CCS expands deployment with China Mobile
China Mobile – the world’s largest mobile network operator – has expanded its deployment of Cambridge company CCS’ small cell backhaul technology with a new installation in its Fujian Mobile branch.
Formerly known as Cambridge Communication Systems Limited, the UK specialist is creator of the world’s first self-organising small cell microwave backhaul system for mobile networks.
It was in February that China Mobile began implementing CCS’ backhaul system to deliver enhanced coverage and capacity in a busy urban environment of Beijing, in one of its first outdoor deployments of 4G LTE-TDD small cells.
Now the operator is rolling out the CCS solution in the busiest commercial area of Longyan, to backhaul the latest LTE-TDD small cells from ZTE.
A CCS unit is installed at an existing macrocell site, which feeds down to the street to provide a high availability, low latency and high capacity Ethernet backhaul service in excess of 200Mbps to each small cell site.
The environment is extremely challenging for both RF and GPS – narrow streets with densely packed, tall, reflective buildings on both sides and a poor view of the sky.
The CCS system’s self-organising capability enables it to pick up the optimal signal, thereby overcoming RF issues. Each CCS node is also uniquely capable of providing GPS-derived synchronisation to the small cell when the small cell’s own GPS fails.
The GPS capabilities of CCS’ backhaul system are much more robust than those of a small cell, enabling operation in difficult environments where small cells may not function.
The Fujian network was deployed by local contractors in just one day after minimal training, without the need for any on-site configuration or manual alignment.
The advanced self-organising nature of the CCS backhaul nodes has created a network that can self-configure into an optimal topology – without any RF or link planning – and provide automatic redundancy via self-healing features.
CCS CEO Steve Greaves said: “This expansion of our commercial partnership with China Mobile really underlines how successful our solution is proving to be in delivering robust backhaul in difficult urban settings.
“The unique, built-in intelligence of our system means that these networks can be deployed quickly, flexibly and reliably in even the most challenging RF and GPS environments.”
