Question 17

Discuss and differentiate the different generations of mobile communications technologies.

Accepted Answer

PCS are second-generation (2G)mobile communications technology,and analog cellular systems are first generation (1G).Second-generation cellular networks are circuit-switched digital networks that can transmit data at about 10 kilobits per second (Kbps),which is extremely slow.Third-generation (3G)networks use a newer packet-switched technology that is much more efficient (and hence faster)than dedicated circuit-switched networks.Third-generation networks have speeds ranging from 120 to 144 Kbps for mobile users in,for example,a car,and up to 2 gigabits per second (Gbps)for stationary users.These 3G networks are designed for high-speed transmission of multimedia data and voice.The major network operators are providing 3G services,and some groups and companies have already started working on fourth-generation (4G)mobile phone system.The 4G technology will take mobile communication another step up to integrate radio and television transmissions,and to consolidate the world's phone standards into one high-speed technology.
