1 dBW = -30 dBm? I don't think so. -30 dBm is actually -60 dBW. I think what you meant was that 1 Watt = 30 dBm. Also I think S = E^2/377

That's correct, thanks!

Dr.EMC your workis great and you explain things very well and make it easy for a laman like me to follow , i have a question because i live in an apt building ive noticed when i go to play any online game on my pc i notice this sluggishness that makes the game feel unresponsive to the touch(not smooth and fast)but sometimes late at night i notice my games will suddenly feel very responsive and the immersive feel is ther, ive been struggling with this for a while now and i have a higher end pc some are saying some sort of emi or rf lag if maybe you could shed some light on this or possibly help solve the issue it would be immensly apreciated. I just dont know if it could be interference coming from the dsl internet line in the building or..?

Hey, thanks! Afraid that's just how internet works - slow during the day, fast at night. Fibre optic is probably the best option in the market right now. en.wikipedia.org/wiki/Internet_bottleneck
