Cisco CleanAir battles Wi-Fi smog

摘要

There's a long-standing need in wired networks to verify the quality of connectivity of wire, cable and fiber with appropriate test equipment. But with wireless networks, this requirement extends beyond initial site surveys and occasional troubleshooting.rnManagers of wireless networks have an ongoing need for spectral analysis, viewing not just protocol-based traffic but also energy in a given band. And this monitoring needs to be constant, because interference can appear at any time.rnAt Farpoint Group, we refer to the analysis of energy at the physical layer to improve performance as spectral assurance.
