Highlights of Public Safety

Highlights of Public Safety
01
DMR and LTE Convergent Networking

Coordinated dispatching and unified command, DMR/ LTE Trunking hybrid grouping, and hybrid calls via the DMR and LTE convergent network.

02
Enhanced Coverage

The DMR system provides seamless coverage in urban areas to ensure the communication services and emergency handling. The LTE system fully supports Mobile Policing, Video Streaming, and Visualized Command in important places and key passes.

03
Wireless Broadband

The LTE provides a data rate of up to 100Mbps in the downlink and 50Mbps in the uplink. The signaling delay is shorter than 100ms, which ensures fast issuing of commands. The LTE is a perfect solution to the problem of last-mile broadband data access.

04
Safe and Reliable

End-to-end encryption and easy access to policing information system. The "2+4" system has been deployed and proven, satisfying the requirements of interoperability with other systems.

05
Smooth Evolution

Based on SDR platform, the system is analog and digital compatible, and can smoothly evolve towards LTE, hence protecting the customer's investment.


06
Leading-edge Technology

The system supports multi-carrier modulation; a single unit can support up to 4 RF carriers. The intermediate digital frequency combined with an external RF unit doubles system coverage. Industry-leading DPD and Doherty technologies improve amplifier efficiency and decrease power consumption by 80%.

Direct Mode Operations
Direct Mode Operations

Two-way radios enable users to communicate directly radio-to-radio bypassing the main network. Direct mode is normal operating procedure on the spot, but it is also very useful in tall buildings, tunnels, underground areas, and when operating beyond main network coverage in more remote areas.

Direct Mode Operations
Direct Mode Operations

The conventional system is an upgrade from the basic radio to radio communications. The radio communicates through high power repeaters with better coverage and faster response times.
