[QUOTE="Chad Young, post: 49678, member: 699"] Re: Large scale concert production TCP/IP networking A very good question. If I were forced to use 802.11a/b/g/n, I would use a quality wireless router (Cisco 800 series is a fave of mine), WPA2-PSK (only because most non-computer devices have trouble using certificate-based authentication), probably turn off SSID to limit exposure a bit, and keep it all as one closed loop with no internet access. A little trick you can do with some routers is to set up a secondary SSID and brodcast it, but make it a complete dead-end. Your casual hacker will usually go for the easy decoy target and ignore the 'hidden' one. For a more serious or mission critical application, fiber-optics is awesome, the microwave link you indicated would be very nice, as would Free Space Optics. Free space optics, in particular, have great bandwidth, excellent range, and are quite secure, but not too many are geared for mobile use. Provided you are not intentionally 'jamming' anything, this is an excellent approach. I have seen similar, but these bear looking into. I have a situation here where one of those might be rather useful. Our folks have this habit of selecting and outfitting buildings and then, after the fact, coming to use for data connectivity.
