Option 2—Using the AP as a Store-and-Forward Packet
Repeater
A wireless network can be extended through the use of an alternate
arrangement using the Access Point as a repeater to re-transmit the sig-
nals of all stations in the network. The repeater is a standard transceiver
configured as an Access Point, and operating in Store and Forward
mode. (See
Figure 1-8
.)

Figure 1-8. Typical network with store-and-forward repeater
As with the conventional repeater described in Option 1 above, the loca-
tion of a store and forward repeater is also important. A site must be
chosen that allows good communication with both the Access Point and
the outlying Remote site. This can be on the top of a hill, building, or
other elevated terrain from which all sites can be “seen” by the repeater
station antenna. A detailed discussion on the effects of terrain is given
in
Section 5.1.2, Site Selection (beginning on Page 131)
1.3.2 Protected Network Operation using Multiple
Access Points
Although MDS transceivers have a very robust design and have under-
gone intensive testing before being shipped, it is possible for isolated
failures to occur. In mission-critical applications, down time can be vir-
tually eliminated by using some, or all, of the following configurations:
In a point-to-multipoint scenario, the Access Point services multiple
remotes. A problem in the Access Point will have an effect on all
remotes, since none will have access to the network. When operation of
the network does not tolerate any down time, it is possible to set up a
protected configuration for the Access Point to greatly reduce the possi-
bility of this occurrence.
Two or more Access Points can be configured with the same Network
Name and kept active simultaneously, each with its own independent
antenna. In this scenario, Remotes will associate with either one of the
available Access Points. In case of a failure of one of the AP’s the
Remotes will quickly associate with another of the remaining Access
Points re-establishing connectivity to the end devices.
