DMR TDMA 2 time slots on a 12.5kHz single frequency channel
It provides group call, private call and emergency call on one slot, and used the other slot to provide versatile data services, such as Text Message, Patrolling Checking(RFID), Location Positioning and Tracking (GPS for outdoors and RFID for indoors), and can make dispatching and remote controlling over the same frequency.
Patrolling Checking RFID
With planned RFID checkpoint and RFID radio, can set rules for users in patrol group, can set the route, start time, arrive
time, duration, required working days in the week or in the calendar. And a result of patrol statistic will be calculated automatically by the system.
Location Positioning and Tracking GPS
You can track vehicles and assets without additional equipment to purchase, install or maintain. It can send location information to dispatcher systems and you can view GPS positioning information.
Roaming Function
Create wide area coverage and automatically roam from one coverage area to another with no manual intervention.
IP67 for dust & water protection
Dustproof and splashproof, so you can work with confidence in challenging environments.
Geo fence
An alert will be given to control center if he goes out the boundary of the fence, or doesn't have any movements for a set period.
Device user level management, terminal dispatcher
Different user level can be set (commander, level1/2/3 user etc.)to fit different communication scenarios and dispatching priority.
