Antenna installation and alignment

I wrote a correction to the post claiming that manual disconnection and reconnection would force re-registration to a different tower (because it doesn't) and provided a tip how to do it correctly.

However I don't think it is going to help in your case. You have strong signal from the close tower and a hudge interference from unknown source. Your difference between RSSI and RSRP is between 26 and 29dB, no matter which antenna is used. In such case I think it will always force to re-register to the tower with overhealming strong signal, no matter how you orient antenna. So I think forget hunting for the fastest peak transfer rates (just to amuse others) and refocus on stability of the connection, so you can always have instant network response (latency, ping). You also need alternative feed, in case of LOS tower failure or overloaded condition. If overloaded, tower will instruct your device to find another tower, giving channel number to look for.

So in other words, once you invested in expensive antennas, position indiviual antennas to a different tower, both in basic vertical aligmnent for good and proven receive diversity.

It could be also substandard device. If you can test it in different location on a goood (proven) installation, or try to borrow another device and see how it works.

Just to check if I understand correctly - are you saying that the difference between the RSSI and RSRP is an indication of the stability of the connection?

How do I go about getting a stable connection (instant network response, latency, ping etc) - what can I do to improve that?

Thanks
 
There is nothing further that you can practicably do. Is there any way to test with LOS to the 100Mbps tower from another location? Just to further the discussion. Do it for the thread! :p

Mmmm not at the moment no.....but I'm working on the Trustees about trimming that tree...... I will get there! .....yes...for the sake of the thread :whistle:

Test on common property! :D

You funny man....yep...I can just picture myself....laptop up the ladder...extension cord for power.....router....spanners....undo antenna....walk 20m to the right on the roof.....hold it in place while getting the router to connect to the new tower.......sounds like a hoot....:D
 
Tell them you're finding a way for the body corp to save money with a new free wireless internet provider. When your tests are concluded, simply tell them the property is unfortunately out of range.

Not exactly. I see from posts that when difference is smaller, people get better speed. There was an article (link posted here) how to interpret these values.

By chosing tower, positioning antenna, but I see you have enough walking on the roof. :)

I is why I suggest to check your router on good installation first to make sure that router is 100% OK.

Back to using my XPOL-0002 as of two days ago. I also sold my spare to Force_za who happens to be in my area, using the same tower. :p

I bugged Force_za for his results, just waiting for photos:

Before - internal antennas

He was getting 24Mbps down and 1Mbps up (not sure with TM or MTN LTE).

I advised him to get Afrihost Mobile due to the XPOL-0002 frequency support.

After - XPOL-0002 installed with LOS

To quote jcheek..."PAYDIRT!" :p

Such a pity when you have views like this but no LOS. :cool:

I've never seen upload speeds like this on 3G. This is 3-4 bars signal. (Location: Athlone, Pietermaritzburg, KZN)

With speed tests like this it's arguable any form of outdoor antenna is needed. I still like to try. ;)

Meet my reincarnated LPDA-0092's temporarily installed at their new owner's premises!

Yup, that's an umbrella stand. :p Pretty innovative if you ask me.

I believe the improvement was logarithmic. :p

I'm waiting for actual numbers but the trial for him obviously surpassed his expectations so he'll make it a perma install soon.

As a technical person I would recommend that all new B593 users first do some playing around with their new modems before obtaining "stronger" "external" "indoor or outdoor" antennas and maybe save the money for data.

Drive around in your area to search the closest tower and do some signal tests on your cell phone.
I say this as most 3G towers has been upgraded with new LTE panels in LTE areas or contact your ISP for info or free survey.

Also note that moving/turning your modem as little as a few milimeters to the left or right can make a big difference if "build-in" antannas are used. I have done many of these sorts of fine tuning in my clients homes and save them money.

I am very thankful that I am very close to a tower and if I had to move I will make sure I have a tower close by in line of sight.
As I am still not fully convinced that these fancy mentioned antennas from poynting are worth the money
or are worth the effort of self install.

Users to far from towers/or no/little line of sight need external outdoor antennas installed by professionals with testing/metering equipment. (Quality installations comes with a guarantee)
Users can try doing it them self but it takes "FINE TUNING" to get true results. (Like installing a dish for dstv)

And while you on the roof make sure you have a safety rope around you... we do want you to report back on self installs.

Oh yes, also remember the stronger the antenna, the more noise it can pick up if not installed properly.
(So outdoor antennas can make matters worse)

I've quoted the above post (irrelevant bits left out) to move the discussion here...
 
I think it's a perfect time to drop this here which jcheek has alluded to in his posts:

Did you notice that you have strong signal outside the building, but inside it fades away. That is because outside there is less interference with the signal.

Buildings and other structures disrupt the signal. If you mount the antenna outside, it offers the opportunity to receive the signal from an outdoor environment which is not prone to the multipath fading experienced in an indoor environment.

There is a 10-20 dB advantage when receiving the signal in an outdoor open space environment as compared to a cluttered indoors.
This together with the antenna gain provides anything between 20-30 dB gain when using an external antenna even if the antenna gain is only 11 dBi (High Directional Antenna (A-LPDA-0092).

Of course it's not feasible to permanently locate your LTE router outside! Which goes back to a point I made previously, Huawei should include the XPOL-0001 + 7m cable with a special edition LTE CPE. :cool:
