1.4 MTX-IND-V2 Wireless modems in a Communication System
Figure 1 and Figure 2 illustrate the main blocks of a wireless communication system using the wireless
modem. Figure 1 shows the communication system when a micro-controller is used. They also show the
communication principles of the system and the interface between the wireless modem and the
application. Figure 2 shows the communication system when the JAVA application is embedded on the
wireless modem. The definitions in the figures, as used elsewhere in this manual, are in accordance with
the recommendations of 3GPP TS 27.007.
The MS (mobile station) represents the wireless modem and SIM card. The wireless modem excluding SIM
card is known as the ME (mobile equipment).
The DTE (data terminal equipment) is the controlling application. This can be either an external host or an
internal embedded application.
The DCE (data circuit terminating equipment) is the serial communication interface of the MS.
