Re: [WISPA] Pathloss 4
Daniel, Most professionals use Pathloss. Most if not all commercial carriers use Pathloss I've been engineering Paths for 8 years and swear by it. Its worth it Knowing how to use it properly is priceless. I'm not in here much any more because some of the members like to go against the grain and try to re-invent the wheel with their profound knowledge and lack of experience. Pathloss is a winner. I've used it over the yrs to design networks in over 10 major US markets. 100-400 paths per market. Its a great product. You will need to know how to use a GPS. The software ( Pathlosss ) is a great tool but it should be used in coordination with a process of eyes on/ hands on . Nothing is more valuable than Driving the path and terrain to see what the software is showing you on paper. The software isn't going to show things like new construction. It isn't going to show you that 80' tree sitting on the highest terrain feature blocking your path with gear at 60' on the tower/rooftop.

Re: [WISPA] Pathloss 4
What can it do that Radio Mobile does not? I have been engineering microwave paths since 1978. Back in the day it was curved path profile paper and counting elevation lines on a topo map. I have used about a half dozen software products over the years, including the original on line version from ComSearch. I have NEVER had a path perform worse than my estimation.

Re: [WISPA] Pathloss 4
Chuck, I am probably one of the biggest supporters of Radio Mobile, love the software and agree with you. What Radio Mobile does not do well is things like reliability factors for hot standby and if you build in diversity antennas. For most WISP's this is not an issue. To that end, Radio Mobile does do well because you can get 10 meter resolution terrain data and now with the working clutter model you can do pretty well with that if you buy the data (1 km resolution is free). Radio Mobile also has issues above a certain frequency due to the fact that the Longley Rice model does not work that high. One big drawback to any RF tool is the learning curve and your knowledge of the basic RF theory itself. Knowing the theory helps you to recognize what the software is doing and why you might get errors. Any of them have a time commitment to become proficient and then use the tool to it's full potential. But as you said, it's certainly much easier than doing it from paper maps counting contour lines :-) I wonder how many people on this this even know how to do that?

Re: [WISPA] Pathloss 4
Most of the tools use the old ATT long lines long haul and short haul availbility factors that were generated for analog radios. It is the opinion of some that digital radios do not need to need nearly as much fade margin as the old analogs. I would have to say, that our experience with some 60 mile paths using cyclones, I would have to agree with that opinion.

Re: [WISPA] Pathloss 4
I don't know the answer to that question. I have always pondered the issue of fade margin on digital paths. If you factor in an error checking in both the modulation methods and the TCPIP stack, you can deal with minor fades and in many cases you might not even notice a short fade. At that point however you would still need to have a tool that deals well with temperature inversions and rain fade, because if you do get a fade in those situations it more than likely will last long enough to be noticed even on a digital path. But in most cases for WISP's in today's usage patterns they won't run in to those situations. The one thing that will start to push us back to engineering like analog paths, will be the migration towards net applications that are a more constant demand on the pipe and not bursting in nature. Things that would be sensitive to packet resends will start to show a weak backhaul with fading issues.

I've used it over the yrs to design networks in over 10 major US markets. 100-400 paths per market. Its a great product. You will need to know how to use a GPS. The software ( Pathlosss ) is a great tool but it should be used in coordination with a process of eyes on/ hands on . Nothing is more valuable than Driving the path and terrain to see what the software is showing you on paper. The software isn't going to show things like new construction. It isn't going to show you that 80' tree sitting on the highest terrain feature blocking your path with gear at 60' on the tower/rooftop.

We use it every day for running path profiles and microwave reliability estimates for customers... I would say we definitely got our money's worth.
