Having been fouded for nearly 18 years , the number of employees has risen from dozens to 60,000 today.The 2017 annualparty was Ali's adult ceremony so the scale was unusual. On September 8th , the biggest annual party of Alibaba was held in Hangzhou Huanglong Sports Center which covers an area of 620,000 square meters ,more than two-thirds of employees attended the 18th anniversary.

Requirements and Challenges
The annual party was held in the Hangzhou Huanglong Sports Center, which is known to be used for cocerts and soccer games .What we have to do is making every corner of the venue get wireless signals so that the 40,000 people can surf the Internet steadily and achieve full coverage of wireless network.
The project was a huge challenge for no one having achieve a similar wifi coverage before.There are several aspects :
-How to effectively reduce the signal interference between the base stations while satisfying the 600,000 square coverage.
-The total number is up to 40,000，how to guarantee the load balance of each base station.
-Installation trouble, how to ensure that the coverage of each device is not overlapping.
-How to increase the maximum number of base station access for a number of people.
The AP is specially designed for Ali's annual party, and we modified the antenna to make it narrower.The maximum access to each WCAP-AC-D can reach up to 120, which meets the demand of the Internet at the same time, and the wireless rate is as high as 1200Mbps.As an outdoor AP, WCAP-AC-D is also equipped with waterproof and lightning protection.For details, please visit our website.
|First，according to the seat distribution on the scene, we deployed the two floors above and below.Then the distance between AP was planned according to the number of users connected to each individual AP.Finally, in order to complete the deployment as soon as possible,we adopted a flexible approach of Installing AP on the guardrail which makes signal cover from bottom to top.|
Achivements and Comments
The site network is the same as Ali's normal office network which makes everyone present a strong sense of belonging just like in the office.The wireless network provided by devices together with the 4G networks supported network needs of 40,000 people in the party.However, wireless networks performed better than 4G, almost all staff used the wifi to post feelings or videos on social networks.
-I'm glad I made a right choice (wis). The solution and the guidance of the site layout they provided helped us successfully host the annual party which gained the high praise from leaders and the whole staff.
-I had thought that the mobile phone signal would be bad for my seat was far behind ,but wis surprised us and the Internet experience was pretty good. So we have been sharing videos and pictures with the family, and I am looking forward to their ability to provide better equipment for our future activities.
