Verizon and Ericsson reached another milestone in 4G LTE Advanced Technologies that will also serve as a stepping stone to 5G technology by completing their first deployment of FDD (Frequency Division Duplexing) Massive MIMO (Multiple Input – Multiple Output) on Verizon’s wireless network in Irvine, CA.

This deployment will improve both spectral and energy efficiency, increasing network capacity for current devices in the market.  Further significant enhancements are expected to come as new devices evolve toward 5G.  For customers, the result will be higher and more consistent speeds for using apps and uploading and downloading files.

“While continuing to drive 5G development, the deployment of Massive MIMO offers very tangible benefits for our customers today.  As we innovate, we learn and continue to lay the groundwork and set the standards for 5G technology,” said Nicola Palmer, Chief Network Officer of Verizon Wireless.  “Our collaboration with Ericsson on this new deployment continues to drive industry-wide innovation and advancements.”

Today’s Massive MIMO deployment involves 16 transceiver radio units driving an array of 96 antenna elements supplied by Ericsson.  The deployment is running on a 20 MHz block of AWS spectrum.  Four way transmit has been widely deployed throughout the Verizon network and has contributed to significant 4G LTE advancements.  In Massive MIMO – the next step of antenna array evolution – the high number of transmitters enables more possible signal paths.  It also enables beamforming, which directs the beam from the cell site directly to where the customer is, dramatically cutting down on interference.  Reduced interference results in higher and more consistent speeds for customers.

Niklas Heuveldop, Head of Market Area North America at Ericsson, said: “Massive MIMO is a key technology enabler for 5G, but already today, 4G LTE service providers and end users can benefit from the superior capacity and network performance this technology enables.  The current trial is an important step in the collaboration we have with Verizon to prepare their network for 5G.”

As part of an Intelligent Edge Network that processes data where it’s generated, this Massive MIMO deployment is another step in technological innovation and leadership. As Verizon begins deploying Massive MIMO in the future throughout the network in places where there are capacity needs, customers with compatible devices will automatically begin taking advantage of this technological advancement.

  • Ericsson has been selected to provide Massive MIMO and Carrier aggregation technology to help Vodafone UK evolve its 4G network in southern England
  • In addition, Ericsson has been selected to provide Vodafone UK with 5G Radio technology to prepare for the introduction of 5G in the region

Vodafone UK has selected Ericsson  to evolve its 4G networks in London and southern England using technologies such as Massive MIMO and Carrier Aggregation, which will help deliver improved capacity and end-user performance.

Massive MIMO technology utilizes advanced antenna arrays to improve the quality of radio signals and capacity, while Carrier Aggregation combines different cellular frequencies to increase capacity and user data rates.

The scope of the agreement includes technology trials, product validation and commercial deployment, as well as professional services.

Jorge Fernandes, Technology Director, Vodafone UK, says: “We are continually enhancing our network to optimize performance and give our customers the best possible experience. We will continue to expand our 4G network and develop greater capabilities for our customers. We look forward to continuing to work with Ericsson in order to achieve our goals.”

Arun Bansal, Head of Europe and Latin America, Ericsson, says: “We are working with Vodafone UK to evolve its 4G network and test new 5G technologies. Together we will enable ubiquitous connectivity for their users that enable entirely new experiences, as well as monitoring and control of IoT in real time.”

Ericsson and Vodafone have also signed a memorandum of understanding that will cover the following areas of collaboration:

  • 4G evolution, 5G radio non-standalone and standalone;
  • 5G site deployment scenarios;
  • NR simulations: 3.5 GHz and mmWave;
  • 5G use-cases: business case study and proof of concept;
  • distributed cloud and network slicing proof of concept: end-to-end latency and cloud- optimized network applications;
  • collaboration with King’s College London; and
  • 5G innovation: Technology Incubation Programme.

Vodafone and Huawei Trial New 4.5G Technologies to Prepare for 5G

Vodafone and Huawei Trial New 4.5G Technologies to Prepare for 5G

 Vodafone UK and Huawei are conducting technical trials of a new mobile technology, 4.5G (TDD+) with LTE TDD, to significantly increase the capacity and efficiency of its 4G network in urban areas, as well as lay the foundations for the introduction of 5G by 2020.

New 4*4 MIMO (Multiple-Input Multiple-Output) techniques eight-way transmit and receive (8T8R), together with multi-user beam-forming are being tested in Manchester. These will support the expected rapid growth in video and virtual reality applications with the arrival of next generation smartphones.

Unlike traditional methods of transmitting mobile signals between base stations and mobiles, beam forming and four-way receiver diversity significantly improve performance in heavily built up areas, by combining the signals from multiple angles and co-located antennas in order to reduce interference and improve throughput. The trial involves 4×4 versions of MIMO in order to deliver mobile data services at much greater speeds and with improved accuracy. The 8T8R beamforming concentrates the user-specific energy and multiplexes the resource between different users, thus increasing the average as well as the edge performance.

By combining MIMO with beam-forming, Vodafone is better able to focus customers’ mobile signals in specific directions to ensure the best user experience and minimise interference during peak times in highly populated areas. As a result, more signal reaches more subscribers particularly at the edge of the base station coverage, in order to provide higher average speeds across the network.

Vodafone UK’s Chief Technology Officer, Jorge Fernandes, said: “We are working hard with our radio network equipment partners to ensure our network is future-proofed for the expected arrival of 5G in four to five years’ time, whilst continually improving our 4G performance for customers throughout the UK.”

Huawei LTE TDD President, Veni Shone, said: “This joint innovation with Vodafone has proved that 4.5G (TDD+) is a good solution to release the potential of TDD spectrum and will help Vodafone build the most advanced LTE network available. We are very proud of this collaboration, and are dedicated to providing optimal solutions to customers. The newly deployed LTE TDD network immediately serves the LTE TDD capable commercial smartphones and successfully carries significant live network traffic. This trial proves that LTE TDD with the most recent technologies can be naturally converged with LTE FDD and improve the overall experience enjoyed by all users on the network.”
