This result indicates that the effect of this cable will most likely prevent your
wireless link from operating at both High and Medium Speed. In such situations
you are advised to:
■
Relocate the Outdoor Router hardware to a location that allows you to use a
shorter cable length.
■
Increase the height of the antenna on the mast and/or install taller antenna
masts to increase the signal path clearance.
■
Trade-off data speed versus range, and recalculate the ranges that could be
achieved at lower Transmit Rates.
Alternatively, you may decide to perform on-site diagnostic measurements to
validate the results of this calculation. Please consult the "Avaya Wireless OR
Manager - User’s Guide" for information about using the Wireless Link Test
feature to perform on-site diagnostic measurements.
The "Avaya Wireless OR Manager - User’s Guide" is available in electronic
format on the Avaya Wireless Outdoor Router CD-ROM.
Point-to-MultiPoint Links
Suppose you are installing a wireless Point-to-Multipoint link between one
Avaya Wireless Central Outdoor Router and two Remote Outdoor Routers as
pictured in Figure 3-4 below, where:
■
The Central Outdoor Router in building
c
is connected to a 7 dBi Omni-
Directional Base Station Antenna, and
■
The two remote sites
a
and
b
have been equipped with a 14 dBi Directional
Antenna.
■
All sites have been connected via 15m.(50 ft.) antenna cables.
■
The site is located in the Europe, which requires you to use ETSI approved
equipment
