I need a little advice about setting up a wireless network for a community aquatic center. The facility is about 100 meters by 45 meters, and during a big event there could be over 200 clients connecting at once. Right now we have a personal wireless router that cannot handle the load and doesn’t have a good range. With this being in a pool there is also high humidity. I would like to create a network that has one secure SSID as well as a guest network. I have been looking into at using access points as repeaters to extend the signal. I have also been looking at the Ubiquiti UniFi AP-PRO line. If anyone could provide me with some help or a better method I would really appreciate it.
