[WISPA] What frequencies not to use
Hello all, I am looking at shooting a 5.x Ghz link through a busy port. What frequencies should I avoid? Thanks Richard WISPA Wants You!

Re: [WISPA] What frequencies not to use
If you can you should use the 5.4 band. Second option is 5.3 and then 5.8 GHz. You don't say the distance so its hard to say to use other options In urban areas we use large antennas and lower the power to narrow the beamwidth. In addition I would use horizontal as there are many consumer products on 5.8 that use vertical Good luck Bob Sent from my Verizon Wireless BlackBerry -Original Message- From: richard sterne wireless.r...@gmail.com Date: Sun, 5 Jul 2009 19:59:02 To: wireless@wispa.org Subject: [WISPA] What frequencies not to use Hello all, I am looking at shooting a 5.x Ghz link through a busy port.

Use a frequency that your spectrum analyzer indicates is NOT in use. richard sterne wrote: Hello all, I am looking at shooting a 5.x Ghz link through a busy port. What frequencies should I avoid?

Re: [WISPA] 900 MHhz accross water
Yep, I've seen that sort of thing. Here's 5.8 Alvarion VL over about 2-3 miles of water. One end is 250ASL on a tower 1/4 from the ocean, the other end is a couple hundred feet from the ocean and probably 50' ASL. The red curve is the SNR. The grey line is the transmit power (ATPC enabled). http://www.midcoast.com/~jp/water58.png Here's 2.4 Alvarion BA-II over water. One end is 20' ASL and 100' from the water, the other is 700' from the water and 100' ASL. Link is about 4 miles. http://www.midcoast.com/~jp/water24.png On Sat, Jul 04, 2009 at 12:03:31PM -0400, Jeremy Parr wrote: 2009/7/4 jp j...@saucer.midcoast.com: 900 works better over water than 2.4 or 5.8. 5.8 is pretty unusable if the antenna is near the water under certain conditions. We usually have to keep the antennas back off the shore to make it work. We see lots of multipath destructive interference fluctuate with the tides on the ocean. Worst case is about a 40db variation. 10-20 db is common with 2.4. 900 is the least affected. You should use SNMP to graph signal of links over water to evaluate how it is performing in your test. This is a 5.8ghz Alvarion VL across four miles of water. You can clearly see where the tide changes. WISPA Wants You!

Then, use some of that wifi spray to prevent future use of the frequency.

[WISPA] Australian regulatory concerns...
have a tentative offer to to some buildout in Victoria Australia, pending the completion of a local project here. But I don't know where to look for their laws regarding unlicensed spectrum, if there is any. Does anyone have any pointers/links for me to research? -- Bradley D.

Re: [WISPA] Australian regulatory concerns...
Title: Charles Galeano - Government Endorsed Supplier G'day Bradley, I can help here. Australian regs are similar to the USA as follows, 2.4Ghz 11 channels 36dB EIRP max 5.8Ghz 4 channels 36dB EIRP max, higher power for specific locations away from the high density populations. 5.470Ghz to 5.650Ghz many channels, 30dB EIRP max with DFS and TPC enabled, some exemptions for lower power 900Mhz is just 916 to 928Mhz allowed with 30dB max We also have 60Ghz exempt within a certain channel size/range plus 70/80Ghz site licensed at little money. www.acma.gov.au site has more detail, just tricky to find. Offlist if you need more detail from me. regards Graham Bradley D. Thornton wrote: have a tentative offer to to some buildout in Victoria Australia, pending the completion of a local project here.
