To avoid interference between the two APs that form a repeater station,
they should be synchronized so that they will transmit at the same time
and receive at the same time. This eliminates the possibility of one AP
transmitting while another is trying to receive.
This can be accomplished by setting the

for details.
Option 2—Using the AP as a Store-and-Forward Packet
Repeater
You can extend a wireless network by using the Access Point as a
repeater to re-transmit the signals of all stations in the network. (See
Figure 1-10 on Page

Figure 1-10. Typical Store-and-Forward Repeater Arrangement
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

1.4.2 Protected Network Operation using Multiple
Access Points
Although GE MDS transceivers have a very robust design and have
undergone intensive testing before being shipped, it is possible for iso-
lated failures to occur. In mission-critical applications, down time can
be virtually eliminated by using some, or all, of the following configu-
rations:
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
