4G refers to the fourth-generation of cellular network technology, first introduced in the late 2000s and early 2010s. Compared to preceding third-generation (3G) technologies, 4G has been designed to support all-IP communications and broadband services, and eliminates circuit switching in voice telephony. [1]

In short, 4G is merely a marketing term. It means only that a network is faster than 3G. That's it. But there are different flavors of 4G, or mobile broadband. On the next page you'll see how 4G is different from its wireless forebears, and then delve into the details of what makes it so much faster than the first 3G systems.

How does 4G work? At the most basic level, a 4G connection works via an antenna that transmits over radio frequencies, enabling mobile devices to connect to mobile networks.

2024年2月12日 · 4G is known primarily for its broadband capabilities and significantly faster speeds than the former 3G, which introduced data connectivity into the cellular space.

4G essentially stands for ‘fourth generation communications system’ and it represents an upgrade from 3G by addressing the two major issues with the platform: speed and network congestion. Since it launched in late 2012, the platform has been adopted by all of the major UK phone providers, including Vodafone, 02 and EE. How does 4G work?

2021年8月2日 · Read on to learn what 4G is, why you should want it, and what all this means for the future of wireless. What is 4G? Don’t let this surprisingly intuitive naming scheme spin you …

4G, short for fourth-generation wireless, is the latest generation of mobile technology that offers faster download and upload speeds than its predecessors. It’s also capable of powering more data-intensive services such as video streaming and online gaming. 4G has revolutionized the way we experience the internet on our devices!

Defined by the International Telecommunication Union (ITU), 4G stands for "fourth-generation wireless," succeeding 3G and setting the stage for 5G. It is an all-IP-based standard for both voice and data, which streamlines operations for mobile network providers. While often used interchangeably, there is a distinction between 4G and 4G LTE.

2012年10月9日 · 4G networks use different frequencies to transmit data than 3G so you need a handset which has a modem that supports these new frequencies. Here, we’ll explain everything you need to know about 4G. We’ll be taking an in-depth look at how the technology works, where and when you can get it as well as telling you which devices support it.

4G is the fourth generation of mobile phone technology, following 2G and 3G. 2G technology was suitable for making calls and sending text messages, while 3G makes it possible to access the internet more effectively through your mobile phone.
