The SMT-I3 Wireless to USB device serves as the interface between Data Acquisition Units and the Building Intelligence Gateway (BiG).
 
Wireless data acquisition units communicate sensor readings to the Building Intelligence Gateway through an I3 interface. An I3 unit will automatically become a repeater when powered. If require, wired extensions can be used to relocate I3 units in areas where wireless coverage is intermittent or difficult to reach.
