Description
Overview UHF GPRS Data Transmission Terminal
This UHF wireless GPRS/SMS data transmission terminal is embedded with a highly reliable ARM7 CPU. Its design ensures high quality data transmission over a wide temperature range, vibration and electromagnetic conditions.
It features EMC an anti-jamming design and is widely used in unattended device operation, remote monitoring, remote data acquisition, and remote AMR. It can also be applied to electric power automatic systems, industrial monitoring, traffic management, atmospheric monitoring or pipeline network monitoring.
