Decision-Making on Router Upgrade: Huawei B535 to B628, B715, or B818 for Tmobile Network

Hey everyone

A request for help in making the final decision about the choice of the router. I've spent the last two weeks on the problem I'm writing about

I use mobile internet in the tmobile network in Kamieńczyk near Wyszków. I log in to the BTS station with the number 49677068. L4G 2x15 db antenna. Huawei B535 router with working 800 2100 aggregation. The dominant band is 800 Mhz, the signal from the 1800 and 2100 bands is weak. The share of capacitive bands in the aggregation used is small, but noticeable. The RSSi parameter on 800 2100 aggregation -72 db, and on 1800 2100 aggregation -87 and at the same time it means a decrease in transfer parameters. The 800Mhz band always turns out to be crucial.

I am considering changing the router to one that supports three bands in the spring, hoping that a more modern router will strengthen the 1800 and 2100 signal in the aggregation. The 15db antenna does not seem to be weak, and looking for a stronger one, you can find Chinese crap. I am considering the following models:

Huawei B628 - three bands, enough to aggregate 800 1800 2100 which is available in my area - disadvantage, the need to cut the micro card to nano. Change sma to ts9 by a bit.
Huawei b715 - three bands, without any changes, but difficult to buy.
Huawei B818 - four bands, card unchanged, change of antenna tip - opinions say that it works well in difficult terrain (and this is the area of ROD Kamieńczyk)

The question that comes back is whether changing the router will pull in and amplify the 1800 and 2100 bands until a strong adjacency is formed, assuming the antenna must remain unchanged.

In addition - how modern and powerful is the B715 router today

That's it in a nutshell, I hope that all relevant information has been provided. I would appreciate feedback from more experienced people.

Regards

I haven't seen any tests on the B535 here. Giving RSSI to LTE has no meaning. It's a pity to comment on the antenna at all, the B535 is a good choice for such stations, the LTE2100+1800 bands work at 25MHz, so they are assumed to be faster than 10MHz on LTE800, the range to which most customers log in. Therefore, the basis is to ensure optimal signal parameters at 1800-2100MHz for the B535. With about 2 km to the BTS in these conditions, the purchase of a directional antenna dedicated to this band is essential.
And for today, and especially in the spring, I would check Play and see if the Nadkole station works, just for comparison.

Hello,

There is no band 2600 in stonecyk at all. That's it.
Play has exposed me enough in my life that I don't want to hear about it. That's two.
I write my post based on observations and tests. The data is not random. It's three.
The newsgroup's favorite sarcasm is redundant is four.
I wish you health, that's five.

The answer suggests a lack of understanding of the topic. It doesn't answer my questions

Regards

The answer is the most consistent with what you wrote, or rather with the fact that you wrote nothing sensible. Starting with your observations and tests you've left to yourself, so what's the sarcasm claim?
You asked questions without presenting any specifics regarding the signal parameters on individual LTE2100, LTE1800 and LTE800 bands and evening speedtests performed on the B535 with these antennas. In addition, LTE2100 + 1800, LTE2100 + 800 and LTE1800 + 800 aggregation, so no one here can help you.
Changing the router will give little or nothing, LTE capacitive bands and obtaining signal parameters on them that allow the QAM256 modulation to be activated is the basis and the only reason to change the B535 to B818 / B628. But this requires cooperation on your part, for which you do not show the slightest desire.
The approach to PLAY is not even worth commenting on as much as the choice of this thing pretending to be an antenna.

Were you always this smart? How much superiority is in you, congratulations.

What superiority? Asking basic questions about the parameters of the signal and the speed on them is a standard in the selection of equipment for the mobile internet, this is physics and only hard, specific data and the knowledge of how to interpret them allow you to get the right solution.
You think you don't need to introduce them, don't show them, but don't blame anyone for not helping you.
And what is your problem I have already written, only LTE capacitive bands and improving the signal parameters on them will allow you to get better results, today we do not even know what the parameters look like on them with your antennas, so there is nothing to discuss further.
