I’m planning to setup a 6 SXT G-2HnD AP PtMP configuration 1x6x6 (1 tower x 6 sectors x 6 frequencies ) 6 SXT G-2HnD AP to be a base station those AP will be mounted on a tower this tower will be a triangular tower fabricated out of steel angles or pipes maximum height will be 6 meter the tower will be erected on top of a concrete building 18 meter height.
what is your recommendation for me to accomplish this setup successfully.
You will have self interference and nothing will work.
Yes I know then what should I do to avoid it ( self interference ) I’m planning to use same SSID for all APs on same tower.
I need every sector to be aligned to maximize the coverage within that sector and minimize the noise and interference from all other sectors and areas. So what is your suggestions
Use vertical separation for at least half the APs, 3m at least. So two groups of 3 APs installed 3 - 5 meters apart.
Add Metal shielding for every AP so that APs cannot hear other APs louder than -60dB RSSI.
Use 5MHz channels. You can’t do that if you are talking to consumer devices.
Turn the power down on all of the SXT APs to the minimum required to service your desired area.
Use down-tilt to make sure your APs are not hearing more noise than necessary from outside your desired service area.
Use N-stream or N-Stream2 so that you will have fewer clients screaming at the APs at the same time and interfering with the other client’s ability to be heard by the other APs.
You will still have self-interference issues. Your APs will hear reflected signals from all of the other APs and your CCQ will probably be in the toilet when you have more than 10 clients active. A Canopy solution with GPS sync where every AP talks at the same time and listens at the same time could work.
Even better idea, 2 2.4GHz APs and 4 5GHz APs using real shielded sector antennas with shielded cavity to house a small dual polarity routerboard. If you try to do it all on 2.4GHz, you will still have problems.
Something like, but not necessarily exactly : http://www.kpperformance.ca/sector-antennas.php
Way not deploy half as Vertical only and half as horizontal only…
Use standard 20MHz channels, and do all the other good suggestions like spacing, and shielding.
You’ll also want a good channel plan so that those overlapped channels are facing opposite directions.
If there’s noise drop to 10MHz channels.
This all assumes you have a fairly quiet 2.4GHz band, which is hard to find in my area.
Also to design the solution effectively you left out one of the biggest variables…
What do you expect to deliver to the customer in terms of latency/throughput?
And why the same SSID? Seems like a management headache to have 6 AP’s with the same SSID. I usually incorporate Azimuth and Polarity into my SSID’s so the installer knows which AP to look for and on what polarization.
Do client laptops and smartphones work on 5mhz channels??
Do they sense Nstreme or NS2?
What if we plan a wifi-zone??
No.
No.
A hotspot? With all the APs on the one tower? No. You will self-interfere until nothing works. The client laptops and smart phones will hear the tower just fine. However, the tower will struggle to hear the clients which will all be screaming for attention because they cannot hear each other.
You could setup small ground level hotspot APs (like the RB751/RB951 devices) all over the coverage area as long as the tower doesn’t see all the noise from them. You could then use MikroTik devices to backhaul each hotspot AP to the tower.
With the level of expertise your questions indicate, it may be less expensive to find and hire a local consultant to come design a setup after doing an on-site site survey and more fully discussing your needs in person. You keep waving your hands around and not actually describing what it is you want to do. We are just making wild guesses about what it is you want to accomplish.
