Wireless LANs use the license-exempt radio bands shared by various consumer-grade transmitters. These devices can have a serious negative effect on the performance of your WLAN. In order to isolate these noise sources you need a mobile spectrum analyzer with fast response and an internal expert system that automatically identifies the type of transmitter causing the problem.

This time Rick will discuss the pros and cons of wireless perimeter defense mechanisms, looking specifically at the pros and cons of using double-duty and dedicated APs compared to purpose-built security sensors and the advantages of fully featured overlay WIPS systems compared to integrated security monitoring consoles.

1 hour webinar presented by Rick Murphy. With the proliferation of smartphones, tablets, and Windows 7 PCs, that allow the formation of personal WiFi Hotspots, WLAN rogue AP detection is becoming even more of a priority for WLAN administrators of networks of all sizes. In addition, increased emphasis by the FCC and most other national radio regulatory agencies on enforcement of RF jamming laws are making it crucial for WLAN engineers to positively identify unauthorized devices before performing containment activities ...

Once again Rick has pulled off another successful webinar, “Tired of Walking the Floor? Survey in Half the Time.” Industry best practices consider site surveys as a mandatory and vital part of the wireless LAN deployment process for achieving the desired security, performance and compliance for the WLAN.

In this second part of Rick Murphy’s popular 802.11n Essentials and Applications webinar, he will explain some of the new and often confusing High Throughput (HT) options, such as use of 20/40 MHz Channels, additional subcarriers and optional Short Guard Intervals (SGI), which can have a significant effect on the performance of your WLAN.
