- 900 MHz
- 60 GHz
- 2.4 GHz
- 5 GHz
|
Explanation and Hint: 900 MHz is an FCC wireless technology that was used before development of the 802.11 standards. 900 MHz devices have a larger coverage range than the higher frequencies have and do not require line of sight between devices. 802.11b/g/n/ad devices all operate at 2.4 GHz. 802.11a/n/ac/ad devices operate at 5 GHz, and 802.11ad devices operate at 60 GHz. |
