Cisco CleanAir is the solution of spectrum intelligence that Cisco has designed for managing the challenges that many shared wireless spectrum cause. Cisco proactively creates this system to enable everyone in the working environment to see all the shared spectrum users, whether they are the original devices or the outside interferers. Users can also act to make changes on the network.

How Cisco CleanAir Delivers Its Utmost Solution to All Enterprises

How to Deal With Cisco CleanAir

Some companies might be still wondering how they can deal with this system. Some shared networking doesn’t allow certain users to make changes. But, this system is more than just extraordinary.

Users can remove any interfering, unnecessary device in a manual way. Or, users can operate the system to change any channel automatically if it makes any unnecessary interference. The basic aim of the CleanAir system is the ability to provide spectrum management with Radio Frequency (RF) visibility.

Its operations theory is actually components system software and hardware for providing the ability for measuring the quality of WiFi channel. The system can also identify non-sources of Wi-Fi and other kinds of channel interference.  What makes this program special is such measurement can’t be done by common Wi-Fi chipsets.

Users should learn about how CleanAir operates perfectly at its best level. This is to ensure that they comprehend the basic requirements and goals design to implement them successfully. For any company which is already well-known with the technology of Spectrum Expert by Cisco, then they know that CleanAir is an evolutionary technology. Yet, it is a totally novice kind of technology that is almost the same to Spectrum Expert, though there are some differences.

Several Kinds of CleanAir System

Here is how it works. This system includes the CleanAir-enabled access points that gather information regarding all operating devices in any industrial or company bands to the Wireless LAN Controllers. Yet, the access points already recognize and estimate the information as the source of potential interference.

Then, the Wireless LAN Controllers will control the access points before collecting spectrum data. Afterward, the controllers will forward the information to either Cisco Prime Infrastructure or the Cisco MSE (mobility services engine), based on operators’ requests.

The CleanAir system will inform users about each device that operates in the unlicensed band, and inform the location and its overall impact on the wireless network. What’s more, the system will inform the most applicable actions that users and their network do. The system makes RF getting simpler, even if users don’t really master RF.

This system is very important because the Wi-Fi system can influence some electronic devices. Some people might not aware of this influence on their home appliances like microwaves, Bluetooth devices, and so forth.

The CleanAir System's main components are the Wireless Control System and Mobility Services Engine. Both of them should work together to increase the better CleanAir effectiveness, so users can obtain the maximum value from the CleanAir system supplies information. The system can provide user interfaces for the more sophisticated spectrum capabilities, including historic charts, tracking interference devices as well as location services along with the impact analysis.

Any company that uses an AP can make the most of the CleanAir technology for gathering information that relates to the sources of non-Wi-Fi interference. Afterward, the AP will process it before forwarding it to the WLC that becomes the main integral part of the system. The WLC has the main ability to control and configure the AP that has CleanAir capability before it is collecting and processing spectrum data. Then it will provide the data to the WCS or the MSE.

Here, the WLC offers GUI and CLI as the local user interfaces for configuring the basic features and services of CleanAir and put on view the available information of the spectrum. Then the WCS offers CleanAir’s advanced user interfaces which comprise several things. They include the feature enabling and configuration, the merged display information, and the previous record or Air Quality and engines.

Why CleanAir System of Cisco Is Worth Choosing

CleanAir system of Cisco integrates well with the function of Cisco Unified Wireless Network, in which it can manage the interference problem that relates to RF. It is very common to find some phenomenon about the sophisticated WLAN services that don’t work properly, due to the ISB bands' legal usage interference.

This is why the CleanAir system is also applicable for users who want to solve the radios with backhaul problems while providing details of report interference with the air quality. Configuring the CleanAir system can be done, whether it is on a controller or an access point.  The manuals are available on the official website of Cisco.

How CleanAir System Detects Interferers from the Access Point

When users have enabled the CleanAir System, the access point can detect some devices that interfere. The system can also make some detections from several merged sensors of the same device for creating clusters. Then, every cluster will get a different ID. Then, some of those devices preserve power by making limitations of the transmit time. The limitation takes place awaiting the required spectrum sensor result to stop the device detecting process temporarily.

During the detection process, there will be some devices that are marked as damaged or facing troubles. They will be removed from the database. But, what if all devices are detected as interference? Then, the system will maintain the cluster-ID several times, in order to avoid the chance of the bouncing of device detection.

Whenever the detection refers to similar devices, then they will be combined with the original cluster-ID. The system will preserve the device detection history. Let’s make a clear example of this. Let’s say that a Bluetooth keyboard relies on the power of a battery.  It employs some methods for reducing the consumption of electricity. It can turn off the transmitter if it is not required. It causes the device to appear in the oscillating system. 

Cisco CleanAir system usually manages this problem by keeping the cluster-ID for a longer time. Afterward, it will be combined into one record after it finishes detecting. Such process can simplify the records of user and represents the device history in an accurate way.
