3-2-2 Roaming Principles
A LAN-Express IEEE 802.11 Wireless Adapter can roam between 802.11g Access Points
and 802.11b Access Points.
All 802.11b and 802.11g Access Points that a client will roam between must have the
same Network Name. Depending on the Wireless Mode selection, a user can roam among
802.11g and 802.11b Access Points.
All workstations with LAN-Express IEEE 802.11 Wireless Adapter installed must use
either a Network Name of “any” or the same Network Name as the Access Points that
they will roam between.
All Access Points and LAN-Express IEEE 802.11 Wireless Adapter 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.
Access Points installed in the same vicinity that use the same frequency band (2.4 GHz)
should each use a unique, independent Channel to avoid potential interference.
Access Points that use the same Channel should be installed as far away from each other
as possible to reduce potential interference.
