It is called a de-authentication attack.

But with a 2.4 Ghz you can cause problems. (videolinks, remote
controls/alarm systems on 2.4 Ghz) 

setting up you own 2.4 network (and play with ping -f) in the same band
may cause enough prolem without being illegal.

Find people and talking with them is generally the best solution.

Gathering information abount what is in the air can be done:
for wifi
 - kismet (or derived)
 - netstumble (windows only)
"raw"
 - wispi
 - airview

Spending some money on the airview (wispy got more expensive)
and is very educating (and entertaining) and worth spending some money
one.

2ct.
