Satel presents the tiny UHF radio data transceiver module Satelline TR4. The new Satelline TR4 from Satel, a Finnish manufacturer of radio data transmission systems, is a compact UHF transceiver with transmitting power of 1,000 mW. The transceiver is compatible with the protocols of Pacific Crest, Trimble and Satel. The type certifications in important regions of the world make the TR4 ideal for integration in end devices intended for international use. With a weight of only 18 g, transmitting power of 1,000 mW and an “over the air” data transmission rate of 38,400 bps, it fulfills all present-day standards, Satel said. The tiny UHF transceiver is designed for easy integration, with dimensions of 56 x 36 x 6 millimeters, Satel said. Robust UHF frequencies (400-470 MHz) are a reliable basis for the communication of self-sufficient stations even in the event of unknown topology. In addition, the new TR4 features the advantages of the Satelline EASy and 3AS modems, including channel scanning, error correction and compatibility with protocols of Pacific Crest, Trimble and, of course, Satel. Since license-free frequencies are becoming more popular, such as 869 MHz in Europe and 915 MHz for the American market, transceiver modules of identical design will follow. The identical footprint and the standardized communication commands will minimize integration costs. Later it will only be necessary to insert the corresponding radio module for the destination and the end device will be ready to use. In Germany, radio data transmission solutions from Satel are distributed exclusively by the full-range and systems provider Welotec. At INTERGEO in Stuttgart,  September 15 – 17, the partners will present their products at adjacent stands: Satel and Welotec will be in Hall 4 – Booth G4.020.
