2.1 

GPS Module 

The GPS receiver simultaneously tracks up to sixteen satellites and provides 
accurate satellite positioning data with fast time-to-first-fix (TTFF) with low 
power consumption. The highly integrated receiver achieves high performance 
and minimizes board size and power consumption requirements. 

The module provides complete signal processing from antenna to serial data 
output in NMEA messages protocol.  

The GPS device is fed and communicates with the EGPRS over a RS-232 
serial channel at a 9600bps baud rate. The GPS device holds the GPS receiver 
with an antenna on top of it.

GSM

 

operating frequency 

The EGPRS can operate over the GSM-900 MHz, DCS-1800 MHz and PCS 
1900 MHz bands: 

1. 

GSM-900, GSM-850:

 The unit in GSM-900/850 operating mode is of 

class 4, in accordance with the specifications, which determines the 
nominal 2W peak RF power (+33dBm) on 50 Ohm and sensitivity 
greater than -102dBm in all operating conditions. 

2. 

DCS-1800, PCS 1900:

 The unit in DCS-1800 operating mode is of class 

1, in accordance with the specifications, which determines the nominal 
1W peak RF power (+30dBm) on 50 Ohm and sensitivity greater than -
102dBm in normal operating conditions.
