Roaming
With the Access Point’s roaming capability, you can break the wireless distance
barrier by installing them throughout your building. The Access Points act as
“cells,” similar in concept to those of a cellular phone network. Make sure that
the coverage of each Access Point overlaps to provide uninterrupted wireless
access at any location within the building.
Note
: The cells must overlap to ensure that there are no gaps in coverage and that the
roaming JANUS reader will always have a connection available.
In a roaming network, you should configure each Access Point for a different
channel/subchannel pair, but you must configure each one with the same
domain number and security ID. You must also configure the JANUS readers
with the same domain. These configurations ensure that the JANUS readers can
switch from Access Point to Access Point while preserving wireless
connectivity. When the roaming JANUS reader leaves the transmission range of
one Access Point, the software automatically polls the other Access Points in the
same domain to continue the network connection.
Note : Roaming stations will only roam among Access Points with the same domain
and security ID.
The following illustration displays an example of a moderately complex
network that has been set up with a roaming domain.
