Overview

Cisco ® announces the availability of Cisco Unified Wireless Network Software Release 4.1.190.5. This release is the first in a series of software releases separate from the main release sequence or "train" for the Cisco Unified Wireless Network. Extended wireless mesh functionality is delivered in this series, and will only be available in this release series until the features are merged back into the main train at a future date. Although customers operating both a wireless mesh network and a network of standard access points will need at least one wireless LAN controller for each release, they will continue to enjoy the benefits of the Cisco Unified Wireless Network. A single network design and policy set can be deployed across the network access points, while clients continue to roam seamlessly between access points based on 4.1.x.x, regardless of whether the access point is a standard access point or a mesh access point. Moreover, customers can manage all of their access points with a single instance of Cisco Wireless Control System, regardless of which controller the access point is connected to.

Access Points

Cisco Unified Wireless Network Software Release 4.1.190.5 supports the following mesh access points:

• Cisco Aironet® 1505 Lightweight Outdoor Mesh Access Point

• Cisco Aironet 1510 Lightweight Outdoor Mesh Access Point

• Cisco Aironet 1522 Lightweight Outdoor Mesh Access Point

It does not support other Cisco lightweight access points, such as:

• Cisco Aironet 1000 Series

• Cisco Aironet 1100 Series

• Cisco Aironet 1130 Series

• Cisco Aironet 1200 Series

• Cisco Aironet 1230 Series

• Cisco Aironet 1240 Series

• Cisco Aironet 1300 Series

For lightweight access points not supported with this release, please use a separate wireless LAN controller with Release 4.1.185.0 or another release that supports your access points.

Wireless LAN Controllers

Cisco Unified Wireless Network Software Release 4.1.190.5 is supported on the following controllers:

• Cisco 2100 Series Wireless LAN Controller

• Cisco 4400 Series Wireless LAN Controller

• Cisco Catalyst 6500 Series Wireless Service Module

The Cisco Unified Wireless Network Software Release 4.1.190.5 supports wireless mesh functionality for Cisco IOS ® Software-based platforms in addition to platforms based on VxWorks. For VxWorks-based platforms, Release 4.1.190.5 builds upon the features available to mesh access points in Release 4.1.185.0. For Cisco IOS Software-based platforms, Release 4.1.190.5 provides many of the features available to VxWorks-based platforms in Release 4.1.185.0, although some features will not be delivered until a later release.
Please refer to documentation for Release 4.1.185.0 for information about features supported by the Cisco Unified Wireless Network.
Note that Cisco Wireless Control System Release 4.1.91 manages controllers using version 4.1.185.0 and 4.1.190.5. You do not need a separate instance of WCS to manage each controller.

Mesh Software Image Selection Guideline

Refer to these guidelines to determine which release is best for you.

Indoor, non-mesh APs only

Follow the Controller Main Line Release Train (e.g. 4.1.185.0, 4.2). See Mesh Software Image Roadmap Diagram below.
Do NOT upgrade your APs to release 4.2 if you intend to use your indoor APs in mesh mode as Enterprise Wireless Mesh APs when this feature is available in the Fall 2007 mesh release (this is referred to as Mesh Release 2, and follows on to Mesh Release 1-4.1.190.5). Instead, use release 4.1.185.0, and migrate to this follow on release.

Outdoor and indoor APs

• Europe, Singapore, and other countries needing DFS functionality

Use release 4.0.217.203. Migrate to Mesh Release 2 when available in Fall 2007 (Mesh Release 2 is on the Mesh Train and follows Mesh Release 1-4.1.190.5).

Do NOT use any release from 4.0.219.0 through 4.1.190.5, or 4.2. If you require functionality provided in one of these releases for your indoor APs, you will need to use a separate Controller; but note that your clients will not be able to seamlessly roam between indoor and outdoor APs. You can merge back into a single Controller with Mesh Release 2, or you can continue on the Controller Main Line Release Train for indoor-non-mesh APs with a separate Controller. (Again, your clients will not be able to roam seamlessly between indoor and outdoor APs if they are on release derived from different major releases [i.e. 4.1 vs. 4.2].)

• US and other countries not needing DFS functionality1

Use release 4.1.190.5 for your outdoor-mesh APs, and use a separate Controller for your indoor-non-mesh APs. Migrate to Mesh Release 2 available in Fall 2007. Mesh Release 2 will support all unified APs-outdoor-mesh APs, indoor Enterprise Wireless Mesh APs, and indoor-non-mesh APs.

If you require functionality for your indoor APs provided in the Controller Main Line Release Train (such as in release 4.2), you will need to use a separate Controller; but note that your clients will not be able to roam seamlessly between indoor and outdoor APs.

The Features Supported by Different Cisco Aironet Access Points

The features available to you in Cisco Unified Wireless Network Software Release 4.1.190.5 will depend on which access point you are using. Table 2 provides a summary.
The Cisco Aironet 1505 access point uses the VxWorks operating system. It is a single band access point, which uses its 802.11b/g radio to provide access to clients as well as backhaul traffic between mesh nodes.
The Cisco Aironet 1510 access point uses the VxWorks operating system. It is a dual- band access point, using the 802.11b/g radio to provide access to clients, and the 802.11a radio to backhaul traffic between mesh nodes.
The Cisco Aironet 1522 access point uses Cisco IOS operating system. It is a dual-band access point, using the 802.11b/g radio to provide access to clients, and using the 802.11a radio to backhaul traffic between mesh nodes. The Cisco Aironet 1522 access point optionally supports a DOCSIS 2.0 cable modem or fiber module to connect to the wired network.

Mesh Access Point Interoperability

With software Release 4.1.190.5, the Cisco Aironet 1522 access point can be a rooftop access point (RAP) to a Cisco Aironet 1522 or 1510 mesh access point (MAP). The Cisco Aironet 1510, however, can only be a RAP to a Cisco Aironet 1510 MAP. Table 3 shows access point interoperability.
