RF-Link Technology NL6000 manual Features

Page 7

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.

The NL6000 can transmit in any of the following frequency ranges:

VHF 136 ￿ 162 MHz

VHF 148 ￿ 174 MHz

VHF 216 ￿ 235 MHz

UHF 400 ￿ 420 MHz

UHF 450 ￿ 470 MHz

1.1.Features

The following list highlights the primary features of the NL6000:

Product Reliability

The NL6000 makes extensive use of Digital Signal

 

Processing (DSP) technology resulting in outstanding

 

performance under adverse environmental conditions.

Data Reliability

Advanced signaling end error control technologies

 

provide exceptional performance under poor channel

 

conditions.

RF Data Rate

The NL6000 can transmit or receive at over-the-air rates

 

of 12,000 bps within narrowband or 22,050 bps within

 

wideband channels.

Protocol Flexibility

The NL6000 provides three data transmission modes

 

resulting in peak system performance for a wide range of

 

data communication scenarios.

Easy Use Interface

An easy to follow menu-based user interface makes

 

configuring the NL6000 a simple task.

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.
