Recently, i’ve been looking for (without finding) the best way (cheaper, safer, …) to send and receive data (several Mo in size) from a place not connected to any kind of physical network. Power will be provided by batteries. Also, the place from where I’ll send (and receive) data to (from) this isolated spot is too far to use bluetooth technology.
I’ve thought about gsm/3g networks, but are we forced to pay an submission to use a 3g key for example ?
Actually, my question is : is it possible to send data from a point A to a point B without using bluetooth ? If so, how ?

Use wires if at all possible; Infinitely simpler. Like two microprocessors’ UARTs, 3 conductor doorbell type wire. TX to RX, RX to TX, GND.
Use some mini-wireless boards. Atmel AVR + RFM69W or HW full duplex radio on same board, as is MB’s of flash.
