GPRS ISM SRD Gateway on embedded Linux

GPRS ISM SRD Gateway characteristics

Full Type Approved Quad Band Embedded M2M Module (GSM  850 /900 / GSM 1800 / GSM 1900) with  RS232 interface on CMOS level and AT command set.
This M2M module combines a GPRS module with an embedded PC on embedded Linux. One ARM9 is for customers M2M application and the second ARM9 is for controlling the GSM part. Thanks to the possibility of choosing among different ISM bands (433MHz, 868MHz, 915MHz and
2.4GHz), protocol stacks (ZigBee, M-bus or proprietary), network topologies (Star, Mesh, 802.15.4/ZigBee) and coverage (from 70m to 4km), time to market and total cost of the final application are significantly reduced.
