is no bar and anyone can apply for the same and it costs only as low as $5 and nothing can beat this price tag when you compare it with the $50 one.

The only downside is that the speed is rather slow and can come down even to 3Mbps.

Or you can go ahead with internet essentials by Comcast which costs only $9.95 per month, and comes with a decent speed and certainly trumps AT&T.

These are some of the ways that you can get free WiFi without subscribing to any internet service provider.

It all comes down to what you plan to use the internet for and then, check and see one of the options listed above, and decide which one you want to go ahead with.

Just remember, that there is no such thing as a ‘free lunch’, and you would have to subscribe in order to get premium services.

If you think, WiFi is just a bunch of radio waves exclusively meant for providing internet access, you are wrong.

If they have the power to retrieve information from another corner of the world, imagine what they could achieve in the residing premises.

If wireless media transfer was the dawn of the space age technology, IoT was the sun that brightened our day. All what made all this possible? WiFi indeed!

So would you still consider it a pompous conjecture that WiFi has more tricks up it’s sleeve?

If so, we have something that might clear the air!

A study co-authored by professor Yingying (Jennifer) Chen from the Rutger’s university claims to have prototyped a detection system which uses WiFi to sense bombs and weapons.

How does it work?

Rutger’s university researchers recently claimed the use of WiFi in detection of bombs and weapons. The existing WiFi networks instead of being used for browsing internet can be used to detect bombs, chemical explosives and guns in a large area.

People passing through the receptors will be scanned and any suspicious objects detected will be shown on the system in the form of an alert.

So what exactly is the knack of this technology?

We are aware that weapons and bombs are mainly made of materials like metal and liquid. The meddling of WiFi specifically with these materials is what does the trick.

The baggage used to carry these materials are usually made of materials like fibre, cloth etc which the WiFi can easily penetrate.

WiFi signals pierce into sealed packages and items scanning the vitals of the metal objects. In addition it can also retrieve the volume of liquid.

Researchers have tested the method using 15 kinds of objects and 6 types of bags which has led them to accomplish a result with 99% accuracy in distinguishing dangerous materials from non dangerous. Accuracy with metals was found to be 98 percent and that of liquids was 95.

So far the method has assured 95% accuracy. But the accuracy rates have been found to drop to upto 90% when the objects inside the bags are wrapped. But the drop can be compensated for by doing some tweaks to the existing implement.

Required infrastructure and mode of working

The system typically requires a WiFi network integrated with transmitting and receiving antennas. The signal enters the interiors of the sealed object, scans the entire containment and bounces of giving an exact picture of what comprises the bag or package.

Advantage

Usual checking procedures follow hardened methods of going through people’s baggage and needs them to concede to physical detector scans. The novel improvement in the detection system will not invade public privacy in any way.

The checking procedure is less demanding and evokes absolutely no panic. We can call it a low-key way of checking. No need to physically open bags and check them. No extra man power required for the purpose of ensuring safety

As compared to individual screening, WiFi can scan more packages than usual detecting systems and that too in a smaller window of time.

We know for a fact that in places with tight security a special expensive infrastructure is required to be erected to ensure protection. It is not always possible to implement it in public places. WiFi routers are easy to set up and occupy a significantly lesser space.

Now that we know the technology uses off-the-shelf WiFi devices to function, the system would naturally lead to Lowering the cost of the entire cost set-up. The researchers have estimated the technology will cost, not more than a $100.

Applications

This is definitely a cost effective solution to the entryway check up procedures which otherwise uses x-ray and other expensive implements.

When the crowd is huge, this technology can be attached to motorized cars and scan the area as it moves.

Conclusions

The researchers are sure that the WiFi based weapon detection technology will replace much manpower from areas like airports, stadiums, malls and other public places.

It is not one hundred percent sure as of yet if the technology could be a promising substitute for the intensive radio wave powered detection instruments. But it will definitely enhance the security at places which demand high protection and alert.
