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 –…
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 IoT solutions to…
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 service) and TDWR (Terminal Doppler Weather Radar). …
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…
Understanding LoRaWAN Frequencies The LoRaWAN Regional Parameters RP2-1.0.3 (released May 2021) describes regional parameters for different regulatory regions worldwide as related to LoRaWAN. Separating this document from the LoRaWAN protocol specification allows the addition of new regions within the parameters document while not impacting the protocol specification. Globally, LoRaWAN is broken down into channel widths…
To ‘E’ or not to ‘E’…. That’s what I do: I drink and I know things. – Tyrion Lannister Often times, passionate people find excuses to quarrel about what really can be reduced to trivial and time-wasting debates. Two specific examples of this come from two of my favourite fields –Whisky and Wi-Fi. While…
Want some 6 GHz with your Poutine? In days of past, Canada demonstrated leadership to the world in the culinary arts when it was first to combine French fries, gravy, and cheese curds – making the classic dish, “Poutine”! Once again, Canada has flexed its leadership muscles to approve license-exempt use of the 6 GHz…
