Question

Select the correct statement(s) regarding Bluetooth piconet and scatternets.

a. piconet/scatternet scheme allows many devices to share the same physical area and make efficient use of the bandwidth

b. within the piconet, the master determines the channel and frequency hop sequence that will be used by all devices

c. data collisions can occur if devices in different piconet, on different logical channels happen to use the same hop frequency

d. all statements are correct

Answer 1

Answer is D.

since,

One of the main advantage of Piconet/Scatternet scheme is that it allows many devices to share the same physical area and make efficient use of the bandwidth, so a is true,

In piconet, the master determines the channel frequency hopping sequence as well as the phase, that will be used by all devices. so, b is also true

When devices in different piconet, on different logical channels tries to use the same hop frequency at the same time, Data collisions occurs, and hence c is also true.

So, we can say that answer is D
