Questions from poking around Cacti view of network?
by Kenny Richards 16 Sep '15

16 Sep '15

I was going through the graphs/data available via Cacti server and had few questions. 1) What are the Rainier and Tacoma PTP links for on Baldi? Both are showing no traffic recently, are they for future growth? 2) There are three PTP links at Paine I was curious about. I'm guessing the 'Monroe' link is really Bart's client node. But is the Shoreline and 'Bruce' PTP links purpose? The Shoreline link is showing lots of traffic, is that the uplink from the Westin? 3) There seems to be a big hole in the data in the last 24 hours, any idea what happen? Seems to impact all the data sources, so probably something on the server side? Thanks Kenny

Thought you folks may be interested in seeing how MemHamWAN's presentation went this morning. Video of most of the presentation is still processing, but it'll be available on that page as soon as possible. All in all it was a well received presentation with a number of new faces in the audience. ---------- Forwarded message ---------- From: HamWAN Memphis Metro <donotreply(a)wordpress.com> Date: Sat, Nov 22, 2014 at 7:10 PM Subject: [New post] Presentation at Tri-State Repeater Association Meeting To: ryan.e.t(a)gmail.com ryan_turner posted: "This morning, Ryan K0RET, Michael KK4IOH, and Cliff NS4B presented to the Tri-State Repeater Association public meeting about their operations in partnership with Tri-State.

902 MHz Band Plan? Hardware?
by Ryan Elliott Turner 21 Nov '14

21 Nov '14

Hey folks, I'd love to get rolling on testing some 900 MHz gear here in Memphis. I've got a few high-level questions about it, though, and I'd love to find out what others have already settled. Do we want to do sectors and multiple channels? UBNT sells a AM-9M13 that looks pretty slick; 120 degrees, 2x2 mimo; spec sheet here: http://www.streakwave.com/mmSWAVE1/Video/AirMax900Sector_DS.pdf Mikrotik sells a metal 9hpn that's 27 dBm @ 11Mbps to 24dBm @ 54 Mbps (500 mW transmitter), but that's single chain. From what I read, dual chain MIMO mitigates about 3dBm of noise, which may be worthwhile. These devices don't play nice between vendors, though, and I think the preferred dual chain 900 mhz device is the UBNT XR9. We'd lose TDMA by going with this but gain another chain. Thoughts? Apparently the ARRL band plan is pretty outdated and unrecognized ( http://www.aracc.org/33cm900mhz.pdf ). Around here, we have an organization named SERA that has specified a 900 MHz band plan; it is available at the following URL: http://www.sera.org/pdf-files/SERA%20902%20MHz%20FUP.pdf So, here we've got - 922<=f<928 - 910<=f<916 (it says ATV...) And that's it. So, if we were to sectorize, we don't even have 3 channels to use here. Thoughts? Looks to me like omni, TDMA, and single 5 MHz channel (911-916?) is the best way to go for this. -- Ryan Turner
