Question

Select the correct statements regarding frequency hopping algorithm used by Bluetooth.

a. The operation bandwidth is comprised of 79 1MHz-wide channels in which frequency hopping is implemented

b. The maximum rate of frequency hopping used by Bluetooth is 1600 hops per second

c. Time Division Duplex (TDD) is implemented to enable all devices to operate within the same medium

d. All of the above

Answer 1

Frequency hopping algorithm used by Bluetooth:

Frequency hopping main purpose is avoid interference issues.

• The operation bandwidth is comprised of 79 1MHz-wide channels in which frequency hopping is implemented
  • The ISM is 2.4 GHz from that Bluetooth uses 79 radio frequency channels and each one is 1MHz-wide.
• The maximum rate of frequency hopping used by Bluetooth is 1600 hops per second.
  • It is found at the signal switches carrier channel used by bluetooth whose speed is 1600 hops per second.
• Time Division Duplex (TDD) is implemented to enable all devices to operate within the same medium
  • Example of this is  Bluetooth piconet., it support two way processing .In this time is devided and the medium remains same.
