Huawei has announced the launch of the RTN 5100, a point-to-multipoint microwave backhaul radio. The system is designed to provide twice the transmission capacity of the company's prior generation hardware.
Why it matters
This hardware update increases backhaul capacity in network environments using unlicensed spectrum. The deployment allows operators to expand throughput without acquiring additional licensed frequency bands.
The RTN 5100 operates within the 5 GHz unlicensed band and delivers a 2x increase in transmission capacity compared to the previous model. The hardware includes native support for AES256 over-the-air encryption.
The players
Huawei
A global provider of telecommunications infrastructure, mobile devices, and networking hardware with a focus on wireless backhaul and 5G deployment.
The details
The RTN 5100 utilizes TDMA (Time Division Multiple Access), a channel-access method that segments a carrier frequency into periodic time frames. By organizing the transmission window, TDMA allows multiple remote endpoints to take turns sending data to a single central base station. This coordination prevents signal collisions while managing data flow across the 5 GHz spectrum.

The Tech Race
The RTN 5100 represents an incremental advancement in point-to-multipoint wireless infrastructure, pushing the capacity limits of unlicensed 5 GHz bands. This launch follows the established trajectory of microwave backhaul development, where efficiency gains in scheduling algorithms serve as a primary competitive lever.
Network operators can utilize this hardware to increase data backhaul throughput in areas where unlicensed spectrum is already in use. The transition to this new system requires upgrading existing hardware to support the updated TDMA scheduling and encryption standards.
The takeaway
The move toward increased capacity in the 5 GHz band highlights the industry's focus on squeezing more performance out of non-exclusive frequency ranges. Engineers should watch for the release of comparative throughput benchmarks to verify the 2x performance increase claims.
