[QUOTE="Jon Malmstrom, post: 76485, member: 2464"] re: X32 - XControl, Routers and WiFi [B]Multiple networking - Wifi, wireless and so on #edit 1 - some typo´s and comments from Rob Timmerman [/B]I want to share my thoughts about wifi frequency planning etc when setting up wireless access on venues, related to the earlier discussions here and in the X32 thread. As the x-family now officially evolves with more network based products i think it is necessary to share facts, information and experience to each eachother! Using wifi to run shows and mix remotely is wonderful, but some care must be taken into planning in my opinion in order to set up a robust and reliable network infrastructure with the highest possible availability. Please add info and comment. Correct me if i have stated something wrong! Cheers, Jon [U]Frequency Spectrum [/U] Some useful input and facts about the wifi standard can be found here [URL="http://en.wikipedia.org/wiki/IEEE_802.11"]IEEE 802.11 - Wikipedia, the free encyclopedia[/URL] The 2.4 GHz ISM band is very crowded by: - Wifi devices in 802.11 B/G mode - access points, mobile phones with internet sharing/tethering/personal hotspots. - Bluetooth devices - Wireless microphones - Line 6 - Other wireless products, remote controls etc that not use the 400/800 MHz band. One example is R/C aircrafts/Heli´s that recently have moved up to the 2.4 ISM band. - Electromagnetic Interference from Microwave owens The relatively new 802.11 N-standard is using both the 2.4 and 5 GHz band. Some devices can be run exclusively in 802.11 A - 5 GHz mode which for now is less crowded. It provides higher data rates (due to wider bandwith/channels). Range and penetration in buildings is less than the B/G standard, but can be handled with external antennas. For more information on the N-standard, see [URL="http://en.wikipedia.org/wiki/IEEE_802.11n-2009"]IEEE 802.11n-2009 - Wikipedia, the free encyclopedia[/URL] This facts conclude that: [LEFT][COLOR=#000000][FONT=Verdana]2.4GHz: + compatible with almost everything + goes through walls better than 5GHz - fewer non-overlapping channels - more likely to be congested [/FONT][/COLOR] [COLOR=#000000][FONT=Verdana]5GHz: + more non-overlapping channels + less likely to be congested + usually faster than 2.4GHz - more likely to be blocked by walls - fewer compatible devices[/FONT][/COLOR][/LEFT] -the 5 GHz band should be preferred for a FoH wireless network to avoid interference with potential hostile emitters on 2.4 GHz. -not all devices can use the A/N-mode in 5GHz only.
