- vezycash 11y agoThanks. I always assumed one could only get such distance with WIMAX
- noselasd 11y agoOr with a number of proprietary technologies(of which the airFibre is just one of many) - backhaul using point to point radios is used a lot in telcos and there's numerous (expensive) products available.
- lordnacho 11y agoHow do you aim it at the other end? It's 100km away?
- amazon_not 11y agoGPS.
- emilw 11y agoFor whoever downvoted the GPS answer, RTM. Please do, it's highly informative and very cool technical and educational material. If you refuse, please insert the F into the appropriate abbreviation and start this paragraph from the beginning.
- jonpaine 11y agoPlease make sure your loops converge. I read and modified this paragraph 3,984 times and then crashed.
- dingaling 11y agoNot sufficient. Civilian NavStar/ GPS has a 95th percentile accuracy of 7.5 metres and a best-case of around 2 metres. That's more than enough to miss by several dozen dish diameters at 100km.
- KaiserPro 11y agoat 100km it doesn't matter. Even with a beam divergences of 0.5 degrees 7 meters is literally a piss in the ocean: Look at the polar pattern here: http://dl.ubnt.com/datasheets/airmaxyagi/airMAX_900MHz_YAGI_Antenna.pdf http://dl.ubnt.com/datasheets/airmaxyagi/airMAX_900MHz_YAGI_... more importantly you have to fine tune the alignment anyway.
- amazon_not 11y agoMain alignment with GPS and then finetune to get maximum performance. At 100km the main signal lobe is quite large, so being off by a few dozen dish diameters isn't large enough of an error to not to be able to get started.
- wahsd 11y agoSame way you aim a Satellite dish to a satellite that's at least 35,000 km away.
- Scoundreller 11y agoUp to 1.2gbps and up to a 100km link. I don't think you can get both.
- jlgaddis 11y agoI'm guessing you haven't actually used one of these units? You'll be lucky to get half of either of those values. FWIW, note that, unlike the majority of the network equipment industry, $UBNT's throughput numbers are aggregate values (i.e. equal to transmit + receive). 1.2 Gbps in $UBNT-speak, for example, means 600 Mbps transmit and 600 Mbps receive -- whereas an 1 Gbps NIC can transmit 1 Gbps and receive 1 Gbps simultaneously (yet we don't call them 2 Gbps NICs).
- oakwhiz 11y agoIn practice it's more like 10 to 20 km for max throughput.
