The SATELLINE-3AS VHF belongs to SATEL’s
concept of remotely manageable radio
modems. In addition to ordinary communication
functions it oers conguration through radio,
eicient diagnostics tools and accumulation
of operation statistics data.
The management and surveillance of a
network of 3AS VHF radio modems is eected
through the Master Station connected by a
serial interface to a PC with dedicated
Network Management soware.
A special advantage of the SATELLINE-3AS
VHF, operated in a VHF frequency band, is the
wider coverage. With the same carrier power
and antenna gain, the connection ranges are
30 to 50 per cent larger than those reached
with an equivalent UHF radio modem.
SATELLINE-
3AS(d) VHF
of metres up to around 80 kilometres. Thanks to
a store and forward function, any radio modem
in a network can be used as a master station,
substation and / or repeater.
SATEL radio modem networks are exible, easy
to expand and can cover a wide variety of
solutions from simple point-to-point connections
to large networks comprising hundreds of modems.
Even for expanded networks, only one operating
frequency is required.
Setting up a local data transfer network is
quick and cost eective with SATEL radio
modems. The wireless network is independent
and free of operator services. The cost of
operation is either free of charge or xed,
depending on the frequency used. SATEL
radio modems are type-approved in
over 50 countries.
SATEL radio modems are always on line and
provide reliable, real-time data communications
over distances ranging from tens or hundreds

Distributor:
The SATELLINE-3AS VHF operates
on the 135...174 or 218...238
MHz frequency bands. The radio
modem is compatible with the
most widely used serial interfaces
RS-232, RS-485 and RS-422. The
SATELLINE-3AS(d) VHF with 5 W
output power and a heat sink
is the appropriate choice when
continuous transmission (when
transmitter duty cycle exceeds
20%) is required. In mobile eet
management applications, use of
VHF frequencies reduces signal
fading signicantly.
Reliability and eiciency
A SATELLINE-3AS(d) VHF network
consists of remotely adjustable
radio modems controlled through
the Master Station by the dedicated SATEL NMS PC soware.
The user data and NMS information are transferred
seamlessly together. The Network Management System
provides easy conguration of the network and advance
indication of faults, for maximum reliability, labour-saving
maintenance work and eicient system management.
The NMS radio modems monitor, on a continuous basis, the
condition of the radio connection, in particular the strength
of the signal (RSSI) and the voltage level of the power
source as well as the inside temperature of the modem. The
information is transmitted to the SATEL NMS PC soware,
where it is stored and displayed as logs and trend data.
With the help of the graphical display of the network available
at the SATEL NMS PC soware, the user can conveniently
congure, add or remove radio modems as well as set
repeater links, without need of a terminal.
Technical Specications SATELLINE-3AS(d) VHF
The equipment complies with the EN 300 113, EN 301 489-1, -5, EN 60950-1 and
FCC Part 90 specications.
