PORTAL – the central unit

The PORTAL device is an signal router. It enables formation of radio access network infrastructures in underground conditions. PORTAL can be used as a part of communication systems infrastructure, data transmission, underground identification and localization of the personnel and materials.

PORTAL has got one central unit, PORTAL+ expansion module and battery backup module.
PORTAL enables connection, usage and compatibility with other devices that comprise identification system, such as: RFnode, WireNode, WireNodeIO, Switch OPIS, ExLPS Power supply, MinerSearch, PersonalTAG, Ultra TAG, Ultra TAG-B, TagScaner and network devices: Ethernet or Wi-Fi Ethernet standard.

Main features:

  • 12 hours battery backup
  • ability to connect with 5 main lines of radio node
  • operates with 16 probes of radio gateway
  • built-in Hirschmann switch (optional)
  • AP WiFi AVAYA (optional)
