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!!!!!

5Ghz sounds good, only a few concerns with the things you have mentioned...

1. Wireless could be slow if your transferring that many photo's!
2. Most hotspots only do 2.4Ghz B - not G
3. When your equipment needs to connect to hotspots, do you mean your camera's or laptops? as some hotspots require you to go to a web page before accesing the internet - which camera's won't be able to do...
4. You will need the 5Ghz range to do 800m!

1. done this before on 2.4Ghz not a problem small files over an 8 hour period but not over great distance.
2. B is fine
3. Equipment can directly FTP but would prefer to go to netbook first store images there and then upload copies

really the question is how to simultaneously connect on our network as well as hot spot.

All you need is your router on your network to forward TCP port 21 to one of your computers (The FTP server).

Then it becomes available to everyone on the internet...

What make and model router do you have? I'll see if I can find some instructions...

Both computers at either end need to access the hot spot. one uploading the other downloading. I have attached the router manual.

Only the computer you are sending the files to needs changing.

1. It needs leaving on whilst your sending images to it
2. It needs a FTP server
3. The router needs port 21 forwarding

I'll read the notes and let you know about the router, no changes need to be made on the laptop sending the images.
