It has two RF connectors, one connected to the donor antenna pointing toward the base station and the second one is connected to the service antennas or radiating cable in tunnel or building. It also enables on-the-fly filter change/upgrade by software without an expensive hardware upgrade. This achieves high out of-band rejection and high intra-Carrier interference compared to traditional Analog IF SAW filters. The HELIOS® Digital TETRA / TETRAPOL Off-Air Repeaters employ Software Defined Radio (SDR) technology based upon our FPGA & DSP Platform.
Our products meet all the regulatory standards and specifications, such as national public safety and technical requirements. All of HELIOS® public safety digital repeaters are easy to install and are operated and controlled by SNMP, SCADA or Ethernet using a web browser.Īlso, we produce digital TETRA repeaters that are customizable to the client’s needs and different state legislations, and they can process any frequencies due to advantage of SDR technique. HELIOS® Technologies’ compact size and multi-channel digital repeater enhances RF coverage in confined areas to enhance the public safety networks or private radio networks with large coverage capability and no near-far effect. HELIOS® Technologies provides digital TETRA repeaters that are homologated to enhance public safety networks and private radio networks. HELIOS® Technologies’ indoor coverage solutions can meet all the requirements of any individual public safety network or private radio network. Our public safety digital repeaters (BDA) can be successfully installed and used all around the globe, as our know-how lets us produce digital repeaters of all dimensions and technical features. With NET, digital radio professionals receive exactly the right tool for their needs.Because each installation/project is unique, HELIOS® Technologies proposes a complete portfolio of solutions with digital off-air and optical repeaters, advanced DSP (Digital Signal Processing) technologies as band selective, channel selective, AGC per time slot, squelch, frequency shifting, CPRI transportation, remote monitoring via HTTP-SNMP. NET also feeds PDU output data to ORANGE for visually displaying and comparing call and data message statistics. Software package, making drive testing incredibly simple. , but without the additional analog demodulation and other features not applicable to the digital radio protocols. Gives operators they same analytical power of Decodio NET is a tailored version of our RED software offering only single digital radio protocol decoding, extremely useful for Network Operators specializing in TERTA, TETRAPOL, P25, and DMR systems.
