What is a 3G service?
High -speed access to voice and data technology is known as a 3G service because it is considered the third generation of cellular telecommunications technology. 3G network is required for this service. It offers 1G and 2G network, such as multimedia applications such as video and broadband services. The telephone service itself benefits from a better range and wider availability. In addition, data transfer speeds are better than dialing speeds and more in accordance with cable modem technology.
The minimum speed for stationary user is 2 megabits per second. When users get 348 kilobites per second in a moving vehicle. In ideal conditions, the 3G downloading speed service provides 14.4 megabites per second. The recording speed is around 5.8 megabites per second. Three layers of information are sent by this process. The first layer is real voice information. The second layer is a control transmission that maintains high quality. The last layer is basic information about thea bond that prevents drained calls.
While there are a number of similarities between WiFi technology and 3G services, there are several different differences. WiFi has been created to allow data transfer with high bandwidth in short range transmission. This makes it ideal for local connection to larger networks. 3G networks use large satellite connections that connect to the telecommunications towers. This means that the range is much greater than other technologies.
The first countries to implement this service option were Japan and South Korea, where 3G now represents almost 70 percent of networks. Europe and North America, namely companies in the United States and the United States, have also implemented these services to most commercial customers.
Many countries such as China and Indonesia have delayed the implementation of 3G service due to licensing restrictions and total system costs.2G uses another radio frequency, which means that all new devices and infrastructure are required to use this service.
There are also a number of security concerns about this service. Communication to Mobile-Mobile uses encryption to maintain communication and exchange data before eavesdropping. The 3G network size and range demanded a new technique known as Kasumi Block Crypto. This encryption has many weaknesses over its predecessor, A5/1 Stream Cipher.
