Packet Capture with AP Radios – What’s Under the Hood?

packet capture

Wireless packet capture has always been important to Wi-Fi professionals and support engineers for resolving network problems. With the diversity of wireless clients that is already around and which is only expected to grow with the Internet of Things (IoT), packet capture capabilities will continue to be critical. Wireless packet capture can be facilitated in… Read More

Peek Inside 802.11ac Access Point Hardware Designs

802.11ac-design2.png

There is large and ever increasing assortment of enterprise access points offered by wireless vendors today.  APs have different number of radios, number of streams, 11n/11ac, POE compatibility, peripherals, price, etc. While this diversity is overwhelming, have you wondered what lies in the hardware guts of these APs? What are the hardware design concepts that… Read More

Corner Cases

Trade shows

Most Wi-Fi manufacturer’s marketing departments would have you believe that 99% of all deployments are what I’d call “corner cases.” I call B.S. (as usual). Here are the high-density/high-throughput (HDHT) corner cases that so many manufacturers would have you believe are so prevalent: Large K-12 and University libraries, cafeterias, lecture halls, and auditoriums Stadium or… Read More

Hunting down the cost factors in the cloud Wi-Fi management plane

Cost

Mature cloud Wi-Fi offerings have gone through few phases already. They started with bare-bones device configuration from the cloud console and over the years matured into meaty management plane for complete Wi-Fi access, security and complementary services in the cloud. Alongside these phases of evolution, optimizing the cost of operation of the cloud backend has always been important consideration. It is critical for cloud operators and… Read More

Controller, controller-less, cloud Wi-Fi: What does it mean to the end user?

Wi-Fi

Wi-Fi architectures today come in three main flavors: controllers, controller-less and cloud. While vendors spar over which is the right architecture for today’s and tomorrow’s Wi-Fi, customers are mostly interested in comparing them based on their derived value.

In this blog post, we examine the economics, manageability and ease of deployment of these 3 architecture flavors. On these fronts, I have often seen the following 8 points to be most relevant to customers while making architecture choice for their Wi-Fi project.   Read more

How “soft APs” can create “soft spots” in your network security

In several of my recent wireless scanning exercises, I have encountered soft APs much more often than before. In one case, it was an employee who returned from business trip who had used USB WiFi AP in hotel to share his Internet connection with fellow workers (well, they did not all want to pay $5… Read More

Ugly, Bad and Good of Wireless Rogue Access Point Detection

Classification

One critical requirement from wireless intrusion prevention system (WIPS) is that it should offer robust protection against rogue wireless access points. The protection should entail instant detection followed by automatic blocking (prevention). Rogue AP detection should be free from false alarms – both on positive and negative sides. Rogue AP means unauthorized AP wired to… Read More
