AWC-CB (AWC-Channel Blanket)

AWC-CB (AWC-Channel Blanket) is a single-channel architecture. This means that multiple wireless APs use the same channel and form a single large virtual AP to provide network access to clients. The main difference between single-channel and multi-channel architectures is the use of the Wi-Fi channels. Multi-channel uses all available channels which are carefully managed to avoid interference, whereas single-channel uses one wireless channel to create a single "blanket" of wireless coverage, thereby eliminating interference.

◼ Multi-channel Wireless Networks
In a conventional multi-channel wireless network, multiple wireless APs are configured to use different channels to cover a wider area than a single AP can cover.
With this configuration, there are complexities in channel planning, and problems such as packet loss, caused by inter-AP roaming, and slow traffic, caused by sticky clients. Sticky clients maintain their association with the AP that they are initially connected to, even once that AP is at a distance.


◼ Blanket Wireless Network
On the other hand, in a channel blanket (or blanket) wireless network, multiple wireless APs use the same channel and form a single large virtual AP to provide network access to clients. In this configuration, communications can be more stable, without roaming causing packet loss and sticky clients, because only a single channel is used. This also removes the need for complex channel planning.
However, because all clients send and receive traffic on the same channel, only a single AP can transmit at a given moment, therefore downlink throughput will decrease.
AWC-CB uses patented "Multi-Communication Technology" to let multiple clients on a blanket network send/receive data simultaneously using separate APs, as long as they do not interfere with each other.

The following table shows the differences between multi-channel and blanket wireless networks.
Table 1: Comparison between Multi-channel and Blanket Wireless Networks
  Multi-channel (Conventional) Blanket
Roaming POOR...
Depending on clients 		GOOD
Zero Time
Easy Deployment NOT GOOD...
Complex channel planning is required 		GOOD
Because of using a single channel,
channel planning is not required
Throughput OKAY
By limiting the number of clients per cell
high throughput can be achieved. 		POOR...
Because of using a single channel,
throughput decreases with more clients

◼ Hybrid Wireless System
With AWC-CB, it is possible to easily build a hybrid wireless network, which combines the strengths of both multi-channel and blanket networks. Multi-channel and blanket networks can be configured on a single AP, where the multi-channel networks are defined as ordinary VAPs in an AP Profile and the blanket networks are defined as VAPs in a CB Profile.
For example, by assigning static, high-throughput stations such as PCs to multi-channel VAPs and putting mobile, low-throughput devices in blanket VAPs, your network as a whole can be utilized and managed more efficiently.

Note
Because a channel blanket controls multiple APs as a single large virtual AP, individual APs in the channel blanket transmit beacon signals in turn. Some clients may appear to have unstable signal strength, due to receiving beacon signals from wireless APs other than the wireless AP that they are connected to. This does not cause any problems with network traffic quality.

Required Licenses

The following licenses are required to use AWC-CB functions with the AWC Plug-in:
For the Wireless Channel Blanket license, you might need more than one license, depending on how many APs you want to operate in AWC-CB (AWC-Channel Blanket) mode. A single Wireless Channel Blanket license lets you operate 10 APs in AWC-CB mode. Adding more licenses increases the number of APs which can operate in AWC-CB mode.
For example, the following licenses are needed when you run 40 APs in a multi-channel wireless network and 25 APs in a channel blanket network.
Table 2: An example of required licenses
  Multi-channel AWC-CB Total
Number of APs 40 25 65
Vista Manager EX License 1 1
Wireless LAN Controller License (10 APs) 4

Steps to Create a Hybrid Wireless System

To build a hybrid wireless system, follow the steps below.

◼ Build from scratch (with new wireless APs)
  1. Physically install the APs.
  2. Add the APs to the AWC Plug-in's management database.
    Add them on the AP Settings page.
  3. Place the APs on floor maps.
    Create floor maps and place APs on them on the Floor Map page.
    If you select APs from a list of APs in a management group at step 6, you do not need to create floor maps. However, it is recommended that you create floor maps if you have a lot of APs in a single management group.
  4. Next, create the AP profile.
    Create an AP Profile on the AP Profile page. Then configure general, system, wired network, wireless network and multi-channel VAPs.
  5. Create a CB Profile, which bundles together the common settings for a blanket network.
    Create a CB Profile on the CB Profile page. Then configure CB VAPs (VAPs for blanket networks) in addition to the profile name and management group.
  6. Create a channel blanket which you want to apply the CB Profile to.
    Create a channel blanket on the CB Profile page and select member APs.
    Member APs can be selected visually on floor maps, or can be selected on a list of APs in a management group.
    Refer to Create Channel Blanket for more details.
  7. Apply the AP Profile to the APs.
    The APs remain unmanaged until you apply an AP Profile to them.
    Once the AP Profile is applied to the APs on the AP Settings page, the APs' status changes to "Managed" and both multi-channel and blanket networks are made operational.

◼ Re-configure existing APs
  1. Create a CB Profile, which bundles together the common settings for a blanket network.
    Create a CB Profile on the CB Profile page. Then configure CB VAPs (VAPs for blanket networks) in addition to the profile name and management group.
  2. Create a channel blanket which you want to apply the CB Profile to.
    Create a channel blanket on the CB Profile page and select member APs.
    Member APs can be selected visually on floor maps, or can be selected on a list of APs in a management group.
    Refer to Create Channel Blanket for more details.
  3. Apply changes to the APs.
    Once the CB Profile is applied to the APs on the CB Profile page, the blanket network becomes operational in addition to the existing multi-channel networks.
    Refer to Apply CB Profile for more details.
