Terminal Unit (TU)
The Terminal Unit (TU) supports voice and data communications in a land mobile or terrestrial
fixed environment. The TU is capable of supporting wireless voice and data that links the user
with the Iridium satellite network. The TU, depending on Line of Site (LOS) and Low Earth
Orbiting (LEO) Satellites, will be able to maintain satellite connectivity while experiencing
conditions varying from urban canyons to high vibration from road movement. As a wireless
access point, the TU provides Wi-Fi (802.11) access for data and Voice over IP (VoIP) calls.
Three RJ-45 Ethernet connectors and one RJ14 connector enables the user to tether directly to
the TU, if desired. The Management Portal is a graphical user interface that can be used to
modify system settings and indicate system status. The TU is powered by either a DC power
cable with a 10-32V input range and remote start wire or an AC/DC power supply,
accommodating all types of vehicles, applications and power sources.

NOTE
Wi-Fi Access Point:
The internal Wi-Fi access point is not a high capacity Wi-Fi system.
If heavy simultaneous data usage is expected through Wi-Fi, it may
be best to use an external commercial Wi-Fi router connected to the
BDU’s LAN port.
