The IEEE 802.11a/n physical layer technologies utilize the 5 GHz frequency band. What is true of
the two lower bands (UNII-1 and UNII-2) in this frequency spectrum? (Choose two)
The frequency range of these bands is 5000 MHz – 5200 MHz
Each of these two bands contain five 20 MHz channels.
Regulatory domains worldwide require DFS and TPC in these bands.
These bands have a total combined bandwidth of 200 MHz.
20 MHz in each of these bands is reserved as a guard band.
