GPRS is a packet established instant conversation provider that provides facts charges from 9.05 up to 171.2 Kbps and non-stop connection to the web for cell phone and desktop clients. GPRS relies on GSM communications and enhances present providers akin to circuit switched cellphone connections and the quick Message provider (SMS).
GPRS represents the bridge among 2G and 3G cellular telecommunications and is usually known as 2.5G.
Implementation of GPRS calls for amendment of the prevailing GSM networks in that GSM is a circuit switched know-how whereas GPRS is packet orientated. GPRS permits packet information (the related as is utilized by an Ethernet LAN, WAN or the web) to be despatched to and from a cellular station - e.g. cellular phone, PDA or Laptop.
WAP and SMS can be despatched utilizing GPRS and contributors operating with GPRS have to research and know the way the cellular stations, the air interface, community structure, protocol buildings and signalling tactics has to be modified.
GPRS bargains a lot better facts charges than GSM and will be mixed with 3G applied sciences akin to part to provide even better bit-rates. It bargains many merits for patrons and community operators: comparable to quantity (rather then time) based billing and extra effective use of community resources.
Due to the global hold up in imposing 3G recommendations equivalent to CDMA and UMTS the call for for GPRS continues to be growing.
- Offers specific details starting from criteria to sensible implementation
- Answers 'how' and 'why' instead of simply easily re-stating GPRS specifications
- Provides finished insurance in one volume
Essential analyzing for all telecommunications undertaking managers, box engineers, technical employees in community operator and production firms, GPRS program and repair builders, Datacoms/IT engineers.
