Re: [WISPA] Best system for a new WISP
Hello, Maybe my math is off this morning, for lack of coffee but 2286 Kbit does not equal 22000 Kbit (2.286 Mbit does not equal 22 Mega bit.) which is what I thought I saw at first glance. So if that was KBYTE (which I think it is) instead of Kbit (Kb vs KB) 2286 KBYTE x 8 = 18288 (18.288 Mega Bit) Which is certainly impressive considering the fact that its 10 radios away, and 8 hops as the traceroute shows! But it is Still a bit above half the 30 or 35 Mbit you were previously quoting. -Michael Lonnie Nunweiler wrote: It is TCP. We do not use UDP since it gives a reading that will never be seen by a customer doing an FTP download. We are looking at building in iperf so we should be able to do tcp or udp tests in future. I have a network from Valemount, BC to McBride, BC that has about 100 km of repeater distances. The shot is split in half with mountain shots at each (43 km each) and about 5 km from each mountain top to the POP in each town. We can pull over 20 mbps from POP to POP.

Both are Linux systems with 1 GHz or better processors that we use for firewall and bandwidth control.

I was reading just a couple months back about a WISP operator that had a severe problem. Just a few yards away, maybe 300 feet, another guy put up his tower. I think they were both on 2.4 GHZ, and someone suggested a different AP that would not even be detected by conventional systems. Something about nonstandard bandwidth, channel spacing or coding. I really feel that stealth is best here. These other guys have been in business for a while and could cause trouble that I do not need. Lee Trango does make a good product. I still have 2 Sunstream AP's in use. They are like Timex watches. I'm using Star War boards. A little bit more than
Re: [WISPA] Weird problem - 20 seconds latency and other oddness
If this was rf noise, Arent hamm operators allowed in 2.4 with higher power limits? Could this account for the 5- 10 mile affected area? -Michael David E. Smith wrote: Okay, Scriv and I are stumped on this one. Over the last couple of weeks, we've started seeing some very odd oddness on a few of our 2.4GHz POPs. Not all, just some. Here's what appears to be happening: A couple times a day, usually during business hours, something somewhere generates a massive amount of noise. Connections which report an RF noise of -90 start showing noise levels of -60 (or worse in some cases), as reported by our StarOS access point. If it really is RF noise, it's very broad, as it's simultaneously hitting five or six POPs, some several miles away, but all at the same time. The towers are all running StarOS on Mikrotik RouterBoard hardware, with a mix of Orinoco and Prism cards, some with amps, some not. Some have sectored antennas (180 degrees), some have omnis. Between them, the towers cover just about the entire 2.4 spectrum (obviously, one channel per access point, but we're using at least channels 1, 4, 6, 8, and 11). Those towers are basically identical to several other towers that aren't affected. The other really really weird part is the crazy latency. Pings to the APs themselves are reliable, and our backhaul links (5.3 and 5.8 GHz) don't seem to be affected. And pings to our end-customers don't seem to get lost, they just take their sweet time getting there. While the event is happening, I've seen pings that take in excess of twenty seconds to complete their round trip. 64 bytes from 10.232.175.130: icmp_seq=7 ttl=62 time=27239 ms (I think that's my record. In that particular test, there were no packets lost, they just took a very long time to get there.) I've checked or replaced just about everything I can think of in our network that might cause something like this, and frankly, I'm stumped. I don't think it's a network problem (traffic bursts or similar) because of the weird bursts of RF noise. But that'd have to be one helluva burst of noise to do what it's doing - affecting every channel across ten miles at once. I can go into more detail on any part of the network if you like, though I think all the likely-relevant details are covered here. Help!
