Type of network For Intel® Wilkins Peak2: Intel® Dual Band Wireless-N 7260
For Atheros® WB222: Qualcomm Atheros® AR946x Wireless Network Adapter
Transfer rate (Automatic switching) IEEE802.11 a and g: 54 Mbps max. data rate; IEEE802.11n:
300 Mbps max. data rate
Active frequency • 802.11n: 2.4 GHz or 5 GHz
• 802.11b/g: 2400~2473 MHz
• 802.11a: 4900 ~ 5850 MHz
Typical operating distances** • 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.
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
Security Encryption Types - WEP, TKIP, AES***, WPA 1.0 and WPA 2.0 compliant
Encryption Key lengths Supported: 64 bits and 128 bits
Maximum recommended number
of
computers to be connected over
wireless LAN (during ad hoc
connection)
10 units or less ****
* “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 decrease
