Security	Encryption Types - WEP, TKIP, AES***
	WPA 1.0 compliant
	Encryption Key lengths Supported: 64 bits, 128 bits, and 152 bits
	(Atheros module using AES encryption only)
	802.1x/EAP
	CCX 1.0 compliant
Maximum recommended number of computers to	10 units or less ****
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.
