A public WiFi hotspot is a network that everyone from the general public has access to. Users can use it to connect to other networks or the Internet.

A public network does not necessarily have restrictions and therefore one of the significant factors opposing its use is the security risks involved with it.

Public WiFi is extremely vulnerable to intercepts by hackers. Only if it is used with a virtual private network is its security guaranteed.

WiFi hotspots are also secure if they have been upgraded to the WiFi Protected Access (WPA3) standard. This upgrade requires the buying and installation of new routers.

While these concerns are of immense importance, they cannot contradict the truth that public WiFi hotspots help to speed up the cause of creating a digitally advanced country – Digital India. There are several benefits that people can reap from the rise in public Wi-Fi hotspots.

Reduced Network Congestion

To begin with, people struggle with the challenges of call drops. They experience 2G internet speeds even after having 3G and 4G connections.

Public WiFi hotspots are capable of addressing this issue. When WiFi infrastructure is shared, it offloads the traffic otherwise loaded on WiFi networks.

This reduces network congestion on mobile networks, especially in areas of high footfall. As the spectrum is freed from other loads of WiFi connectivity, the quality of calls starts to improve and congestion issues reduce.

In developed countries like the UK, France, and the US, approximately 30% of data usage is passed on to public Wi-Fi networks, as compared to a mere 16% in India.

Reduces Digital Divide

According to the Analysis Mason report, commissioned by Google, a rise in public WiFi hotspots in India will help 600 million people to get access to WiFi networks.

For successful WiFi infrastructure, more than 3 million access points need to be set up in the entire country across tier-3 cities and villages.

With faster internet speeds, passengers will be able to utilize their time better, which in turn is beneficial for the venue owners (particularly railway stations and airports).

More Economical

The deployment and utilization of public Wi-Fi hotspots can be cheaper in comparison to 3G and 4G networks. This is true in areas where fiber access to backhaul already exists.

Empowerment

Public Wi-Fi hotspots are a great opportunity for government institutions. This is because they can transform the area into a smart city.

Governments can improve their efficiency and empower the citizens with better services. Access to e-governance and electronic delivery of services such as Aadhar also gets boosted with the deployment of public Wi-Fi hotspots.

Tourism is also greatly impacted as a result of public WiFi access. When traveling, tourists like to stay in touch with their family and friends.

They like to access the internet for suggestions on sight-seeing, maps, and also sharing holiday pictures on their social networks. Tourists are more attracted to visit a destination that offers free internet services on-the-go.

Is the rise in public WiFi hotspots a boon for the country?

These advantages as solutions to congestion issues do not nullify the security concerns surrounding public WiFi. A report published by Symantec last year (2017) states that 96 percent of Indians are prone to the risks of data theft and other cyber crimes as they use public WiFi for accessing bank accounts and sending important media.

Cybercriminals aggressively target unsecured WiFi networks. The study also concluded that around one-third of the users in India accessed public WiFi for the purpose of watching explicit content.

Another interesting finding of the study stated that half of the Indian users connected to WiFi networks without the consent of the network’s owner.

These factors pose a huge risk to users. Nevertheless, many countries across the globe are installing public WiFi networks with the focus on securing them even more.

The number of WiFi users across the globe has crossed 9 billion and their protection over WiFi has become extremely crucial. This can only happen when the wireless security protocol is upgraded even further.

But keeping users away from the benefits of public WiFi hotspots in the name of poor security is not a good idea.

Concentration of population in cities has been increasing since industrialisation. Millions of people immigrate to IT and Manufacturing hubs of the world today.

According to McKinsey, urban population is set to grow by 65 million per year by 2025. Technological advancements like internet of things, artificial intelligence and data analytics show promising potential to solve problems plaguing cities.

What is a Smart City?

A smart city is an urban area which uses data, technology and intelligent machines to manage the public assets and resources efficiently.

The vision of smart city is one where communities and environment coexist sustainably. These cities will be connected by high speed internet and will be free of pollution and traffic.

The concept of smart cities has been gaining momentum throughout the world and some countries have even built smart cities.

For example, South Korea has built the world’s first smart city Songdo near its capital Seoul. Everything from waste management to commute is planned intelligently to make a city that is free of cars and trash cans.

WiFi as the Backbone of Smart City

An essential capability of future smart cities the integration of all systems for efficient usage and sustainable development.

This will allow intelligent decisions like diversion of traffic to other routes, detection of security threats or footfall analytics for upcoming projects.

This requires various systems, public authorities, citizens and businesses to be connected to each other in a single frame work.

All this is only possible with an uninterrupted and real-time connection to internet. This is why WiFi forms the backbone of a smart city.

Being the most convenient and secure way to transfer data today, WiFi shows promising application for smart cities.

Internet of Things (IoT) technology is evolving to work with WiFi and hence this wireless technology is best suited for smart cities. A public WiFi with high bandwidth will help smart cities to:

1. Connect the City

It is estimated that 34 billion devices will be connected through internet in the next three years. In a smart city, devices like surveillance camera, building power grids, traffic lights, water supply checks will all be WiFi enabled for communication.

WiFi will enable all IoT based city services to manage resources more efficiently.

For example, traffic flow and parking systems can be controlled remotely by authorities with real time data. Power consumption and water wastage can also be minimised using connections with smart homes of residents.

IP video backhaul can be used for crime detection and a cloud healthcare repository will enable timely healthcare services in emergency.

2. Bridge the Gap

A free WiFi will bridge the digital divide among residents of smart city. Since information is the most important resource in the knowledge economy of today, this will also bridge the social and economic gaps in population.

Smart cities can aim for equality of income, knowledge and opportunities thanks to public WiFi

3. Provide Amenity

WiFi is a valuable commodity for residents, visitors and businesses. Good connectivity will attract residents as well as companies to set up shop in smart cities. Tourists also benefit with good connectivity, easily available information and digital kiosks.

Student community can thrive easily in such an environment and hence universities will look forward to setting up campus in smart cities. In short, WiFi is an essential fuel for the economic engine of smart cities.

Costs of Implementing WiFi

Budgeting of project and costs to end customer have a real impact on the project and they must be taken care of. In the city of Songdo we mentioned above, high living cost is driving away residents.

The smart city that was built for 300,000 has only 100,000 residents and is reeling under project completion delays.

For most smart city projects, governments are doing majority of the project funding. Others projects like the New York’s LinkNYC are working in public-private partnerships.

The cost of WiFi and smart city amenities can be passed on to residents by charging for premium access or maintenance taxes.

Private players can also monetize through ads, promotions and other business services. Since WiFi is a cheap technology that only uses radio waves for transmission of data, it is a low-cost option that will keep the cost of operation minimal.

Security and Privacy

It is clear that a lot many things will be monitored and recorded in a smart city. This gives rise to concern about privacy and security of data.

Private WiFi technology is safe with the implementation of WPA2 protocol but it is not infallible. The security of public WiFi is somewhat weaker and there are cases of hacking in public networks.

Since all critical city systems will be accessible through public WiFi, security of WiFi cannot be compromised in a smart cities.

Questions regarding privacy of data will also have to be addressed. Who owns the data of a smart home and how much of control do the public authorities have in remote controlling of a building or a home? These are some challenges that remain to be solved.

Conclusion

The smart city industry is expected to be worth $400 billion by 2020. Nations will have to either build these cities from ground up or convert big cities using the existing infrastructure.

Whatever the strategy, WiFi will play a central role in functioning of smart city. It will be the enabler of intelligent systems that talk to each other and build a sustainable environment.

Wifi issues can be quiet disruptive if internet lies at the heart of your routine. You cannot access your email and browsers; movie streaming becomes a challenge; updates on social media take too long making you miss out on a lot, and your phones start to depend on data plans.

The reasons for an interruption in your Wi-Fi connection are plenty – the location of the router, firmware limitations, hardware issues, signal congestion, or just the size and vastness of your house.

Whatever it may be, slower internet speeds are not easy to handle and can really bother you at times, especially if you are trying to complete an important task at hand.

Here is a list of some of the most common Wifi issues along with suggested solutions to fix the same:

1. Router Location & Distance

Internet speeds have drastically increased over the last few years. Despite such a tremendous improvement, some wireless and wired networks tend to get bogged down.

Slowing down the speed of data transfer due to the distance of the router is the most common wifi issue. If the router is too far, the connection will get unreliable.

Suggested Solution – Bring your device close to the router. If the router is lying in another room, go into the room where the router is lying and see if that helps to fix the problem.

In case the problem persists, place your router at a height away from other obstructions and interfering devices. You can also try placing it in a central location of your home.

2. Router Firmware

If your router’s firmware is not updated, you could be missing out on the advantages of certain features. Security issues might also be hampering the performance.

Suggested Solution – Visit the administration page of your router and check for any recommended updates. Review, download and install the same to enjoy additional features and improvements.

The step-by-step guide to upgrading your router’s firmware will be dependent on the make and model of the router. Take a look at the manufacturer’s website for more information and detailed directions.

3. Bandwidth

Another common reason for Internet speed slowdowns is lack of bandwidth. When several members in the house are using the internet on different devices to access data-hungry applications, your otherwise fast internet connection spreads out thinly and is distributed across multiple devices.

Suggested Solution – Try and reduce the load by disconnecting devices that don’t require an internet connection. If the use of YouTube and Netflix is high, connect one of the devices directly to the router with the help of a Cat-5 ethernet cable.

This allows for some of the wireless bandwidth to be free. You must also check the data plan you have because if your internet speed from the backend is not enough to support such high use, you will always experience slowdowns.

Another important thing to check is the security of your internet connection. If you have an open network, chances that someone nearby is leeching off your bandwidth are high. Setup the security for your network and share your password only with a few.

4. Outdated Router

Wireless technology has significantly evolved in the last one decade. Wireless standards have updated, internet speeds are faster, fiber is introduced in most areas, and the number of devices requiring an internet connection is higher.

Now, even your television, printer, smartphone, speakers, refrigerator, security systems, lights, and more are dependent on the internet. An outdated router cannot support all devices simultaneously.

Suggested Solution – If the internet speed is affected due to modem limitations, it is time for you to upgrade. It is recommended that you purchase a new router every two years as advancement in technology requires you to upgrade with the latest technology.

5. No Internet

In certain situations, the router just stops communicating because of technical glitches. There isn’t a specific and distinct reason for the same.

Suggested Solution – Start by unplugging both the router and modem. Disconnect power and wait for around 30 seconds before you power it again.

6. Internet Service Outage

Sometimes the internet connection drops completely, not because of a hardware trouble but because of backend service interferences. There isn’t much to explain and do in such a scenario because it just happens.

Suggested Solution – Visit a coffee shop to use their internet services or use your phone’s hotspot connection. Meanwhile, connect with the team at your Internet Service Provider’s end and inform them about the outage so that they can fix it.

Unfortunately, calling the ISP won’t give you instant internet speed and recovery but they will at least be informed of the affected areas and take relevant actions.

Most professionals today are extremely dependent on WiFi services and internet speeds must be fast. If the fixes mentioned above do not help, contact a technician and take their guidance to fix slow internet connections.

Wifi technology is extremely convenient because it allows us to access the internet wirelessly. Connecting your laptop to Wifi is really simple. Let’s look at the components of a Wifi Setup to understand how to connect to a WiFi in three easy steps.

Modem : A modem is device the converts the analog signal into digital signal. It is short from for modulator-demodulator and is required to convert the data from internet that travels through optical fibers.

Quick Fact – Do you know how internet connections are made possible between your Internet Service Provides (ISP) and servers across the globe? This is not done wireless or through the satellite.

Data is transmitted through optical fibers laid in the oceans. These cables are called Submarine Cables and physically connect all the continents and countries of the world.

Router : A router is a device that is connected to Modem and converts the digital data into radio waves. Radio waves are what makes WiFi possible.

Instead of transmitting data from internet via a cable connected to modem (like in the old days), the data in a WiFi network is carried by radio waves.

Nowadays some ISP provide the modem and router in a single device to make things easier. The router is just connected to the cable that comes from the local Internet Service Provider (ISP) of through the ethernet ports given in the apartments (which are again connected to cables by ISP)

Laptop: Your router is connected to your computing device like laptop, mobile and PC through the radio waves. All modern devices have an in-built WiFi adapter that can send and receive data wirelessly (through radio waves) from your router.

This is the setup of a WiFi network, now lets look at how to connect your Laptop to WiFi in 3 simple steps:

Step 1

Make sure your WiFi network is active, router is on and modem is connected. Also keep WiFi password handy as you will be prompted to enter it in next step.

If it’s your first time starting a WiFi in your home/ office you will have to setup the WiFi network with the secure password.

To setup a WiFi, just switch on and connect your router and modem to the cable / Ethernet port provided by your local ISP.

After that you need to go to your browser in your laptop and type in your IP address. This IP address will depend on the router service you use.

For example Belkin users must type in http://192.168.0.1. and Linksys users have to type in http://192.168.1.1. in their browser. You can find this IP address in the router manual or on Google.

You can then set your routers username and password. Set the SSID (wireless capability) as active and type in the username and password provided by your Internet Service Provider (ISP). Choose WPA as your security. You can take help from your ISP to set this up or if you run into problems.

Step 2

Now that the your WiFi is setup and working switch on your laptop. There will be an internet access icon at the bottom right of your screen. Simple click on it and select the name of WiFi you want to connect to ( or the one you set up in previous step).

If you don’t see the icon, go to settings in your laptop. Select Network & Internet in it and select WiFi. Switch on WiFi and you will see all the WiFi networks available in your vicinity. Select the WiFi you want to connect to.

Step 3

Most WiFi networks will have a password to secure data. You will get a prompt to enter in password once you click on the WiFi you want to connect. Just enter the password given by the WiFi owner (of the one you setup in step 1)

Your laptop is not connected to Internet via router and Ethernet/ Dial – In connection provided by your ISP. Remember that the data is being carried form the router to your laptop by the radio waves with frequencies between 2.4 GHz and 5Ghz.

You are now free to move about anywhere within the WiFi range. Usually the range of WiFi router is 50 – 70 meters.

A Word about Public WiFi

Free WiFi are available in every cafe, restaurant and airport today. These are public WiFi available to everyone in the premise.

You can connect to these in the same three steps mentioned above. Just ask the café owners/ customer service authorities to give you the password for the WiFi.

Remember that any public WiFi with no password protection is not safe. Hackers can easily intercept the data sent from your laptop/ mobile and hack your accounts or infect your device with malware.

Another strategy used by hackers is to setup a free WiFi with a rogue name that is misleading. So do not connect to any WiFi whose source is not known to you or is not trusted.
