5G NR Repeater Technology

Due to the nature that high frequency signals have high propagation loss, achieve deep in-building coverage for 5G is the new challenge for operators. Increasing the gNB (gNode B) power to compensate the propagation loss to acquire deep in-building coverage is unrealistic, since this may increase the coverage overlap among different gNB sectors, and cause interference which would reduce the SINR and affect the data throughput rate.
When Remotek’s NR Repeater is being used for 5G deep in-building coverage, good signal strength is assured, SINR enhancement which led to higher modulation scheme, higher coding rate, and ultimately higher data throughput in the coverage area is achieved.
Remotek’s NR repeater is equipped with unique features that allow it to adapt to the mobile network swiftly while minimizing the uplink interference at the same time.

Digital Repeater Technology

Digitized Repeaters support multiple channel amplification for 2G, 3G, and 4G systems, real time interference cancellation, isolation requirement reduction, and no uplink interference is generated from the digital repeater directly because of the signal digitization. The channel amplification and real time interference cancellation made it an ideal solution for complicated urban mobile network area, since interference to other cell sectors is minimized. The isolation requirement reduction is up to 30dB, this made the digital repeater easier to be applied for outdoor coverage, such as suburban, village, or isolated locations, since the vertical separation between the donor and service antenna can be reduced which means the pole or tower doesn’t need to be very high. Another benefit of the digitized repeater is that with no time synchronization problem, the Digital Fiber Optic repeater applications can be more flexible, and easily applied for most environments.
