Feature
Implementation
General
Incorporates MC52 iimodule

The MC52I module handles all processing for audio, signal and data within
The MC52I Terminal. Internal software runs the application interface and the
Whole GSM protocol stack.
Frequency bands
Dual band: GSM 900/1800MHz
GSM class
Small MS
Output power (according
To Release 99, V5)
Class 4 (+33dBm ± 2dB) for EGSM900
Class 1 (+30dBm ± 2dB) for GSM1800
The values stated above are maximum limits. According to Release 99, the
Maximum output power in a multislot configuration may be lower. The nominal
Reduction of maximum output power varies with the number of uplink
Timeslots used and amounts to 3.0dB for 2Tx.
