1.3.2. Indoor Radio Only
The indoor radio unit configuration consists solely of the ASWipLL Indoor Data
Radio (IDR). The IDR combines the functionality of the SPR and SDA, functioning
both as a transceiver and a hub. The IDR provides one 10BaseT Ethernet interface
with the subscriber's network. The IDR receives its power from a separate power
supply adapter (AC/DC or DC/DC power adapter).
The IDR is available in various models. These models differ mainly by:
 Antenna design (providing integral flat-panel antennas, or TNC-type ports for
attaching third-party external antennas)
 Antenna gain
 Frequency band in which they are configured to operate
The IDR model with an integral flat-panel antenna is typically mounted on an
interior wall or on a desktop, ensuring line-of-sight with the Base Station. The IDR
model with a third-party external antenna is also mounted indoors, but the external
antenna is typically mounted outdoors to provide line-of-sight 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 1-3
displays a typical setup for data and voice at a subscriber site implementing the IDR.
