Hardware Installation
1Placement of the Access Point 2220/2221 – Choose a proper place for your
Access Point 2220/2221. In general, the best location is at the center of your
wireless coverage area, within line of sight of all wireless devices. Try to
place the access point in a position that can best cover its Basic Service Set
(BSS). Normally, the higher you place the access point, the better the
performance. For proper ventilation, allow at least 1 inch (2.54 centimeters)
clearance around the ventilation holes on your Access Point 2220/2221.
(Refer to Appendix B, “Template for placing the Access Point 2220/2221,”

Chapter 2
Network Configuration and Planning
The wireless solution supports a stand-alone wireless network configuration as
well as an integrated configuration with 10/100 Mbps Ethernet LANs.
The wireless network cards, adapters, access points and wireless access point can
be configured as:
• Ad hoc for departmental LANs
• Infrastructure for wireless LANs
• Infrastructure wireless LAN for roaming wireless PCs
Network Topologies
Ad Hoc Wireless LAN
(no AP or Bridge)
Ad-hoc mode is also called “peer-to-peer
mode” or “Independent Basic Service Set
(IBSS).” In ad hoc mode, devices
communicate directly with each other
without using an access point.
An ad hoc wireless LAN consists of a group
of computers, each equipped with a wireless
adapter, connected via radio signals as an
independent wireless LAN. Computers in a
specific ad hoc wireless LAN must therefore be configured to the same radio
channel. An ad hoc wireless LAN can be used for a branch office operation.

Infrastructure Wireless LAN
The access point can also provide access to a wired LAN for wireless
workstations. An integrated wired/wireless LAN is called an Infrastructure
configuration. A Basic Service Set (BSS) consists of a group of wireless PC users,
and an access point that is directly connected to the wired LAN. Each wireless PC
in this BSS can talk to any computer in its wireless group via a radio link, or
access other computers or network resources in the wired LAN infrastructure via
the access point.
The infrastructure configuration not only extends the accessibility of wireless PCs
to the wired LAN, but also increases the effective wireless transmission range for
wireless PCs by passing their signal through one or more access points.
A wireless infrastructure can be used for access to a central database, or for
connection between mobile workers, as shown in the following figure.
Infrastructure Wireless LAN for Roaming Wireless PCs
The Basic Service Set (BSS) is the communications domain for each wireless
access point. For wireless PCs that do not need to support roaming, set the domain
identifier (SSID) for the wireless card to the SSID of the access point to which
you want to connect. Check with your administrator for the SSID of the access
point or bridge to which he wants you to connect.

A wireless infrastructure can also support roaming for mobile workers. More than
one access point can be configured to create an Extended Service Set (ESS). By
placing the access points so that a continuous coverage area is created, wireless
users within this ESS can roam freely. All Nortel Networks Wireless LAN--Series
2200 wireless network cards and adapters and Access Point 2220/2221 wireless
access points within a specific ESS must be configured with the same SSID
.

Maximum Station Data Rate
Select the appropriate data rate from the drop-down list for the data transfer speed
running on your network. (Default: 11 Mbps)
Beacon Interval (20-1000)
Sets the beacon signal interval. The beacon signals allow the wireless devices to
maintain contact with each other. They may also carry power-management
information. (Default: 100 TU)
DTIM Period (1-16384)
Sets the Delivery Traffic Indication Message (DTIM) packet interval value. The
DTIM informs the client that the access point has broadcast and multicast traffic
to send. This parameter is necessary to wake up stations that are using Power Save
mode.
Note: The available channel settings are limited by local regulations,
which determine the number of channels that are available. (For more
information specific to each country’s configuration, refer to
Country-specific Configuration for the Nortel Networks Wireless LAN

![](/img.php?id=342106&img=bg2f.png)
Chapter 3 System Configuration 47
Using the Nortel Networks Wireless LAN Access Point 2220/2221
The DTIM is the interval between two synchronous frames with broadcast
information. If you set the value to 2, the access point saves broadcast and
multicast packets and forwards them after every second beacon. Having smaller
DTIM intervals delivers broadcast and multicast frames in a more timely manner;
however, by causing stations in Power Save mode to wake up more often, smaller
DTIM intervals drain power faster. Conversely, having higher DTIM values delays
the transmission of broadcast and multicast frames, but the larger DTIM intervals
reduces the power used by stations in Power Save mode. (Default: 5 Beacons)
RTS Threshold (0-2347)
Set the RTS (Request to Send) frame length. You may configure the access point
to initiate an RTS frame sequence always, never, or only on frames longer than a
specified length. If the packet size is smaller than the preset RTS threshold size,
the RTS/CTS mechanism will NOT be enabled
When the RTS/CTS mechanism is enabled, the access point sends Request to
Send (RTS) frames to a particular receiving station to negotiate the sending of a
data frame. After receiving an RTS frame, the station sends a CTS (Clear to Send)
frame to acknowledge the right of the sending station to send data frames. The
access points contending for the media may not be aware of each other. The RTS/
CTS mechanism allows other access points in the vicinity to see the CTS and
become quiet while the first access point transmits frames. (This mechanism
should be enabled on both the clients and the access points.) (Default: 2347)
Preamble Setting
The access points and client card drivers have a radio setting for RF Preamble. Set
it to short for better throughput; although this setting may cause interoperability
issues with some NICs. (Default: Long)
