WipLL’s subscriber site equipment is comprised of the following:
! 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.
! SDA-4S models: integrated LAN switches, providing four Auto Negotiation
10/100BaseT (Full or Half Duplex mode) ports for interfacing with the
subscriber’s PCs/network) These models include the following:
− SDA-4S (standard): Standard integrated LAN switch, providing four
10/100BaseT interfaces to the subscriber’s computers. This model is
ideal for SOHO implementation.
− SDA-4S/VL: Provides VLANs between its ports and the SPR, ensuring
privacy between users of different ports. For example, all users connected
to Port 1 do not “see” users connected to Port 2. This model is ideal for
multi-tenant implementation.
