Success Stories
UK Glasgow Ibrox Stadium Wi-Fi Project Background
Ibrox Stadium is a football stadium located on the south side of the River Clyde in the Ibrox district of Glasgow. Ibrox is best known for being the home ground of Rangers FC. Ibrox is the third largest football stadium in Scotland, having an all-seated capacity of 51,082. More and more people are using smart devices as a primary means of communication, and the Rangers club looks forward to revolutionizing the way in which Rangers fans can engage with the club before, during and after the match.
Requirements
Rangers Football Club aims to provide the supporters with a world-class Wi-Fi service to enhance their match-day experience. The network will give the 50,000+ fans, as well as those in the approaches, concourse, restaurants and corporate areas, full access to content rich media as well as access to club competitions, merchandising, team talk discussions and forthcoming events. Being capable of supporting VoIP by the wireless infrastructure is required.
UK Glasgow Ibrox Stadium Wi-Fi Project Huawei Solution
Advanced RRM features and narrow beam bandwidth antenna design reduces co-channel interference and improves user experience; Professional network planning maximizes network capacity with fewer interference; Wired and wireless integration builds high efficient and secure network, AC redundancy and hot-standby to ensure the business high reliability; Leading industrial design of access point improves resistance to harsh environment such as lighting, water and high/low temperature;

WLAN Project for Jiading Stadium in Shanghai Background and Requirements
A WLAN network needs to be constructed to provide wireless coverage for Jiading Stadium in Shanghai. As the breakthrough point for Jiading's "Smart City" plan, this project will realize Wi-Fi coverage for Jiading F1 autodrome, including the stand, VIP rooms, garage, and commercial center, and must meet requirements of subsequent large sporting events. Therefore, the WLAN network must be reliable enough to support access of high-density users in areas such as the stand and square.

Huawei Solution
Huawei organized a professional network planning team, designed and deployed the network through comprehensive site surveys and industry-leading planning tools, which addresses the problems such as coverage holes, unstable signals, and wireless interferences of the original network. Huawei solution supports IP67 protection standards and uses enhanced outdoor APs to ensure equipment-level and network-level reliabilities. Huawei provides a high-performance and reliable wireless network through advanced technologies, such as service endurance, intelligent load balancing, auto-sensing user scheduling, Layer 2 isolation, and anti-interference.
Customer Benefits
Audiences can enjoy a reliable and stable wireless access in high user density areas such as the stand and square, which ensures an excellent service experience.
