GPRS(General Packet Radio Service)
GPRS (1).ppt (Size: 200.5 KB / Downloads: 60)
1. It is a new non voice value added service that allows information to be sent and received across a mobile telephone network.
2. It supplements today's Circuit Switched Data and Short Message Service
SPEED
Theoretical Maximum Speed Of up to 172.2 kbps.
It is about ten times as fast as current Circuit Switched Data services on GSM networks
It is less costly mobile data service compared to SMS and Circuit Switched Data
IMMEDIACY
1. It facilitates instant connections.
2. It is also referred as "always connected".
3. It is a very important feature for time critical applications such as remote credit card authorization
New Application & Better Application
1. Fully Internet application such as web browsing and chatting.
2. File Transfer.
3. Home Automation (the ability to remotely access and control in-house appliances and machines).
Service Access
1. To use GPRS, users specifically need’s mobile phone or terminal that supports GPRS.
2. A subscription to a mobile telephone network that supports GPRS, use of GPRS must be enabled for that user.
3. Automatic access to the GPRS may be allowed by some mobile network operators, others will require a specific opt-in knowledge of how to send and/ or receive GPRS information using their specific model of mobile phone.
4. GPRS users can access any web page or other Internet applications
Limitation of The GPRS
Limited Cell Capacity: There are limited radio resources and voice and GPRS both uses same network resources hence they impact the existing cell capacity.
Speeds Much Lower In Reality: The total bandwidth is divided among different user. Hence a single user cannot get the transmission speed up to 172.1 kbps.
Sub-optimal Modulation:GPRS is based on a modulation technique known as Gaussian minimum-shift keying (GMSK). EDGE is based on a new modulation scheme that allows a much higher bit rate across the air interface.
Transit Delays: GPRS packets are sent in all different directions to reach the same destination. Hence one or some of those packets to be lost or corrupted during the data transmission over the radio link.
No Store And Forward: There is no storage mechanism incorporated into the GPRS standard as compare to SMS.
