RF Functionalities
The Radio Frequency (RF) functionalities of the AirPrime SL6087 Embedded Module comply with the
Phase II GSM 850/PCS 1900 recommendations. The frequency range for the transmit band and
receive band are given in the table below.
Table 1:
List of RF Frequency Ranges
RF Bandwidth
Transmit Band (Tx)
Receive Band (Rx)
GSM 850
824 to 849 MHz
869 to 894 MHz
PCS 1900
1850 to 1910 MHz
1930 to 1990 MHz
The Radio Frequency (RF) component is based on a specific quad-band chip that includes the
following:
Quad-band LNAs (Low Noise Amplifier)
Direct Conversion Receiver
Offset PLL/PL (Phase Locked Loop and Polar Loop) transmitter
Frequency synthesizer
Digitally controlled crystal oscillator (DCXO)
Tx/Rx FEM ( Front-End module) for quad-band GSM/GPRS/EGPRS

Operating System
The AirPrime SL6087 Embedded Module is Sierra Wireless Software Suite compliant. With the Sierra
Wireless Software Suite and the AirPrime SL6087 Embedded Module, customers can embed their
own applications with the AirPrime SL6087 and turn the AirPrime SL6087 embedded module into a
solution for their specific market need.
The operating system allows for the AirPrime SL6087 Embedded Module to be controlled by AT
commands. However, some interfaces in the AirPrime SL6087 Embedded Module may still not be
available even with AT command control as these interfaces are dependent on the peripheral devices
connected to the AirPrime SL6087 Embedded Module.
