Planning and Installing Wireless LANs
BreezeNET PRO.11 Series 4-11 User’s Guide
4.1.4. Multi-hop Configuration (Relay)
When you want to connect two sites between which a line-of-sight does not
exist, 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 way, the
range of a wireless system can be extended.
System configuration is as follows:
⇒⇒ To set up a BreezeNET multi-hop cell:
1. Install an AP at the main office (refer to section 2, Basic
Installation).
2. Install a WB at the remote site (refer to section 2, Basic
Installation).
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.
4. When an AP and WB communicate over the wireless LAN, set
them both to the same ESSID. For example, set the AP of the main
office and the WB of the first AP-WB relay pair to the same
ESSID. Also, set the AP of the last AP-WB relay and the WB of
the remote site to the same ESSID; this ESSID should be different
from the first ESSID.
Another option is to use one ESSID, and to set the Preferred AP
parameter of each WB to its paired AP (refer to section 3.4.3). This
option allows stations to roam between the sites.
5. As usual, make sure that the hopping sequence of the Access Points
are different.
