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

VOTE: East Tiger Mountain Hardware
by Bart Kus 29 Jun '15

29 Jun '15

Hello, East Tiger Mountain has been on the air for about a month now. It was partially setup with test hardware, since we weren't sure it would work. This test hardware is not appropriate for running the site on a permanent basis. For example, the dishes don't offer enough shielding, so they interfere with each other. Because of this, we've had to keep the ETiger-SnoDEM link offline. Here is the list of permanent hardware that would go @ ETiger. We have a trip planned for July 11th to deploy it all. *Description** * *Price** * *Qty** * *Subtotal** * ARC-DA5830SD1 2ft MIMO Dish @ Microcom $99.99 2 $199.98 Microcom shipping $60.66 1 $60.66 UDR235 RF Armor dish shielding @ RF Armor $99.95 2 $199.90 RF Armor shipping $40.61 1 $40.61 RB921UAGS-5SHPacD-NM 2W MIMO modem @ Baltic $131.00 2 $262.00 MW-RPSMA-NM-1M RP-SMA Patch Cable @ Baltic $9.95 4 $39.80 Baltic shipping $16.03 1 $16.03 GRAND TOTAL $818.98 I've also donated a server for ETiger out of my own pocket, so that'll be getting installed on July 11th as well. Microsoft should be making a matching donation of at least $340 for it in the next quarterly reimbursement cycle. We have a cash balance of $882.75 in the bank, $162.97 in PayPal, and an unknown balance (~$400) on the CC that needs to be paid still. Key Bank has locked us out of the CC due to us canceling the checking account there, so we're trying to get access again. --Bart

East Tiger Mountain cell site on the air
by Bart Kus 22 Jun '15

22 Jun '15

Hello, We put a new cell site on the air this weekend. It's @ East Tiger Mountain, and radiating @ 240 degrees (Sector 3) only. It's linked directly to the Tukwila datacenter, and has a second link to Snohomish DEM ("Paine"), but that's not yet configured for routing. This site is 1500ft higher than our existing Mirrormont site, and will serve to replace it. It's superior location and superior connectivity are a double-win. Mirrormont has been re-configured to be on the Sector 2 frequency temporarily so as not to conflict, but will go off the air at some point in the near future. If you're in the coverage area try to give it a go and report back! --Bart

Hello, Does anyone have the tools to put connectors on single mode fiber? (cleave, epoxy, polish, test) --Bart

If you cant find someone local, I know a Fiber Comm tech here in Portland(actually I think he owns the company). Id assume he can do most fiber related things but only if it can be done from here. If its something that can be mailed that might work.

HamWAN via passive reflectors
by Bart Kus 06 Jun '15

06 Jun '15

Hello, Today I participated in a HamWAN field test for the upcoming Field Day event @ Luther Burbank park. During the testing, a couple very interesting working RF paths surfaced. Here is the most impressive one: We had setup a dish at the northern tip of Luther Burbank Park, and aimed it at downtown Seattle (around Columbia Tower). We picked up a signal from Baldi-S1! The measured distance (time of flight measurement) was 67km. This means the RF was bouncing off of downtown Seattle and heading all the way out to Baldi by Enumclaw! The data throughput measured was about 1.2Mbit each way average, peaking at 1.5Mbit. We moved the dish atop the hill at the park, pointed it at Baldi through a narrow opening in the closer hill ridges, and did a follow-up test. The measured distance (time of flight measurement) in that direct test was 56km: an 11km difference! The measures aren't very accurate, so the 3km error compared to real physical distance is within the expected error range. Keep in mind that 3km is only 10 microseconds in terms of RF signal flight. Feeling inspired by this astounding Baldi result, we decided to test a reflected RF path to the Capitol Park cell site: We pointed the dish at a random hillside across the water from Luther Burbank, and picked up Capitol Park @ up to -73dBm. Bouncing off this hillside we got 3.5Mbit download and 5Mbit upload speeds to the Internet. I guess the lesson here is: If you don't have a direct path to a HamWAN cell site, perhaps you can try playing with some indirect reflected paths to get connected! --Bart
