Question

what are GPRS and GRS in a cell phone ?

Answer 1

GPRS is General Packet Radio System (as mentioned before)...it's a way of transmitting data over the GSM data network efficiently. Normally if you wanted to establish a data connection, you took up an entire channel for the duration of your session. In GPRS, your data channel is only open when you're sending or recieving packets of data. This allows more people to use the data simultaneously because it's only handing out packets when needed.

GPS (as GRS isn't even in a phone i've seen) is Global Positioning Satellite (or system, depends who you ask)...it's a global network of low-orbit satellites that constantly transmit information that contains the current GMT time and it's location over the earth....using triangulation based on time offsets, GPS devices are able to pinpoint where they are on the surface. Newer phones contain GPS technology for navigation services, and some phones even slightly older contain one for E911 services, where the phone will try to get a position fix and use it if there's support. Some phones, like my Nextel, would let you pull up the GPS info at will.

General Packet Radio Service.

A packet-switched technology that enables data communications.

GPRS is used for various data applications on phones, including wireless Internet (WAP), MMS, and software that connects to the Internet. Basically, any network connection that is not voice or text messaging uses a data connection like GPRS, and assuming you mean GPS-

GPS (Global Positioning System) is a global satellite-based system for determining precise location on Earth.
