What is the Difference Between 4G and Wifi?

The main differences between 4G and Wi-Fi are related to their coverage, connection method, and usage:

1. Coverage: Wi-Fi is a local area network (LAN) technology that provides a wireless internet connection to devices within a limited range, typically up to 30 meters away from the router. In contrast, 4G is a cellular technology that relies on mobile phone towers to provide a wireless internet connection to devices over a wider area, such as cities and towns.
2. Connection Method: Wi-Fi connects devices to a router, which is connected to an internet service provider (ISP) via a physical line. On the other hand, 4G connects devices directly to mobile phone towers, which are in turn connected to the ISP.
3. Usage: Wi-Fi is mostly used for local access and is ideal for devices within the range of the router, such as laptops, smartphones, and tablets. 4G, being a cellular technology, is designed for use when on the move, such as when traveling on a bus or train.
4. Devices: Wi-Fi devices include a wide range of devices like TVs, speakers, refrigerators, laptops, smartphones, and tablets. In contrast, 4G devices are mostly mobile devices like smartphones and tablets, which require a mobile phone account to connect to the 4G network.
5. Speed: Wi-Fi networks are generally faster than 4G networks, especially when provided by a wired connection. However, with the introduction of 4G LTE and the upcoming 5G standard, cellular networks have significantly improved their speeds, offering rates as high as 1 Gbps or even 10 Gbps.

In summary, Wi-Fi is a local network technology primarily used for devices within the range of a router, while 4G is a cellular technology designed for use when on the move. Wi-Fi networks are generally faster than 4G networks, but the gap in speeds has narrowed with the introduction of advanced cellular standards like 4G LTE and 5G.

Comparative Table: 4G vs Wifi

Here is a table comparing the differences between 4G and Wi-Fi:

In summary, 4G/5G connected tablets offer mobile data connectivity, allowing you to access the internet anywhere with a cellular network. However, this comes with higher costs, increased battery drain, and potentially limited availability. On the other hand, Wi-Fi only tablets are more common, cheaper, and have a longer battery life, but they are limited to wireless internet connections.
