Boy, not any more - I went through an entire MIT then Stanford Electrical 
Engineering education without anybody telling me what a dBm was. I had to 
take a class in the music department (!) to learn that (!!!). I guess 
building computers and making integrated circuits doesn't need dBm any more 
. . .

The funny thing is that Stanford was the home of Prof. Terman, and the EE 
building is called the "Terman Engineering Center". Terman was the author of 
a dozen or so classic EE texts that mostly dealt with building radios. I 
don't think Stanford has a course in RF engineering any more. I guess with 
cell phones, wireless internet and RFID the whole subject is starting to 
come back now.
