2 Network Considerations
APCD–NC006–A 7
2.1.2 Point-to-Point
In a typical point-to-point application, (see Figure 3), unit A communicates directly with unit B.
The NCL1170 can perform this type of link in either bridging or routing mode.
Figure 3 Point-to-Point Application
2.1.3 Repeater
In a typical repeater application, (see Figure 4), unit A communicates with unit B via back-to-
back NCL1170 units C and D, with different frequencies used for each leg of the path. You
would implement an NCL1170 in a repeater configuration whenever you need to circumvent
large obstacles in the radio link path, or when the link from unit A to unit B is too long to
maintain reasonable signal levels and data throughput.
Figure 4 Repeater Application
In this configuration, the effective data throughput among any combination of units is equal to
or less than the throughput between the slowest links.
