Maximum recommended number of computers
to be connected over wireless LAN (during ad
hoc connection)
* "Wi-Fi based" indicates that the interconnectivity test of the organization which guarantees the
interconnectivity of wireless LAN (Wi-Fi Alliance) has been passed.
** The communication ranges shown above will increase or decrease depending on factors such
as number of walls, reflective material, or interference from external RF sources.
*** Encryption with network key (WEP) is performed using the above number of bits, however,
users can set 40 bits/ 104 bits after subtracting the fixed length of 24 bits.
**** Depending on practical environments, the allowable number of computers to be connected
may be decreased.

Integrated Dual-Band Wireless-N 7260 device
conforms to IEEE 802.11a, 802.11b/g, and
802.11n, Wi-Fi based*.
(Automatic switching) IEEE802.11 a and
g: 54 Mbps max. data rate; IEEE802.11n:
300 Mbps max. data rate
• 802.11n: 2.4 GHz or 5 GHz
• 802.11b/g: 2400~2473 MHz
• 802.11a: 4900 ~ 5850 MHz
• 802.11a: 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.
• 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
Encryption Types - WEP, TKIP, AES***, WPA 1.0
and WPA 2.0 compliant
Encryption Key lengths Supported: 64 bits and
128 bits
10 units or less ****
