Introduction

The RT-XLAN is a long range radio that extends and improves the communication
between vehicles in an RT-Range application. The RT-Range S or original RT-Range
is a system that can measure the range from one vehicle to other vehicles in real-time
and output its measurements on the CAN bus. It is used for the development of active
safety systems in cars.

The RT-XLAN is designed for easy connection to the RT-Range S systems. It is also
possible to use it with the standard RT-Range systems providing a Y cable converter kit
is purchased. The standard RT-Range has a range specified to around 200 m in open
environments where there is no interference. The RT-XLAN radios are specifically
designed for outdoor use and have a robust, weatherproof design that can operate
within a wide temperature range. They also feature a low-loss integrated N-type RF
connector replacing the need for radio-to-antenna cable connections that can become a
weak link. The RT-XLAN is capable of reliably improving the data communication
throughout the range and will also extend the distance between vehicles to around 1km.

Features

There are several features that make the RT-XLAN ideal for use on vehicles with the
RT-Range. These include:

 Around 1 km robust connection where there is line-of-sight between vehicles.
 Highly reliable link with very few dropped packets, even at the longer ranges.
 Superior latency so that it is very rare for packets to take longer than 10ms

between vehicles.

 Powerful suction mounts secure the unit onto vehicles, avoiding the need to strap

the radio down.

 Wide temperature range, making the RT-XLAN suitable for use in winter and

summer conditions.

 Uses standard 2.4GHz radio frequency so can be used license-free in many

countries.

Models

There are two models in the RT-XLAN family. A base unit is needed to set up the
network and then multiple client units connect to the base-unit. The base unit acts as an
access point and all the clients connect to this access point to share their data.

Both the base unit and the client unit come with the same parts. Table 1 lists the parts
that are delivered with an RT-XLAN and Figure 1 shows the RT-XLAN and its
components.
