The AirPro Gold platform provide s advanced network management
features using SNMP and HTTP protocols for contr ol and monitoring,
supports remote configur ation by means of BOOT/DHCP (Dynamic
Host Configuration Prot ocol) along with TFTP (Trivial File
Transferring Protocol) for downloading .
AirPro Gold is easy to install and configure. All software controls are
included for network administration. Initial configuration is
implemented via
• a switch bank of twelve DIP switches, or
• a Command Line Interface running on a terminal, or
• the Site Manager a pplic ation r unning on a PC connec ted to the Ai rPro
Gold unit through a local area networ k (LAN) or through the public
telephone network
AirPro Gold offers wide area networ k connec tivity when cables cannot
be used due to distance, physical obstr uctions, or price constr aints. The
wireless network can be dynamica lly reconfigured to provide new
permanent or temporary servic e s . Adding or removing nodes does not
affect network operat ion.
TOPOLOGIES
AirPro Gold lowers networking costs by combining routing and wireless
transceiver func tions in a single unit. It provides remote downloa ding of
firmware and provides password and hard-coded serial number
protected management. The Ethern et 10/100 base-T port connects to the
LAN.
AirPro Gold provides bi-di rectional communication for multiple WAN
nodes. The wireless network can be configur ed to one of three network
topologies:
• Point-to-point—where two nodes are communicating directly with
each other (see s ecti o n Point-to-Point Topology on page 2-1)
• Peer-to-peer—where all nodes in a network communicate directly
with one another (see section Peer-to-Peer Topology on page 2-2)
• Centralized (Star base) —where the node at the center of the network
acts as a switching device for communic ation between remote nodes
(see section Centralized (Star) Topology on page 2-3)

The term network topology refers to the logical layout of a network. It
defines how the network elements will communicate with each other,
how the information will be trans mitted, and how the information will
be routed through the network.
Packet-based networks a re most suitable for networks that invol ve largescale data transmiss ions for multiple users at the same time. There is a
guaranteed minimum throughput for a packet-based network, but the
actual throughput realized by a packet-based network node will depend
on
2
. . . . .
• the number of users in the network, and
• how much traffic is being generated by each node at any given time
The advantage of a packet-based network is that multiple transmissions
can travel along the network at the same time, using whatever path is
appropriate to the routing from the source to the destination.
The most significant characteristic of packet-based networks is the
wireless interface access protocols they use, such as CSMA/CA (Carrier
Sense Multiple Access/Collision Avoidance), which can result in more
efficient use of the aggregate bandwidth by dynamically allocating
throughput to nodes based on demand.

Figure 2-1 Point-to-Point Topology
The range and interference immunity that can be achieved with packetbased point-to-po int topology is maximized by the use of highly
directional antennas on both sides of the link.
In peer-to-peer topology (uni que to pack et-based networks), there are
three or more nodes, any one of which can communicate directly with
any other node. Since each node has direct access to every other node,
the time delay for transferring data between nodes is the least for this
type of topology, unless WAN traffic is very high. However, this also
implies that each node must have a clear communication path to every
other node, that is, there must be clear line of sight.

Figure 2-2 Peer-to-Peer Topolog y
In peer-to-peer topology, since all nodes need to talk to each other, the
range depends on the type of antennas used and the local terr ain. Longer
ranges can be achieved by using directional antennas with power
splitters to connect to a ll sites.
In a Star topology, there is one AirPro Gold at a centr al location
designated as a Base Station or Star Base, and several remotes
designated as Remote Stations or S tar Remotes. The Star Base acts as a
switching device. The Star Remotes communicate with each other
through the Star Base.
An AirPro Gold wireless network with Sta r topology can connect up to
255 wireless nodes. The MAC protocol used combines random and
polling MAC protocols, with positive Data Link acknowledgment that
improves the reliability of frame delivery.
Figure 2-3 on page 2-4 shows AirPro Gold wireless router nodes in a
star topology.

Figure 2-3 Star Topology
A directional antenna can be used for the central site if all of the nodes
fall in the main lobe of the antenna pattern. Since the remote sites need
only communicate with the central site, directional, high gain antennas
can be used.
The range of a Star topology network can be increased if the remote
nodes are all located withi n a confin ed sector from the central site.
Communication between two remote sites must be relayed through the
central node.
Medium access contention on the Star Base is resolved by the specific
Star Base MAC protocol. Each Star Remote sends a data frame only
after it gets permissi on from the Star Base. Each frame transmitted by
Star Base conta ins a PID (polling ID) for the wireless clu ster. If a pol led
Star Remote has a frame to transmit, it explic itly sends the frame to the
Star Base. The St ar Ba se rela ys this fram e to its el f or on to Sta r
Remotes indicated by the DID (destination ID) of the original frame. A
polled Star Remote does not reply to a PID if it has no frame to transmit.
At each wirele ss node, the AirPro Gold® unit connects to a LAN, where
it functions as a wireless remote access router, connecting LANs
through the wireless WAN (wide area network).

making any cable connections, however, you need to properly ground
the unit.
GROUND CONNECTION
The P-Com AirPro Gold unit s hould be gr ounded at the gr ound nu t on the bac k
of the unit before you connect any other cab les. After the unit is grounded,
make sure that any ot her equipment that you connect to the unit is als o
properly grounded.

To conne ct the AirPr o Go l d to the LA N :
1Plug one end of an RJ-45 cable int o the RJ -45 ETHERNET port on the front of
the unit.
2Plug the other end of the RJ-45 cable into the RJ-45 port on the Ethernet Hub.
NOTE
If you are connecting the unit directly to a PC via the RJ-45 port, use a crossover cable (not a straight-through cable), plug one end into the RJ-45 port on

ANTENNA CONNECTION
The type of antenna you use should be a semi-parabolic or solid
parabolic directional antenna. You can purchase the antenna from PCom or its distributors.

NOTE
If the antenna coaxial cable is too stiff to bend easily, add a flexible pigtail
coaxial cable with a coax barrel (available f rom P-Com).

POWER CONNECTION
To connect power to the AirPro Gold unit:
1Plug the AC power cord into the 3-pin connector on the back of the unit. See
Figure 3-6 on page 3-8
2Plug the AC power cord into a grounded electrical outlet.
To avoid electr ical shock or power loss, make sure that the power cord is
securely connected to the unit. Do not use a 3-pole to 2-pole adapter with the
plug. Verify t hat the outlet you use is pr oper ly installed, grounded, and
complies with the loca l electric al code.
3Turn the AC power switch to ON. See Figure 3-6 on page 3-8.
You can configure the P-Com AirPro Gold wireless r outer remotely by
using a telephone modem and the public telephone network. The AirPro
Gold provides an RS-232 port on the front of the unit fo r the modem
connection. See Figure 3-3 on page 3-4.

• RF channel—all units in a common network must use the same RF
channel. Separate WANs in the same geographic area may need to
use different channels (to eliminate interference). AirPro Gold
provides 13 channels.
• Topology—AirPro Gold provides these topologies: peer-to-peer,

• Configuration Reset—to insta ll the basic configuration
You can set up a basic radio configurati on using one of three methods:
• through DIP switch positions
• through a terminal command line interface
• through the Site Manager software application

in the shipping carton.
The rack mounting brackets can be insta lled on the unit chassi s in one of
three positions: front, center, or rear, dependi ng on how you want the
chassis positioned in the rack.
When installing the unit in a rack with other equipment, you must pr ovide 1.75
inches of space above, below, and on each side of the unit to allow proper
ventilation.
For a 19 inch rack, short bracket flanges face the front of the unit. See
