I’m looking for an idea of what qualities to look for in the equipment for a wireless network that covers the entire area of an outdoor arena. The area is rectangular-ish in shape. 400ft wide and 600ft long. It has 6 light towers, 1 on each of the 400 foot ends and 2 on each of the 600 foot ends. I can mount on anything and spend as much money as needed.
The needs of the network would be to provide access for, up to 15 wireless HD cameras with audio, and a public-wifi network. Can someone point me in the right direction as far as figuring out what information is critical for setting up a wireless network with many users having different needs in a small space?
Make sure your private network equipment is on 802.11a/n (5Ghz band). That provides more channels and less native interference, so you’ll find more reliability.
Work with directional antennas and reduce access point transmission power. The directional antennas will reduce noise from other areas. The more isolated cells you can get, the more clients you can handle.
If you can make sure that your power is such that your APs aren’t stomping all over each other and that your APs don’t listen to areas they can’t respond to (a stronger signal from an undesired area), then the last catch will be the omnidirectional user devices… and those will just have to play nice or figure it out.
While traditional wisdom is to use fully non-overlapping channels, do remember that some overlap may be a beneficial sacrifice for being able to get more adjacent cells. The Wifi spec demands that the further you get away from the center channel, the lower the signal strength becomes. Thus, while channels 1 and 6 dont overlap at all, adding an AP using the space of 3 or 4 will do less harm than using 2 or 5 and in a high-interference environment may work to increase overall bandwidth.
Generally, there’s benefit in more expensive controllers and also in controllers that run multiple radios from a single unit. When laying out your network, you’ll get a big boost in positioning things if you can turn on just a few radios at a time and map their coverage, then test with everything online at once.
Since you’ve got a hefty budget, consider hiring a consultant who has previously worked on conference wireless deployments. This is one of those areas where most of the work needs to be done beforehand and can’t be really be fixed during an event if it wasn’t right the first time.
