Figure 2: Main Blocks in a Wireless System (external micro-controller)
In accordance with the recommendations of ITU-T (International Telecommunication
Union - Telecommunications Standardization Sector) V.24, the TE communicates with
the MS over a serial interface.
The functions of the Wireless CPU follow the recommendations provided by 3GPP (3rd
Generation Partnership Project) and ITU-T. 3GPP is a collaboration agreement that
was established in December 1998. The collaboration agreement brings together a
number of telecommunications standards bodies which are known as Organizational
Partners. The current Organizational Partners are ARIB, CCSA, ETSI, ATIS, TTA, and
TTC.
3GPP specifies a set of AT commands for controlling the GSM element of the Wireless
CPU; these commands are supplemented by Wavecom specific commands.
To find out how to work with AT commands, see the AT Commands Manual.
