EE, the UK’s largest mobile network operator, has invested in a micro network technology that provides coverage to remote areas with no need for broadband or cables.
EE said it is committing to connect more than 1,500 rural communities within three years by using this technology. Starting in early 2015, EE will be making voice services, as well as 3G and 4G mobile data coverage available in communities that currently don’t have reliable mobile or high speed broadband.
These areas have remained unconnected by traditional approaches to network deployment that have relied on building large masts. To cover these communities, EE will build new micro networks that wirelessly connect small mobile antennas to a suitable nearby macro site, without the need for cabling, dramatically improving the economics of connecting hard to reach areas.
The first community to be connected through trials of the new micro network technology is the small village of Sebergham, in Cumbria. Sebergham has 129 dwellings and 347 residents, and sits in a deep valley.
Cumbria County Councillor, Duncan Fairbairn, said: “The mobile service here is either non-existent or spasmodic at best. And the broadband is incredibly slow and very unreliable. In rural communities like Sebergham, being connected to good, reliable mobile coverage can make a significant difference to everyday life and we need fast broadband.
“We’re delighted to be the first community in the UK to benefit from this EE initiative, and there are more villages in my parish that I know will benefit hugely from this, and they’re excited to be connected next.”
EE claims that unlike rival products, its rural micro network solution does not need any fixed broadband to connect into the wider network, meaning it can be deployed in more remote areas.
The micro network can connect communities of around 100-150 homes and businesses, across an area of 0.5 square miles with just three or four small antennas. An antenna can be installed on to any building in just a few hours, and planning applications are not required.
This low impact solution is based on technology designed by Parallel Wireless, and will be in full deployment in early 2015.
Rural areas can now be covered at lower cost by using smaller mobile sites that communicate with each other to spread coverage and capacity, and using wireless technology instead of cables to connect into the main EE network.
While wider geographical coverage improvements still require continued investment in the traditional macro network, this new technology enables more targeted voice and data coverage for small communities, at a lower cost of deployment.
EE CEO Olaf Swantee said: “With this innovative new technology, we have the capability to connect every community in the UK, and we estimate that we’ll be able to bring reliable voice coverage and high speed mobile broadband to more than 1,500 places for the first time by 2017.
“We’ve been working closely with Government on the long-term ambition to bring voice coverage to more of the UK, and we believe that this world-first technology will demonstrate significant advancements against that vision.”
Areas across the UK are being analysed now for connectivity, and the first deployments will be started in early 2015.
How the Parallel Wireless system works
Parallel Wireless, which is headquartered in the USA with offices in Inida and Tokyo, offers a converged wireless system (CWS). The CWS is a high capacity 3GPP compliant carrier-grade multi-RAT eNodeB that leverages the latest silicon to deliver more capabilities from commodity components.
Coming in different form factors including outdoor and in-vehicle, CWS delivers instant, reliable and cost-effective coverage anywhere and features:
• 4G/LTE and Wi-Fi
• Built-in flexible backhaul: Fibre, Ethernet, LTE Backhaul, multi-radio mesh SDN backhaul enabled by the company’s LTE Access Controller (LAC).
CWS leverages open APIs on the LAC. The nodes are self-configured and self-managed via LAC and can be deployed easily. LAC enabled orchestration provides hands free maintenance of CWS base stations along with the following benefits:
• SON-based interference mitigation for access and backhaul
• SON-controlled dynamic RF power adjustment
• Software-defined radio (SDR) capabilities that enable future proof for additional bands or band reconfigurations
• Integrated resilient synchronisation.
Parallel claims its LAC is the industry’s first carrier-grade, high-performance NFV- and SDN-based network orchestrator designed to meet the challenges of the HetNet over the next decade.
The LAC, which is fully 3GPP compliant, virtualises the RAN interfaces to manage all LTE RAN configurations in real-time while abstracting RAN changes from the packet core network and packet core network changes from the RAN.
As a result, the LTE Access Controller reduces the time and cost to build, optimise, secure, deploy and evolve the LTE RAN making deployment and maintenance of cellular 4G and 5G networks as easy as building Wi-Fi networks, according to Parallel Wireless.
The company believes its solution can be deployed in the following scenarios:
• Urban HetNet optimisation for VoLTE
• Rural and suburban network extension, urban infill, urban capacity enhancement
• Land Mobile LTE (LMLTE)
• “Bring Your Own Coverage” with in-vehicle instant deployables
• Hosting the 3G or P25 IP network backbones
• Greenfield macro with On-Tower Macrocell eliminating the eNodeB in the cabinet.
