My rule of thumb is “30-40 clients per radio”. In otherwords, when I get to 30, I start planning for transitioning from omnidirectional to multiple sectors for the site and implement it when the site gets above 35 clients on the omni.
If you have lower bandwidth profiles and no p2p abusers, you could probably get away with 50 users with a profile like 512k/128k; but I wouldn’t recommend it.
OK, many thx This routerboard will be using for the OLPC laptops, witch means that the laptops will really have little access to Internet, they may be used to connect to a file server.
