I am looking in to the feasibility of offering wireless internet access in my corner of the world.
Could someone please give me some general guidance on the following information and recommend equipment?
There are currently 3 construction camps that I would like to offer Wireless access to.
There is a base office, which is approximately 2 miles from Site1, 4 miles from Site 2 and 6 miles from Site 3. All sites have site sheds (thin metal outer coating) that have been modified in to accomodation.
Each site is approximately 200x200 yards in dimension.
All sites should be able to allow 100 - 500 users simultaneous access.
I need to find out what Cisco Products should be used, how many and where they should be placed (in very general terms).
Currently there is no line of sight between the base office and the remote locations, but there is a hill with a tower that would provide line of sight to all construction camps.
I can provide more information and drawings/maps if that would help.
You will need a wireless backhaul from your base office to the water tower (multipoint) and then to your remote sites. At the construction camps, you might was to do a wireless mesh setup. This is kind of hard to design without know what you really can and can't do. 100-500 users at one time is alot (Cisco recommends 25-30 or so users per AP), but it also depends on what kind of traffic and how much bandwidth you require. The backhau is probaly your most important part you really need to look at. Cisco makes bridges that go up to 54mbps (you won't get that though) which migh or might not be enough for you. There are other vendors who specialize in wireless bridges with throughput of 100mb up to a Gig. But a set of these can run you from $20,000 up.
Mesh has been used in construction sites, due to the fact that you only need to supply power and don't have to worry about cabling cat5 to each ap location.
I know that this didn't answer all you questions, but hopefully this help some how.
You can use the 1500's as long as that gives you enough bandwidth for the backhaul. The 1252's should be in a NEMA enclosure, but again with using the 1252's you need to cable to each ap and be within 300' from a switch.
