KDDI and Samsung prove 5G mmWave works at 190 kmh

KDDI and Samsung Electronics completed a series of 5G tests which demonstrate the viability and performance of 5G millimeter wave mobility solutions while traveling at speeds over 190km per hour.

The demonstration, which took place at 'Everland SPEEDWAY' in Korea, involved a battery of individual tests to examine the performance of Samsung's end-to-end 5G mmWave technology. Specifically, as a vehicle accelerated from 0 to 205km per hour on the race track between multiple 5G base stations, the test measured and evaluated a variety of metrics, including handover interruption time, uplink and downlink throughput stability, and latency stability (or "jitter").

In addition, KDDI and Samsung also demonstrated a successful handover scenario, with Samsung's 5G device attaching to the 5G base station as it approached the service area, and successfully being handed over to the target cell at a speed of 192km per hour (GPS speed).

Woojune Kim, Senior Vice President and Head of Next Generation Strategy in Network Business at Samsung Electronics, said, "It is becoming increasingly important that we accelerate our focus on 5G's ability to meet a growing number of performance metrics. Until now, peak bandwidth has been the common refrain, and certainly a big component of the future of 5G. However, the test we conducted with KDDI will help us build a more diverse portfolio of future 5G use cases."

"The trial successfully showcased stable performance under high-speed mobility conditions which will dramatically increase the service experience of users in vehicles," said Akira Matsunaga, Senior Director, Mobile Network Technical Development at KDDI. "We will continue our joint efforts with Samsung to test next generation technology to unprecedented levels and discover new service cases."

Teraphysics Raises $50 Million for mmWave Technology

Investment firm Boustead Securities has announced that Teraphysics, based on Cleveland, a developer of high-speed wireless transmission technology, has received SEC qualification for a $50 million capital raise through the issuance of Regulation A+ securities.

In conjunction with the announcement of its Regulation A+ securities issue, which is underwritten by Boustead, Teraphysics also recently detailed its commercialisation plans for the mmLink technology.

Under the terms of the transaction, Teraphysics is issuing 10 million share of common stock at $5 per share. The net proceeds will be used to fund the commercialisation phase of its technology, including the development of a micro link wireless network for the demonstration of wireless terrestrial and stratospheric platforms, the establishment of a piloting facility and the purchase of production capacity.

Teraphysics, founded by three former NASA scientists, has developed mmLink technology that enables high-speed data transmission and targets applications for next generation 5G mobile data connectivity and Internet access. Development of the company's mmLink millimetre-wave amplifiers was supported with funding from the NASA Jet Propulsion Lab, Air Force Research Lab and the Defense Advanced Research Projects Agency.

Based in Cleveland, Ohio, Teraphysics was founded by Louis S. Fisi and scientists Dr. Gerald T. Mearini (PhD) and James A. Dayton,, Jr. (PhD). The company has developed patented devices designed to significantly enhance 5G data delivery. Teraphysics' IP includes its patented and commercially viable THz source that employs miniaturised vacuum electronics.

The mmLink solution is a wireless solution able to transmit at very high data rates using a millimetre-wave amplifier that has been developed from technology installed in NASA vehicles including the Mars Observer and Cassini spacecraft.

The Teraphysics amplifier is designed to provide high power and wide bandwidth in previously inaccessible parts of the millimetre-wave band and is intended to offer a lower cost, quicker to install alternative to fibre connectivity. The company's first amplifier is expected to deliver data rates of 10 to 20 Gbit/s, while future products could support rates of up to 150 Gbit/s.
