Extreme Private-PSK (PPSK) This post provides an overview of the Private Pre-shared Key (PPSK) feature available in Extreme Networks’ access points connected to ExtremeIQ. Explanations below provide greater detail with additional context and options for advanced configuration; however, it takes less than 5 minutes to configure a PPSK enabled SSID with three unique PPSKs to…
WirelessHART: An Overview – Presentation at WTF20 A quick post to provide a link to the slides I presented during the Wireless Technology Forum (WTF) Conference in 2020. My topic was WirelessHART: An Overview, providing a 30 minute highlight of this industrial process control based IoT protocol. Below is a link to the video presentation…
WirelessHART Spectrum WirelessHART is based on the IEEE 802.15.4-2006 standard – meaning specific flavours of the standard have been adopted by WirelessHART. This blog with address the channel and modulation characteristics defined in the IEEE 802.15.4-2006 standard and which features and combinations were specifically adopted by WirelessHART. The 802.15.4 standard titled “Wireless Medium Access Control…
Zigbee/BLE packet capture with NXP KW41Z Quick blog to document the procedure I used to install the software required to packet capture Zigbee and BLE traffic using the NXP KW41Z. You can find hardware details about the NXP KW41Z on the NXP website. There are a few different hardware models, so be sure to purchase the KW41Z…
BLE Overview This is a quick overview covering the highlights of Bluetooth® Low Energy (BLE) referenced in one place. As with all first-time Bluetooth blogs, there is a mandatory requirement to describe the story of how Bluetooth earned its name. The name ‘Bluetooth’ is a head-nod to King Harold Blatand of Denmark. King Harold was…
WirelessHART Overview WirelessHART™ is a protocol developed to form self-optimizing, self-healing, time synchronized mesh networks. It easily extends wireless capabilities from HART® technology allowing compatibility with existing HART devices, commands, and tools. It’s based on the IEEE 802.15.4™ standard and operates in the 2.4 GHz ISM band allowing for near global operation. HART version 7, maintained by…
HART Overview This is the first of what is planned to be a many part series detailing the history, protocol and design best practices for WirelessHART™. Before diving into the details of WirelessHART, let’s unpack the HART® standard upon which WirelessHART was built. HART technology has opened up a wealth of digital process, maintenance, and…
