Huawei and Beijing Jiaotong University completed vehicle-to-ground communication test: 350km / h with bandwidth close to 1Gbps

Thanks to CTOnews.com netizens drifting, Huake high achiever's clue delivery! CTOnews.com April 27 news, recently, Beijing Jiaotong University "Rail Transit Operation Control system National Engineering Research Center" released the "Huawei WLAN system high-speed scene laboratory test report". According to the report, Huawei and the Rail Transit Engineering Center of Beijing Jiaotong University jointly completed the test of the urban rail service carrying capacity of the Wi-Fi 6 communication system in the 350km/h high-speed mobile scene. The test results show that the bandwidth of the train running 350km/h reaches 980Mbps, which is close to 1Gbps. (CTOnews.com Note: 1 gigabit per second).

According to the report, in order to verify the availability of Huawei's Wi-Fi 6 network in high-speed mobile scenarios, the Rail Transit Engineering Center of Beijing Jiaotong University adopts the product portfolio of Huawei AirEngine X760R-XXE trackside AP and AirEngine 6760-51EI on-board AP at 120km/h, 160km/h, 200km/h, 260km/h and 350km/h speeds, respectively. The carrying capacity of Huawei urban rail Wi-Fi 6 network to train passenger information system (PIS) and video service is tested.

In the Development Plan of Modern Comprehensive Transportation system in the 14th five-year Plan, the state clearly requires that "strengthen the inter-city traffic construction of key urban agglomerations, promote the integration of inter-city railways and urban rail transit, and reasonably promote the cross-line operation of rail transit". Under the support of industrial demand and policies, rail transit has been able to develop at a high speed, with the highest operating speed of 160km/h and the highest design speed of 200km / h; at the same time, rail transit has gradually entered the "era of fully automatic operation". The high-speed movement and automatic operation of rail transit and the real-time return of business data such as train passenger information system (PIS), on-board video, pantograph and catenary detection system put forward new challenges and requirements to the train-to-ground wireless communication system.

Huawei said that its Wi-Fi 6 network solution for smart urban rail cars provides "high performance, fast switching and easy deployment" Wi-Fi 6 communications for high-speed trains through a variety of technological innovations such as hardware and algorithms.
