Hi
How many access points can be stetted for deferent interfaces under same routerOS?
For example I have 4 wireless interfaces and going to enable access point mode for each interface. Is it possible?
Thanks in advance
as far as i know - there is no limitations.
EDIT:
except - interferance from each device etc. etc.
but you can set up PC with with 5 RB18 totaling n 40 wreless AP’s 
It means that I can install 6 wireless interfaces , set access point mode to each, attach 6 sectoral antennas and got the clustering solution like canopy and so on?
yes, no problem.
But not yet have advanced feature like
TX synchronizing between sector antenna ?
Right, normis ?
High Regards,
Andrei
why do you think that this is something advanced and needed?
Simple, Usable frequency are not something that infinite.
Yes, frequency is nearly infinite, if you could tap to hundreds GHz freq,
but its costly and have many drawbacks.
IF we need more sectors / tower than avaiable frequency (, like
what’s happen in GSM industry, this feature is god send

think interference 
from your interfaces
Its, why we need synchronization in transmit , receive.
Thinks, why Canopy could be used in array, located in adjacent space ?
Answer ???
AP TX syncronization, they always transmit in the same time, and always
receive in the same time. So no self generated interference then )

So what are you think
Does the RB32 board with it’s daughterboard rb564 able to work in that scheme:
6 r52 cards in one wireless router with 6 sectoral antennas (closes 60 degree), to provide powerful access point up 30 km radius in 2.4 ghz?
what exactly do they receive, if at this time noone is transmiting, only receiving? at this moment there is no data to receive then please explain better. i think the feature is already there, you just can’t explain it in proper way
AFAIK The Motorola Canopy system uses Time Division Multiplexing - which is what I think this thread is hinting upon when saying things like ‘TX Synchronization’. They have taken it a step further allowed multiple APs to co-ordinate.
MT might be able to achieve something similar by using their NStream polling and some kind of inter-router communication?
Yes, Canopy's are using time division duplexing (TDD) and time division
multiple access (TDMA).
Easily speaken they do not send, when a second AP/radio is receiving
(from clients, or other backhaul devices), and vica-versa.
This reduces interference. The larger units have a GPS receiver as a time
source.
Is something like this possible with a MT and let's say 4 radios
(4 x 90deg. sector) as a AP? Do they "communicate" and kind of
"poll" the client data synchronised?
seandsl
isn’t this the same thing what Nstreme does with polling?
Give us more details on how nstreme works, and we can tell you
if it's the same. g
If you have a Routerboard with 4 radio interfaces for 4 backhaul links
running nstreme ptp, does it kind of "synchronise"?
seandsl
NO.
We found from real life experience.
Even if we spacing the channel 40 MHz (skips 2 full channel) apart,
if card A transmitting, the data flow in card B would be reduced.
High Regards,
Andrei
that is why Nstreme2 should be used.
normis,
nstreme2 is fine for 1 (one) backhaul link, what about a scenario
with more than one backhaul/ap radio in one box/routerboard??
Referring to your postings which I do not see as an "answer to the question"
I will assume that a similiar configuration isn't possible with MT.
Regarding bandwith issues a nstreme link would be fine in many
situations but "more bandwith" is not the answer to all questions.
seandsl
nstreme is not just about more bandwidth. it also does all of the things you are talking about in this topic. and about multiple nstreme2 links in one box - why not?
