#185583 - Don't need kW to jam civilan "toy" equipment
Responding to: Jecksons Ben's previous message
You don't need to look at huge transmitters. I gave them as an example where a very strong jumping transmitter requires a jamming transmitter with huge power output.

But our commercial transmitters have miniscule power output so you do not need a private nuclear reactor just to power the jamming transmitters.

It's enough to look at the behaviour of WLAN, Bluetooth etc - the bandwidth are very much affected by the number of other weak transmitters operating in the same frequency bands.

And a person who explicitly wants to jam a transmitter is hardly likely to look at the regulations. If a legal transmitter has 10 mW, then 500 mW will represent a quite strong jamming signal.
