The digital remote unit - the idRU - is an IP65, outdoor as well as indoor, four-band remote unit, where two units can be cascaded through a CPRI link to support eight bands. Each band can provide medium-power of 30dBm per band or high-power of 40dBm per band. The Remote Units serve as the backhaul port of any IP device or switch in the neighbourhood; thus, it distributes combined cellular and data services according to user defined configuration profiles. The idRU is connected to the MSDH via 10 Gbit/s CPRI interfaces, where each interface contains an embedded 1Gbit/s IP backhaul link.
