ORiNOCO Wireless Client
User Guide
Chapter 3 Wireless Topologies
27
As the mobile client seamlessly switches from cell to cell, its network connectivity is preserved.
The user can move freely between the Access Points in the network. When the roaming client
leaves the transmission range of one Access Point, the card automatically detects the other
Access Point(s) in the same vicinity to continue the network connection.
3-3-3 Guidelines for Roaming
An ORiNOCO Wireless Client can roam between 802.11a Access Points, 802.11g Access
Points and 802.11b Access Points.
All 802.11a, 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
802.11a, 802.11a 2X Turbo, 802.11g and 802.11b Access Points.
All workstations with ORiNOCO Wireless Clients installed must use either a Network Name of
“any” or the same Network Name as the Access Points that they will roam between (this
assumes that the AP is not a closed system; see “Network Name” for more information).
All Access Points and ORiNOCO Wireless 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.
Access Points installed in the same vicinity that use the same frequency band (2.4 or 5 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.
