Point-to-Point Links
3
Suppose you are installing a wireless point-to-point link between
two Remote Office Routers as pictured in Figure 3-4 below, where:
■
Both sites have been equipped with a 14 dBi Directional
Antenna, connected via 6m.(15ft.) antenna cables.
■
The distance between site
a
and
b
is 4 km. (2.5 mi.).
■
The site is located in the US, which allows the use of FCC
approved equipment.
Figure 3-4 Calculating the Point-to-Point Range
Looking at Table 3-1 on page 3-5, we learn that a High Speed link
between two 14 dBi Yagi antennas may cover a maximum distance
of 5.6 Km.(3.4 mi.), provided that the signal path clearance is 9.8
m. (32.2 ft.) or better.
Now let’s calculate the probable range for this example using the
formula introduced on page 3-2:
Range = Maximum Range x Cable Factor x Clearance Factor
