[WISPA] 1/2 size channels and tx power
Just curious about something. If' I'm using an R5H card with a 54meg tx power of 21db, then switch it to 1/2 size channels (10mhz), will I still be limited to 21db txpower, or something closer to 25 (the 24M full size channel tx power)? I'm pretty sure the txpower is tied to the modulation, not the size of the channel, but I've seen mention of getting better signal strengths under smaller channels (spectral density?). -- Randy Cosby Vice President InfoWest, Inc 435-674-0165 x 2010 http://www.infowest.com/ WISPA Wants You!

Better signal due to noise floor change. 10Mhz has been a life send. Steve Barnes Manager PCS-WIN RC-WiFi Wireless Internet Service Character cannot be developed in ease and quiet.

Re: [WISPA] 1/2 size channels and tx power
Hi, In my experience, when changing from 20mhz to 10mhz channel size, I see a +3db in signal strength on each side of the link. This is with no other changes, we leave all the power settings at default. Travis Microserv Randy Cosby wrote: Just curious about something.

Re: [WISPA] 1/2 size channels and tx power
Only problem I've got with 10Mhz (or 5Mhz) is that a vast majority of laptops cannot see that, and it kills our hotspot capabilities. Beyond that, yes, it's fantastic. -Original Message- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Steve Barnes Sent: Wednesday, October 21, 2009 1:08 PM To: WISPA General List Subject: Re: [WISPA] 1/2 size channels and tx power Better signal due to noise floor change. 10Mhz has been a life send.

Re: [WISPA] 1/2 size channels and tx power
Drop a MT 433A in place with a 2nd R52 as your hotspot on an Omni Down lower on the tower. Then you have a dedicated Radio for Subscribers secured on a 10Mhz channel and a Hotspot Radio that if it has some goofy laptop in a semi trying to connected at -88 it doesn't kill all your subs.

Re: [WISPA] 1/2 size channels and tx power
Makes sense. Same power in half the with is like doubling the power Jerry -Original Message- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Travis Johnson Sent: Wednesday, October 21, 2009 12:08 PM To: WISPA General List Subject: Re: [WISPA] 1/2 size channels and tx power Hi, In my experience, when changing from 20mhz to 10mhz channel size, I see a +3db in signal strength on each side of the link.
