We are photographers working with wireless cameras sending files about 0.5mb about 1200 a day, out on mobile locations such as shopping malls, sporting events etc.
Our equipment uses b & g, and need to send images over distances 200-800 (sometimes more) meters around corners, upstairs, through glass. Now the killer!! need to connect to the internet (hot Spots) as well, with the computers on our own network as well as the hot spot in case the wireless network is not possible then we would connect to the hot spot and upload images and download images using FTP. for example:-
Point A= Photographer uses B, G wirless to send images to netbook close by with access point? connected to 5ghz configured as client.
Point B= 5ghz configured as access point to get round corners, glass, stairs etc
Point C = receiving computer, 5ghz configured as client to receive images
Point a and b also need to access hot spot at the same time just in case the wireless networks stops working.
Hope I explained this well enough wish I could add more than 500 points!!!!!
