With Extreme Power comes Extreme Responsibility

With Extreme Power comes Extreme Responsibility Have you ever wondered why RSSI values from validation surveys don’t match your predictive design?  Have you wondered why changing the AP transmit power doesn’t always correspond with RSSI values for the client? There are some subtle nuances to be aware of when setting the transmit power on Extreme…

WirelessHART Overview

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…

Extreme Packet Capture

With some of the new features coming down the pipe with WiFi6, affectionately known as “11ax”, it may prove a little more challenging to capture all the frames.  This blog describes the process to capture WiFi6 traffic using WiFi6 radio interface(s) of an Extreme (formerly Aerohive) access point.

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 diagnostic information. …
