The Poynting antenna discussion thread

quetiano said:
Good day to all reading this.
I have a question regarding the Poynting a-xpol-0002-v2 and the Huawei B315 but under my specific conditions.

The modem is situated in my bedroom, and outside is a carport with those wave like metal sheets as the car port roof.

The Huawei B315 modem was included with those antennas that connect behind the modem and those screw into the modem antenna ports.

Currently, in the modem setup website page, I have 4 green bars out of 5 green bars for signal, and I get download speeds of 22 Mbps (2.2 mb/s) to 40 Mbps(4 mb/s) in speed testing via the mybroadband speed test (http://speedtest.mybroadband.co.za) , using either the Johburg or Cape town server. Using Cell C LTE, its stated that we can get up to 69 Mbps on ideal network and coverage condition, and I get between 22 Mbps to 40 Mbps. I would love to squeeze out and enjoy higher lte download speeds if possible.

My question is, by using this Poynting a-xpol-0002-v2 antenna, can I get a stable high speed connection with an increase in download speed, since I am already sitting in the 4 green bars out of 5... or shall I stick with the basic included antennas that were included with the modem ?

Current perimeters for network signal which vary :
rsrq varies from -5dB to -8dB
rsrp varies from -90dBm to -91 dBm
rssi varies from -69dBm to -69 dBm
sinr varies from 18dB to 13 dB




According to the below info...


RSRP (dBm) - (Reference Signal Receive Power) - measure of the signal strength.
-------------------------------------------------------------------------------------------
more than -79 dBm - very good signal strength,
from -80 dBm to -90 dBm - good signal strength,
from -91 dBm to -100 dBm - poor signal strength. Need for an outdoor antenna or finding a better location of the modem
less than -100 dBm - very poor signal strength. It is necessary to use an outdoor antenna


RSRQ (dB) - (Reference Signal Received Quality) - measure of the signal quality.
-------------------------------------------------------------------------------------------
more than -9 dB - very good,
from -10 dB to -15 dB - good,
from -16 dB to -20 dB - bad. Need for an outdoor antenna or finding a better location of the modem
less than -20 dB - very bad It is necessary to use an outdoor antenna


SINR (dB) - (Signal to Interference plus Noise Ratio) - measure of signal quality with respect to
-------------------------------------------------------------------------------------------
interference.
---------------
more than 21 dB - very good,
from 13 dB to 20 dB - good,
from 0 dB to 12 dB - bad. It is necessary to use an outdoor antenna
less than 0 dB - very bad.It is necessary to use an outdoor antenna


RSSI - Received Signal Strength Indicator
----------------------------------------------
more than -73 dBm - very good,
from -75 dBm to -85 dBm - good,
from -87 dBm to -93 dBm - bad. Need for an outdoor antenna or finding a better location of the modem
less than -95 dBm - very bad. It is necessary to use an outdoor antenna



...my above network measurements seem ok but hoping that with the outdoor antenna, it would increase dramatically?


Thanking you guys in advance !

Hey dude
what Antenna did you buy?? i want to Achieve
RSRP -80
RSRQ - 10
RSSI -72
SINR 20

i have got 2542 Rand in my Bank. i want to buy External Antenna's i am sick of 1-2 Bars signal on LTE
 
Competition to Poynting?

Hi,

is there a competing vendor and product to Poynting Direct?

i am having trouble with the service and quality of work, and am getting no where. would rather change to somebody else.
 
Hi guys,

What's the difference between the Poynting XPOL-2 LTE antenna vs the A-XPOL-0006 (The Telkom one for the B315's)

Which of the 2 is a better antenna? Is omni direction a worth looking at? I think I know where my tower is and it may be direct line

XPOL-2 = 9dbi gain,
XPOL-0006 = 11dbi gain

XPOL-2 = 698-2700 MHz

XPOL-0006 = 1710-2700 MHz

I'd love to see side by side comparison of real world figures for these antennas using different service providers [MENTION=463718]Newsfeed[/MENTION]
*EDIT* seems the extra frequencies offered by the -2 are not used in SA?

** Not sure how accurate this is:
MTN = 1800Mhz + https://www.frequencycheck.com/carriers/mtn-group-south-africa
Vodacom = 1800Mhz + https://www.frequencycheck.com/carriers/vodacom-south-africa
Telkom = 1800Mhz + 2300Mhz https://www.frequencycheck.com/carriers/telkom-south-africa (this link only shows 2300 but I know Telkom supports 1800 as well).
Rain = 1800Mhz + 2600Mhz: https://mybroadband.co.za/news/cellular/230925-vodacom-reveals-rain-roaming-details.html

Any suggestions where to buy the adapters to attach a xpol-0006 to a Huawei B618 router?

Wiil do. I've ordered from them in the past so hoping all goes to plan again this time.

Quick feedback on this. Zasttra contacted me the day after I ordered to let me know the supplier was out of stock and wanted to refund. I asked if they had an ETA on new stock and then, a couple of hours later, they let me know they could source from a different supplier (but there would be a delay). The items arrived in good order last week.

However, if anyone else is looking for an adapter to connect a B618 to a Poynting antenna, don't get these, they're the wrong type (male, not female). :mad: If only gender could be self-selected when it comes to adapters like these... Oh wait, there's probably a different thread for that. :ROFL::X3:
 
Hooking up the xpol to a B618-22d causes a big increase in RSRP but also a drop in SINR. Anything I can do to improve the SINR?

I managed to get a decent signal by, wait for it, turning the x-pol to have it facing away from the tower, i.e. the back is pointing towards the tower. I have no idea why this works, but this gives a significantly better signal than the other way around.

Reflections. RF is black magic. Don't try to understand it.
 
Hi Guys,

Currently i have a Poynting LPDA 92 antenna that im using on a Huawei E3131 usb modem on a rual location (no line of sight) and its giving me between 6-25% signal strength on Cellc/Vodacom roaming (WCDMA/UMTS/HSPA+).

As far as i understand one can greatly improve your LTE signal strength by using 2 antennas cross polarized.

1) I would like to know if i can get/expect an improvement on my 3G signal by using 2 antennas, cross polarized on a lte 3G compatible router (lets say the B315, as i think it supports 3G as well) or would i be wasting my money on the extra antenna and router (+-R2500)?

2) Does anyone have an idea of the time frame on when the sub 800mHz bands will be allocated for LTE, as that will surley benefit us in the rural areas!?

Thanks a lot!
 
Where can I buy one of these aerials to work with my Huawei router. The one that came in the telkom lte deals
 
I have a client who lives on a farm with direct line of sight to a tower which is about 40km away. Is there any viable solution I could offer to get him Internet?

Being able to confirm line-of-sight to a tower 40km away is in itself no mean feat. That's gotta be some seriously flat countryside!
I presume you mean a tower/base-station which is known to carry services from one of the cellular operators. It would be good to verify that fact by seeing what networks and services are available at the tower itself. Also that there really isn't anything closer.
Assuming there is 3G or 4G service available at a base station to which you have LOS, the viability of getting service 40km away would depend on the actual signal strength available at the client's premises. The best way to assess that is using proper equipment such as a field-portable antenna and a signal-strength analyser. You best bet is probably be to approach Poynting themselves and ask them to come out and do an assessment. They have the right equipment and if the signal is viable, they can then supply and install a suitable antenna system. If you were to try this on your own, you could spend a lot of time (and money) without getting much of a result.

At that range I would think you will probably be looking at some kind of parabolic dish antenna system rather than a wideband LPDA antenna system based on something like the Poynting LPDA-0092. As an example of somebody doing something similar at 15km range, have a look here - different country, but similar situation. That whole thread may be of some interest to you. Rigid mounting and good alignment will also be fairly critical at that range, which is another reason to let somebody with the right equipment set it up and make it work.

With all of that said, if you shin up on the roof at the client's premises and if you then you see even 1 bar of 3G or 4G service, your prospects of getting viable service using an antenna system are instantly improved.

If getting internet service from one of the terrestrial cellular networks isn't an possibility, your next best bet is probably to look at getting internet service via satellite.

Thanks for the feedback, I will have a chat to them and see if there is any signal whatsoever and contact Poynting as suggested.
 
What is the A-xpol-0002-v2 like for MTN LTE, I get 1 or 2 bars and I want to boost speeds?
Also if you have a stronger connection by using an antennae and are always connected because the connection is via fixed router will the local tower give you any priority over other users?
