Guidelines For Roaming; Wireless Standard Support; Network Names; Security Settings - Avaya AP-3 User Manual

Once initialized, the network administrator can configure each unit according to the network's
requirements. The AP functions as a wireless network access point to data networks. An AP
network provides:
Seamless client roaming
●
Easy installation and operation
●
Over-the-air encryption of data
●
High speed network links
●
To be fully operational, the AP-3 needs at least one wireless card installed.

Guidelines for Roaming

Wireless Standard Support

An AP can only communicate with client devices that support its wireless standard. For
example, an 802.11a client cannot communicate with an 802.11b AP and an 802.11b client
cannot communicate with an 802.11a AP. However, both 802.11b and 802.11g clients can
communicate with an 802.11b/g AP.

Network Names

All Access Points must have the same Network Name to support client roaming.
●
All workstations with an 802.11 client adapter installed must use either a Network Name of
●
"any" or the same Network Name as the Access Points that they will roam between. If an
AP has Closed System enabled, a client must have the same Network Name as the
Access Point to communicate (see

Security Settings

All Access Points and clients must have the same security settings to communicate.

Cell Coverage

The Access Points' cells must overlap to ensure that there are no gaps in coverage and to
●
ensure that the roaming client will always have a connection available.
The coverage area of an 802.11b or 802.11b/g AP is larger than the coverage area of an
●
802.11a AP. The 802.11b and 802.11b/g APs operate in the 2.4 GHz frequency band; the
802.11a AP operates in the 5 GHz band. Products that operate in the 2.4 GHz band offer
greater range than products that operate in the 5 GHz band.
