I would like Mikrotik to consider a new type of BaseStation AP
- Something that is possibly modular (where antennas can be mounted to other antennas to form an array of small spot-beam sectors.
- Something that falls under FCC point-to-point higher power rules
- Something that functions simular to a beam-steering phassed-array (where the system acts list a point-to-multi-point system).
Vivato (now out of business) did have two models of phassed-array outdoor BaseStation APs (rated at 2,000 wireless clients per Vivato BaseStation). I still have 16 of them. When Vivato went out of business , I switched over to Mikrotik - because firmware updates for the Vivato were old & dated. Note - I had both Google and the DOD performed testing on my Vivatos phased array BaseStations 10 years ago. They told me they were BLOWN-AWAY because of the long distance (10 miles) they could acheive with a stock notebook computer. Each set of 4 Vivatos (360 degree coverage) were 10 miles apart and they were able to roam from Vivatos to other Vivatos 10 miles away when both Google and the DOD performed their almost month long testing. Each Vivato had around 100 slot-beam antennas. The Vivatos were able to receive & transmit from/to multiple wireless clients at the same time. Their technology used beam-steering with MAC switching on the slot-beam antennas. Depending on where a wireless client was, a client might have a dozen antennas per Vivato they were connected to. Also, the Vivato BaseStations would slightly delay the tx of some antennas to form a directional beam (similar to how a radar system works in a fighter jet - no moving parts - beam steering).
Another company just announced a BaseStation (Ubnt) which is claimed to support the following; 5 Gbps real Aggregate wireless throughput , MU-MIMO , 1,500 wireless clients , 10-Gig Ethernet interface (some serious stuff here !!!)
If the Ubnt BaseStation performs even close to what my Vivatos were doing , then this is a real serious contendor for high-density high-volume high-throughput system.
The current issue today with trying to achieve this with current Mikrotik hardware is that it would require a 120 foot tower physically saturated with almost 100 narrow-beam high-gain overlapping Point-to-Point APs and dish antennas to do the same thing.
I would like to see a Mikrotik system that can achieve the same thing.

Sounds interesting. But is part of the evolution in wireless also not that now the spectrum is saturated where 10 years ago is was hardly used? I mean, my first Mikrotik 2,4Ghz 802.11b outdoor AP on a 8dBi omnidirectional had no problem to communicate with my laptop at some 300-400 meters away. And that communication was the sending of an e-mail.
Now I am glad my new dual chain 802.11a/b/g/n/c laptop still has a connection to a 18deBi dual chain 90º sector with Netmetal 30dBm radio some 50 meters away. And I am not interested in sending an e-mail, it needs to be a 4K streaming full duplex Skype video conversation (I am a bit exaggerating).....
10 years ago in a 2,4Ghz scan I'd performed all I saw was my own AP..... Now a scan reveals some 100+ radios..... Ok, we have 5Ghz now, but that is sort of similar. My 5Ghz AP's easy pickup 20 other AP's.... and there must be several hundreds of CPE's communicating with them.
I must mention though we have one 'alien brand' AP working on a village that is also full of 5Ghz AP's and users, but they work with their own protocol on the 5Ghz band. They work with 4 antenas on one AP and then each of these 60º sectors are overlapping to get some 200º reach. The AP works on 10Mhz wide channels but each antena has its own frequency slightly different from the others. Now the OS switches connected CPE's to that sector with a good enough signal to supply the top PHY rate achievable that carries the least traffic. The result is that each of the connected clients have no issue to reach the OS limited top download of just over 30Mbps and sustain that for prolonged times. Basically each sector can sustain a full 30+Mb download to a single client thus the AP can do 4 at once.... in a 10Mhz channel! Low latency, sustained speed...... Try that with a Mikrotik 20 or even 40Mhz normal Wifi solution....
Over the same village we have 2 more AP's, both Netmetal and working 5Ghz NV2 or plain 802.11ac but 30Mbp is only possible if that client is the only one using the AP and only peak speeds. This is with -45dB signals all duo chain 20Mhz wide channels.....
So yeah, there are better ways of doing wireless.....
