Noise <-100 dBm??? - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

I'm using my pc to take signal readings of my wireless network. I'm using an orinoco gold card classic (with hermes chipset) and netstumbler as my utility. I am consistently getting noise readings <-100. Can anyone tell me how this is possible???

thanks
kevin

Here at PWB America, Inc. , we are excited about our new service we offer to our clients to eliminate Electromagnetic Interference (EMI) "Noise" at the PCB layout design level.

We will run your PCB layout on EMI Stream which will help our PCB Design Engineers to eliminate the causes of unnecessary electromagnetic radiation from the initial & final design stage, EMIStream substantially reduces the time and costs needed for revision after the prototype is developed which enables quick time-to-market turn around.

For more information regarding EMI Check and Resonance Analysis serivce, please contac us:
