data rate
Active frequency
•
802.11n: 2.4 GHz or 5 GHz
•
802.11b/g: 2400~2473 MHz
•
802.11a: 4900~5850 MHz
•
802.11a: 2.4 GHz / 5 GHz
Typical operating distances**
•
802.11a: 40 ft. (12 m) @ 54 Mbps; 300 ft.
(91 m) @ 6 Mbps
•
802.11ac: 40 ft. (12 m) @ 54 Mbps; 300
ft.(91 m) @ 6 Mbps
•
802.11b: 100 ft. (30 m) @ 11 Mbps; 300 ft.
(91 m) @ 1 Mbps
•
802.11g: 100 ft. (30 m) @ 54 Mbps; 300 ft.
(91 m) @ 1 Mbps
•
802.11n: Estimated double the operating
distance of 802.11g and 802.11a in their
respective frequencies
Number of channels
•
802.11a: 8 independent channels
•
802.11b/g: 11 channels, 3 non-overlapping
channels
•
802.11n: Channel bonding takes two of
the non-overlapping 20MHz channels and
combines it into one 40MHz channel. It is
actually 12 non-overlapping channels with
channel bonding and 24 without. Also it is 1
non-overlapping channel in 2.4GHz when
channel bonding is used.
•
802.11ac: 5 independent channels
