Application Background

TETRA (Terrestrial Trunked Radio) is a set of standards developed by the European Telecommunications Standards Institute (ETSI) that describes the mobile communications infrastructure throughout Europe. This infrastructure is primarily intended to meet the mobile radio needs of public safety agencies such as the police and fire departments, utility companies and other businesses that provide voice and data communications services.

LTE (Long Term Evolution) is a long-term evolution of the Universal Mobile Telecommunications System (UMTS) technology standard established by the 3rd Generation Partnership Project (3GPP). The LTE network has the ability to provide a download rate of 100 Mbit/s and an upload rate of 50 Mbit/s. In the E-UTRA environment, delays below 5ms can be achieved with QOS technology. LTE can support communication needs in high-speed mobility, supporting multicast and broadcast streaming. Huawei provides eLTE broadband cluster solutions to enterprise customers based on leading wireless technologies, including professional broadband clusters, video surveillance, data acquisition, broadband data access, emergency communications and other professional services to help corporate customers improve operational efficiency, solve network deployment problems in harsh environments, to create a safe society.

DupliCALL’s wireless intercom voice and video system can perfectly support TETRA 800m trunking and Huawei eLTE broadband trunking, providing full recording and unified management of voice dispatching (such as point call, group call, broadcast, and emergency call) and visual dispatching (limited to Huawei eLTE).

Deployment Scenario Advantages

  • Traditional deployment Scenario

 
  • The challenges of the traditional deployment scenario:

Only supports group call recordings

Cannot search by interphone ID

Multiple points need to deploy multiple servers, high cost

Each call group needs one analog output basic unit

Most of the latest wireless intercom recording solutions do not provide the basic analog output unit
