you would propably need to install several BT antennas in different parts. Note that even when you can get 100 meter range for some PC BT cards, phones with lower power requirements, are usually bound to around 10 meter range.

you mean these antenas can work as repeater so message sent from bluetooth dongel with range(100 m) can reach to mobile device (10 m) each of them have 500 m distance between them through these antenas

Hi,
There is no way to increase the power of TX in BT side. It means you can formed a scattered net to reach the destination point (like repeater)

Hi,
I think this is going to be hypothetical (and complex), you create a chain network. You can take a look in this doc found in forum nokia (Bluetooth Technology Overview).
