These modules are all pretty expensive - is there anything cheaper?
XBee is based on a chipset that integrates xmit and recv functions - you won't get them separately.
But XBee only has 300ft (100m) range , I need the range that the Xbee Pro offers - up to 1 mile range
1. Would I be able to design a RF transmitter and receiver with the specs that I gave above , so that the final production cost of the transmitter and receiver would be around $10 each ? ( assuming order quantities of 5000 )
but RF design is not cheap, and you have to get FCC type acceptance if you design your own module (not an issue if you purchase complete modules that already have FCC certification), which likewise costs a bunch of money.
This is an interesting project. Try looking in to FSK. Its what was used in the old modems. You can use this to send data on a normal audio line. Hook this up to a cheep walki talki or something like that. There is IC for this. Or you can build it from scratch FSK is pretty simple, but implementing it could be a little hard. Using this you don't have to build you're own receiver.
