It has a transmission rate of at least 200 kilobytes per second for information transmission. It is faster than the previous version and supports less than 200 kilobytes per second.

Accessing the Internet using the 3G mobile network is 3G Internet. The 3G mobile network can be accessed by a mobile device which can be a cell phone or a PDA. Because 3G Internet uses third generation technology, users can access large amounts of data at high speed. Compared with other technologies for accessing the Internet, 3G technology is at a higher position. There are many devices that provide the functionality to use 3G technology. To access the 3G Internet, some specific devices are smaller and more compact than normal desktops and laptops. Most 3G Internet is accessed via mobile phone. Therefore, access to the Internet depends on the size and model of the mobile phone. Because mobile phones have more features, you can easily access web pages to see normal sizes. Otherwise, the application interface view will be smaller.

3G technology has better features than previous mobile network technologies. 3G is used by mobile phones to connect phones to the Internet and other IP connections, can access voice calls and video calls. Not only that, it helps to download and bring it online. The third generation Universal Mobile Telecommunications System (UMTS) can also provide high data rates of up to 384 kb / s for wide area applications and even high data rates indoors 2 Mb / s. This is accomplished by using a wideband signal (W - CDMA) with code division for multiple access. User data is multiplied by a fast pseudorandom spreading sequence before the phase modulated radio frequency (RF) carrier. As a result, the broadcast result signal has a bandwidth of about 5 MHz.

The biggest advantage of 4G mobile phones beyond 3G technology is a significant increase in network bandwidth and capacity. For example, on a 3G network, mobile users may need a WiFi connection to enable video calling via Skype or other equivalent technology. On 4G phones, most cell phone companies can support live video on cellular networks. In addition, 4G mobile devices can include 'always on' service such as GPS, location information service etc GG also includes support for traditional 3G phones, but older phones can not achieve data download / upload speeds. Finally, mobile phone architecture is inexpensive to deploy and maintain at a mobile phone company. If the underlying switching system is modified to support flat IP addressing, the total cost of the 4G network will be lower than the total cost of traditional 3G or 2G.
