Nothing much of interest. It's about as interesting as getting a sports car up to about 75 mph and pulling back on the wheel. Not much happens. Now, do that in a small airplane and pull back on the wheel. Yippee! From: emc-p...@ieee.org [mailto:emc-p...@ieee.org] On Behalf Of Conway, Patr

Recently we added two new food blasters to the lunch room and noted that some office areas no longer had reliable network connect. Installed some isolation transformers between building mains and the food blasters - no more complaints from the sales/accounting dweebs, or whatever they do. Also not

Brian, Can you change the WLAN to operate in 802.11a mode which uses the 5GHz band? 11b/g is in the 2.4GHz band. The Access Points will most likely be able to support 11a but older clients may not. BTW - I've worked in the WLAN space for a couple of years and never heard of such a large issue wi

Brian I have experienced two microwave production systems. Shielding helped a little, however, because product had to pass through it was not possible to completely mitigate the EMI and the situation was very difficult. In your case it is from commercial microwave ovens. The biggest source of em

Except for rebuilding the break rooms with foil-lined dry wall, metal flooring, screened windows, filtered power, waveguide-beyond-cutoff ventilation grills, and RF tight doors, I don't know there is much for a solution. I was told that in one major Boeing plant, communications as 2.4 GHz is all b

Brian As you know, the operation frequency of Microwave-oven uses same ISM band including 2.45GHz by which "Magnetron", main component of microwave oven is oscillated. It means, even though you use another new one, a little EMI will happen between Microwave oven and Wireless LAN. Best way is to re
