DOGEcoin miner on Raspberry Pi I happen to have a handful of Raspberry Pi 4’s lying around and thought I would experiment with setting them up as DOGE coin miner. Appreciate that this is more of a proof-of-concept (PoC) exercise, the Pi is not going to fill your crypto wallet with DOGE coins. Instructions below will…
LoRaWAN: An Overview – Presentation at WLPC 2022 A quick post to provide a link to the slides and video for my presentation during the Wireless LAN Professionals Conference (#WLPC) in 2022. My topic was LoRaWAN: An Overview, providing a 30- minute overview of this long-range, low-power, IoT technology deployed in over 160 countries. Additionally,…
Many network professionals get excited about collecting packet captures to dive into the packets of truth to troubleshoot or better understand the nature of data flow across their networks. While capturing WLAN traffic is easier than it used to be, efficient packet analysis is still an art form. Let’s look at some advanced techniques to…
The ability to change the colour of AP icons was added in the release of Ekahau Pro version 10.3.1. This can be done by entering the AP edit menu and selecting the desired colour. APs can be modified one at a time or by bulk selection of APs. Bulk selection can easily be accomplished using the “Quick Select” feature to…
There are many complicated techniques that can be employed to measure the attenuation values of various building materials to use within a predictive RF design. As fun and exciting as they can be, this post will explain a process to measure wall attenuation using the latest release of the Ekahau Survey v2.0 app for iOS. This technique can be…
Have you ever been stumped trying to figure what wall attenuation value to simulate in your predictive RF designs? Have you wondered if reinforced concrete is “thicker” then a wall constructed with masonry bricks? The chart below summarizes relative attenuation values from common building materials as tested by NIST way back in 1997. Shockingly, concrete yields…
This list will summarize the 802.11 standards that have been rolled out over time. A quick bit of trivia: the number 802 comes from the first working group formed in the second (02) month (February) of 1980. The family of wireless specifications that we have affectionately come to know as “802.11” was first released in 1997 –…
CWISE: IoT Expert Certification from CWNP The global IoT and communications market is expected to reach USD21.3 billion by the year 2022, according to Gartner. Not surprisingly, a market expectation that large has captured the attention of IT professionals. Additionally, it has attracted those outside traditional IT roles who may be tasked with the design and deployment of…
DFS radar avoidance – maple syrup style This blog describes the details of DFS (Dynamic Frequency Selection) on a wireless access system (WAS) as regulated by the Innovation, Scientific, and Economic Development (ISED) branch of the Canadian government. Specifically, this will cover Wi-Fi operating on 5GHz using channels exhibiting co-channel operation with EESS (Earth exploration-satellite…
Atom is a powerful and customizable text editor, supported across the primary operating systems (MacOS/Windows/Linux). There are many text editors out there, but to keep things consistent for new Python developers, Atom was selected. It also doesn’t hurt that Atom is available at no cost. The entire Atom editor is free, open source, and available…
