EE and BT showcase 'pre-standard 5G' to connect Air Mast

• EE first UK mobile operator to showcase ‘pre-standard 5G’ backhaul capability, using its patent pending 4G air mast
• 26GHz test spectrum used to carry traffic from 4G air mast as part of Adastral Park Innovation Week event
• ‘Pre-standard 5G’ backhaul solution increases 4G speeds and lowers latency

EE, the UK’s largest mobile network operator and part of the BT Group, has become the first UK provider to successfully demonstrate pre-standard 5G backhaul technology, using it to connect its unique Helikite ‘air mast’ mobile coverage solution.

EE’s patent-pending Helikite solution uses mini mobile sites attached to a helium balloon to provide 4G mobile coverage where permanent sites have been damaged by extreme weather and other disasters, or in areas where there is no 4G coverage. The addition of pre-5G backhaul increases 4G speeds and lowers latency, which increases the number of people that the air mast could keep connected, and gives them a faster internet connection.

Marc Allera, EE CEO, said:

“Innovation is what drives advances in technology, and it’s what keeps making UK consumers’ experience of mobile better and better. The EE network will go from strength to strength thanks to BT’s incredible R&D capabilities and our commitment to delivering what our customers need. Today’s demonstration is a great example of that: we know that we need better solutions to keep customers connected in the most rural parts of the UK and during disasters, and we can make that solution even more powerful by developing ground breaking pre-standard 5G technology.

“This is not 5G, but it is a technology that’s an important stepping stone to 5G. We’re working hard to adopt the principles and the technologies that will become 5G, and to showcase what benefits these can bring to our customers.”

Today’s demonstration is an example of the potential applications and customer benefits of BT and EE’s 5G research activities which are being progressed well ahead of the deployment of future 5G networks.

The ‘pre-standard 5G’ backhaul technology – demonstrated for the first time today at BT’s Innovation Week at its labs in Adastral Park, Ipswich – uses millimetre wave (mmWave) frequencies, regarded as one of the main building blocks of future 5G technology.

By applying the technology to deliver the mobile backhaul requirements for EE’s recently announced 4G Helikite solution, EE and the BT Labs have proven the potential for delivering even faster 4G speeds and lower latency using mmWave.

The innovative mobile backhaul solution demonstration uses 26GHz test spectrum to connect the Parallel Wireless small cell on the Helikite to an Athonet virtualised Evolved Packet Core (EPC) on the ground using a PHAZR link.

EE and BT Labs are taking a leading role in developing technologies that will play a role in delivering future 5G mobile networks, including mmWave, Massive MIMO and network slicing – a new method of carving out specific ‘slices’ of an IP based network to support dedicated services delivered over future 5G networks. EE and BT are working towards enabling 5G in alignment with standards that will be set by mobile standardisation body 3GPP as part of their Release 15 update, which is scheduled for 2018.
