With the evolution of technology, mobile internet has evolved. Most of the people are aware of the 2G, 3G, and 4G technology. However, in the near future, 5G will be the mainstream to allow seamless internet connectivity and high-speed browsing. In today’s connected world, we are somehow or another connected to the internet for different purposes. Whether it be downloading, streaming movies, playing games, project management or research, the internet has become an essential part of our daily lives.

One bitter reality is that staying connected to the internet is not 100% secure. However, there are some ways to enhance your security to remove data breach and privacy discrepancies. For this, you need to understand the technologies and risks associated with them.

How Smart Devices Connect to the Internet?

There are multiple ways to connect to the internet through your smart device. Let’s check them out.

4G Connections

4G enabled devices including smartphones and tablets to connect to the internet through a cellular connection. The major difference between a normal connection at home and the 4G connection is that data is received from the cellular company instead of an Internet Service Provider. The biggest advantage is that data sent through 4G is encrypted, which allows safer internet connectivity over public Wi-Fi.

Private Wi-Fi Connections

You are very well aware of Private Wi-Fi connections as they are commonly found in offices and homes. Private Wi-Fi connections are password protected if they are set up properly. Everyone who needs to connect to the internet requires inputting the correct password in order to access it.

Public Wi-Fi Hotspots

Public Wi-Fi hotspots are generally found in a place like hotels, malls, restaurants, airports, and cafes. Public Wi-Fi is though free to use but is not very secure to connect to the internet. Even if you find a public Wi-Fi under the trusted name, you can’t be 100% sure whether it is safe or not. However, if you are using Virtual Private Network to access the internet, you don’t need to worry at all.

4G Vs Wi-Fi VS Public Wi-Fi

4G internet is available through cellular networks like Sprint, AT&T, and T-Mobile. Whereas private Wi-Fi connections that you normally use at home are available through different ISPs – you can simply call Spectrum internet customer service to get more information and for placing an order as well. An ISP also backs public Wi-Fi, in order to facilitate commuters and passersby to use the internet on the go. However, they are not safe at all.

 Why You Should Not Use Public Wi-Fi?

As discussed earlier that Wi-Fi found in public places are not safe because they are not encrypted. However, if you compare it with your home network, the wireless traffic is encrypted between devices and the router. If someone is within the reach of Wi-Fi, he/she cannot peek into your browsing activity.

However, if you connect to the unencrypted network, everyone within the range can see your browsing activities. Even if you fill an online form.

What about 4G Connection?

If you want to connect your 4G enabled smartphone or tablet, it requires a cellular network. While browsing and socializing, your mobile data will be consumed and need to pay extra, if you exceed the limits. However, the best part is that data sent on a 4G network is encrypted, which allows safer accessibility over public Wi-Fi.

Although 4G can also be vulnerable to hacking but is safer than connecting to the public hotspots. Hackers who are well aware of the tools to hack a 4G network can access your data. While in the case of public Wi-Fi, free tools are available online to help hackers hack your data.

How to Ensure Safety on Public Wi-Fi

Let’s assume that you are traveling to another country without any mobile data. The only thing that would help you stay connected is through public Wi-Fi available at the airport. Now the question is how to stay safe because it is nearly impossible for you to book a ride on Uber without the internet. It is simple, just install a VPN on your device and browse as much as you like without revealing your identity.

A virtual private network or VPN encrypts your data and help you stay safe online, even if you are using public Wi-Fi. Moreover, if you are using a cellular network, VPN is still functional.


In this connected world, no one is safe. By taking appropriate steps, you will definitely prevent yourself from the wrath of hackers. Make sure to use public Wi-Fi wisely or prepare yourself for cyber threats and attacks.
