SATELLINE-M3-R4 is a UHF data receiver mod-

ule in a lightweight single board structure. It is

designed to be integrated into a host device, for

instance for receiving GNSS correction data in a

land surveying rover.

It is equipped with all necessary features; such

as 70 MHz tuning range (403...473 MHz) in one

hardware, selectable channel width and low

power consumption. The radio module

conguration can be done with the SATEL

SL-commands or SATEL Conguration

Manager -soware.

SATELLINE-M3-R4 is compatible with other wide-

ly used SATELLINE modules and with

SATELLINE-EASy radio modems, as well as with

other manufacturers’ radio protocols.

SATELLINE-

M3-R4

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 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

Mission-Critical Connectivity

SATELLINE-M3-R4 is a exible

module which makes it a suitable

unit for dierent uses. It is an updated

version of M3-R3 module. It has two

modulations more; 8FSK and 16FSK

which gives more speed to the radio

interface.

SATELLINE-M3-R4 can be added to

existing systems; it is compatible

with widely used SATELLINE-EASy

family radio modems and it

supports also other manufacturers’

radio protocols (such as Pac-Crest-4FSK,

-GMSK, -FST).

The channel bandwidths 12.5 and

25 kHz are soware selectable and

SATELLINE-M3-R4 has a wide 70

MHz tuning range. End-users can

select the operation frequency

within the range of 403...473 MHz.

Technical Specications

SATELLINE-M3-R4 complies with the following international standards:

EN 300 113, EN 301 489-1, -5, EN 60950-1 and FCC Part 90.

The module can be manufactured

with AES128-bit encryption sup-

port on the air interface to ensure

the privacy.

SATELLINE-M3-R4 is supplied with-

out a housing in PCB format with

RF-shielding, facilitating

installation in to the customer’s

own housing or into a host device.

SATELLINE radio modules suit all

kind of needs of OEM customers,

no matter the level of customization.
