Background 

Beijing Bird's Nest Stadium, located in the southern part of the central area of Beijing Olympic Park, was the main  stadium of the 2008 Beijing Olympic Games. It covers an area of 204,000 square meters, with a construction area of  258,000 square meters. The stadium can accommodate 91,000 audiences.

Challenge 

• Solve the problem of blind zones of signal coverage.

• Huge call volume and limited channel resources.

• Strong anti-interference ability is required.

• Improve work efficiency and ensure safe operations.

• Empower the staff and volunteers with reliable and  convenient communication supports.

Solution 

According to the comms needs of the Bird's Nest, Kirisun adopts the advanced DS6000 digital trunking system to build a set of 8-carrier base stations, including 15 shared channels, 1 center node switch, 1 recording server, 1 dispatching  server, 2 dispatching clients, and 400 DP990 portable radios. 

In addition, we have also deployed 1 optical fiber transceiver and a n indoor antenna feeder in the venue office to  eliminate the shielding of radio signals in the steel-concrete building.
