Bluetooth / Piconets

Hello!

I am just looking at Bluetooth systems, and i am interested in some
details. Maybe someone can help me out...

- i have read some article, and there is stated, that the maximum
range of bluetooth applications is 10 meters. When will the 100m
specification become available?
- how many piconets can coexist at one place? (minimal communications
rate, one piconet consists of 1-5 slaves, and within one minute 3 to 5
bluetooth packets have to be transmitted between each slave and the
master). i have heard about applications at aeroports, transmitting
news to visitors by bluetooth, so i think some 100 piconets should be
able to coexist in that case (at that low data rate)

can you answer my questions?! please :-)

greetings,
Reinhard
