What is maximunm distance recommended for Room Kit microphone

[RoofusThedoofus]

I can't find a diagram like the ones for the Ceiling microphone that shows a specification of the distance for the room and chairs. I stick to the ceiling mic chart that show installing at 8' high with 14' horizontal range on making recommendations. But I want to make good recommendations for other microphones. 

How far is allowed to specify distance for the Room Kit audio microphone?

How far is the diameter recommended for the table mic 20?

How far is the diameter recommended for the table mic 60?

How far is allowed to specify distance for the SX10 audio microphone?

Thanks for you input and pictures if you have the diagrams.

Here are some numbers about the table microphones. From Cisco's "best-practice.pdf" we find the following instructions about table microphones on slide 7.

• Spacing between microphones should be about 45—60 in (1.15—1.50 m), and a maximum of 45 in (1.15 m) from participants.

So we can calculate the recommended diameter for table mic by the maximum distance from participants:

• 2 x 1.15m = 2.3m
• 45" x 2 = 90" or 7' 6"
