Technical data
Typical op erating distances** • 802.11a: 40 ft. (12 m) @ 54 Mbps; 300 ft.
(91m)@6Mbps
• 802.11ac: 4 0 ft. (12 m) @ 54 Mbps; 300
ft.(91 m) @ 6 Mbps
• 802.11b: 100 ft. (30 m) @ 11 Mbps; 300 ft.
(91m)@1Mbps
• 802.11g: 100 ft. (30 m) @ 54 Mbps; 300 ft.
(91m)@1Mbps
• 802.11n: Estimated double the operating
distance of 802.11g and 802.11a in their
respective frequencies
Number of chan nels
• 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
Security
Encryption types: compatible with WEP, TKIP,
AES***, WPA 1.0 and WPA 2.0
Encryption key, lengths suppo rted: 64 bits and
128 bits
Maximum recommended numb er of computers
to be connected over wireless LAN (during ad
hoc connection)
10 units or less ****
* “Wi-F i based” indicates that the interconnectivity test of the organization which guarantees the
interconnectivity of wireless LANs (Wi-Fi Alliance) was passed.
** Th e operating distances given above increase o r decrease depending on factors such as the
number of walls, reflecting material or interfe rence by e xternal RF sources.
*** Network k ey encryption (WEP) occurs with the n umber of bits given above, after d eduction of
the fixed length of 24 bits the user may however also set 40 or 104 bits.
**** Depending on the particular practical application, the number of computers which can be
networked is reduced if necessary.
