a. bluetooth implements direct sequence spread spectrum and operates in the ism frequency band
b. bluetooth implements frequency hopping spread spectrum and operates in the ism frequency band
c. bluetooth implements ofdm and operates in the licensed frequency band
d. bluetooth implements frequency hopping spread spectrum and operates in the licensed frequency band

Answer 1

The correct statement about 802.15 Bluetooth is that it uses a frequency hopping spread spectrum and operates in the ISM frequency band.

Step-by-step explanation:

The correct statements regarding 802.15 Bluetooth technology are that Bluetooth implements frequency hopping spread spectrum and it operates in the ISM frequency band. Therefore, the correct option is b. Bluetooth implements frequency hopping spread spectrum and operates in the ISM frequency band. Bluetooth uses a range of frequencies in the 2.4 GHz ISM band and dynamically switches frequencies to minimize interference and improve security.
