Third-generation mobile network. The types of applications, capacity, and speed supported by the mobile network are based on the “generation” (G) of the network. 1G is an analog network and 2G is a digital personal communications service (PCS) network. Both are voice-centric, with the main difference in the voice quality, although 2.5G networks support some data services, such as mobile instant messages (IM) and push-to-talk (PTT) services. To date, most mobile broadband is offered via 3G networks, which offer improved voice quality, spectrum utilization, and additional data capacity. 3G networks typically support data stream rates of 3–14 Mbps. The next evolution is 4G mobile networks, which promise to deliver speeds up to 100 Mbps and are positioned to better support the applications and services of the near future than their hardwired brethren.
