Bouygues Telecom has teamed up with Ericsson to showcase over 25 Gbps in a aggregated throughput via 5G antenna system, with a latency in the order of 3 ms at the company’s Technopôle complex in Meudon-la-Forêt, France.
Both teams performed simultaneous data transfers via two devices where two 4K video feeds. It was conducted using two prototype mobile devices, which were simultaneously connected to an Ericsson radio base station equipped with active 5G antennas.
The demonstration showed the benefits of adaptive beamforming technology that combined with massive MIMO at centimetre-wave frequencies.
On a 4G network, all smartphones served by the same antenna must share the available bandwidth within that cell. With 5G, beamforming makes it possible to steer the radio signal in the direction of individual devices. As a result, each user has their own ‘mini-cell’, which moves with them and ensures they enjoy the highest possible bandwidth.
Alongside the demonstration conducted today at its own facilities, Bouygues Telecom is actively preparing its network for the arrival of 5G, planning the prerequisite operations and prototyping a number of preliminary 5G architectures and configurations such as upgrade of links to its radio sites with fibre-optic cable, rollout of the first elements of the Cloud RAN network, virtualisation of its core network and installation of urban micro-cells.
