10.1. Overview
The IDR device is an optional WipLL device that combines the functionality of the
SPR and SDA devices. The IDR has a built-in antenna that provides an interface for
transmission with the base station. In addition, the IDR provides an interface for
10Base-T Ethernet with the subscriber's network. However, unlike the SDA, a
separate power supply unit (power adapter) powers the IDR.
The IDR is available in two models:
! IDR with an internal antenna
! IDR with a TNC connector for connecting to a third-party external antenna
