Metnet product specification

Metnet nodes connect autonomously to form flexible MPtMP (mesh) self-organising (SON), self-healing links that dynamically reconfigure to optimise performance and spectral efficiency as LOS or NLOS circumstances or traffic levels change. The CCS Metnet system enables microwave deployment in a flexible, organic way allowing customers to start small and grow as they go.

Applications include:

Small cell backhaul (3G, 4G LTE, 5G)
Public Wi-Fi backhaul
CCTV backhaul
FWA (fixed wireless access)
Fiber extension, protection & redundancy

The Metnet system operates in a single frequency channel with no radio frequency planning required. Frequency reuse in the entire network is 1. Each node has a wide 270-degree field of view, so only one unit is required per site, rather than multiple radios. There’s no need for any manual alignment and each node supports multiple connections for higher resilience.

The nodes poll the network continually and automatically determine the optimal topology to deliver capacity where needed. Each cluster runs a Spatial-TDMA transmission schedule, which allows links to operate simultaneously to increase the overall capacity delivered to each node.

1.2 Gbps throughput is achieved by using a by using a dual channel TDD radio (in a single 112 MHz channel pair) operating at 256 QAM modulation. The radio features a wideband diplexer which is SW configurable for any channel between 24-29 GHz.
