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.
