Connecting communities

With around 180,000 people living in the 6.3 square miles of the London Borough of Hammersmith and Fulham, demand for telecoms connectivity is massive and growing. The borough wanted to give residents, businesses and visitors access to the best mobile experiences, and partnered with Cellnex to make it happen.

In such a densely populated urban environment, network congestion was a major challenge – particularly during peak times, outside travel hubs and in pedestrianised areas around the borough.

As the concession holder with agreement to licence the borough’s street assets to MNOs, Cellnex worked closely with Hammersmith and Fulham to select the lamp posts columns in optimum locations. With the infrastructure mapped, Cellnex can now partner with MNOs to accelerate the deployment of Small Cells to deliver additional, street-level capacity in areas of high demand.

A sophisticated set up below and above ground

The lamp posts are connected by a brand-new 15km high density, multi-operator capable dark fibre network. This provides the bandwidth for MNOs to deploy advanced technology, including centralised C-RAN architecture and 5G. The network consists of a fibre ring with 90 shared cabinets and associated assets.

Cellnex provides and manages everything from the Small Cell site up to and including the point of interconnect (PoI). It coordinates all surveys and street works activities, and provides power to the cabinets. With the Small Cells live, Cellnex provides ongoing customer incident management, cabinet monitoring and operational reporting.

Deploying the solution

Working collaboratively to accommodate the differing MNO needs on the same network and in the same cabinets, Cellnex provides a list of available locations. This includes antenna type, bearing and system gains and losses at each location, and considers the spaces and operating frequencies in use by other MNOs. The MNO then identifies and validates all (or a selection of) the locations to suit its need – including where Small Cells and/or fibre connections may be required, together with the frequency bands they wish to operate.

Adding the cells

With the design agreed, the MNO connects to the PoI via dark fibre of its own choice, adds the Small Cell equipment as per Cellnex’s ‘Connected Street Infrastructure – Cabinet’ installation guide, and commissions and integrates the cell into its network.

Managing live operations

Cellnex then provides a complete management service – monitoring the cabinet environment for each live site, and providing ongoing incident management and operational reporting through its Service Desk. With this active monitoring and management of Cellnex-owned infrastructure in place, sites visits are managed, contractors coordinated for both planned and unplanned works, and incidents are quickly resolved – all in accordance to agreed service levels.

Key benefits

  • Shared infrastructure – enables lower costs and faster deployment. Cabinets for up to four MNO small cells with power provided
  • Built-in architectural resilience – in the unlikely event of a fibre break, half the sites would remain operational
  • Dark fibre backhaul network – to 2 Points of Interconnect (PoI) at BT exchanges
  • Shared infrastructure – omni or directional antenna with feeder system serving lamp columns. Cabinet space for MNO Network Termination Equipment
  • Cellnex Service Desk – incident management, ticket raising and resolution tracking
  • Easy ground level access – for equipment installation and maintenance
  • Flexibility – to support backhaul connection of other site solutions
