What is the practical number of simultaneously operating Piconets and how does MB-OFDM compare to other proposals?
The practical number of simultaneously operating piconets will depend on the relative distances of the transmitter and interferer to the victim receiver and the transmission duty cycle of the interferers. Generally a mode 1 system (3 bands) can tolerate one interfering transmitter that is nearer than half way between the transmitter and receiver. For 2 interfering transmitters, they need to be placed a little bit further than the piconet transmitter. For 3 interfering transmitters, they need to be more than one and a half further than the piconet transmitter. Note these numbers refer to the actual systems that are transmitting at any point in time. In most cases, this may include a larger number of piconets whose transmissions are intermittent For the other proposal, their results show worse performance for the one interferer case, and better performance for the 2 and 3 interferer case.
