5Ghz Wifi Antenna?
« on: April 28, 2020, 09:33:22 am »
Hi
Can someone recommend a Company who produce 5Ghz Antenna with an wide Beam width?
For a quick research I found an with 17° Beam width.
Thanks

Indoor or outdoor?

How wide is wide?  What is the application?  MIMO?

Look at Mars Antenna. Ubiquiti or Mikrotik make some sectors (90-120 degrees).  And maybe L-Com, too.

The must radiate Down 4 Floors to have Wifi in the Garden.
No Mimo because I want mount 2x far away from each other.

Something like a Ubiquti AM-5G17-90,  90' sector. small, and could be mounted at a downward angle if you get creative. I've used these before too for small areas but still directional coverage of 60~90 degrees:  https://www.l-com.com/wireless-antenna-24-58ghz-10-dbi-dual-polarity-panel-antenna-n-female-connectors   Or perhaps one of the many square panel style antennas out there.  At 4 stories up, anything with some amount of directionality and gain will work, but absolutely has to be pointed toward your garden else the signal will just fly over the top, off to the horizon (a vertical omni would be useless).

Just be sure to correctly waterproof whatever you get if it's at a non-standard mounting angle. Some panels have drain/breathing holes and stuff.

Its a typical angled Roof.
I would like use the hill and the House of the other Side as a reflector. The good think is I can use 1W at that Freq. insted of the 200mw of the indoor freq.
Your Antena have 2 Ports and my AP 2 to. I need to have a Antenne for the front and a for the Back Yard if possible.

I know this is not what you are asking for, but I would instead consider getting multiple access points instead of trying to get one centralized AP to cover the entire area. A few brands make AP's that are suited to outside use. I personally use the Mikrotik wAP ac, and have 4 installed in the house/garden to cover the entire place easily and well. They can use POE so you just need to pull one cable from your patch board to the mounting point.

Well one cost  ~500€ - 1000€ each. I need a certified one for my phones.

Using the two anntena ports on a MIMO router, but with different anntenna locations covering multiple areas generally doesn't work that well.

What do you mean "certified"?  I'm not familar with the requirements in your area?  The wAP ac does have settings for each specific country.  I use that model as well.

You need 1W transmitters at both ends for that to be useful.

Idont know if its a MIMO one. The have just 4 Antenna on the Site.

To work with the Phone. If not the Accu get drained in 2h than 2Days.

This makes little sense to me, and you really need to clarify why this would be an issue. I don't see how your AP type will influence the battery of your phone getting drained.

 ;D its simple. The the AP often send Packets the the Phone the must Wake up every ms.
Now the phone maybe receive a packed very second.

That's MIMO. Bolting random antennas on it is only going to make things worse.

What exactly is this 'certification' and why does your battery last only 2 hours when my phone lasts four or five days on wifi?

There are power saving thinks who can be adjust to let the phone sleep the most time and not consume much energy. With a conventional Hotpot where this Option are not exist in the public you cant tweak the Hottspot to be that power efficient. Sure with "other brands" who are not certified you maybe get the same results if you have the same options but if it not work the will say: "fuck you".
Now I could make a complain to fix that problem. Zyxel send me a custom FW over who 2 Settings could be change who are not changeable for the default FW and who are needed.

Sounds a lot like either a scam, snake oil, a misdiagnosed problem, or faulty configuration.

Any decent AP allows you to set beacon rate.

Considering this is the first time I have ever heard of this problem, and the entire world seems to be able to get good battery life on their phone with wifi enabled on standard access points, I am inclined to believe this is either a phone problem, a misdiagnosis, or user error - and not some strange 'certification' issue on the WiFi AP side.

For reference, here's the settings for my UniFi APs (like EUR100 each):

Both DTIM period and UAPSD are available.

Can you  set the DTIM to 5 and Guard Interval to long (or what the setting is)?

DTIM to 5 is possible, guard interval is automatic.

Guard Intervals (GI) - 802.11n/ac WLANs support “long” and “short” waiting
periods between transmitted symbols (data). Although a short GI is desirable, UniFi
APs automatically toggle between “long” and “short” GI depending on the WLAN
performance.

Maybe if someone is in my area we can make a test with my Phones how long it run on that AP and the Zyxel one. It would be very interesting.

Running 4 MikroTik wAP ac's at home with 3 phones and 4 tablets, never had a battery problem that wasn't from an old battery or an app gone crazy.  Nor with the Netgears and Ciscos before that.   Nor with the newer Ciscos at my various places of work.  None have any changed wi-fi parameters, all default.

The recommendation for your needs would be a separate AP for each area you wish to cover.  As mentioned separating MIMO antennas doesn't work.  The MIMO algorithms are not setup for that and expect to the see the signal on all antennas to be able to do their math. This should not be confused with plain diversity antenna switching which is not used anymore in modern MIMO AP's.

When did you swap the Accu on the Phone the last time?
I just follow the Instruction to be compliant.

I guess Cisco Phones work best with Cisco APs.  :-DD

Like others I have no idea what you're on about. This is a problem apparently none of us, or the other millions of people around, have. Perhaps fill us in on your phone and what 'certification' is needed.

The year is 2020. They use MIMO. When we say they use MIMO, you should probably listen.

You are chasing the wrong problem - either your AP is junk (seems semi-likely, it is consumer gear) or your phone is junk (also likely). Messing around with putting the wrong antennas on a device is not the solution to whatever problem you're having.

I often read complains about the Phone and that the Accu drain very fast.
