PicoCELA system has been deployed as an ad-hoc Wi-Fi network for trade shows in large venues. On average, these trade shows host over 100,000 visitors over 3 days. The network is set up as the booths go up (5 min per access point including attaching to the booths), and are taken down once the show is done (3 min per AP). Roughly 120 AP’s (with 12 core nodes) are used for the system.
