GPRS, WCDMA, PCS, Networks Explained

[Mod]

Users can discuss and post their thoughts regarding the following cellular network options.

GPRS
General Packet Radio Service (GPRS) is a step between GSM and 3G cellular networks. GPRS offers faster data transmission (9.6Kbits to 115Kbits) via a GSM network. This enables users to make telephone calls and transmit data at the same time. For example, if you have a GPRS mobile phone, you will be able to make calls and receive email messages simultaneously.

The main benefits of GPRS are that it reserves radio resources only when there is data to send, and reduces reliance on traditional circuit-switched network elements.

WCDMA
Short for wideband CDMA, this is a high-speed 3G mobile wireless technology that can offer higher data speeds than CDMA. WCDMA can reach speeds of up to 2 Mbps for voice, video, data and image transmission. WCDMA was adopted as a standard by the ITU under the name "IMT-2000 direct spread."

PCS
Personal Communications Service (PCS) is the U.S. Federal Communications Commission (FCC) term used to describe a set of digital cellular technologies being deployed in the USA. PCS works over CDMA (also called IS-95), GSM and North American TDMA (also called IS-136) air interfaces.

Three of the most important distinguishing features of PCS systems are:
> They are completely digital.
> They operate in the 1900 MHz frequency range.
> They can be used internationally.

PCS is a second-generation mobile communications technology.
