I have successfully used TPC to set a minimum power level in dense coverage areas which eliminates low power areas and provides consistent coverage.
Here is an article that talks about the UNII-1 power reduction and the FCC Guidelines, http://www.cisco.com/en/US/products/ps11983/products_qanda_item09186a0080bbfd1c.shtml Jeff Paynter DHTS Network Services Duke Medicine From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Jim Florwick (jiflorwi) Sent: Friday, September 07, 2012 9:10 PM To: [email protected] Subject: Re: [WIRELESS-LAN] setting TX power levels By the way, power level 1 will likely be fine to get started. It is very hard to over power 5 ghz you have a lot of channels to work with. Setting the TPC minimum for 12 dbm will prevent the automatic algorithm from going to low.

In a particular high density coverage area we been requested to set the TX power levels to 12mW and 25mW for the 2.4/5.0 bands respectively. I've calculated that a setting of '4' should provide the 12 mW setting for the 2.4 but I'm somewhat confused about the 5.0. It appears that the max power in the 5.0 differs when using UNII-1 channels vs. UNII-2 channels vs. UNII-3 channels. Do I have this correct? ........thanks in advance...................J Jamie Savage | Senior Communications Technician | University Information Technology 010 Steacie Science Building | York University | 4700 Keele St. , Toronto ON M3J 1P3 Canada T: 416.736.2100 x22605 | F: 416.736.5830 | [email protected]<mailto:[email protected]> | www.yorku.ca<http://www.yorku.ca/> York UIT will NEVER send unsolicited requests for passwords or other personal information via email.
