Hi, I'm new there.

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 ?

Thank you

(several Mo in size)

What is a Mo?

is it possible to send data from a point A to a point B without using bluetooth ? If so, how ?

How about wires?

Looks like yet another well thought out question...

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.

A great freeware protocol stack for many radios. Arduino compatible.

these can do a star or mesh topology. or simple point to point. Nodes have addresses.

What's the range between A and B that we are talking about? Km/miles? Longer? Or 10s of meters/yards?

I never heard of the unit 'Mo' either. Also, cheaper and safer, compared to what? And what is unsafe about it.
