The D.E.S.K. GPRS Channel features:
* Supervised Two-way Wireless communication.
* No range limit. Operating from everywhere with GSM/GPRS coverage.
* Very fast Event transmission: 2-5 seconds for Event Transmission + Acknowledge from the Central Alarm Monitoring Station (CAMS) - comparable to 2-way Long Range Radio transmission. Much better that One-way Radio (for multiple messages) and Tel. Channel transmission speeds.
* All GPRS End Units are fully supervised. Supervision signal interval can be individually programmed into each End Unit (the GPRS Server is automatically updated with the data - by the End Unit).
* Very efficient message encoding allows 5 minutes Supervision signal interval with only 1 Mbyte/Month of total data traffic (including the TCP/IP overhead).
* Full End-Unit status report on each Supervision signal, including I/O status, Power & Battery status, and GSM Received Signal Strength (RSSI) at the End-Unit.
* Full Upload/Download of all Parameters and Status Request Report - over the GPRS channel.
* Remote Control of End-Unit outputs via the GPRS channel.
