The NL6000 s powerful and efficient packet communications protocol provides a solution to
many of the problems affecting conventional wireless data networks. Bursts of noise, RF
interference, inter-modulation, overload, and signal fade can corrupt and interrupt radio data
links. The NL6000 eliminates these problems through the use of advanced technologies
including sophisticated forward error correction technology.

Base Station Configuration
The NL6000 can be configured as a remote or a base
station. A remote transmits data to a specific unit or group
of units. A base station transmits data to multiple units or
groups.

Repeater Configuration
In areas where you lack a reliable path, you can
configure an NL6000 unit as a repeater to reach a
hidden unit. This feature can fill in RF blind spots or
extend the usable range of the system s desired
coverage area.
