Companies Demonstrate LTE Approach that could Increase Network Capacity

Wireless-services provider NTT DoCoMo and telecommunications equipment and services vendor Huawei Technologies have shown that they can deploy Long-Term Evolution (LTE) wireless technology in the 5-GHz frequency band, which would let mobile carriers enlarge their network capacity.  The NTT DoCoMo-Huawei test found that LTE can achieve speeds of up to 100 Mbits per second in the frequency band, which is currently used for Wi-Fi networks. It also showed that Licensed-Assisted Access (LAA), which allows LTE to operate in unlicensed bands and allows operators to offload data when traffic congestion occurs in hotspots, can be used to enhance both LTE and LTE-Advanced wireless networks. The companies say these technologies enable operators to expand their networks during busy periods while still providing “the benefits of guaranteed security, coverage, mobility, and unified quality of service.”  DoCoMo and Huawei have yet to announce commercialization plans for their approach.

Ericsson Demonstrates 5G Wireless Technology

Ericsson has succeeded in demonstrating a prestandardization version of 5G wireless technology operating in the 15-GHz frequency band. The trial used a new radio interface and advanced multiple input, multiple output (MIMO) technology, which utilizes multiple transmitter and receiver antennas to increase bandwidth. Ericsson is also working on wider-bandwidth radios that can operate at higher frequencies with shorter transmission times and new base stations. The technology is not expected to be commercially available until 2020. However, Ericsson says proving the technology’s performance in a trial test is important for the technology to progress. The company conducted its tests at its lab in Kista, Sweden, witnessed by senior management from Japan’s NTT DoCoMo and South Korea’s SK Telecom, which have also been conducting 5G trials. Industry observers say higher-performance mobile technologies are needed to satisfy demand by customers and by approaches such as machine-to-machine technology. They add that mobile-equipment vendors like Ericsson want to demonstrate 5G’s potential to begin creating a demand. (PhysOrg)(Ericsson)

UK, Germany Collaborating on 5G Technology

UK Prime Minister David Cameron says his country is working with Germany to develop 5G cellular technology. Researchers from Dresden University, King’s College London, and the University of Surrey are collaborating on the initiative, designed to provide a wireless approach that is substantially faster than today’s 4G technology. This is one of three research areas designed to improve European telecommunications and advance the Internet of Things that Cameron has identified. The UK is offering £73 million in research funding for the latter. (SlashDot)(ZD Net)

UK Funds 5G Mobile Research

Mobile operators, infrastructure providers, and the UK Research Partnership Investment Fund have given the University of Surrey £35 million (about $56 million) to create a 5G Innovation Centre and develop energy-efficient, affordable fifth-generation wireless technologies that would be available commercially by 2020. Standards organizations haven’t defined 5G yet, but it is expected to yield speeds of up to 200 Mbps. Private companies contributing to the research include Huawei, Samsung, and Telefónica Europe.
