Bluetooth IC

^^^^^^^^^^^^^^^^^^^^^^^^

How many of these are you going to put on a desktop.

Bluetooth will barly get to the next room !!!

if you can mount a tower over the worksite you may be able to put a high speed ir reciever on each thing and control em over tcp/ip. maybe get someone with a license to use a low population radio band and do wireless that way, there's some hobbyest channels that require a license, i think

Well, in fact there are 3 classes of bluetooth transceivers defined in the standard. The most common has a transmitter of about 1mW, but nowadays you can also find cheap "class 1" transceivers with 100mW transmitters that should have a > 100m free field range.

In the long run, the communications transmitted are more important than the communications. These are going to be model sized(using modified tonka trucks). And will at most, operate over a range of about 100 yards(at most, more likely is 10 yards). Also, they do not require continuous transmission, but rather can transmit information when within range of each other. The information is mostly used to synchronize, not control. The control will be done onboard the individual vehicles. For this reason, we have viewed bluetooth as being sufficient. The problem we are having now is finding an easy(and preferably semi-cheap) way of integrating bluetooth into these devices. The chips I've seen so far have had development environments costing

forgot the M, i remembered that some rc airplane pilots use a licensed frequency, round 75Mhz.
