Wireless World – Local Solution
The SATELLINE-1870E radio modem provides
a wireless transparent data link on the European
licence-free 868...870 MHz frequency band. It
is designed for tight integration into the user’s
terminal equipment, and is particularly well
suited for the transfer of data and control
messages in mediumrange
(1–10 km) applications.
In accordance with the regulations on the use
of the 869 MHz band, the maximum output
power of the SATELLINE-1870E is 500 mW. In
the design of the radio modem, special attention
was paid to ensuring reliable operation in
all circumstances. Accordingly, the technical
solutions applied in the radio part minimise
the risk of disturbance from and collision
with other services (DVB-T, TETRA, GSM)
using the ISM/SRD band.
SATELLINE-
1870E
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.
With SATEL radio modems, setting up a local data
transfer network is quick and cost eective. Your
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 typeapproved in over 50
countries. For the latest information, please visit
our website www.satel.com.
SATEL radio modems are always on line, and provide
reliable, realtime data communications over
distances ranging from tens or hundreds of metres

Distributor:
The SATELLINE-1870E operates in a transparent
transfer mode, which ensures compatibility with
most user systems and protocols. If desired, the
modem can be programmed to utilise the
addressing functions of the user’s protocol, to
provide routing or message ltering
functions. The settings of the radio modem
can be changed from an external terminal in
the programming mode or through auxiliary
SL-commands during normal operation.
In case there is a need to extend the coverage of
the radio modem network, SATELLINE-1870E
modems can be used as repeater stations. By
using the Store and Forward function, the radio
modem buers the received data and transmits
it further using the same radio frequency
as in reception.
The SATELLINE-1870E is an appropriate choice
where price and range are important aspects.
With its high output power, good sensitivity,
small size and low power consumption, it meets
both the technical and economical requirements
set on wireless communications in a number of
applications, including:
• Remote meter reading
(Gas, Electricity, Heat)
Technical Specications SATELLINE-1870E
The equipment complies with the EN 300 220-1, EN 301 489-1 and EN
60950-1 specications.
Values are subject to change without notice.
• Remote control of water distribution
• Remote control of irrigation systems
• Environmental monitoring
