- U-NII Low (U-NII-1): 5.15-5.25 GHz. Power limited to 50mW
- U-NII Mid (U-NII-2): 5.25-5.35 GHz. Power level limited to 250 mW. Subject to Dynamic Frequency Selection (DFS, or radar avoidance)
- U-NII Extended 5.47-5.725 GHz. Power limited to 250mW. Subject to Dynamic Frequency Selection (DFS, or radar avoidance)
- U-NII Upper (U-NII-3): 5.725 to 5.825 GHz. Power limited to 1 watt.
What if you have have a dozen APs all with a power level of 1 set via RRM? If the AP's channels are dispersed throughout the U-NII low, mid, extended and upper bands, then theoretically the max outputs could be anywhere between 50mW to 1 Watt.
I would love a table or chart that displays the power settings and dBm values for all the model numbers under the CUWN product line. Heck, if I ever have the time, maybe I will write it up and post it for y'all to reference.
Tim,
ReplyDeleteHalving the power Twice (-6dB) does NOT necessarily half the size of your cell. That's what the math says... but not always what happens in the real world with walls, corners, etc.
What? Cisco hasn't published your power to dBm chart?
Well then you ought to make one up to share.
Thanks for the post.
Keith
