1.3. Examples of Data Communication Links
l Example 1 - Point-to-Point Link (on page 12)
l Example 2 - Point-to-Point Link with Repeater (on page 12)
l Example 3 - Standard Point-to-Multipoint Network (on page 14)
1.3.1. Example 1 - Point-to-Point Link
Figure 2 shows the most common and straightforward link, a Master communicating to a Slave in
a Point-to-Point link.

1.3.2. Example 2 - Point-to-Point Link with Repeater
Figure 3 shows a link using a Repeater.
l If a Repeater is located on a hilltop or other elevated structure, it can enhance the link from
the Master to the Slave.
l In this configuration, it is desirable to use an Omni-directional antenna at the Repeater.
l Yagi antennas may be used at both the Master and Slave radios to increase the range of
the link.
Note: Adding Repeaters to a network cuts the data throughput by 50% and decreases overall
network capacity by 50%.
