Bouygues Telecom has partnered with Ericsson to demonstrate 5G download speeds topping 25Gbps at a French innovation day.
Bouygues used two prototype mobile devices, simultaneously
linked up to an Ericsson base station, to show off data
transfers with an average throughput surpassing 25.2Gbps and a
latency of just 3ms.
It is one of a number of demonstrations and upgrades for the
French operator as it prepares for 5G. It is also upgrading its
sites with fibre links, rolling out cloud RAN network
technology, and virtualising its core network.
"Having established its leadership in France 4G technology,
Bouygues Telecom intends to maintain its technological lead
with the rollout of 5G planned for 2020," said Yves Legrand,
chief technical officer, EVP at Bouygues Telecom.
Ericsson’s 5G antenna used beamforming
technology and massive multiple input, multiple output (MIMO)
at centimetre-wave frequencies, allowing the Swedish vendor to
direct specific signal at each of the devices individually.
This, according to Ericsson, allows each device to have its
own "mini-cell", moving with them, giving the highest possible
"In evolution of existing 4G networks, 5G will enable us to
meet demand for very high-speed mobile broadband capacity,
support massive interconnection of IoT devices, and achieve the
ultralow latency required for critical connections between
machines and with vehicles," said Franck Bouétard, head
of Ericsson France.
"5G is also an excellent opportunity, as we have shown with
Bouygues Telecom, to deliver ultra high-definition video
streaming and virtual and augmented reality to mobile devices
Ericsson is attempting to position itself at the forefront
of 5G, which is expected to be deployed globally from 2020
onward. At this year’s Mobile World Congress, it
demonstrated remoting driving from 70km using 5G in a
partnership with Telefonica.
Ericsson has also teamed up with BT and Kings College London
to launch a 5G partnership in the UK.
