Wireless CleanAir Deployment Guide
Smart Business Architecture
Business Overview
The challenges of running a wired data network are beyond the expectations
of most other jobs. The challenges go beyond simply adding a machine and
handing it over to the desktop IT department or to the end user to leverage as
they desire. With the numerous challenges that arise with any application, the
network is always the easiest entity to blame for failure. Now add a wireless
data network to the picture and the challenges and skill set required to maintain
and troubleshoot the network triple. Wireless networking brings a new set of
unknowns that a wired network never had to address.
The Cisco Wireless Control System (WCS) with CleanAir Technology allow the
The Cisco Wireless Control System (WCS) with CleanAir Technology allow the
Network Administration IT staff to visually see how well their network is per-
forming, troubleshoot client connectivity remotely, manage wireless network
resources, and analyze interference devices from anywhere in the world and
more. The real power of Cisco WCS with ClearnAir combined with CleanAir
access points is the ability to visually represent the radio environment to the
network administrator to better manage and troubleshoot issues before they
become issues.

Radio is the manipulation of the magnetic field that is invisible to the naked eye.
Without running expensive site surveys with a spectrum expert every hour and
minute of every day, the network administrator cannot tell what is happening
in the user space. The Wireless Control system collects the data from all the
Wireless LAN Controllers (WLC) in the network, while each CleanAir access
point does a spectrum sweep of the environment and alerts the administrator of
any potentially negative issue before a user creates a call ticket in the network
call center.

Unlicensed bands need to be proactively managed. Wi-Fi is no longer a con-
venience technology used for casual web surfing or simple connectivity from
conference rooms. With 802.11n, wireless performance is now on par with wired
networks where businesses as well as hospitals rely on the wireless network
for mission-critical and patient-critical applications. With limited IT resources,
lack of tools, and lack of RF expertise, the CleanAir access point with Integrated
Spectrum hardware can fill the RF expertise gap and limit or eliminate network
downtime.
With Event Driven Radio Resource Management, an issue within the wireless
With Event Driven Radio Resource Management, an issue within the wireless
radio network can be identified and mitigated without any user interaction.
Alerts can be sent out via email as well as through syslog to make the network
IT staff aware of the mitigated issue and alert them to watch for other issues,
enforce the company radio policy, or do both.
