SATELLINE - 2ASxE

Radio Modem with high sensitivity

• Synthesized radio, 80 channels

• Frequency band in use +/- 1 MHz from the center frequency

• Selectable data speed 300 ... 4800 bps

• Compatible with SATELLINE-2ASx and 2ASxm2 modems
  

Meets Strict European Standard

The SATELLINE-2ASxE complies with the European Specification ETS 300 113. The user has a few available alternative channel spacings; 12.5 kHz, 20 kHz or the 25 kHz The frequency band in use is the center frequency +/-1 MHz, which means that the number of possible radio channels with channel spacing 12.5/20 or 25 kHz is 160/100 or 80, respectively. The maximum data speed is 4800 bit/s with channel spacings 12.5 and 20 kHz, and 9600 bit/s with the 25 kHz channel spacing.

Excellent Coverage

The output power of the transmitter is 1 W and the sensitivity of the receiver is -115 dBm, which gives an operating range of 2 to 40 kilometers, depending on local conditions as well as the gain and installation height of the antennas. A special version SATELLINE-2ASxE-LW is equipped with 200 mW output power, this model is excellent choise for shorter distences.

Repeater Function

In case there is a need to extend the coverage of the radio modem network, the SATELLINE-2ASxE radio modem can be used as a repeater station. In the repeater function, it receives a data packet (max length 135 bytes) and transmits it immediately further.

Application Domain

SATELLINE-2ASxE is primarily used for various local area data communications applications in industrial and urban environments. Thanks to its small size it can be easily mounted and integrated into fixed as well as mobile terminals. The RS-232 interface facilitates easy connection to the customers' terminals and systems.
