CCS (Cambridge Communication Systems Limited), developer of the world’s first self-organising small cell microwave backhaul system for mobile networks, today announces the results of a successful trial with China Telecom in its Anhui Branch. The system demonstrated self-organising multipoint-to-multipoint nodes over a range of distances in a dense metropolitan environment. The average installation time per node was only 15 minutes including site preparation, without the need to RF plan or align antennas. The result was a robust, redundant backhaul network running at 28GHz with high capacity and low latency for the backhaul of mobile base stations and small cells.
The trial network consisted of a single CCS node located at the China Telecom head office on the 8th floor and a mesh network of additional nodes at street level and on nearby buildings. Locations were chosen around the area to simulate a network with various ranges and configurations. The CCS nodes were quickly installed at all locations with minimal training.
Throughput and latency tests were conducted at each location to demonstrate 480Mbps per node and sub-150s latency per hop. One of the unique advantages of the CCS microwave solution is its ability to automatically self-organise a group of nodes into an optimal topology without the need to RF plan or align the radio links. The CCS nodes will automatically scan the surrounding area, and make connections to neighbouring nodes. The wired CCS node at the backhaul site acting as the partition manager will make decisions about routing in order to deliver capacity in the most efficient way. If a CCS node has multiple possible links between neighbours, self-healing will take place to recover and switch between routes should link conditions change. Configurations were tested from initial start-up and again once the optimal network topology had been achieved.
CCS CEO and co-founder Steve Greaves commented: “It is not just the benchmark results that impress, but also the ease with which we were able to demonstrate the solution. Our unique self-organising system is an excellent fit for the Chinese market, where small cell deployments are leading the world.”
