Guidelines for Roaming
• An 802.11a client can only roam between 802.11a Access Points. An 802.11a
client cannot communicate with 802.11b Access Points.
• All 802.11a Access Points must have the same SSID.
• All workstations with 802.11a client adapters installed must use either an SSID of
“any” or the same SSID as the Access Points that they will roam between.
• All 802.11a Access Points and clients must have the same security settings to
communicate.
• 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.
• All Access Points in the same vicinity should use a unique, independent Channel.
• Access Points that use the same Channel should be installed as far away from
each other as possible to reduce potential interference.
