Mobile Broadband

To understand Mobile Broadband it is important to understand the terms broadband and mobile separately first.

Mobile access technology is a technology used for communication; to transmit data between network element and user device via radio frequency waves. In order to facilitate the service continuity, network infrastructure is required to manage radio resource and mobility. The information data is routed via different network elements in the infrastructure. Example of this type of network infrastructure are GSM Network Evolution (WCDMA, HSDPA, HSUPA, HASP) or CDMA Network Evolution (CDMA2000 1X EV-DO, EV-DO Rev A, EV-DO Rev B, Flash OFDM).

Broadband is the system of sending and receiving small packets of data, from one computer to a server computer and hence forth. Conventionally this data would get transferred using cables with optical fiber. Data flows via these cable wires like packets of information and get delivered and vise versa.

Increasingly sophisticated technology in modulation technique and cellular network architecture provides a platform for data to be delivered via cellular radio network in a more power and spectrum efficient way. Its objective is to provide continuous wireless access to packet data networks. However from the data rate and latency performance perspective, it is quite close to the fixed broadband access; such as cable modem and ADSL.

The advantages of mobile broadband are numerous: simply a user can be connected on the move:- everywhere and anytime.

EvDO provides very high data throughput, with a theoretical maximum speed of about 2 megabits per second. HSDPA speeds theoretically can reach 3 mbps and faster--so fast that some people call HSDPA a "3.5G" service.
