Re: [802SEC] Overview of proposed FCC rules changes and potential to impact 802.11, 802.15 and 802.16
Paul,
Funny how it is that after hitting the send button you realize that something was left out.
The spectrum etiquette is plain and simple a co-existence mechanism developed for the UPCS band. The Commission is asking if a similar method should be applied to other frequency bands.
Regards,
Mike

> The origin of the term "spectrum etiquette" is from the rules that the FCC developed for the unlicensed PCS (UPCS) band. Originally that was 1910 - 1930 MHz. Since that time the 1910 - 1920 MHz segment has been designated for licensed use, leaving only the 1920 - 1930 MHz segment. What could be imposed as a result of this proposal may not be identical to what is used for the UPCS band, but this is the example that the Commission is referencing.
