Multi-Hop Configuration (Relay) - Alvarion BreezeNET PRO.11 Series User Manual

3. Install several Access Points in the same location a few meters from each other
so they cover the same area. Be sure to position the Access Points at the highest
points possible.
4. To allow roaming and redundancy, configure all Access Points and stations
adapters to the same ESSID.
5. To improve collocation and performance, configure all Access Points to
different hopping sequences of the same hopping set.
6. Install Station Adapters or SA-PCR cards on workstations.
7. Make sure that the Load Sharing option is activated. Stations will automatically
associate with an Access Point that is less loaded and provides better signal
quality.
Note: It is not necessary at this point to connect the Access Points to an Ethernet

5.1.4 Multi-Hop Configuration (Relay)

When you need to connect two sites and no line-of-sight exist between them, an
AP-WB pair can be positioned at a third location where line-of-sight exists with
each of the original locations. This third location then acts as a relay point.
In areas where a wired LAN backbone is not available, another AP can be added to
the AP-WB relay to distribute a wireless backbone. In this manner, the range of a
wireless system can be extended.
To set up a BreezeNET multi-hop cell:
1. Install an AP at the main office (refer to Chapter 2 for installation instructions).
2. Install a WB at the remote site.
3. Install an AP-WB pair in a high location that has a clear line of sight to both the
main office and the remote site. Many AP-WB pairs can form a chain.

backbone, since Access Points continuously transmit signals (beacon frames)
whether they are connected to an Ethernet backbone or not.
