But WiMax was supposed to be great with interference because of the magical “HARQ”.
HARQ my ass. So you started with around 100 ms latency, and with HARQ retries, it could go to double or triple that. But they tried to convince us that latency didn’t matter, it was jitter that mattered, and WiMax had nice constant latency. NOT! So I had a system I couldn’t sell to gamers and couldn’t sell with our VoIP service.

Otherwise I question the “magic” of “LTE modulation”, once you try to use it in dirty spectrum. Oooooh, 256QAM. Like we haven’t been doing that for years. I put it in the same category as “3.65 GHz goes through trees”. Only if the noise floor is really low, and then it’s not the “S” part of SNR, it’s the “N” part that’s magic. Maybe I’m missing something, but I’m not wanting to spend big bucks (and a big power budget) to use LTE in 5 GHz. Maybe if there’s some killer antenna technology, but I think that’s what Medusa does too. Not that it is any better on price or power consumption.

A Telrad eNB might be "only" $7k, but you'll be north of $9k by the time you figure out all the licenses you need. I'd be curious about a 3.65 Medusa, but I wonder if I can set TDD parameters that will line up with our existing LTE frames. -Adam On 9/24/2018 3:45 PM, Ryan Ray wrote: It's gonna be on display in Vegas. I'm not even in USA so the CBRS stuff isn't really affecting us right now, but when you start looking at 9k per ap you could get some nice LTE instead. It's just surprising being 2k more than the 5ghz pmp450m. Especially with the cost of the SM being higher as well, but maybe the 450b 3.65 will solve that? Time will tell I guess.

I guess nutty is in the eye of the beholder. But if it’s really available “soon”, I’m a little surprised, I was afraid they would wait to see what the FCC did with the PAL auction rules. Also whether the industry decided that CBRS is only for LTE devices, even for fixed. And I thought Ubiquiti had trademarked the term SOON™. Anyway, I think something like LTE or cnMedusa is going to be necessary for CBRS, especially with the cost of paying a SAS vendor for each location and the cost of acquiring PAL licenses, and then only getting 10 MHz channels. You don’t get much capacity from 10 MHz of spectrum unless you have all the fancy tricks like beam steering and bidirectional MU-MIMO, and of course at least 256QAM.

The ones I designed are 24v and 48v. We have only CMM4 boxes with the Planet switches which I use LC the hybrid cable comes from Besttronics. We have a #12 stranded pair in each of these. I have to have transtector Part#1101-626 at top and bottom to meet our surge protection compliance. Since those sites have been installed I have had zero issues. Seems that 3.65Medusa has made us change to a more direct connection so my box design will have to be modified. All of the Orange tag cables will have to be removed since the packet flux will not support the new power requirements Here is one design we have plans to deploy next week. <image003.jpg> On 09/22/2018 05:05 PM, Mike Hammett wrote: Are most people using SC or LC at the top of the tower? I want to use LC most everywhere I can, but I understand the advantage in SC on a tower where it's easier to work with larger things. What's the next bigger enclosure? Could you put something like this on a swinging panel where I could run a trunk cable into it and then plug individual patch cables going to each radio? Maybe easier on you if you just make it work with something else on the market, like these panels from FiberStore where someone can just get whatever panel they want (LC\SC\whatever)? https://www.fs.com/products/68962.html The goal is to emulate one of these: https://www.raycap.com/wp-content/uploads/DC6-48-60-0-8C-EV_320-1318.pdf https://www.raycap.com/wp-content/uploads/2018/04/DC6-48-60-18-8C-EV_320-1315-1.pdf Power and fiber in one box, transition from trunk to the ground to the radios.

Just a mechanical thing to solve. But patch panels have cutouts for couplers. And different couplers need different size holes in the part that holds them in. So if someone could tell me which coupler will always be needed, then this is easy. Otherwise I have to offer a variety of coupler options and that multiplies my part numbers etc etc. Happy to do that but not if I only sell 1 per month.
