1.3.1. Base Station
The WipLL base station provides a radio link between the subscriber and the service
provider's backbone to provide high-speed data access, Internet access, and VoIP.
The WipLL base station equipment consists of a radio transceiver that transmits and
receives signals to and from the subscriber, and of various optional Ethernet hubs
that connect the WipLL transceiver to the service provider’s backbone, through a
100BaseT Ethernet connection.
The WipLL base station is comprised of the following units (see Figure 1-3):
! Base Station Radio (BSR):
The BSR is a radio transceiver that provides the wireless link between the
subscriber and the provider's backbone. Each BSR has 60-degree radio coverage,
serving up to 126 subscribers in that sector.
The BSR is installed outside the base station site, typically mounted on a pole.
! Point-to-Point Radio (PPR):
The PPR device is similar to the BSR, but implemented in a point-to-point radio
configuration providing wireless communication with a single remote WipLL
radio unit (i.e., Subscriber Premises Radio).
