What are the basic features of 2G?

Digitally encrypted phone conversations, at least between the mobile phone and the cellular base station but not necessarily in the rest of the network. Significantly more efficient use of the radio frequency spectrum enabling more users per frequency band. Data services for mobile, starting with SMS text messages.

Which technologies are used in 3G and 4G?

The technology used in 3G is WCDMA(Wideband Code Division Multiple Access). The technology used in 4G is LTE(Long-Term Evolution), and WiMAX(Worldwide Interoperability for Microwave Access).

What multiple access techniques is used by 3G?

Third generation cell phone technology uses code division multiple access (CDMA). 4G cellular communication system uses advance version of FDMA scheme i.e. OFDMA (Orthogonal Frequency Division Multiple Access). This generation uses packet switching method for data transmission.

What speed is 3G?

3 megabits per second
The average speed of 3G connections is 3 megabits per second (Mbps), which was 30 times faster than 2G average speed of 100 kilobits per second (or 0.1 Mbps). Some 3G connections could achieve speeds of 7Mbps.

What are the features of 3G technology?

3G technology features can be divided into two categories which are the data rates & the security , The main feature of 3G technology is that it supports greater voice & data capacity and high data transmission at low-cost , 3G mobiles can operate on 2G and 3G technologies .

What is the difference between 2G and 3G network?

• 2G has narrow bandwidth. 3G network offers wider bandwidth. This enables 3G to carry more data at more speed. • 2G is voice centric. 2G was made with the main goal of voice communication. 3G is multi media centric, wich means it has a primary job to carry out data.

What is 3G broadband?

Later 3G releases, often denoted 3.5G and 3.75G, also provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. This ensures it can be applied to wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV technologies.
