1.4.2. Indoor Radio Unit (IDR) Only
The indoor radio unit configuration consists of the ASWipLL Indoor Data Radio
(IDR). The IDR combines the functionality of the SPR and SDA, functioning as a
transceiver and a hub. The IDR provides one 10BaseT Ethernet interface to the
subscriber's network. The IDR receives its power from a separate power supply unit
(AC-DC power adapter).
The IDR with a built-in antenna is typically mounted on an interior wall or on a
desktop with line-of-site with the Base Station. The antenna of the IDR model with
an external antenna is typically mounted outdoors to provide line-of-site with the
Base Station.
The IDR can be used for data and voice transmissions. In the case of voice, the IDR
uses a third-party RGW to interface with the subscriber's IP phone. Figure 1-4
displays a typical setup for data and voice at a subscriber site implementing the IDR.
