with powerful functions and convenient configuration, meeting customers' higher requirements. It is a key part of different PMR solutions for different scenarios.
Digital Repeater
PR900 adopts 1U design, making the height half of conventional repeaters and saving space when installing.
PR900 adopts a 2.0-inch HD color screen, making it more convenient for users to review information and operate.
Digital voice processing reduces the impact of environmental noise on voice quality, making the call voice clearer. Thus, it is suitable for complicated and noisy work scenarios with constant changes.
Smart digital-analog automatic detection mechanism ensures legacy analog radios can still be used under our PR900, to guarantee customers' historical investment to the greatest extent.
PR900 analogue repeater supports flexible networking based on diversified scenarios: IP connection extends coverage; simulcast fulfills large coverage with fixed frequency; active link offers wide coverage; ECS(Enhanced Conventional System) realizes dynamic channel allocation.
Professional encryption algorithms as well as service protection mechanisms such as authentication and remote stun, help to ensure the data security and reliability of the DMR system and the end user's life safety to the utmost extent.
PR900 supports the access of the remote microphone and provides a customization interface to realize more third-party extension services.
With DMR two-slot TDMA technologies, PR900 allows a single carrier with a bandwidth of 12.5 kHz to support two independent calls, with each time slot occupying a bandwidth of 6.25 kHz, which reduces transmission time in half and saves battery power consumption by 40%, effectively prolonging the standby time of DMR radios.
As Caltta is a member of the DMR Association, the PR900 repeater is fully compliant with DMR standard and can interconnect with any other DMR system and radios that comply with DMR standard.
Besides basic PTT services, PR900 also supports text messages, status messages, map-based location services, and call recording to enrich the user experience.
Supports customization according to customer needs.
