1 Overview
4 Installation and User Guide: Airgo Access Point
Radio Resource Management
The Airgo AP supports management of radio channels, cell size, and range.
Channel management features include automatic channel selection, support for international
channel sets, dynamic channel changes in response to network conditions, and the ability to assign
channels manually to fine tune channel quality. Cell size and range capabilities enable you to
optimize equipment placement, eliminate dead spots, and reduce interference.
Mobility Management
Mobility management features include Layer-2 and Layer-3 roaming, as users move from one
access point coverage area to another or are switched for load balancing purposes. Layer-2 roaming
occurs by default when a wireless client roams between APs on the same subnet, if 802.11f-based
Inter-Access Point Protocol (IAPP) is enabled. The Layer-3 Mobility feature provides seamless
roaming for wireless clients across multiple subnets in proximity to each other.
Portal Architecture
To support the range of network sizes and configurations served by Airgo Networks products,
Airgo has designed a built-in, flexible, portal services architecture for management and security.
An AP can be configured as an NM Portal AP to support the following services:
Figure 2 illustrates portal services within the Airgo Networks network. NM Portal provides overall
network management functionality and monitoring. The enrollment portal feature enables
verification of additional APs and authorization for operation in the network. The security portal
feature verifies the identity of individual users wanting access to the network.
Service Description
Management NM Portal services provide network management functionality for small to
mid-size wireless networks. Each Airgo AP configured as an NM Portal can
operate in stand-alone mode to provide network management for the entire
network or as a location or branch manager working in conjunction with NMS
Pro, the Airgo Networks Professional Network Management System.
Security Security portal services include support for secure user authentication by way
of a RADIUS server internal to the Airgo AP. Security portal services are part
of NM Portal, but can also be configured independently for backup
authentication in the event that the primary internal RADIUS server becomes
unavailable.
Enrollment Each Airgo Networks wireless network requires an enrollment server to verify
the identity other of Airgo APs and authorize them for operation in the
network. The enrollment portal feature is automatically enabled in the access
point as part of NM Portal. NM Portal should be used for enrollment unless
NMS Pro has been implemented as an enterprise network management
solution.
Features Overview
Installation and User Guide: Airgo Access Point 5
Figure 2: Portal Services
Regardless of network size, configuring one or more Airgo APs as NM Portals yields the following
benefits:
•Even with as few as two APs in a network, NM Portal offers a single point of focus for
monitoring the network and managing security. Configuring the first installed AP as an NM
Portal makes it easy to enroll additional APs.
•The configuration of the NM Portal AP is easily distributed to the other APs in the network,
assuring consistent application of configuration parameters.
•NM Portal can provide user authentication services for an entire small to mid-size network or
serve as a backup security server if an external RADIUS authentication service is used.
Security
Airgo Networks offers a comprehensive security solution that adheres to the following industry
standards and draft standards:
•Data encryption — WEP, Wi-Fi Protected Access (WPA) with TKIP or AES encryption
•User authentication — IEEE 802.1x authentication, including EAP-PEAP or EAP-TLS, WPA-
PSK
•Key management — Microsoft-IAS, FUNK-RADIUS, Airgo Networks NMS Pro, Airgo
Networks integrated security portal, and manual key management capabilities
These features are part of a security architecture that provides the wireless network a greater degree
of security than most traditional wired networks. The following security features are included in all
Airgo Access Points:
•Built-in maximum industry-standard security
•Auto-detection of the security capability of clients and APs
•Policy-based configuration of security settings
•Hardware support for high-performance encryption
•Support for installations ranging from the small-office/home-office (SOHO) to multi-site
enterprises

VLANs
By decoupling traffic flow and network services from the physical network topology, virtual LANs
(VLANs) enable enterprises to improve network traffic flow, increase load, and deliver varying
levels of service and access to different groups of users. The Airgo AP VLAN feature readily
extends an existing wired VLAN structure to the wireless network. It can also be used to implement
new network privileges and services; for example, user VLANs are integral to the Airgo Networks
guest access feature (see “Guest Access” on page 7).
Airgo supports interface-based VLANs and user-based VLANs. Interface VLANs separate traffic
according to the Ethernet and radio interfaces on the Airgo AP. Packets destined for a specific
interface VLAN are directed to the port with that VLAN assigned. By contrast, user VLANs
separate traffic according to user groups. Users can be assigned to the same VLAN even if they are
in different physical LANs and at geographically dispersed locations. User VLANs are useful for
managing enterprise work groups and differentiating among categories of users. The Airgo Access
Point supports up to 16 VLANs, including a default VLAN.
Quality of Service
Quality of Service (QoS) features enable differential treatment of network traffic types to support
special applications or extend priority access to designated groups of users. For example,
applications such as streaming media and voice over IP (VoIP) suffer serious quality degradation if
data transmission is interrupted or bandwidth fluctuates excessively. You can assign higher service
quality to applications of this type, while maintaining adequate service for less intensive
applications such as print and file sharing. Network utilization is increased with little to no negative
effect on user productivity. QoS can also be used to lower the priority for non-critical applications.
For example, FTP transfers, which are generally not time critical but can consume significant
network bandwidth, can be assigned lower priority than streaming media applications or database
transactions.
QoS can also be assigned on a user group basis. For example, network administrators can be
assigned a higher service quality than other employees, thereby enhancing their ability to manage
and troubleshoot a heavily loaded network.
Airgo Networks implements QoS features using classes of service (COS). Eight COS levels are
available for assignment according to user, group, or application based rules. The COS approach
does not guarantee bandwidth, but it does give “best effort” priority according to the assigned level.
A flexible approach to service quality, it scales easily and accommodates a variety of mapping
rules. MAC layer mappings for COS levels and COS-to-IP layer mappings are supported, and
priority settings can be assigned for different COS mapping rules.
IP Routing
IP routing adds flexibility to AP management and expands the addressing capability of the AP. You
can specify static IP addresses outside the local subnet along with routing information to reach
those addresses.
Standards and Data Rates
Installation and User Guide: Airgo Access Point 7
Multiple SSIDs
The Airgo AP supports multiple SSIDs within each individual AP. Using the multiple SSID
feature, users can access separate networks through a single physical infrastructure. For example, if
you want to create different levels of resource access for employees and visitors, you can create two
SSIDs, one with high security and one with open security.
Guest Access
The Airgo AP supports flexible, secure management of guest access at corporate and hot spot
locations. By contrast with most other guest access solutions, the Airgo AP supports guest access
without necessarily requiring changes to the physical network topology. VLAN tags on the existing
access points segregate users into non-guest and guest VLANs, and guests are automatically
directed to an internal or external web landing page. Guest passwords can be assigned statically or
change dynamically according to a pre-set schedule. An open access option is available to provide
unauthenticated guests with access to an open subnet.
Rogue AP Detection and Classification
Maintaining a secure wireless network requires ongoing monitoring of potential rogue access
points and the ability to classify them as known to the local or neighboring network, or as true
rogues. The network management functions of NM Portal include automatic network scanning and
display of detected APs that potentially qualify as rogues. Using the information included in the
display, network administrators can identify and classify the known APs. The remaining APs are
classified as rogues. By examining the information available for each rogue AP, it is generally
possible to pinpoint the location of the rogue and take action to remove it from the network.
Standards and Data Rates
Airgo Networks supports the wireless networking standards shown in Table 2.

2Planning Your Installation
This chapter provides guidelines on planning a wireless network. It includes example network
configurations and explains how to plan for coverage, capacity, security, and network management.
The chapter includes the following topics:
•Introduction
•Assessing Coverage and Capacity Requirements
•Assessing Security Needs and Architecture
•Planning Network Features
•Sample Deployment Scenarios
Introduction
Careful planning of a new wireless network can greatly enhance your ability to install, maintain,
manage, and expand the network. There are several dimensions to installation planning:
•Coverage and capacity requirements — Identify the number and types of access points to
install and determine optimal placement.
•Security needs — Choose a security architecture and features.
•Network management — Choose a method to manage the network and monitor its health.
•Network features — Determine VLAN assignment, user groups, services, and privileges.
If planned properly, a wireless network can be easily expanded and adjusted to changing conditions
and requirements while preserving effective security and enabling network-wide management
support.
Example Wireless Network Installation
Figure 3 shows the elements of a typical Airgo wireless network. Airgo Access Points provide
wireless connectivity to client stations (laptop or desktop computers) and connect in turn to the
existing wired network infrastructure and beyond to the Internet. Network size and complexity may
also dictate the need for an external RADIUS server for user authentication, as well as installation
of Airgo Networks NMS Pro for enterprise network management.

Figure 3: Typical Wireless Network
Assessing Coverage and Capacity Requirements
Airgo Networks wireless technology significantly increases wireless coverage or capacity in
comparison to other wireless LAN products. This wireless advantage allows an access point to
service a large area or provide higher data rates, depending upon the conditions at your location.
Figure 4 illustrates the contrast between typical wireless coverage and Airgo wireless coverage.
Each Airgo AP can service a wider area or provide higher data rates than alternative solutions.
Precise coverage and capacity vary considerably depending on factors such as the specific 802.11
protocol being used, antenna placement and location, building construction materials, and local
obstructions.

Figure 4: Airgo AP Coverage Compared with Other Access Points
Site Surveys
Site surveys are used to measure the wireless characteristics of the physical environment and
thereby determine cost-efficient placement of equipment in the network. They are useful because
physical attributes of a location may have a significant impact on realized coverage and data rates.
The site survey involves a detailed assessment of the radio signal environment of the site based on
experiments and testing. After the wireless network equipment is installed, radio signals are sent
between the AP and a mobile client (laptop) to effectively tune the placement of APs.
A professional site survey is highly recommended for large installations, but can be an expensive
and time-consuming process, especially for installations with a variety of buildings and building
materials, radio signal conditions, and restrictions on equipment placement. Thanks to the dramatic
improvements in capacity and coverage provided by Airgo APs, many small to mid-size companies
can forgo the traditional site survey process and rely instead on general guidelines.
Assessing Security Needs and Architecture
The latest security innovations and standards make it possible to provide complete and effective
security for wireless networks. The specifics of an optimal security solution will vary according to
the type and size of organization. For each environment, Airgo offers a selection of features to
satisfy all your security needs.
Three aspects of security require planning and decisions:
•Enrollment — Specifying the Airgo AP or NMS Pro server used to verify which access points
are authorized to be part of the wireless network.

•Data encryption — Specifying the method of security for wireless data communications
between client stations and the AP.
•Authentication — Specifying the method to verify the identity of users who want to access the
wireless network, and assign access restrictions and services to them.
Enrollment
Enrollment is the process of verifying the identity of APs and confirming that they are authorized to
be a legitimate part of the wireless network. It is recommended that you designate a single
enrollment server for the entire network. For small and mid-size networks, this should be an AP
configured as an NM Portal (see “Selecting a Network Management Method” on page 12). For
large offices and campuses, it is recommended that you use the enrollment module within NMS Pro
as the enrollment server. The process of enrollment is discussed in “Enrolling APs” on page 181.
Data Encryption
Data encryption is the process whereby data packets are encoded to prevent intruders from
deciphering the content. The first wave of IEEE 802.11 products introduced encryption based on
the Wired Equivalent Privacy (WEP) standard. The WEP algorithm uses keys configured on the AP
and in the user client software to encrypt wireless data. Unfortunately, WEP is vulnerable to
compromise and difficult to manage and configure. Temporal Key Integrity Protocol (TKIP) is the
secure successor to WEP.
The current state of the art for data encryption is the Advanced Encryption Standard (AES),
adopted by the Wi-Fi Alliance as part of the IEEE 802.11i working group under the heading Wi-Fi
Protected Access (WPA). The new IEEE 802.11i standard provides financial-grade security with
extremely strong AES over-the-air encryption. The keys used for every user session are unique and
are established automatically using the IEEE 802.1x protocol.
Unless your wireless network must support WEP encryption, using WPA with AES for data
encryption, regardless of your network size or complexity, is recommended.
User Authentication
User authentication is the process of verifying user identity and assigning access rights based on
predetermined rules.
•For small to mid-size networks, the internal RADIUS server within the Airgo AP security
portal provides authentication services across the network. A second AP can also be configured
as a backup security portal.
•For large office and campus installations, one or more external RADIUS authentication servers
may already be in place to provide authentication services for the wired network based on the
IEEE 802.1x RADIUS standard. It is a straightforward exercise to extend that infrastructure to
the wireless network, thereby creating an integrated user authentication process for the entire
enterprise network.
The security portal feature of the Airgo AP plays a special role in wireless backhaul authentication.
For more information, see Chapter 6, “Configuring a Wireless Backhaul.”
Selecting a Network Management Method
As with user authentication, appropriate network management solutions depend upon the size and
complexity of the network, and Airgo products and features are available to support a wide range of
possibilities.
Assessing Security Needs and Architecture
Installation and User Guide: Airgo Access Point 13
•For small and mid-sized networks, configure one of the APs on the network as a portal AP to
provide NM Portal, security portal, and enrollment services, and designate another AP as a
backup for the security portal.
•For large offices and campuses, enterprise-wide control and advanced network management
features become essential to reliable network operations. For these networks, the Airgo NMS
Pro network management application is recommended as a comprehensive network
management solution. Install the NMS server on any suitably configured network computer,
and permit network administrators to obtain access from any designated client station. For
more information, see the Airgo Networks NMS Pro Installation and Configuration Guide.
NMS can be installed as a stand-alone network management solution, or it can be used in
conjunction with NM Portal APs to create an efficient distribution system for network management
data and policies across multiple locations. In enterprises with multiple locations, assign an AP in
each location as the NM Portal. The NM Portal serves an auxiliary function, executing commands
for AP management updates and distributing them to all the APs at the remote location or
collecting data from all the APs at the location and sending the data back to NMS Pro. This model
can significantly reduce the time and network load associated with performing network
management functions such as policy distribution and software updates.

Planning Network Features
The Airgo AP offers an extensive set of configuration parameters and network service features.
Automated and default options are available for most of these, making it necessary to configure
only a few of the AP parameters to set up a basic network. As needs change, additional features can
be configured to support new network services.
Network feature planning involves the following decisions:
Feature Planning Issues
Physical
Network
Estimate how many APs are expected initially and with growth. Determine whether
wireless backhaul will be required.
Network
Management
Determine the network management structure.
•A network management solution such as NM Portal or NMS Pro is strongly
recommended for all multiple AP installations.
•NM Portal is recommended for small to mid-size networks.
•NMS Pro is recommended for large enterprise networks. NMS Pro can be used in
conjunction with NM Portal for an efficient, hierarchical network management
solution.
•If wireless backhaul is selected, then network management must include NM
Portal.
Authentication Determine how to verify the identity of users requesting access to the network. An
authentication scheme is required for all except open access.
• Pre-shared key (PSK) authentication uses matching keys assigned prior to the
authentication session and stored on the AP and in the client. With PSK, no external
authentication server is required. This approach is useful for small to mid-size
networks in which keys can be easily configured and modified, as needed.
• RADIUS user authentication relies upon individual login and password. This
approach is preferred for medium-large and enterprise networks that must
accommodate sizable, changing user populations. RADIUS is the most common
protocol used in authentication servers.
The Airgo AP can take advantage of the authentication services provided by an
external third party RADIUS server or the internal RADIUS security portal on the
Airgo AP. In conjunction with an external RADIUS server, the security portal
provides wireless backhaul authentication services and can serve as a backup
authentication server if the external RADIUS server is not available.
An authentication zone is a group of one or more RADIUS servers providing user
authentication services within an SSID. If multiple SSIDs are configured, then you
can create an authentication zone for each.
The chosen authentication method influences how services can be configured in the
network.
Security Modes Choose WPA, WEP, or open security modes.
•WPA is recommended, unless WEP is required for communication with legacy
systems.
•WPA security is compatible with WEP and with open security. WEP is not
compatible with open security.
•Guest access requires the open security mode.
•The preferred encryption method is AES, unless TKIP or WEP are required for
compatibility with legacy systems.
Planning Network Features
Installation and User Guide: Airgo Access Point 15
VLAN VLANs permit the network to be segmented according to functional needs without the
restrictions of the physical topology.
•If your enterprise uses multiple VLANS, they can be supported in the wireless
network.
•Multiple VLANs are required for guest access.
SSID Decide whether one or multiple SSIDs will be supported.
•Multiple SSIDs are desirable for applications such as wireless Internet service
(WISP), in which a single physical access point supports multiple user populations
in distinct networks.
•Multiple SSIDs permit support of multiple service levels in networks that rely on
PSK rather than user-based authentication. Services are bound to the SSID rather
than to specific user groups.
Quality of
Service
Quality of Service (QoS) allows you to set priorities for user traffic, thereby increasing
the likelihood that critical data will obtain the needed priority.
•QoS is implemented by way of class of service (COS) mappings. Accept the default
mappings or define custom mappings to create special high or low priority classes
of service.
•Default and custom mappings are compatible with other feature selections.
Service Profile Service profiles specify the services available for an SSID or for designated user
groups within an SSID.
•Accept the default service profile or create custom service profiles to provide
varying levels of service.
•The service profile includes VLAN assignment, COS, and minimum security.
Once created, a service profile can be bound to an SSID with or without a specified
user group.
•If a user group is included in the binding of a service profile to an SSID, then
members of the user group are automatically assigned that profile when
authenticated.
•If no user groups are specified, then all users who access the SSID are assigned the
same profile.
Guest Access Guest access refers to special treatment of users who are not authorized to access the
main corporate network. The guest access feature allows non-authorized users to gain
network access in a controlled way.
Decide whether the network will support guest users and if so, how guest access will
be managed.
•Guest access requires open access security and is not compatible with WEP.
•Guest users can be authenticated by way of an internal or external web landing
page, or can be given open access to a restricted portion of the corporate network.

Sample Deployment Scenarios
This section describes sample feature decisions for companies as a function of network size,
management structure, and network services.
Example 1: Small office, single AP, possible future growth
Acme Works begins as a small company with 20 users. The office is at a single location served by
one access point connected to the wired backbone. The elements of the network are shown in
Figure 5.
Figure 5: Example 1 Network
One AP is able to meet current coverage and capacity needs. The AP is configured as an NM Portal
to assure that the appropriate network management structure will be in place in the event that the
business expands and additional APs are required. Since the user base is small, there is no need for
a RADIUS authentication infrastructure. The security mode is WPA with pre-shared keys (PSK)
and AES encryption. A single SSID is in place, and the default VLAN, QoS, and service profiles
are used.

Example 3: Mid-size business, multiple SSIDs, multiple VLANs
Now a successful business, the management at Acme Works wants to position the company for
continued growth. Management decides to deploy an external RADIUS server to manage user
authentication centrally for the entire company. The RADIUS authentication infrastructure works
well for a changing user population (employees joining, leaving, or moving to new departments)
and readily supports further network service enhancements.
The company creates two SSIDs as a way to separate the Finance department network traffic from
the main corporate network traffic. Two RADIUS servers are configured, each in its own
authentication zone. To separate Finance department traffic from the overall network traffic, a
Finance VLAN is created. A Finance service profile is also created and bound to the Finance SSID.
The service profile is configured to include the Finance VLAN, high security, and higher-than-
normal COS. Once this structure is in place and a member of the Finance group is authenticated by
way of the RADIUS server, the Finance group tag is passed to the Airgo AP, and the Finance
service profile is applied to the user.
The network configuration for this example is shown in Figure 9, and the feature decisions are
shown in Figure 10.

Example 4: Large business, guest access, extended network services
Acme Works is now a widely known and successful enterprise. With an ever increasing number of
visitors requiring network access, the network administrator decides to implement a corporate guest
access solution.
A guest VLAN and service profile are created and bound to the Corporate SSID, and a guest
password is created. Guests can now visit Acme Works, log in using the guest password through a
web browser, and obtain access to the resources available on the guest VLAN.
As additional needs arise, the network administrator can easily add new VLANs and service
profiles, and change the available levels of service. New VLANs are created to segregate traffic for
the Manufacturing and Engineering departments, and new service profiles are created to
accommodate members of those departments. Special classes of service are assigned for
applications sensitive to interruption or bandwidth fluctuation, such as voice over IP, and low
priority, bandwidth-intensive applications such as FTP transfers.

Example 5: Large Campus with Branch Offices
This example shows how a company can incorporate centralized network management to control a
large campus with branch offices. The company has planned its network to include the NMS Pro
Network Management System. This solution will provide network administrators with extensive
control and oversight, centralized monitoring, and fault management.
The campus buildings and branch offices lend themselves to a hierarchical management structure in
which an NM Portal AP is configured on each building subnet. Each NM Portal AP handles policy
distribution and software upgrades at its location as directed by NMS Pro. The NM Portal AP also
serves as a backup security portal in the event that another RADIUS authentication server in its
authentication zone becomes unavailable.
The network configuration for this example is shown in Figure 13 and the feature decisions are
shown in Figure 14.
Figure 13: Example 5 Network
NOTE: AP configurations must be reset to factory defaults before they can be enrolled
by NMS Pro. For this reason, it is best to make the decision to use NMS during initial
network planning, before APs are installed in the network. For further information, see

Using Power Over Ethernet
Power-over-Ethernet (PoE), based on the 802.3af standard, can be used to supply power to the
Airgo AP. If both DC power and PoE are used at the same time, then failover takes place
automatically in the event that one of the power sources is lost. For failover, the following rules
apply:
•The AP uses the power source with the highest voltage.
•Unplugging either cable causes power to switch automatically to the other source, which may
cause the AP to reboot.

Method Description
Web browser
interface
Use the Configuration Management panel under System Configuration. See
“Reset Configuration” on page 249.
CLI Use the command sequence:
config
system >
reset-to-defaults factory-defaults
Reset and default
buttons on the AP
This is useful if the administrative password is lost; however, before
performing the reset, make sure to have the original factory-assigned AP
password available. Follow these steps:
1Make sure the AP is connected to power (power adaptor or Power-over-
Ethernet).
2On the side of the AP, hold down both the Reset and the Default buttons.
The button closest to the antenna is the Reset button. The button below it is
the Default button.
3Release only the Reset button and continue to hold down the Default
button. After 10 seconds, the Status LED blinks from red to green twice. If
the AP has a buzzer, a beep indicates that the restore operation has started.
4Now release the Default button. The AP continues to reboot. The Status
LED turns green when the reboot is successful and the AP is operational.
During this process, all passwords and configurations are reset to factory
defaults. If the AP was previously enrolled in a network, it must be re-
enrolled. The new administrator password is now the original AP unique
password that was set at the factory.
NOTE: The AP configuration may not revert back to factory defaults if the Reset
button is pressed immediately after issuing the reset-to-defaults factory-
defaults command from the CLI or applying the reset function from the AP web
interface (“Reset Configuration” on page 249). To ensure that the configuration reverts
back to factory defaults, allow the reset to defaults operation to reboot the AP
automatically.
Item Description
Password Each AP is shipped with a unique administration password provided in
the paperwork shipped with the AP.
Certificate Thumbprint Each AP internally contains a unique digital certificate and associated
thumbprint (key) included in the paperwork shipped with the AP.
IP Address When an AP boots for first time and is able to access a DHCP server, it
will obtain an IP address. If an AP fails to secure an IP address lease from
a DHCP server, it will default to the IP address of 192.168.1.254.
Each NM Portal AP should have a fixed IP address.
Using the Configuration Interfaces
Installation and User Guide: Airgo Access Point 33
Using the Configuration Interfaces
Four different secure interfaces are available for administering the Airgo Access Point:
•Web browser (https)
•Command line interface (SSH or console)
•SNMP (SNMPv3)
•Policy management (https, XML-based)
This section explains how to access each of these interfaces. The configuration procedures in this
guide are all presented using the web browser interface. For additional information on the CLI, see
the CLI Reference Manual.
Using the Web Browser Interface
The Airgo AP web browser interface is the easiest way to configure an AP or check the current
settings. It includes the QuickStart facility to get the AP running as quickly as possible with a full
set of AP features. NM Portal can also be launched from the web interface.
To connect to the AP using the web browser interface requires an IP connection to the AP network
and a computer with a browser capable of Secure Sockets Layer (SSL) connections. Follow these
steps:
1Launch the web browser.
aIf your network has a DHCP server, enter the DHCP-assigned address of the AP in the
address bar.
bIf your network does not use a DHCP server, assign the static address 192.168.1.1/24
to your computer, and then enter https://192.168.1.254 in the browser address bar.
2Depending on the browser security settings, a security alert may open with a prompt on
whether to accept the Airgo Networks security certificate. Click Yes to accept the certificate
and to open the login panel.
3In the login panel, enter or confirm the administrative username, enter the password, select a
language, and click OK to open the web interface. The factory default for administrator access
is username: admin. If the AP has not been initialized, the username field is grayed out. The
Security Mode The default security mode for the AP is WPA-PSK authentication with
AES encryption.
Radio Configuration The default global configuration for radio settings is “US, Indoor,” which
allows operation in all twelve IEEE 802.11a channels. “US, Any” permits
operation only in the middle and upper UNII bands (8 channels) for IEEE
802.11a (5GHz) operation.
Item (continued) Description
NOTE: In the web interface, a red asterisk (*) next to a field name indicates that the field is
required. Error messages are presented in text near the top of the panel below the

number of minutes.
•Assign Fixed Channel: Select a static channel.
NOTE: The fixed channel must be a valid channel number, and it must be
compatible with the AP hardware for the country in which the AP is installed. If
an invalid or incompatible channel is assigned, the bootstrapping process can
be completed successfully, but an error message appears to remind the user of
the channel incompatibility. If this occurs, change the channel assignment after
bootstrapping by following the instructions in “Global Configuration” on
page 61. This section includes a table of valid channel settings.
NOTE: The defaults for radio configuration have been selected for the best operational
radio behavior across a variety of environments. Modifying these parameters alters
radio behavior, which may have an impact on network performance or services. For
example, selecting an operating band of 5GHz (802.11a) may prevent legacy client
adapters from associating to the AP.
NOTE: If DHCP is used to assign an IP address to the AP, the lowest MAC address
should be pinned to the fixed IP address.

4Configuring Radio Settings
This chapter describes the configuration settings for the Airgo Access Point radios and explains
how to set the configuration using the Airgo AP web interface. It covers all the features accessible
from the Wireless Services menu except backhaul configuration, which is discussed in Chapter 6.
The chapter includes the following topics:
•Introduction
•Configuring Radio Parameters
•Setting the Advanced Radio Configuration
•Viewing Radio Statistics
•Viewing Radio Neighbor Details
•Configuring SSID Parameters
•Multiple SSIDs
•Configuring Inter Access Point Protocol (IAPP)
•Performing Radio Diagnostics
Introduction
The Airgo Access Point can be configured with one or two radios, each of which forms a distinct
wireless cell or basic service set (BSS), as shown in Figure 41. Each radio can operate in either of
the following modes:
•In normal mode, the AP is connected to the wired network and the radio directly services
downstream client stations or access points, or both. (AP mode).
•In wireless backhaul mode, the radio establishes a wireless link to a radio in AP mode on
another Airgo AP in order to relay data through the wireless medium. The AP is not attached to
a wired connection; instead it is connected through the wireless medium to another AP.1 In this
mode, the radio is called a Backhaul Point (BP mode). Wireless backhaul is also known as a
wireless distribution system (WDS).

•Channel Configuration — Configure channel usage for each radio.
•Performance and QoS — Configure enhanced data rates, performance attributes, and Wi-Fi
Multimedia (WMM) quality of service support.
•Admission — Specify categories of client stations permitted to associate to the selected radio.
To configure settings on these tabs, select each in sequence, or step through using the Go links at
the bottom of the panel (shown in Figure 42).
Many of the radio parameters are interdependent, and the Airgo AP performs consistency checks
during configuration to prevent user actions from adversely affecting radio performance. This is
especially true of dual radio APs, due to the proximity of the two radios. If you attempt to make
configuration changes that are not accepted by the AP, an error message may or may not appear.
Consult the appropriate section in this chapter to determine which parameters are in conflict.
Global Configuration
Use the Global Configuration tab (Figure 42) to define settings that apply to all configured Airgo
AP radios.
Figure 42: Radio Configuration - Global Config
NOTE: All the settings on this tab are optional. If the AP radio is enabled when the
global configuration is changed, then it is necessary to reset the AP for the changes to
take effect. If the radio is disabled, the changes take effect once the radio is enabled.
4 Configuring Radio Settings
62 Installation and User Guide: Airgo Access Point
Set the following global parameters on this tab:
Field Description
Network Connectivity Specify the mode of connectivity to the wired network.
•The default value of Any means that the AP auto-determines whether to
initiate a backhaul based on the presence or absence of an active Ethernet
link. The Any setting is influenced by the number of radios in the Airgo
AP and whether the AP has active Ethernet connectivity. If Any is
selected, the Airgo AP is allowed to change between wireless and wired
mode based on a change in Ethernet status.
•The Wired-Only setting means that the Airgo AP operates only as a wired
node. The node is disabled if the Ethernet link is not active. All radios take
on the AP persona unless explicitly configured as a BP radio.
•The Wireless value means that the AP operates only as a wireless backhaul
node with wireless backhaul connectivity to the wired network. One radio
is automatically assigned the BP persona and one the AP persona. Applies
to dual radio APs only.
The default setting of Any is recommended.
Network Density Set the wireless network density (low, medium, or high). Moving APs closer
to each other increases wireless capacity by providing higher data rates to
clients. To support this configuration, select the high density option. For
maximum coverage at lower data rates, use the low density setting. Each
setting determines the defer threshold parameters for the Airgo AP. The
default is low; the default setting of “low” is appropriate for maximum
coverage.
World Mode - Multi-
Domain Support
Enables or disables 802.11d operation. If Enable is selected, the radio
advertises country, channel, and associated maximum transmit power
information in beacons and probe responses to stations or clients in the BSS.
The default setting is enabled.
NOTE: The World Mode Country Code may be statically assigned to a
particular country due to restrictions prohibiting end-user selection of
frequency and transmit power by some Regulatory Agencies. Refer to the
system specifications for the AP being configured to determine the country in
which this AP is licensed to operate. Currently, the MIC in Japan and the FCC
in the United States require products producing radio waves in the 2.4 and
5GHz bands to adhere to frequency (channel) and transmit power
requirements and prohibit end-user selection of alternative frequencies
(channels) and transmit power.
World Mode - Country
Code
Specify the country of operation of the AP. Select Default to set the channel
and power for the radio to the factory default country setting (U.S.).
Alternatively, enter a country code from the pull-down menu.

Click Apply to save changes or Reset to return to previously saved values.
World Mode -
Deployment
Environment
Specify the type of environment in which the AP is installed (indoor, outdoor,
or both). Choosing the environment and country influences the channels of
operation that the AP or BP operate in or use for scanning and the maximum
radio transmit power. If the country or environment is changed, the following
occur:
•The channel selection setting is reset to auto-select channel at startup. To
configure a radio on a specific channel, apply the country configuration
and then specify the channel using the Channel Configuration tab (see
“Channel Configuration” on page 68).
•The channel set configuration is set to system-determined band
configuration.
•All radios in the AP are reset.
For reference, Table 9 provides a list of world modes, including countries,
environments, bands, and valid channels.
AP Name in Beacon Confirm the AP node name advertised in beacons and probe responses. This is
the AP name that clients see when they scan for access points. The default is
the unique ID derived from the Ethernet MAC address of the AP. It is
recommended that you accept the default setting. (required, AP radio only)
Background Scanning Enable or disable background scanning. Background scanning is performed to
collect radio interference and radio neighbor information from the
surrounding RF environment. If auto-select-channel is enabled with the
Periodic option, background scanning should also be enabled. See “Channel
Configuration” on page 68.

Click Apply to save changes or Reset to return to previously saved values. Click Reselect Channel
to force the channel selection algorithm for the AP radio to trigger, including a switch-over to a
better channel, if available. The Reselect Channel button applies only to the selected AP radio
interface.
Automatic channel
selection
Specify whether the channel is chosen when the AP is started, or whether it is
selected periodically. The time range for periodic channel selection is 30
minutes to 24 hours (1440 minutes). It is recommended that you accept the
default setting of automatic channel selection of periodic at 30 minutes.
Channel Set Determine which channels the AP scans in order to determine the best channel
for operation. If Auto-Selection is enabled, this determines the channel set for
auto-selection. The following choices are available for channel set:
Band — Select a specific band, or the system-determined band option
(recommended).
•The System determined band setting means that the system chooses the
channel list or band for each radio based on the number of AP radios, the
persona of the radio, and the channel set of any second radio in the AP. If
the radio is in AP mode, the node selects the best channel across both
bands. If the radio is in BP mode, the BP radio scans on both bands.
•If the Airgo AP is configured with two AP radios and Auto-Selection is
chosen for both, the preferred band configuration for both radios is System
determined. If both radios are in AP mode, one operates in the 2.4GHz
band and the other in the 5GHz band.
•If the band is 2.4 or 5GHz, the AP radio operates only in the specified
band. If it is set to 2.4GHz, the AP chooses only non-overlapping channels
for operation (for example 1, 6, and 11). It is not possible to set both radios
to operate in the 2.4GHz or 5GHz band.
•If both bands are selected, the AP radio chooses the best channel based on
the mode and band of the other radio on the AP (if installed).
•If a BP radio establishes a backhaul in the same band as the other AP radio,
this triggers the AP radio to change bands, provided that the AP radio is
configured for auto-selection and the system determined band.
Channel List — Enter a specific list of channels to be scanned, separated by a
single space (e.g.,1 2 6 11 13...). Overlapping channels can be specified in the
2.4GHz band.
