To begin with something that works in simply 1 room like a class room etc would do just fine, cheers for the info i'll check out the nrl thingies, have a couple of arduino's hooked up and see where it takes me.. cheers
1.2km that's insane distance, the bit rate for me would be just fine the 9600 mark, i could easily send what i need in 50 - 100 bytes so not a problem i was just getting carried away with future idea's lol, but i was think, use a sweeping motion to your right or left to call up a preprogrammed spot which tells your friend with the glove that you're wanted, they could shake to remove that alert.. basically implementing a protocol for these gloves...
question, is, who would be interested in this type of thing?.
