Many MTS network users are familiar with the problem of an unstable connection in a country house or remote office. Often, the cause of low speed is not a technical equipment malfunction, but the physical distance to the base station or the presence of obstacles such as walls and trees. Mobile Internet sensitive to interference, and even a high-quality router may not operate effectively without proper configuration and placement.
In this article, we'll explore proven methods for improving reception quality, from simple device placement adjustments to professional equipment installation. You'll learn how to set up frequency ranges and what interface parameters need to be changed to achieve the maximum data transfer rate.
Before buying expensive amplifiers, it's worth conducting a basic diagnosis of the current situation. Often, the problem can be solved with competent antenna orientation or changing the network operating mode, which does not require financial investment, but provides a significant increase in productivity.
Diagnostics of the current signal level
The first step should always be assessing the current network status. Standard indicators on the router body or in the web interface often only show an approximate number of "bars," which doesn't provide a complete picture. For accurate diagnostics, you need to log into the device's administrative panel using the IP address. 192.168.8.1 or 192.168.1.1, and find the section with the connection status.
We are interested in the numerical values of the parameters RSRQ, SINR and RSRP. Parameter RSRP shows the signal power level in dBm (the closer to 0, the better, optimally above -90 dBm). SINR (or SNR) reflects the ratio of the useful signal to noise—a critical metric for speed; if it's below 0 dB, the internet will be extremely slow or constantly disconnect.
To obtain detailed information, you can use special AT commands or third-party utilities if your router supports them. In some Huawei and ZTE models, which are frequently used by MTS, detailed information is available in hidden menus accessible via URLs or scripts.
⚠️ Note: MTS router interfaces may differ depending on the model (Huawei, ZTE, Eltex) and firmware version. Section names may vary, so look for tabs labeled "Status," "Condition," or "Network Information."
Optimal placement of the router
The physical location of the device plays a crucial role in reception quality. 4G signals have poor penetration through metal, thick concrete walls with reinforcement, and mirrored surfaces. Placing the router on a windowsill, especially on the upper floors of a building, often yields better results than placing it deep in the room.
Avoid proximity to sources of electromagnetic interference. Microwave ovens, baby monitors, cordless phones, and high-power power supplies can create radio frequency interference, which "jam" the useful signal. The distance to such devices should be at least 1-2 meters.
Antenna orientation also matters. If your router has removable antennas, try changing their positions: vertically, horizontally, or at a 45-degree angle. In different locations signal polarization from the base station may differ, and by experimentation you can find the position that gives the best SINR.
Band Locking
4G networks operate on different frequencies, and not all of them will work equally well in your location. MTS uses Band 3 (1800 MHz), Band 7 (2600 MHz), Band 20 (800 MHz), and Band 31 (450 MHz). Lower frequencies (Bands 20 and 31) penetrate walls better but have lower throughput.
High frequencies (Band 7) provide maximum speed, but have a short range and poor penetration through obstacles. Often, the router automatically selects the frequency with the strongest signal, but not the fastest. Forced locking (Lock) on a certain range can significantly improve the situation.
To change the band, you need to access the hidden LTE settings menu. Depending on the model, this may be under "Network Settings" -> "Preferred Mode." If the selection is unavailable through standard means, special commands or URLs can be used, such as appending parameters to the router's login address.
Let's consider the main characteristics of the ranges used:
| Band | Frequency (MHz) | Characteristics | Recommendation |
|---|---|---|---|
| Band 20 | 800 | High coverage, low speed | For remote villages where there are no other options |
| Band 3 | 1800 | Balance of speed and coverage | The optimal choice for most users |
| Band 7 | 2600 | High speed, low coverage | Only with direct line of sight to the tower |
| Band 31 | 450 | Very large coverage | For extremely remote objects |
How to enter the Huawei engineering menu?
In the browser's address bar, after the router's IP address (e.g., 192.168.8.1), add the string #modify. Then, go to Settings -> Network Settings -> Network Selection and uncheck "Auto" to select the desired Band.
Using external antennas
If software methods and rearranging furniture fail, the only effective solution is an external antenna. Built-in router antennas have low gain (usually 2-3 dBi). External devices can provide gain of 15-25 dBi or more, which dramatically improves connection quality.
There are two main connection types: via TS9/CRC9 connectors on the router case or via a pigtail adapter if the connectors are hidden internally. Models without external connectors (for example, some versions of the Huawei 832 or ZTE MF833) require careful opening of the case and soldering of pigtails to the contact pads on the board.
Directional antennas of the "Wave Channel" type (MIMO 2x2 or 4x4) are considered the most effective. They require precise alignment with the operator's tower. Omnidirectional antennas ("whips") provide a smaller gain but don't require precise positioning, which is convenient for frequent travelers.
☑️ Buying an antenna
Carrier Aggregation
Modern communication standards allow for the combination of multiple frequency bands to increase channel capacity. This technology is called Carrier Aggregation (CA). If your MTS base station and router support this feature, your speed can increase by 1.5 to 2 times.
Routers of Cat.6 and higher (e.g., Huawei B525, B618, B528, ZTE MF286) support aggregation. In the settings of these devices, you'll often see combinations like B3+B7 or B3+B20. Activation is automatic, but sometimes you may need to force the "LTE Only" mode or a specific band combination.
Keep in mind that aggregation increases the load on the router's processor, and the device may become hotter. Ensure good ventilation, especially if it operates under load 24/7. Overheating can lead to throttling and reduced performance.
⚠️ Please note: Frequency aggregation support depends not only on the router but also on the load on the MTS base station. During peak hours, the operator may disable secondary aggregation components, and speeds will drop to normal levels.
Compatibility and firmware issues
Outdated router software may contain errors that affect the stability of the communication module. Check the firmware version in your device's personal account. MTS periodically releases updates that improve tower switching algorithms and 4G network performance.
However, there's a caveat with locked devices. Routers purchased from carriers on special offers are often locked to other carriers' SIM cards and have limited menu functionality. Reflashing such devices to a universal version (for example, from Huawei to official firmware) can unlock advanced antenna settings and remove these restrictions.
When updating software, it's critical not to interrupt the power supply. Use a stable Ethernet connection for updating, not WiFi. If a failure occurs during the firmware update, the device may become bricked, requiring specialized equipment to repair.
Frequently Asked Questions (FAQ)
Will foil or a beer can help boost the signal?
Using homemade reflectors made of foil or cans produces a very minor and unstable effect. They may slightly alter the radiation pattern of the built-in antenna, but will not provide a real signal boost comparable to an external antenna. In some cases, the metal may even shield the signal, worsening the situation.
Can I use a USB extension cable to move my modem?
Yes, an active USB extender with external power allows you to move the USB modem (wireless modem) closer to a window or mount it on a pole. This is an effective way to improve reception without buying a new router, but the cable length should not exceed 5 meters for stable operation without data loss.
Why is the Internet slower in the evening, even if the signal is full?
This is due to base station channel congestion. In the evening, the number of users on the MTS network increases sharply. The bandwidth is divided among all subscribers, so even with ideal RSRP and SINR, the actual access speed to resources decreases.
Do I need to change my SIM card to 4G?
Old SIM cards (cut from larger formats or issued more than 10 years ago) may not work properly on 4G/LTE networks. If you haven't replaced your card in a while, it's a good idea to contact an MTS store for a free replacement with a SIM card that supports the latest security and communication standards.
