SEE Telecom designs and manufactures UHF Repeaters (BDA – Bi-Directional Amplifiers) :

  • To enhance the radio coverage of national public safety networks ;
  • To extend the coverage of private radio networks in major infrastructures like shopping centers, exhibition halls, convention centers, hospitals, confined areas such as service corridors, tunnels, underground car parks PMR (Private Mobile Radio), DMR (Digital Mobile Radio), LMR (Land Mobile Radio), PAMR (Public-Access Mobile Radio) at TETRA (TErrestrial Trunked RAdio) standard;

This range of products can process any standards in UHF band between 350 and 520 MHz : TETRA, TETRAPOL, EDACS, MPT1327, etc…

Because each installation is unique, SEE Telecom proposes a complete portfolio of solutions with off air and optical repeaters, advanced technologies as band selective, channel selective, AGC per time slot, squelch, frequency shifting, WDM, remote monitoring HTTP-SNMP.
