I'd say that is a pretty good noise floor for 900MHz... remember this stuff can carry forever
Cordless phones, baby monitors... basically most things wireless can use 900MHz. Then you could be near a paging tower... or possibly a SCADA network out there. Honestly... I'm surprised your 2.4GHz noise floor is that good too Daniel White 3-dB Networks http://www.3dbnetworks.com >-----Original Message----- >From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On >Behalf Of Mark McElvy >Sent: Thursday, September 03, 2009 9:55 AM >To: WISPA General List >Subject: Re: [WISPA] 900Mhz question > >I am curious about 900 noise.
