I do not completely agree on that.Local only is a waste of time. Syncing multiple towers is critical.
I have one tower that has 5 backhauls and 5 AP's. Its amidst a valley with many more towers from me and others.
This tower of myself needs 5 x 40Mhz channel and 5 x 20Mhz channel. Each available channel will also receive some signal from distant radios.
I can make the whole thing work by using high to very high gain antennas to create narrow beams and very high signals (-35 to -45dBm range) and by using the professional dome or carrier class antennas from RF elementes for my AP's that are all shielded pretty much from co-tower interference and remote channel interferences. Clients are fit with antennas that at least receives -70dBm but preferrably below -65. But sometimes we need to change frequencies just because some tool decided to use same as me or very close to it. It's a hell of a puzzle to find a new frequency. I always also need to look at the other end not to interfere with radio's on my other towers....(And some clients are 'looking' at one tower but get signal from another tower at the same strength if it was an omni-cpe)
If I could use sync only in this tower it would make my life much easier because I could basically use just 2 (1x 40 and 1x 20Mhz band) or 4 frequencies instead of the 10 different ones I need now. If I could do one other tower of mine the same again I would free a lot of spectrum. Since I have 60+ radio's all in theoratical 'hearing' range where the competition adds another 40 or so spectrum is short. Off course it would be better to have more towers of mine sync'd but I can't do them all anyway since some are inter connected to at least two other towers of mine so I still need to play with the frequencies.
But the puzzle would become much simpler by one fully sync'd tower, much but less simpler with 2 towers, more but even lesser with 3 etc. etc.
Radwin has a local solution where gps can be added.I do not completely agree on that.Local only is a waste of time. Syncing multiple towers is critical.

Are there any products currently available in the fixed wireless market today local sync only? I think every form of fixed wireless sync in use today is GPS based. There must be a reason for that.
Maybe I should rephrase that. Anything other than GPS based sync as an end-game is a waste of time.
yep. 1588v2 as most widely-used and efficient version of PTP.I wasn't real sure what you were meaning by PTP, but I see that it's just an updated version of 1588. 1588 is fairly common.thats why aside GPS sync and NTP is PTP introduced to fill gap between.
usually nodes in Telco - support Both GPS and PTP for obvious reasons. and control nodes and routers - rely on SNTP aswell.
(https://en.wikipedia.org/wiki/Precision_Time_Protocol meant. other PTP protocols exist, but Wastly less popular, as i can see)
you must be new to Telco(outside NA), then.What legal and political issues? Most equipment can use GPS and GLONASS.
If GPS in devices in your jurisdiction is a crime, I think you have bigger issues ahead of you than ROS. GPS and GLONASS are supported in most every mobile phone.yep. 1588v2 as most widely-used and efficient version of PTP.I wasn't real sure what you were meaning by PTP, but I see that it's just an updated version of 1588. 1588 is fairly common.thats why aside GPS sync and NTP is PTP introduced to fill gap between.

and yes its "fairly common"(in fact - MORE than GPS sync in telco), but NOT supported by RouterOS aswell as GPS sync, yet.
you must be new to Telco(outside NA), then.What legal and political issues? Most equipment can use GPS and GLONASS.
in many installations - both having Navstar enabled or even having GPS-enabled devices in infrastructure - is crime.
same ~ about GLONASS in NATO-controlled countries/regions.
its also somewhat not EMI-resistant much(atleast civilian channels) to be used in surprisingly big portion of installations.
so, no, GPS isn't "magic bullet" or even thing you can rely on. its simply to use(if you had support for or had Rights to use it), but its only advantage, which not worth it, basically, cuz 1588v2 imply same 10ns sync accuracy without all that headache.

Still more emotions that facts......can we're strip emotions or personan offences and talk bout topic and facts:
1588v2: no need for extra-silicon, simpler code, no IP and political issues, less "blackboxed" things in solution
gps sync: "simplicity" (ony When/IF someone invest TREMENDOUS efforts into implementing support of it)
same 10ns accuracy, same usage, comparable adoption(some sites - used both).
so far, all BTS/base stations, fiber backbone, p2p and p2mp RF links - used 1588v2 as far as i can see, including those with GPS-sync enabled hardware and firmware and disabled GPS sync.
you opinions - maybe differ from mine aswell as experience, but thats not give you "supernatural" and exclusive ability/super-power to both opress others or dictate/manipulat mikrotik devlopers about their priorities and roadmap.
if you like - mikrotik products - fine. if you don't - there is plenty of other vendors on market.
you had you opinion, you shared it, you heard. and even had feedback(sometimes "nicer" than mine and less polar), but there is NO need(in my opinion) to out-cru/shot about again and again and again, trolling others.
The whole thread is based on ... nothing. MT never did GPS and never built a radio. UBNT hired a crew of radio experts from Motorola to do this radio. It is far superior to standard WiFi based radios. You get most out of small channels and it performs very good with other radios near by as it has better neighboring channel rejection.Still more emotions that facts......can we're strip emotions or personan offences and talk bout topic and facts:

To what are you actually referring? A specific radio? Or just their radios in general? And what is the connection to the sync issue in making this last remark?UBNT hired a crew of radio experts from Motorola to do this radio. It is far superior to standard WiFi based radios. You get most out of small channels and it performs very good with other radios near by as it has better neighboring channel rejection.
Airfiber as said in $subject. The other radios are atheros based.To what are you actually referring? A specific radio? Or just their radios in general?

thats basically all of them, enumerated, plus portion of cellphone infrastructure gear/stations manufacturers.UBNT first tried GPS sync on their AirMax radios and failed. They hired away some of the Motorola crew and got GPS sync right with their AirFiber line.
Cambium does GPS sync on Atheros chips as does Radwin. I know others have as well. Mimosa is doing it with Quantenna chips.

so as you can see "GPS sync" isn't "magic bullet", or widely-adopted in telco/it.
how much "afwully large" was translated to "common people's math" ?thats basically all of them, enumerated, plus portion of cellphone infrastructure gear/stations manufacturers.UBNT first tried GPS sync on their AirMax radios and failed.

That's an awfully large percent of units shipped in our industry.
I would guess well over a third, possibly even a half.how much "afwully large" was translated to "common people's math" ?thats basically all of them, enumerated, plus portion of cellphone infrastructure gear/stations manufacturers.

"7%"? "12%"? i don't think its bigger than 20%. ~avg
and several GPSsyn-enabled/aware devices/solutions - installed/used without it as i explained above/before for reasons told before aswell and some others.
Besides, it is not even true. PTP (1588) is only a way to distribute time sync over ethernet, and those installationsHowever, I'm done with this GPS vs. 1588 thing.... it's taking away from the core issue of Mikrotik not having sync.
yep. regardles how its carried - over fiber, copper, RF or open air lazer links - its "just works".Besides, it is not even true. PTP (1588) is only a way to distribute time sync over ethernet, and those installationsHowever, I'm done with this GPS vs. 1588 thing.... it's taking away from the core issue of Mikrotik not having sync.
contain a reference clock that itself is usually synchronized to GPS. So you can call a PTP installation GPS synced as well,
PTP is only a distribution mechanism not a synchronization source. Similar to a distributed PPS line.
thats quite short and quite old article which despite highlight basic issues and conclusions about sync and PTP, referenced only for obsolete version of 802.1AS and PTP IEEE 1588v1. IEEE1588v2 had Much better parformance and had Resolved most of issues restricted its usage as main PTP for both 3G, LTE and 5g networks aswell as long-link fiber and open air laser links
