1.3.2. Subscriber Site
The WipLL subscriber site is located at the service provider's subscribers’ premises.
The WipLL subscriber site equipment consists of a radio transceiver that receives
and transmits signals from and to the base station. The WipLL radio transceiver
provides the subscriber with high-speed data access, Internet access, and VoIP at up
to 3.2 Mbps. The WipLL transceiver connects to the subscriber’s network or PC via
WipLL’s Ethernet hub (i.e., Subscriber Data Adapter).
The WipLL system can group subscribers into VLANs, as well as assign MIR and
CIR levels to each subscriber, guaranteeing bandwidth to subscribers.
The WipLL subscriber site is comprised of the following units:
! Subscriber Premises Radio (SPR):
The SPR is a radio transceiver that provides a wireless link between the base
station and the subscriber’s network. The SPR is installed outside the
subscriber's premises, typically on a roof.
! Subscriber Data Adapter (SDA):
The SDA is a hub/switch that provides the SPR with -48 VDC power supply and
Ethernet connectivity to the subscriber’s network/PC. The SDA is installed
inside the subscriber's premises and is connected to the SPR by a CAT-5 cable.
The SDA models include the following:
! SDA-1: provides one 10BaseT connection to the subscriber’s computer
and/or network.
! SDA-4H: provides a hub and four 10BaseT interfaces to the subscriber’s
computers and/or networks. The hub interface is a crossed Ethernet cable that
can connect to another hub or LAN switch. Alternatively, it may be
connected to another PC via a crossed Ethernet cable.
