That's a sage top. Stop transcribing data when it's clearly available in text. So many errors come up due to this. Also, don't send screenshot of text, send text!
A better product would be HALOW 802.11AH combined with 802.11s Basically long range WIFI in the ranges of 1.5km up to 3km achieved thru 700, 800, or 900mhz frequencies and narrow bands from 1 to 8mhz. And combine that with mesh networking of 802.11s similar with the Alfa Halow-U. Then it becomes a great product. Some suggestions might be; - make Halow MIMO device for increased bandwidth up to 32mbps maybe. - lower frequency to 200, 300, and 500mhz and possibly increase the power output to somewhere in the 5, 10, 20 watts for increased range maybe 5 to 6 miles. - add removable battery for portability like a ham radio. - put it in a ruggedized case similar to an MPU5 for tactical usage with two removable MIMO antennas above. And a gx16 8pin port for ethernet connectivity. Also 2.4ghz wifi hotspot. Since it would offer similar functionality of long distance IP mesh networking to EUD or smartphones offering data, video, voice comms. - AES256 encryption maybe. - add a built-in hardware for voice comms like zello. Finished product would be a civillian MPU5 clone that would be low cost but definitely functional, robust, and cheaper. Market would be Military Enthusiasts, EMCOM, NGO's, Ham radio hobbyists, Airsoft and MILSIMs, and many others.
if i have intrinsically safe wireless transmitter did i need Zener or Galvanic barriers in control room to limit the voltage and the current , please answer my question . thanks
WirelessHART transmitters are wireless, and do not have wired connections to the control room, so barriers are not required. Class 1, Div 1/ Zone 0 devices are available for installation in Hazardous Areas, and there are hundreds of thousands installed in refineries and in upstream hazardous environments today
in my head, drawing upon a distant mechanical background, it looks like sending nuts down a bolt, each nut has a '12 o'clock marker' and it depends upon where you put that marker, in phase, out of phase, quarter phase, eighth, then when it comes to amplitude, its like sending a bigger or smaller not on that same bolt.
Thanks for this video! Pretty systematic way of doing this mentally. We can also modify this to the voltage log/dB expression of YdB = 20log(x) by changing the values in the dB column to 2x ie, 20 dB => 10 and 6dB => 2. So for example: 60dB would become: 20+20+20 = 10^3 = 1000 times And 26dB would be: 20+6 = 10*2 = 20 times Appreciate your effort to simplify this!
Small waves make big ripples. I totally appreciate all you have done for the WiFi community. I'm glad I pulled money out of my own pocket to come see you present at Sydney Opera House at Ekahau WiFiDesignDay after missing my flight from Brisbane. When are you comming back to Australia? Gold Coast is very nice!
Hugs Mr Parsons. I have never seen you that emotionally. But thanks for sharing your inner self. I can only recommend the readers of this thread to dig into Keith. He is doing and have done a lot for the wi-fi community. I even had the honour to be taught by him in a course. Great great guy
Time has changed and we see a new wifi standard every two years. The clients cant keep up with this. No matter all the goodness of WiFi 7 it is not a goto solution in enterprice networks. Just implementing 6E is a bitch. But I believe this will be a banger in private networks. For big business I guess we will wait for WiFi 8
Everything I know about troubleshooting WLANs, I learned from you, Karl, everything! You're one of the best in the industry, fantastic, informative presentation. BTW, who forced you to put on a coat? Never do that ever again ;-)
