On August 4, China Tower and Huawei Applied sciences Co., Ltd. formally unveiled a brand new tunnel waveguide product: TunnelStar on the China Tower Industrial Park. Tailor-made for high-value tunnel situations, the modern resolution options compact measurement, decrease prices and superior person expertise, injecting new momentum into community high quality enchancment and model worth enhancement for telecom operators.
Senior executives from China Tower and Huawei Applied sciences Co., Ltd. attended the launch ceremony.
In accordance with the officers current, China’s rail transit tunnel scale has maintained regular progress, with the nationwide operational subway mileage exceeding 10,000 kilometers and the mileage of operational railway tunnels surpassing 25,000 kilometers. Tunnel situations have lengthy been suffering from trade ache factors, together with restricted set up area, complicated on-site development situations and tough renovation coordination. In the meantime, as cell communication networks speed up the iteration towards 5G-A, communication frequency bands and spectrum bandwidth proceed to broaden. Pushed by booming purposes reminiscent of AI and reside streaming, person demand for uplink companies retains rising, highlighting the weaknesses of uplink protection and placing ahead extra stringent technical necessities for tunnel indoor distribution and sign protection techniques.
In opposition to this backdrop, China Tower and Huawei have carried out in-depth technical cooperation. Combining the propagation traits of radio waves in tunnels, the 2 events have collectively developed the TunnelStar, breaking via the technical bottlenecks proscribing tunnel community protection. Geared up with a specifically designed excitation supply to reshape electromagnetic subject distribution, the product allows extra uniform wi-fi sign protection in tunnels and maximizes general protection efficiency.
In contrast with conventional antenna options, the modern TunnelStar boosts edge protection stage by greater than 10dB and improves person expertise velocity by over 40%. It helps a 9dB achieve amplification for uplink hyperlinks, delivering a 20% improve in uplink velocity to fulfill the demand for high-capacity uplink information companies. As well as, the product helps low-cost evolution towards 6G, enabling easy transition for brand new frequency band purposes. As a full-band and full-bandwidth resolution, it empowers China Tower to leverage its unified planning and development benefits, serving to telecom operators clear up key trade challenges together with high-capacity uplink and high-frequency community evolution in tunnels, tough leaky cable development and poor antenna protection results.
The TunnelStar resolution has accomplished pilot checks for 3.5G and 4.9G frequency bands in Wuhan and Guangzhou respectively. The check outcomes present vital enhancements in protection efficiency and deployment effectivity, that are extremely in keeping with the design targets.
TunnelStar blazes a brand new path for upgrading tunnel community expertise. It successfully breaks the protection bottlenecks in excessive tunnel situations, tremendously bettering person expertise and satisfaction, and setting a benchmark for final cell community protection.
Wanting forward, the 2 sides will additional combine China Tower’s benefits in built-in general planning, co-construction and undertaking implementation with Huawei’s cutting-edge communication R&D capabilities. Each events will proceed to iterate and improve collection of in-depth tunnel protection applied sciences and options, comprehensively optimize the digital journey expertise for the general public, and empower a greater digital life for all.
