Please can anyone help?
Is it possible to connect your phone to a 100m bluetooth adapter (at a
distance of 100m), or is it still limited to 10m?
Interested in buying a 100m adapter.

TIA.

Rapidblue.

You only get the longer range if it's supported by devices at both ends of the
connection, and the phone is still limited to the shorter range.

Oh, I see.
A friend (he's pretty clued up in PCs) told me that WiFi (which usually
works about 30m) can work over longer distances if a booster is attached to
the device. Even if only the one device has a booster attached and the other
device is still limited to the shorter range, they will work together
according to the larger of the two ranges. Wasn't sure if this was the case
with bluetooth too. But then, did anyone hear about those guys (not sure
what part of the world they were in) that made that bluetooth device that
looked almost like a rifle? It had some or other major booster in it. They
used it to bluejack / bluesnarf people from considerable distances away. Now
how did they get that right if the phone is still limited to 10m?
Anyway, was just hoping that bluetooth phones could work further :-(

For the "booster" to work over greater distances towards a non-boosted
device, both the transmitter and receiver on the boosted end would have
to be boosted. The simple way to do this is to use an antenna that has
gain compared to a "normal" antenna. The way to make an antenna have
gain, is to make it directional.

The bluetooth rifle you heard about had a yagi antenna, which is highly
directonal compared to the BT-antenna in a phone.
