INTRODUCTION
1.3.6 The Wireless Hub
The wireless hub provides connectivity within an 80 meter or 263
foot radius in a typical in-building ofÞce environment with
wallboard and steel stud construction. The wireless hub
communicates with the FreeLINK Wireless Transceiver using
spread spectrum radio technology. The wireless hub maintains a
list of serial numbers of the wireless transceivers located within its
LAN, and will deny access to any transceiver whose serial number
it does not recognize.
The wireless hub will accept up to 62 wireless transceivers. The
wireless hub provides transparent compatibility with existing
802.3 Ethernet networks. The hub also synchronizes all of the
wireless transceivers within the wireless LAN to maximize data
throughput.
The hub remotely controls power levels for the transceivers to
compensate for near/far transmission signal levels. The wireless
hub consists of the main chassis and an antenna assembly
connected by a cable. Within the main chassis are a ßoppy disk
drive, a switch-selectable RJ-45 port and AUI port, and an RS232
port for connection to a modem.
1.3.7 The Wireless Transceiver/Interface Units
You can connect any Ethernet device to the wireless system via the
IEEE 802.3-compatible FreeLINK Wireless Transceiver/Interface
Units. Wireless Transceiver/Interface Units are available in two
conÞgurations; single port, and multi-port. The FreeLINK Single
Port Interface Unit (FLIU-1) contains a single RJ-45 connector, and
an AUI connector for access to an Ethernet device, or to the
Ethernet network. The Wireless Multi-Port Interface Unit (FLIU-8),
contains eight RJ-45 ports only.
