ZyAIR Access Point Series User’s Guide

The ZyAIR may be prone to RF (Radio Frequency) interference from other 2.4 GHz devices such as microwave ovens, wireless phones, Bluetooth enabled devices, and other wireless LANs.

Output Power Management

Output Power Management is the ability to set the level of output power.

There may be interference or difficulty with channel assignment when there is a high density of APs within a coverage area. In this case you can lower the output power of each access point, thus enabling you to place access points closer together.

Multiple ESS

The ZyAIR’s Multiple ESS (Multi-ESS) function allows multiple ESSs to be configured on just one access point (the ZyAIR). Different wireless stations can use different ESSIDs to associate with the same AP. Only wireless stations with the same ESSID can communicate with each other. This allows the AP to logically group wireless stations in a manner similar to VLAN (Virtual LAN). This feature is not available on all models.

VLAN

A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Only stations within the same group can talk to each other. Stations on a logical network can belong to one or more groups. The ZyAIR supports 802.1Q VLAN tagging. Tagged VLAN uses an explicit tag (VLAN ID) in the MAC header of a frame to identify VLAN membership. The ZyAIR can identify VLAN tags for incoming Ethernet frames and add VLAN tags to outgoing Ethernet frames.

Configure VLAN (virtual LAN) with multi-ESS to extend the wireless logical grouping to the wired network. Each ESS is assigned a unique VLAN ID. This feature is not available on all models.

Limit the number of Client Connections

You may set a maximum number of wireless stations that may connect to the ZyAIR. This may be necessary if for example, there is interference or difficulty with channel assignment due to a high density of APs within a coverage area.

SSL Passthrough

SSL (Secure Sockets Layer) uses a public key to encrypt data that's transmitted over an SSL connection. Both Netscape Navigator and Internet Explorer support SSL, and many Web sites use the protocol to obtain confidential user information, such as credit card numbers. By convention, URLs that require an SSL connection start with “https” instead of “http”. The ZyAIR allows SSL connections to take place through the ZyAIR.
