Instawave is a good choice for small networks that need maximum flexibility and simplicity. To
use Instawave you must configure the AP-2 with “mode: Instawave” and set the Channel on
the remote stations to the same number as on the AP-2.
2.3 Advantage of StructureNet
When StructureNet is enabled each wireless station must associate with a single access point.
That access point is responsible for receiving and sending all data to the station. A station
cannot be associated with more than one access point at a time. The disadvantage of this is
that peer-to-peer communication requires that a message be sent twice — once to the access
point and a second time to the destination station. However, the advantage of StructureNet is
that the MIS manager can have more control over the connections because they pass through
a single access point. Also because each station associates with only one access point at a
time, it is possible for the station to dynamically change radio channels when switching from
one access point to another. This is known as “multi-channel” roaming.
In larger networks where the manager wishes to have more control over connections and may
wish to implement a radio cell organization in which each radio cell is on a different radio
channel, StructureNet

is a good choice.
If this is your first experience with the Access Point we recommend that you use Instawave for
initial testing and, if required, change to StructureNet once you are satisfied with the operation
of the wireless network.
To use StructureNet you must configure the AP-2 with “mode: StructureNet” and configure
the mobile stations with the same ESSID value as on the AP-2.
2.4 Roaming
With multiple LAN Access Points installed, a user can roam from cell to cell and maintain a
wireless connection to the server. For example, a user at location A will be served by cell site
1. At location B, either cell 1 or 2 will serve him. Likewise, when the user roams out of cell
site 2, he will be picked up by cell site 3.
