Wireless Coverage/propagation? in Wireless Service Providers http://www.dslreports.com/forum/r22598954 en Wed, 02 Dec 2009 18:01:24 EDT Wed, 02 Dec 2009 18:01:24 EDT Re: Wireless Coverage/propagation? http://www.dslreports.com/forum/remark,22627893 JKM : Thanks for the info. I did finally get some RF plots done. After downloading many different formats I found two that worked. The GTOPO30(30 arc sec-1km) from usgs.gov, link on pizon.org and the The SRTM(1 arc sec-30m) from recordist.com, link on cplus.com, first choice under second heading. ]]> http://www.dslreports.com/forum/remark,22627893 Mon, 29 Jun 2009 11:38:12 EDT Re: Wireless Coverage/propagation? http://www.dslreports.com/forum/remark,22624759 NZFxonet : 1 arc second is about the best resolution you will get.]]> http://www.dslreports.com/forum/remark,22624759 Sun, 28 Jun 2009 17:22:55 EDT Re: Wireless Coverage/propagation? http://www.dslreports.com/forum/remark,22615191 JKM : I've got RM up and running. Also having trouble with terrain data. I borrowed a Verizon wireless usb and spent 3 hours downloading SRTM tiles (1/3 arc resolution) from the first site on the list at cplus.org (overkill I know, I always go for more than I need). The program says the data is missing and won't download from internet despite settings. I'm using the tutorial on pizon.org. Decided I shouldn't have unzipped with WinZip. I had saved the files so I unzipped with 7-ZIP, same thing. Now I am in the process of downloading "SRTM finished 1 arc second" files from USGS. At least these zipped files are 1/4 the size, hope the they work. I can download better resolution later. If anyone knows what I'm doing wrong feel free to speak up!]]> http://www.dslreports.com/forum/remark,22615191 Fri, 26 Jun 2009 12:45:03 EDT Re: Wireless Coverage/propagation? http://www.dslreports.com/forum/remark,22612101 oxygen69 : I've been having trouble just downloading the area terrain data, as it is NOT doing it automatically, despite following the directions of editing the map files, ect....]]> http://www.dslreports.com/forum/remark,22612101 Thu, 25 Jun 2009 21:39:30 EDT Re: Wireless Coverage/propagation? http://www.dslreports.com/forum/remark,22610270 NZFxonet : I still don't get why people think Radio Mobile is that hard?

Does anyone know where to get a spectrum analyzer.. and not 2.4 or 5.8GHz I am looking to scan 1.5-6Ghz? Anything cheaper for a laptop or a place to rent them from?

Ubnt XR3 $150:

My questions is WHEN will the Nanostation 3 be available? If pricing is similar to the NS5 then this could turn 3.65ghz into a very inexpensive band to utilize!
If you live in the US.
Canada sucks for spectrum.]]> http://www.dslreports.com/forum/remark,22609375 Thu, 25 Jun 2009 14:00:52 EDT Re: Hmm not bad... http://www.dslreports.com/forum/remark,22606853 oxygen69 : The Ubnt XR3 is using a 802.11 protocol, but I am looking for 802.16.

Even the cell network goes out here in slow rolling valleys, so I expect LOS to be obtained by most since people are spread out. I cannot see what would be great though for NLOS as 900MHz is noisy in general, and licensed frequencies would cost a fortune. I figure 3.65 is empty by me now so use while available. :)]]> http://www.dslreports.com/forum/remark,22600750 Wed, 24 Jun 2009 00:09:08 EDT Re: Wireless Coverage/propagation? http://www.dslreports.com/forum/remark,22599571 AMD Phreak : Oh also be aware the map i give you won't factor land usage (trees, buildings, etc) so I guess you really won't have a true picture of near line of sight and non line of sight.

I wouldnt use 3.65 for near/non los anyway, personally.]]> http://www.dslreports.com/forum/remark,22599571 Tue, 23 Jun 2009 20:03:31 EDT Re: Wireless Coverage/propagation? http://www.dslreports.com/forum/remark,22599555 AMD Phreak : Post your coordinates here or pm me. Include the following: ap and cpe antenna height, radio specs for ap and cpe, antenna gain at ap and cpe, operating frequency range.

Give me 48 hours or so and I will have a map for you. I can kick out point to point profiles very fast, but getting terrain data for ptmp coverage maps makes the process take much longer. ]]> http://www.dslreports.com/forum/remark,22599555 Tue, 23 Jun 2009 20:00:39 EDT Re: Wireless Coverage/propagation? http://www.dslreports.com/forum/remark,22599466 oxygen69 : I'm not rally framiliar with mit or uni stuff.. maybe you could elaborate a little? :)

I have recently been using www.heywhatsthat.com to model respective tower heights and to see what area can then be seen, but I expect this is mostly a LOS application of the program. I am curious to see any NLOS coverage maps and get a little more exacting idea of the area covered. Now I realize that there are many variables, but assume you are only in a hilly, no tall buildings area in the country. I also understand that the math involved here may take a small mainframe, but if anyone has some suggestions please feel free to say them. :)

I would also like to get some real hardware in the 3.65GHz spectrum to do some outdoor testing, but it is all so expensive and I just want to do real world analysis. Is there anything out there that can transmit 3.65 and receive that can be rented or bought cheaply just for a study of the area? Money is tight now, but hopefully one I get more things worked out it won't be such an issue..

Thanks!]]> http://www.dslreports.com/forum/remark,22598954 Tue, 23 Jun 2009 18:10:31 EDT
