Over 18,000 ㎡tech zones……. Over 20,000 participants…… Over 53,000 access users…… 6.8 TB total data traffic……
These data came from 796 Wi-Fi hotspots deployed at HUAWEI CONNECT 2016. Thanks to these hotspots, guests were able to share pictures using Wi-Fi throughout the entire site and watch keynote speeches through full high definition (HD) network broadcast, enriching overall visit experience. The smooth Wi-Fi experience made a big impact, with guests continuously providing positive feedback and even requesting to buy the Wi-Fi deployment solution.
What is the deployment story behind this highly appraised Wi-Fi network?
Three Venues, Different Deployment Needs
Huawei Provides Flexible Solutions to Adapt to the Needs
Shanghai World Expo Exhibition & Convention Center (SWEECC)
11,000 m² of open space, equivalent to one and a half soccer fields. The ceiling is 6 to 8 meters high, and does not allow for AP installation on it, putting forward a huge challenge for Wi-Fi deployment and AP installation.
Based on the environment, Huawei installed APs on the four sides around load-bearing pillars and on walls. The AP8130DNs and 30° directional antennas are used. The antennas were installed at a height of 5 meters above the ground according to the distance between the pillars, and used non-overlapping channels, minimizing signal interference.
Shanghai Expo Centre
7,500 m² hall without columns and a 15-meter high ceiling. Traditional APs with omnidirectional antennas provide scattered signal coverage. The higher the installation, the weaker the signal is at the bottom. Additionally, in a structure with such a high ceiling as the Shanghai Expo Centre, signals are more likely to spread everywhere, causing severe interference between APs.
APs and directional antennas were installed on the catwalks above the booths, solving traditional solutions’ signal coverage problems. The catwalk was 15 meters high and used 30° directional antennas for signal coverage. The antennas were installed at an interval of 10 meters. The exhibition booths were distributed all around the hall. By adjusting the antennas’ azimuth and downtilt angles, signal quality was at its best in the areas close to the exhibition booths.
With 18,000 seats, it is the only stadium that can be compared to Beijing’s Wukesong Culture & Sports Center within China. Such large venues have common characteristics: multilayer stands, high user density, and over 200 users per 100 m² at a full house. If APs are deployed sparsely, the network cannot provide sufficient capacity, with some users being unable to connect; if APs are deployed too closely, channel interference will occur.
Huawei engineers directly installed AP8130DNs and 15° directional antennas on the edges of each layer of stands using 2.4-meter high T-bars, with one AP every 4 meters. It was ensured that there was no coverage in the arc area by properly adjusting the antennas’ azimuth and downtilt angles. In order to guarantee the entire network’s capacity, Huawei used AP8130DNs that support software-defined radio (SDR) technology, allowing for flexible switching from 2.4 GHz to 5 GHz radios. The 2.4 GHz and 5 GHz radios were deployed on a ratio of 1:7 at the site, achieving the best user experience possible.
By using customized solutions and products, Huawei built a high-experience Wi-Fi network for attendees. The smooth Wi-Fi experience and high appraisal validate the excellence and outstanding performance of Huawei’s High-Density Wi-Fi Solution.
