2.1.1 Point-to-Point
In a typical point-to-point application, shown in Figure 2, unit A communicates directly with unit
B. You can implement the link in either bridging or routing mode.

2.1.2 Repeater
You can set up a repeater by using two NCL1135 units back-to-back.
In the configuration shown in Figure 3, unit A communicates with unit B via the back-to-back
NCL1135 repeater configuration of units C and D. You must use different frequencies for each
leg of the path. Use this configuration to circumvent large obstacles in the radio link path, or
when the link from unit A to unit B is too long to provide reasonable signal levels and data
throughput.
Figure 3 Repeater Application
In this configuration, the effective data throughput from unit A to unit B is the same as the
lessor data throughput from unit A to unit C or unit D to unit B. That is, the throughput through
a series of links will be that of the slowest link.
You can implement this configuration in either bridging or routing mode.
