) or licensed frequency bands (UHF, VHF).
The operation range of a radio modem varies depending on the transmission power, antenna gain and mast height, and environment. In rural areas a 1 W radio modem with a line-of-sight
radio link may range over 20 km and even up to 50 km in exceptionally amicable environments. In dense metropolitan areas, a corresponding range may vary from several kilometers to over 10 km. With a 10 W radio modem, a range of up to 80 km can be reached in favorable environments. By using radio modem repeaters, much broader areas can be covered.

, RS-485, RS-422). This product family has proven its reliability over the years in applications ranging from Mt Everest to power distribution networks and from professional motor sports to runway telemetry at airports.
The SATELLAR Digital System radio modem family, which was introduced in November 2008, broadened the offering to TCP/IP based applications. It is based on a Linux
operating systems and enables customer specific applications.
SATELLINE-1915 is a similar radio modem, which employs frequency hopping and spread spectrum technologies. The compact, versatile radio modem operates in the 902 - 928 MHz band, and can thus be used in the license free bands of Australia and many countries in North and South America.
Radio modems are available for both the UHF (360 - 470 MHz) and VHF (135 - 174 MHz and 218 - 238 MHz) frequency bands. The modem series SATELLINE-3AS(d) VHF is specifically designed for data applications, where large distances with obstacles such as Mountains and valleys are to be spanned.
Different channel widths (12.5 / 20 / 25 kHz) and data rates (9.600 / 19.200 bps) are available in order to meet both the needs of the system and the requirements of the local authorities. The transmit power is adjustable between 100 mW and 1 W. In addition, radio modems with 1W, 10W and 35W transmitter power are available. This allows transmission distances of up to several tens of kilometers, depending on the environment and the used antenna type. Typical applications include machine control, utility distribution networks, water facilities, precision farming and land surveying.

About the Company
SATEL specializes in designing and manufacturing radio modems for long range wireless data transmission. The company was founded in 1986. SATEL’s first product was a wrist alarm, shortly followed by production of the first radio modem. Product development has been guided by emphasizing RF sensitivity and ensuring reliability and durability.Both SATEL's product development and factory are located in Finland. The distribution network of SATEL covers over 100 countries. Approx 90% of sales is exported.
Radio modems in general
A radio modem transmits data over a wireless connection to another radio modem over a point-to-point or -multipoint link. Radio modems are independent of mobile and satellite network operators and no cost is thus associated with transferring data. Private radio modem networks can use either unlicensed (e.g. ISM bandISM band

Setup made easy with license-free products
For wireless data transfer needs over a few kilometers, SATELLINE-1870E is a straightforward solution. This radio modem operates in the Europe-wide license-free 868 - 870 MHz band and has a maximum transmit power 500 mW, which enables coverage up to 2.5 km. By setting up a network with repeater radio modems, much longer distances can be achieved. The radio modem can accommodate point-to-point as well as point-to-multipoint communications.SATELLINE-1915 is a similar radio modem, which employs frequency hopping and spread spectrum technologies. The compact, versatile radio modem operates in the 902 - 928 MHz band, and can thus be used in the license free bands of Australia and many countries in North and South America.
Higher power – longer range
The radio modems of the SATELLINE-3AS -family are suitable for high-end applications requiring a longer range. With these radio modems, a reliable radio modem network can be built across vast areas.Radio modems are available for both the UHF (360 - 470 MHz) and VHF (135 - 174 MHz and 218 - 238 MHz) frequency bands. The modem series SATELLINE-3AS(d) VHF is specifically designed for data applications, where large distances with obstacles such as Mountains and valleys are to be spanned.
