Your statement confuses me. Yes, there are EIRP maximums, but what I was saying still holds true. On one side alone, a higher gain antenna will listen to the remote side better, compensating for lower transmit power.
That's why Canopy 5.2 is lucky to go 2 miles, yet you can achieve over 20 miles staying within 36 dB EIRP by using say an 8' dish on both sides. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com -------------------------------------------------- From: "John Rock" <jo...@wirelessconnections.net> Sent: Sunday, March 08, 2009 6:56 PM To: "'WISPA General List'" <wireless@wispa.org> Subject: Re: [WISPA] 3.65 ptp > EIRP is equivalent in measurements... > > John Rock > Director of Operations - Senior Engineer > Wireless Connections > 166 Milan Ave., Norwalk, Oh. 44857 > ACCessing the Future Today!! > ofc. 419.660.6100 > cell 419-706-7356 > fax 419-668-4077 > http://www.wirelessconnections.net > This transmission and any files attached to it, may contain confidential > and/or privileged information and intended only for the named recipient. > If > you are not the intended recipient, you are hereby notified that any > disclosure, reproduction, retransmission, dissemination, disclosure, > copying > or any use of the information or files contained is strictly prohibited. > If > you have received this transmission in error, please notify the sender by > reply transmission and delete this electronic mail. > > > -----Original Message----- > From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On > Behalf Of Mike Hammett > Sent: Saturday, March 07, 2009 4:48 PM > To: WISPA General List > Subject: Re: [WISPA] 3.65 ptp > > Lower your transmit power, duh.
