4. Wireless Link Mode and Wireless LAN Function

NZ2WL - xxx

MAC address filtering

This function can be used only when the product is configured as an access point. This function enables

only the terminals whose MAC address has been registered to be connected.

Bridge packet control

This function can be used only when the product is configured as an access point. An AP can pass only

data from network devices whose MAC address has been registered to the AP. Communication between

wireless terminals can be rejected when their MAC addresses are unregistered.

WSL (Proprietary encryption)

WSL (Wireless Security Link) is unique proprietary encryption built only in the NZ2WL series of

devices. It can be used either alone or along with other types of encryption such as WEP and AES.

Note, however, that devices using WSL cannot communicate with those not using it.

Data encryption

This function encrypts wireless data. For encryption, four security protocols are available: WEP (Wired

Equivalent Privacy), AES, AES-OCB and TKIP. AES and TKIP can be used with WPA, WPA-PSK,

WPA2, WPA2-PSK, WPA-AUTO, and WAP-AUTO-PSK.

Super A/G

Proposed by Atheros Communications, Inc., this technology speeds up communication. It improves

the throughput of wireless LAN using three techniques: "fast frames" for raising data transfer efficiency

by increasing the data packet size, "bursting" for decreasing inter-packet wait time, and "compression"

for compressing and decompressing data in real time.

VLAN function

This function can be used only when the product is configured as an access point. This function

organizes terminals on a network into virtual groups regardless of the physical configuration of the

network.

WDS function

This function can be used only when the product is configured as an access point. This function is a

wireless communication function between APs. An AP can wirelessly communicate with other APs

while communicating with a station.

Promoted by Atheros Communications, Inc., this technology makes the communication distance longer,

compared with the existing communication distance, although the communication speed decreases. XR

can be used both in IEEE802.11a and IEEE802.11g specifications. For communication using XR, the

product must be connected to a device which supports the XR technology and has the XR function

enabled. If it is connected to any other device, XR will not be used and only the regular wireless

communication is available.
