Softbank implements Machine Learning in the RAN with Ericsson

SoftBank is using machine-learning software developed by Ericsson for advanced radio network design in the Tokai region. The service groups cells in clusters and takes statistics from cell overlapping and potential to use carrier aggregation between cells into account, thus reducing operational expenditure and improving network performance. The machine learning evaluates cell coverage overlap, signal strength and receive diversity. Big data analytics was applied to a cluster of 2000 radio cells and data was analyzed for the optimal configuration.

Ericsson’s centralized and elastic radio access network design is sold as a service and supports LTE networks. Ericsson says that compared to traditional network design methods, the ML approach cuts the lead time by 40 percent.

Ryo Manda, Radio Technology Section Manager at the Tokai Network Technology Department of SoftBank, says: “We applied Ericsson’s service on dense urban clusters with multi-band complexity in the Tokai region. The positive outcome exceeded our expectations and we are currently proceeding in other geographical areas with the same method and close cooperation with Ericsson.”

Peter Laurin, Head of Managed Services at Ericsson, says: “There is a huge potential for machine learning in the telecom industry and we have made significant investments in this technology. It is very exciting to see that the new methods have been successfully applied in SoftBank’s network. There is a strong demand for this type of solutions and deployments of this service to other tier-one operators in other regions are ongoing.”

NTT employs Orbital Angular Momentum multiplexing for 100G wireless

NTT successfully demonstrated the first use of Orbital Angular Momentum (OAM) multiplexing to achieve 100 Gbps wireless transmission.

The laboratory tests combined OAM multiplexing with Multiple-Input Multiple-Output (MIMO) technology and carried the signals a distance of 10m.

NTT said a key feature of OAM is that electromagnetic waves can be superposed and separated because phase rotation occurs on the vertical plane in the propagation direction.  An electromagnetic wave with phase rotation cannot be received without a receiver having the same number of phase rotations at the time of transmission. NTT developed a transceiver operating in the 28 GHz band capable of OAM transmission. NTT also developed signal processing technology capable of handling 11 data signals simultaneously each at a bit rate of 7.2 to 10.8 Gbps, thereby achieving large-capacity wireless transmission at a total bit rate of 100 Gbps.

NTT believes the technology holds promise for achieving large-capacity wireless transmission at a level about 100 times that of LTE and Wi-Fi and about 5 times that of 5G.

NEC announces agreement to supply 5G base stations to NTT DOCOMO

NEC announced an agreement to supply 5G base station equipment to NTT DOCOMO. Financial terms were not disclosed. Docomo aims to launch 5G in 2020.

Under this new agreement, NEC will achieve 5G compatibility through software upgrades and a minimal replacement of hardware to maximize the use of existing high-density base station equipment.  NEC said it will provide updates that enable existing high-density base stations to be fully compatible with 5G while continuing to deliver LTE/LTE-Advanced services.

This includes base station equipment that NEC has been supply to DOCOMO since February 2015. This equipment is already compatible with the advanced Centralized Radio Access Network (C-RAN) architecture advocated by
DOCOMO, and is now being utilized as a base station control unit.

"DOCOMO aims to deploy and expand our commercial 5G services efficiently by maximizing the use of existing communications equipment," said, Hiroshi Nakamura, Executive Vice President, Chief Technology Officer and Member of the Board of Directors, NTT DOCOMO. " This agreement with NEC is in line with that policy and we expect it to make a significant contribution to our 5G services. Going forward, DOCOMO accelerates co-creation of new services and businesses with vertical industry partners."

NTT Docomo and NEC test 5G to race car traveling at 300 km/h

NTT DOCOMO and NEC conducted a test of 5G connectivity to a race car moving at 305 km/h (190 mph)

The test, which used 28 GHz spectrum, sustained a downlink of 1.1 Gbps between the 5G base station and the 5G modem in the car moving at 293 km/h and a fast handover during communication between 5G base stations and a 5G mobile station moving at 290 km/h. In addition, the trial succeeded in a wireless live relay of 4K high-frame-rate video via uplink from a 5G mobile station moving at 200 km/h. Both the 5G base station and 5G mobile station in the car were equipped for beamforming, which concentrated radio power in a specific direction, and beam tracking, which switched the direction of the beams to follow the 5G mobile station as it moved at high speed.

The trials were conducted last month at the Japan Automobile Research Institute (JARI).

The 4K video transmission operated at 120-frames-per-second and used NTT's real-time 4K high-frame-rate HEVC codec.

Other companies involved in the trials included DOCOMO 5G Open Partner Program participants, Sony Business Solutions Corporation, and DOCOMO TEAM DANDELION RACING manager Dandelion Limited.

NTT demos its photonic crystal fiber with high-powered lasers

NTT and Mitsubishi Heavy Industries (MHI) have demonstrated a kW class, high-power single-mode laser transmission over tens to hundreds of meters --
representing a breakthrough for laser processing technology.

The innovation leverages NTT's photonic crystal fibers (PCF) and MHI's high power laser processing technology.

NTT's photonic crystal fiber transmits light by using the confinement effect of air holes. PCF consists of silica glass and multiple air holes, and offers novel properties impossible with conventional optical fiber.

Laser processing requires the transmission of light whose power is more than 10,000 times that of conventional telecommunication light. However, maximizing the optical power and transmission distance encounters the physical limit created by optical nonlinearity. Applications include a range of infrastructure products, including in transportation, manufacturing, and precision cutting.

The achievement will be reported at the 89th lecture of Japan Laser Processing Society, which will be held at Suita Campus, Osaka University at 23-24 May 2018.

Nokia and KDDI test 4G LTE connected vehicles in Japan

Nokia and KDDI have conducted a series of tests in Japan to assess the use of 4G LTE for low-latency connectivity for vehicles.

For the proof-of-concept trials in Japan, Nokia and KDDI focused on vehicle to network use case and used non-integrated systems in cars interacting with sensors via the Nokia Multi-access Edge Computing (MEC) platform, which enables significantly reduced network latency.

The testing included LTE broadcast, implementing the evolved Multimedia Broadcast Multicast Service standard in two connected car applications, and demonstrating the potential of cellular technology to enable fully automated driving in the future.

Nokia said its evolved Multimedia Broadcast Multicast service (eMBMS) hotspot solution allowed real-time information to be shared with multiple vehicles to enable awareness and road safety. The companies compared the efficiency of using LTE broadcast to the one-to-one communication enabled by LTE unicast, in two connected car applications:


  • Vehicle-to-network-to-vehicle (V2N2V) - in which cars maintained constant contact with the MEC system, sending real-time location, direction and speed data to roadside sensors. In an emergency situation, the driver can alert the application, with information distributed to other vehicles using eMBMS.
  • Network Real-Time Kinematic (network RTK) -trial of LTE to enhance fully automated in-vehicle navigation. It showed how eMBMS could more cost-efficiently use existing geo-location systems to communicate to many vehicles in real-time and ensure accurate navigation.

The trials were conducted by Nokia and KDDI at a rural location on the Japanese island of Hokkaido.
