States that any radiator ( that which emits radio energy ), whether or not intentional, must be licensed unless it meets 47 CFR 15 or is otherwise exempted by the FCC.

One thing that might give a lift to infrared would be research demonstrating that the radio energy used in mobile phones and other devices is actually hazardous to human health, Kahn said.
33.
From the earliest wireless telegraphy days of radio, well into the age of commercial AM broadcasting, unamplified radio receivers were powered only by the radio energy they picked up through their antennas.
34.
Using a shorter duty cycle allows for better minimum range, but also means that less radio energy is being sent into space over a given time, reducing the strength of the return signal.
35.
On a very large scale, that could be 98 % efficient-but we don't know how much of the radio energy goes into splitting up the water and how much is wasted in other ways.
36.
The radio needs'AGC'( Automatic Gain Control ) because the amount of radio energy received by the radio depends dramatically on how far you are from the transmitter ( amongst a bunch of other factors ).
37.
The NSS transmitter fed one million watts of radio energy to its antenna, and during idle times, transmitted the string " W W W VVV VVV VVV DE NSS NSS NSS " in Morse code.
38.
Because the troposphere is turbulent and has a high proportion of moisture the tropospheric scatter radio signals are refracted and consequently only a tiny proportion of the radio energy is collected by the receiving antennas.
39.
Wi-Fi cards, wireless modems, hand-helds with wireless e-mail service and even cell phones with games are all what the FAA calls " intentional emitters, " devices that put out radio energy at a variety of frequencies.
40.
:Also, the part 15 device may transmit a small amount of radio energy, but part 15 gives these transmitters the least privileges of any transmitter; essentially, if the device bothers anyone, the operator must turn it off.
