We often hear that WiFi network performance degrades due to radio interference. We also hear that interference is a complex beast which cannot be easily tamed. There are two types of interference sources which affect WiFi network performance – non-WiFi sources and WiFi sources. This post provides a guide to some practical steps to combat often cited non-WiFi interference sources such as microwave oven, Bluetooth, baby monitors, cordless phones, wireless cameras and jammers. The WiFi interference sources will be discussed in later post.
Overall, some awareness of environment around WiFi network coupled with some simple network planning steps can help win over non-WiFi interference to great extent. Additionally, ability to detect high interference levels on WiFi channels helps detect “unmanaged” sources of interference such as jammer or any unknown source. Many WLAN and wireless security systems today have ability to monitor interference levels on channels on 24×7 basis to facilitate such detection.

This informative Webinar offers a practical guide for selecting a WLAN security solution.
Dr. Hemant Chaskar, Director of Technology at AirTight Networks explains the prevalent methods for wireless access point detection and classification.
Attendees will learn:
- The difference between active and passive approaches to wireless intrusion prevention
- The core capabilities of different approaches to wireless intrusion prevention
- What to look for when testing systems to assure that there are no gaps in WLAN security
- How to judge when you need more capabilities than you currently have
After the event, attendees will receive a sample test plan to help plan their own comparative testing among vendors.

AirTight’s director of technology joins HP ProCurve executives for two informative sessions at the HP Technology Forum in Las Vegas
June 15-18, 2009, Mandalay Bay, Las Vegas, Nevada, USA
Session: Wired/Wireless Management
Speakers: Dr. Hemant Chaskar, Director of Technology, AirTight Networks, Carl Blume, HP
This session offers timely advice for managing wireless and integrated wired/wireless networks from the perspectives of security, policy enforcement, performance optimization, and scalability.
Session: Wired and wireless Security
Speakers: Dr. Hemant Chaskar, Director of Technology, AirTight Networks, Mauricio Sanchez, HP
This session will present some differences and commonalities between protecting your network in a wireless versus a wired environment. It will outline the fundamentals of a comprehensive, multi-layered network security strategy and will drill down into some specific IDS/IPS (intruder detection system/intruder protection system) solutions that are particularly useful for combating wireless threats.

“There are several ways to scan your 802.11n air environment for nasty goings-on. At a glance, the options seem pretty straightforward. However, you need to look carefully under the hood to draw a true apples-to-apples comparison of the accuracy and cost of the various offerings.”
