DIGITAL PORTABLE REPEATE

R800

The R800 is a compact and lightweight SFR DMR Repeater, designed for effortless portability and installation. It features the innovative Single Frequency Repeater (SFR) function, which enhances frequency efficiency by simultaneously receiving and transmitting on the same frequency. This capability ensures timely responses in emergencies by leveraging TDMA technology to rebroadcast two-way radio transmissions on the identical frequency. By utilizing DMR's dual time slots, the SFR can receive on one slot while transmitting on the other, making it an efficient solution for critical communication needs.

Single Frequency Repeater (SFR)
Single Frequency Repeater (SFR) technology leverages TDMA (Time Division Multiple Access) to simultaneously rebroadcast two-way radio transmissions on the same frequency. It achieves

this by concurrently utilizing the two time slots of DMR. Specifically, SFR receives on one time slot while transmitting on the other, enabling efficient and simultaneous communication on a single frequency.


Compact Design
Features a compact design with dimensions of 120 x 60 x 18 mm. Its lightweight and streamlined form factor ensures convenient portability, making it an ideal choice for expanding the coverage of mobile

communications in various settings.


Versatile Deployment Options
The R800 provides flexible usage configurations.It can be operated handheld on-site or mounted on various structures such as walls or drones to

meet specific operational requirements. This adaptability ensures effective deployment across a range of scenarios.


Extensive Applications
The R800 excels in extending last-mile signal coverage in commercial environments. Its cost-efficiency, ease of installation, and flexible deployment make it suitable for a variety of
settings, including office buildings, hotels,shopping centers, communities, schools,hospitals, and industrial sectors like mining and forestry, as well as large events.
