GSM GPRS Upgrading

The deployment of GPRS allows carriers to upgrade their systems’ hardware and software (such as replacing or adding channel cards and adding packet switching nodes). Carriers can upgrade their GSM radio systems to offer GPRS and EGPRS services by simply exchanging, upgrading, or adding one or more of their existing radio channels to offer packet data services.

This figure shows how a GSM system can be upgraded to offer GPRS services. This diagram shows that an existing GSM channel is removed, replaced, or upgraded to have GPRS and EGPRS modulation and transmission capability. This diagram shows that packet control unit (PCU) must be added to the base station controller (BSC) and packet data switching nodes and gateways must also be added to allow data packets to be routed between mobile devices and data networks (e.g. the Internet or private corporate networks).
