TOKYO, Jan 28, 2021 - (JCN Newswire) - NTT DOCOMO, INC. and East Japan Railway Company (JR East) jointly announced that they have verified the stable operation of important 5G communication capabilities, including handover between base stations and the transmission of high-definition video data, in trials conducted aboard JR East s ALFA-X(1) Shinkansen test train running at 360km/h. The trials confirmed that it will be possible to ensure stable mobile communication environments on high-speed trains for the delivery of high-value mobile services.
DOCOMO has been working to confirm the feasibility of 5G communication in high-speed environments since 2017. For the newly announced trials, experimental equipment conforming to international standard and specifications established by the 3rd Generation Partnership Project (3GPP(2)) was put through various trials conducted for the first time in Japan aboard ALFA-X running at 360km/h.
IMTS mobile phone (Motorola)
There has been a tremendous development in the telecommunication industry over the past 80 years. Many smartphone enthusiasts of today do not really know how far the industry has developed. This is why we put together this interesting article to look at the development of the telecommunication industry since the second world war.

Apple sued for alleged infringement of wireless communications patents
News Highlights: Apple sued for alleged infringement of wireless communications patents
Apple has been hit by a lawsuit alleging that the iPhone and other mobile products infringe a handful of wireless patents.
The complaint, which was filed Wednesday in the US District Court for the Western District of Texas, alleges that Apple knowingly infringes five pieces of intellectual property owned by Delaware-based Neo Wireless, LLC.
Those patents target some of the underlying systems related to wireless communications, frequency bands and other cellular technologies. First submitted between 2005 and 2004 by inventor Xiaodong Li and other co-inventors, they cover parts of the technology related to LTE standards completed under the 3rd Generation Partnership Project – a group of standards organizations developing telecom protocols.
Report: Ban on Chinese vendors will delay global 5G rollout by several years
Share on email
Banning Chinese vendors from Western countries’ 5G deployments on the grounds of alleged equipment security concerns will have a detrimental effect on 5G rollouts and technology evolution for the years to come.
According to new research by analyst firm ABI Research, excluding Huawei from deployments will delay the 5G rollout by several years and burden network operators with additional costs of several billion dollars to replace existing infrastructure.
“Our research shows that banning Huawei and ZTE from 5G deployments and restricting their access to silicon and semiconductor supply chains will have severe implications on economic performances. Furthermore, banning these Chinese vendors will hamper 5G and 6G R&D,” said Leo Gergs, research analyst for 5G markets at ABI Research.
