RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Noise <-100 dBm??? - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam. Note: The RF Cafe Forums were reconstituted in April 2021!

Below are the old forum threads, including 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:
