(For Indian licence free 865–867
MHz channels)
SATELLINE-EASy is a state-of-the-art
transceiver radio modem providing
a compact and exible solution for
many dierent long range applications.
It can be equipped with an LCD and
push buttons for facilitating the
conguration of the radio modem.
SATELLINE-EASy radio modem is also
available as a radio module, called
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 re-peater.
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 net-works comprising hundreds of
modems. Even for ex-panded networks, only
one operating frequency is required.
Setting up a local data transfer network is
quick and cost eective 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

(For Indian licence free channels)
This variant of SATELLINE-EASy is ready to use
on the Indian licence free channels 865–867 MHz
with default settings. It is allocated for narrowband
telemetry, alarm and data transfer applications.
With high 1 W output power, good sensitivity,
small size and low power consumption the radio
modem meets the technical requirements set on
wireless communications in a number of applications
where controlling, monitoring, metering or alert
sensor systems are part of the operation.
Building a data transfer network is easy and
straightforward. A pair of radio modems is all
you need to set up the datalink - no conguration
is required. To have more functions the modem
can be easily congured with a terminal program
(or with the display in the modem).
The radio modem network coverage can be easily
extended by using some of the radio modems
as repeater stations. With the store and forward
function, the radio modem buers the received
data and transmits it further using the same
radio frequency as used in reception.
To minimize the energy consumption, the modem
remains in sleeping mode when idle; when there
is no reception or transmission the power level is
kept at the minimum level.
SATELLINE-EASy (for Indian licence free channels
865-867) complies with the EN 300 113-1, -2.
