Specification

 

 

Type of network

The Atheros SuperAG network card conforms to IEEE802.11a,

 

IEEE802.11b, and IEEE802.11g, Wi-Fi based*

 

 

Transfer rate

(Automatic switching) 54 Mbps maximum data rate

 

 

 

Active frequency

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

 

 

 

Number of channels

802.11a: 8 independent channels

 

802.11b/g: 11 channels, 3 non-overlapping channels

 

 

Security

Encryption Types - WEP, TKIP, AES***, WPA 1.0, WPA2,CCX

 

compliant

 

Encryption Key lengths Supported: 64 bits and 128 bits 802.1x/

 

EAP

 

 

Maximum recommended number of computers

10 units or less ****

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.
