Small cells will give London data capacity it needs

London is to get a small cell backhaul network which will provide businesses in the city with up to 1Gbit/s internet access.

The network will be created and managed by Luminet and will deploy small cell wireless basestations developed by CCS.

The advantage of a backhaul network of small cells it is more spectrum efficient and will provide operators with increased mobile data capacity.

Small cell networks are also expected to be an element of future 5G network deployments.

Although small cells are recognised as the ideal solution for operators to cope with the increase in mobile data, deployment is often hindered by site acquisition and associated planning approvals. However, Luminet already has more than 1,900 sites in London via its fixed wireless access infrastructure.

Luminet also has two clean 112MHz frequency channels in perpetuity at 28GHz for the M25 region, to be used by the CCS Metnet small cell network system.
Sasha Williamson, CEO, Luminet, writes:A 3D map data will be used to identify demand hotspots in the capital for on-net delivery with a resolution of less than one metre.

“London mobile network congestion is hitting a crunch point – it is one of the most digitally dependent cities in the world and is the epicentre of the UK’s digital economy, which is growing 32% faster than the rest of the economy. In order for the city to retain its competitiveness on a global stage, having the necessary digital infrastructure is paramount.”

The Small Cell Forum anticipates a demand of 0.01 GkM for urban peak data density in London.

However, according to Mobile-Experts.Net, this demand has already reached 0.015 – 0.02 GkM (Gbps/Km2/MHz) for some hotspots in London.

This wireless backhaul network from CCS and Luminet, utilising the new 3D hetnet mapping capability, is planned for 23 partitions and 250 polygons across 1050 small cell sites, enabling a transit capacity of 0.012 GkM (Gbps/Km2/MHz).

“This will be one of the first self organising networks in a Tier One global city, and by adopting a neutral host strategy we are enabling how mobile operators can scale with the ongoing increase in mobile data demand in urban areas,” said Williamson.
