Mikrotik, there are any news about improving NV2 protocol?
Today we can’t have more than 25Mbps aggregate on an 20Mhz AP with 30 stations
(5Ghz n/ac)
You could implement TDD with a ratio of DL/UL.
The most widely used in networks PTMP is 75/25.
All combined with a GPS Sync or Internatl Sync dramatically improve aggregate bandwidth (80-90Mbps) and make reliable connect 70-80 stations in real environment.
Are you working on it? Any of your engineer is studying something? Do you have changes in the air? Give us some more news… your wireless market for wisp is dying
I don’t believe that nv2 will be improved, nothing has improved from a long time ago. I limit the number of stations to ~20 because of high ping and small speed.
It would be pretty cool, NV3 !!
Today’s customers are more and more, few frequencies, the spectrum is more dirty, and customer bandwidth trend increase (competitors increases)
Urge then, see if Mikrotik wants to develop the radio technology for WISP, or remain, leave give me the comparison, as the Dude (stationary for years)
If yes, unfortunately they must also listen to the voice of the people, our needs.
TDD with Custom Ratio DL/UP
GPS Sync, or another sync system in same tower
Modulation mechanisms more robust (why slow down rate when the are inactivity? require more time to find better modulation when traffic is generated)
Methods of checking error more detailed (for example drop radio packet)
Better support in nLos o NLOS (is now a total disaster)
Hardware RF filter
Errors correction in engineering design of hardware .. sorry but even today with some rain I was burned additional NetMetal (incoming from sticker)
But if none of this is in your thoughts, then better to gear up with something else
Yes epmp is a system which is considerable/comparable. MT should look at it and implement some features like gps. The SMs are higher quality than sxt light. The door mechanism of SXT is not as good and we see damaged ethernet ports as it is narrow to insert ethernet cable.
Epmp has no .ac (even not announced) so you will likely replace it in the near future. 100 cpes on one wifi based ap will give bad performance regardless how they tune the mac.
for PTMP in NV2 case, we are interested to put more CPEs to an AP
And on UBI, how may clients can you put to an AP, and what is the max troughput of the AP?
Ok, 2km, so your test is a PTP.
But how can you say me on PTMP ? This is the big problem…
In my experience I see
ubnt airmax: 50-60 stations on AP with an aggregate of 35-40Mbps
mkt nv2: 45 clients on AP with a aggregate of 30-35Mbps (personal experience in a very good scenario)
difference?
ubnt has very fantastic built-in QoS (if match with your needs)
mkt when are near the limit (also stations per AP) start lowering bandwith and spike (also if AP is with 6-7Mbps in use)
epmp: on AP with 70 stations with an aggregate of 80Mbps
pmp450: on AP with 150 stations aggregate of 90-100Mbps and very low latency and not frequent spikes
Mikrotik can has the potential of improving his wireless for Wisp but, as this thread say, no one single comment by Mikrotik employees
Matches with what we see. MT is good for low density. Epmp does scale much better esp. as gps allows frequency reuse. Pmp450 is best when price is no problem.
So we install MT at small sites and epmp when we expect higher numbers.
MT has still the advantage of ROS and the flexibility to put/exchange boards.
Same experience here. Two APs. No NV2, just straight 802.11n (2.4GHz). 35 - 45 clients each, terrible jitter (5 - 200+ ms) and CCQ variation (15% - 90%). Noise floor -109 to -111 which is the best possible.
Client furious. Bad for my reputation.
Mikrotik, can we expect some hard work being put on this? Anyone? Normis?
Why you have NV2 disabled? This topic is about NV2.
Enable nv2, set TDMA to auto. 35-45clients is too much for AP. Especialy on 2,4Ghz.
Move clients to 5Ghz with NV2
