[ietf78-tech] # AP's for plenary?

[joel jaeggli]

The plenary rooms do tend to run somewhere between 9 and 13 ap's

typically the extra-large rooms we drop a poe switch directly into the 
room because the 50m cat-5 jumper on the end makes the distance from the 
idf an issue, and it overall helps reduce the number of ports we have to 
provision out that far.
