RE: [smartBridges] RF coverage plots

[Tom Haynes]

The software used is called Radio Mobile and is free. It can be downloaded here: http://www.cplus.org/rmw/english1.html It is one of those programs that take a little time to really get a hang of it, so I decided to perform that function for everyone :-) You can overlay road maps on almost any plot and do lots of other cool things too. When I have to create a new antenna pattern, I find the manufacturers plots and manually create a normalized radiation pattern file. You have to guesstimate a gain reading for each of the 360 degrees. That is why it takes so long.   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Colin Watson Sent: Tuesday, November 18, 2003 8:46 PM To: [EMAIL PROTECTED] Subject: Re: [smartBridges] RF coverage plots   Did you write the software to do this? looks very impressive :) - Just one question, how do you plot the coverage on an antenna - I thought you'd need an anercroic chamber to provide reliable measurements as to the radiated power and it's direction? Or do you just feed in manufacturers values? ----- Original Message ----- From: Tom Haynes To: [EMAIL PROTECTED] ; Wisp-Equipment Sent: Wednesday, November 19, 2003 12:36 AM Subject: [smartBridges] RF coverage plots    When I posted an offer to do some free coverage plots I received many requests. Much more than I expected. Since I need to supplement my WISP income I have decided to start offering this service full time. I think I’ll have to charge based off of time involved since there are several things that take some time. Unless I have to design antenna maps for specific antenna patterns I think I can do most basic plots for $25 or so. Here is a list of my new offerings.   PLOTS: RF coverage (example: http://tomhaynes.net/images/13dbYagi_net.jpg ) RF interference from APs on same frequency Link evaluation (example: http://tomhaynes.net/images/link.bmp ) Topo with roads (example: http://tomhaynes.net/images/topo_color.jpg and topo_net.jpg ) 3D relief LOS view (example: http://tomhaynes.net/images/view.bmp ) Stereographic views (require red/blue 3d glasses)   Email me at [EMAIL PROTECTED] for more info
