Telecontrol
Many remote control systems use radio modules.
Typical industrial remote-control applications using
radio include control of heavy machinery, hoists and
cranes. In the forestry industry, remote controlled
trucks and cable cranes are very useful for
transporting logs.
At construction sites, many remote control units are
used within a small area. If all units, or even two
units, use the same frequency, the radio waves
interfere with each other. For this application, FDMA
(Frequency Division Multiple Access) is recommended

Dear customer,
There are a lots of applications for radio, and we
have seen many new projects and applications in
recent years. In this issue, we would like to show
you some typical examples of SRD applications.

Telemetry
|
|
Radio is an important element of monitoring and
warning systems for natural disaster. The systems
use GPRS/GSM and SRD to cover wide areas. While
GPRS/GSM conveys the signal to a central station
located many hundreds kilometer away, SRD covers
an area of several hundreds meters and sends data
to a GPRS/GSM station without incurring any
communication costs.

Sensor networks in factories
|
|
When installing new sensors in a factory, building a
conventional wired system involves a lot of expense
and time. In addition, these systems do not allow
frequent changes to the layout of facilities, so that
more sensors must be added.
In this situation, a wireless sensor network is called
for.

Telecommand applications
|
|
There are many applications which send only a
switching signal for starting and stopping movement.
It is a simple matter however for the radio
transmitter to send the signal with an ID to avoid
malfunctions due to unrelated radio signals.
