Hello
I recently bought unlimited internet in T-Mobile with Huawei B525s router, but the signal is quite weak. I established that the router connects to the BTS 2 km away (Świdnik, Lubelskie ul. Piasecka 22). In auto mode (the router aggregates 800 + 1800) parameters not the best [align = center: df9acb3e5a]
and the speed it achieves is DL: 15-18, UP: 5-7. Forcing only 800MHz band parameters unchanged [align = center: df9acb3e5a]
however, speeds much worse DL: 10Mbps UP: 7Mbps. On the 1800MHz band the parameters are much worse [align = center: df9acb3e5a]
and DL speeds: 18Mbps UP: 0.7Mbps. At first I thought to buy 2xATK-10 but on the 800MHz band terribly low speeds. Hence my question whether it is better to buy an antenna up to 1800MHz and use only this band or choose an antenna for aggregation 800 + 1800MHz to fully use the guaranteed 60Mbps. If the aggregation antenna, which one?

No guaranteed 60Mbps. T-Mobile does not guarantee minimum speeds, offer for 65 PLN / month with DL up to 60Mb / s or for 49 PLN / month with DL up to 20Mb / s. What you will achieve on LTE1800 + 800 will show a BTS test on your direction as long as the aggregation starts and it is not given to you forever. Speeds depend on the load on the BTS.

I know that nothing is guaranteed with mobile internet, but when I signed the 60Mbps contract I was hoping for something more than 18Mbps. Otherwise, I would sign a contract cheaper up to 20Mbps. A router without an external antenna can aggregate 800 + 1800 bands, with 800 as the primary one and 1800 as the spare one. I want to improve link stability and increase speed. Will ATK-504 handle band aggregation and is there any difference between ATK-502?

You can always call t-mobile and ask about the possibility of changing the offer to 20Mbit / s. I don't think they should be doing the problem. Before that, do your bts tests.

Tests done. Near BTS speeds are reaching the discussed 60 Mbps. I did not look for favorable hours and I did tests today (Sunday) at 15. What should I do to get such speeds at home and what antenna should I use to improve the signal?

You can possibly take with a 5m cable LMR240 it will be cheaper and less cable loss. Remember that in LTE nothing is forever, but the signal is weak, and the speed on a good Sunday is a lightly loaded station.

Hello, let me join the topic. I am the owner of the Huawei B528s router with internet from T-mobile, unfortunately in my town is very poor coverage I was thinking about buying an antenna to improve LTE. Below I attach screenshots from Hmanager. I wonder why after the change from LTE to 3G the range increases and the internet speed increases (speed test changes from download speed 3.6 to 7.8). Please help me to choose the right antenna and to direct it to the appropriate BTS. My place of residence is Balczewo in Kuj-Pom.

LTE800 from BTS-a Networks Modliborzyce, very weak signal, low SINR and speed. Put it out the window and show how the signal parameters on the LTE800 look, and DL / UL on the speed test, it may be overloaded. LTE1800 and UMTS2100HSPA + DC on 3G from BTS at Laubitz 19 in Inowrocław. Residual signal on LTE1800, not bad on UMTS2100. In addition, it works on DC, i.e. DL up to 43.2Mbps and is faster than on LTE. Finally 3G on free UMTS900HSPA + with BTS-a Błonie 6. In general, do the LTE1800 and LTE2600 test with B528 outside the window. LTE2600, LTE800 T-mobile and LTE1800NW operate on BTS Błonie 6 and Jagielońska 22 and aggregation of these LTE bands. BTSs with LTE800 alone such as Modliborzyce are usually overloaded. Better chances for better speeds from those in Inowrocław, both on LTE and 3G with UMTS2100.

Thank you for the quick reply.
Tests carried out with the router outside the window. First LTE 800 + speed test. Others also, in addition, speed tests on the Auto setting are the latter (st) and on G3 -2100 are the latter (st). Does the antenna help at all.

LTE800 is already mentioned Modliborzyce, as expected, despite the improvement of the signal clogged band, not worth attention. LTE1800 this time a weak signal from LTE1800NW in Wybranów. On LTE2600 is T-mobile from Pl. Klasztornego 2. The aggregation with BTS at Błonie 6 as the basic LTE1800 band and LTE2600 or LTE800 from it joined. Weak signal, adequate speeds. In the home T-Mobile, such BTS jumps are the norm. In such a situation, it is necessary to purchase an external broadband antenna operating in the 800-2600MHz band, e.g. 2xATK-504 from TELKOB. You'll set up Inowrocław and on it further tests of bandwidth and aggregation and setting it to a specific BTS. As it will be difficult to predict. Speeds depend on many factors, it will definitely improve and stabilize the signal on all LTE bands, you will use it in case of 3G on UMTS2100HSPA + DC.

Thanks again for the info and valuable advice. When displaying the router in other windows, it was still connecting with BTS at the hospital on ul. Poznańska in Inowrocław, but there were no major changes. It remains to buy the antenna and further attempts. After buying and testing, I'll let you know what and how. Thanks again.

FAQ

TL;DR: On T‑Mobile’s “up to 60 Mb/s” plan, fix weak Huawei B525/B528 LTE by using a wideband 2xATK‑504 and aiming LTE1800/2600; “Speeds depend on the load on the BTS.” This FAQ helps T‑Mobile LTE users choose antennas, test bands, and stabilize carrier aggregation. [Elektroda, matek451, post #17494237]

Why it matters: The right antenna and band strategy can turn unstable LTE into consistent, plan‑level performance for home internet users.

Quick Facts

T‑Mobile Home Internet plans: DL up to 60 Mb/s (65 PLN) or up to 20 Mb/s (49 PLN); no guaranteed minimum. [Elektroda, matek451, post #17494237]
Recommended hardware: 2xATK‑504 wideband (800–2600 MHz) to improve/stabilize LTE and enable multi‑band use. [Elektroda, matek451, post #17500621]
Keep coax short: 5 m LMR240 lowers cable loss and cost versus longer runs. [Elektroda, makosuu, post #17497915]
Real‑world check: Near‑BTS Sunday tests reached ~60 Mb/s; test close to the tower first. [Elektroda, miś35, post #17496908]
Caution: LTE800‑only cells are often congested; target LTE1800/2600 or aggregation when available. [Elektroda, matek451, post #17500621]

What’s the best external LTE antenna for a Huawei B525/B528 on T‑Mobile?

Use a broadband 800–2600 MHz set, such as 2xATK‑504 from Telkob. It strengthens and stabilizes LTE800/1800/2600 and also helps 3G fallback. As one expert put it, “broadband antenna operating in the 800-2600MHz band, e.g. 2xATK-504.” Align it to a multi‑band BTS and test carrier aggregation. [Elektroda, matek451, post #17500621]

Should I choose an 1800 MHz‑only antenna or a wideband antenna for carrier aggregation?

Choose a wideband 800–2600 MHz pair. It lets your router use LTE1800 as primary with LTE2600 or LTE800 added when available. LTE800‑only sectors can be overloaded even with good signal; the expert verdict: “clogged band, not worth attention.” Aim at multi‑band sites for better headroom. [Elektroda, matek451, post #17500621]

Can ATK‑504 handle 800+1800 aggregation on a B525s?

Yes. ATK‑504 covers LTE800 and LTE1800 used by T‑Mobile. An installer confirmed, “ATK‑504 is good, works on every band.” Use the set with your router’s external ports and verify aggregation after alignment. [Elektroda, makosuu, post #17494217]

Will T‑Mobile’s “up to 60 Mb/s” be guaranteed after I add an antenna?

No. T‑Mobile sells plans “up to 60 Mb/s” or “up to 20 Mb/s” without a guaranteed minimum. “Speeds depend on the load on the BTS.” An antenna improves signal and stability, but it cannot remove cell congestion. [Elektroda, matek451, post #17494237]

How can I replicate the 60 Mb/s I saw near the BTS at home?

Stabilize your link with a 2xATK‑504 aimed at a multi‑band site. Prefer LTE1800 as base and allow LTE2600 or LTE800 to join. This setup improves and stabilizes signal across LTE bands. Throughput still depends on many factors, including local conditions and traffic. [Elektroda, matek451, post #17500621]

How do I install and aim a 2xATK‑504 for best results?

Mount the pair outdoors, high and clear, facing the chosen BTS.
Use a short 5 m LMR240 coax run and weather‑seal connections.
Fine‑tune for best SINR, test Auto and per‑band speeds at different times. “Remember that in LTE nothing is forever.” [Elektroda, makosuu, post #17497915]

Why is LTE800 slow even with good signal metrics?

Many LTE800‑only cells run at capacity. Even after improving signal, speeds can stay low because the band is “clogged.” Prioritize LTE1800/LTE2600 or their aggregation when possible. A wideband antenna helps you target those sectors. [Elektroda, matek451, post #17500621]

Why is 3G (UMTS2100 HSPA+ DC) sometimes faster than LTE800?

Your LTE800 sector may be loaded, while UMTS2100 DC can deliver up to 43.2 Mb/s. Tests showed residual LTE1800 signal but solid UMTS2100. When LTE underperforms, try UMTS2100 DC for steadier throughput. [Elektroda, matek451, post #17500409]

Which BTS should I point to around Inowrocław/Balczewo?

Favor Inowrocław sites broadcasting multiple LTE bands. LTE2600, LTE800, and LTE1800 NW run on Błonie 6 and Jagiellońska 22 with aggregation. UMTS2100 HSPA+ DC is at Laubitz 19. Avoid Modliborzyce LTE800 for LTE; it is often overloaded. [Elektroda, matek451, post #17500409]

What performance can I expect 2 km from a BTS with weak signal on B525?

A user 2 km from the Świdnik BTS saw about 15–18 Mb/s down and 5–7 Mb/s up in Auto (800+1800). Forcing 800 MHz gave ~10/7 Mb/s. Forcing 1800 MHz yielded ~18/0.7 Mb/s. Results vary with load and alignment. [Elektroda, miś35, post #17494105]

Can I downgrade my plan to 20 Mb/s if real speeds disappoint?

Yes. Call T‑Mobile and request a change to the 20 Mb/s tier. A forum member noted they should not make a problem switching. Confirm contract and billing impacts, and keep your speed‑test logs handy when you call. [Elektroda, DobryMudzyn1702, post #17494633]

How should I test per band and aggregation before buying an antenna?

Place the router at a window or outside and record LTE800, LTE1800, and LTE2600 readings. Run speed tests on each band and in Auto. Also compare 3G UMTS2100. This approach revealed faster 3G for one user and clarified aggregation behavior. [Elektroda, mac_ino, post #17500490]
