BT CEO Gavin Patterson, DT CTO Bruno Jacobfeuerborn, and FT/Orange SVP Arnaud Vamparys all endorsed Massive MIMO and said it would be used on their networks. I've added England, France, and Germany to the Massive MIMO map. They spoke one after the other at Huawei's Global Mobile Broadband Forum in London on November 14.
BT has a Massive MIMO rig in active testing. They only have 15 MHz of TDD 2.6 spectrum, although they have 50 MHz of FDD spectrum above 2.5 GHz. They are actively watching the development of FDD MM, especially as the 3.5 auction continues to be delayed. They could add roughly 70% to network capacity if OFCOM allowed them to switch the FDD spectrum to TDD. They support MM research at Bristol University.
Deutsche Telekom is trialing 3.5GHz Massive MIMO.
(Press release below.) DT has so much LTE capacity they are promoting hybrid boxes for DSL and LTE. They have carefully not promised any upgrades to the landline network to 20% of the population. That suggests they intend to do what AT&T & Verizon are planning: turn off the wired network in a large share of the country.
Orange/FT is doing their early work on Massive MIMO in their Romanian branch. It could be particularly important in Orange's dozen African networks. Because Africa has few wires, seriously expanded wireless capacity is the only way for a decent video-grade Internet.
Here's the pr from Huawei, Ericsson, British Telecom & Deutsche Telekom
Berlin trial shows throughput boost
- Commercial Sony smartphones fully integrated for the first time in the world
- Massive MIMO is a key technology for improving spectral efficiency to deliver greater network capacity
A former Deutsche Telekom telephone exchange in Berlin Schöneberg is actually turning into a hub for cutting edge technology developments. Only a few days after DT and Huawei unveiled Europe’s first pre-standard 5G connection there, the partners are announcing another breakthrough. They launched the fastest 3.5 GHz LTE TDD Massive MIMO field trial with 20MHz bandwidth at 3.5GHz band reaching 750Mbps. And in a world’s first, the trial uses fully integrated commercial smartphones – thanks to Sony, who modified some Sony Xperia Smartphones to support this trial. Combining massive MIMO and 256QAM, they set a new European record.
Improved spectral efficiency offers a route to higher network capacity. With its large-scale multi-antenna array, Massive MIMO can generate much more precise user-specific beam and utilize the multi-user beamforming technology to increase the spectrum efficiency by multiple times. Served by Massive MIMO, users will always have excellent experience and the cell capacity will be greatly unleashed even for the most crowded cells such as business centers, stadiums, squares, train stations, big events, residential areas or universities. Massive MIMO also provides a fast and effective coverage solution for high-rising buildings with its 3D-Beamforming capability in both horizontal and vertical directions. Above all with TDD spectrum, Massive MIMO can be well compatible with current LTE TDD terminals. During this field trial, commercial Sony Xperia XZ Premium Smartphones were used. They have been specially modified to integrate TDD capable at 3.5GHz spectrum. The outcome of this excellent cooperation: The world’s first 3.5GHz massive MIMO trial using commercial smartphones.
"Massive MIMO is an established LTE technology to achieve superb spectrum efficiency improvements", said Martin Bouchard, responsible for network strategy, technical planning and rollout at Deutsche Telekom in Germany. "It will also be a key technology for achieving greater efficiency gains in higher frequency ranges associated with 5GNew Radio. “We are very proud that Sony proved once again, in the great and long lasting cooperation with partner Deutsche Telekom, that our new technology flagship Xperia XZ Premium is a leading smartphone in the industry” said Izumi Kawanishi, EVP, Sony Mobile Communications Inc. “We have strong ambitions to continue that way with 5G as the next step”.
"3.5GHz is a major spectrum asset of Deutsche Telekom", said Wang Yang, Vice President of Huawei TDD product line. " This joint technical innovation is another big milestone in terms of long-term strategic cooperation between both parties, Huawei is quite happy to cooperate with Deutsche Telekom to unleash its great potential in 4G as well as 5G. Massive MIMO is an ideal companion for 3.5GHz band in terms of both capacity and coverage. We believe this joint innovation will bring technology advance as well as business success to Deutsche Telekom."
EE showcases end-to-end 5G network architecture with 2.8GBPS speeds
- EE’s end-to-end 5G network architecture delivers consistent 2.8Gbps download speeds in UK test lab
- Major step forward for network function virtualisation (NFV) with fully virtualised 5G core network on commercial-off-the-shelf hardware in the EE lab
- Cutting edge speeds achieved over active antenna unit with 64x64 Massive multiple-input and multiple-output (MIMO) broadcasting 5G New Radio over 3.5GHz test spectrum
EE, part of BT Group, today demonstrated 2.8Gbps download speeds across an end-to-end 5G test network in its UK mobile lab.
The breakthrough test, carried out in partnership with Huawei, linked the fully virtualised 5G core to the 64x64 Massive MIMO active antenna unit broadcasting 5G New Radio to deliver the ground breaking speeds.
The virtualisation of core network technologies for 5G – putting programmable software on commoditised hardware – reduces costs, increases efficiency, and allows for more flexibility in delivering new services.
The latest 5G breakthroughs are on show at the Huawei Global Mobile Broadband Forum, taking place 15 and 16 November, 2017.
Tom Bennett, EE Director of Network Services & Devices, said:
“We’re using our experience in cutting edge 4G technologies and our dedicated partnership approach to ensure technology leadership in 5G. The network architecture we’ve proven today is a huge step forward, and will drive our ambitious rollout timetable to be first for 5G.”
In order to deliver the consistent 2.8Gbps downlink throughput across the end-to-end 5G architecture, EE linked its fully virtualised 5G core network to 100MHz of 3.5GHz test spectrum via the proof-of-concept Huawei 5G baseband unit. The consistent 2.8Gbps speeds and sub 5ms latency were delivered end-to-end, rather than just across the air interface.
EE’s 5G architecture is aligned to Option 3 of 3GPP Release 15, due to be finalised next month and formally ratified in April 2018. 3GPP Release 15 will be the first official, global standards for how 5G will be built.
The 5G firsts have been achieved by the EE and BT engineering teams working in strategic partnership with Huawei.
