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 Interfaces).
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.
