Many users are confused LTE s 3G or 5G, We don't understand the differences in speed, coverage and power consumption. In this article, we'll go into detail about how it works. 4G-Xiaomi Redmi Note 7, what frequency ranges the model supports, how to check the current connection and fix the typical problems - from lack of network to slow Internet" LTE How to fix it without going to the service center.

What is LTE and how it differs from 3G/5G in Xiaomi Redmi Note 7

LTE (Long-Term Evolution) is a fourth-generation (4G) wireless standard that delivers data rates of up to 150 Mbps in theory and 30-80 Mbps in practice. The Xiaomi Redmi Note 7 uses a modification of the LTE Cat. 12 that supports frequency aggregation (merging multiple bands to increase speed).

For comparison:

• 📡 3G (UMTS/HSPA+): maximum 42 Mbps, high latency (ping), quickly drains the battery when used.
• 🚀 LTE (4G): Up to 150 Mbps, low ping (ideal for online gaming and video calling), more energy efficient.
• ⚡ 5G: theoretically up to 1-10 Gbps, but Redmi Note 7 does not support it (this is the prerogative of the flagships Xiaomi 2020).+ year-end).

It is important to understand that the real speed depends not only on the smartphone, but also on the operator, the load of the base station, weather conditions and even the thickness of the walls in the room. For example, in the center of Moscow, the Redmi Note 7 can show 70-90 Mbps on LTE, and in rural areas – barely reach 10-15 Mbps.

The Redmi Note 7 uses the Qualcomm Snapdragon 660 chipset, which supports:

• 📶 LTE FDD: ranges 1, 3, 5, 7, 8 (most common in Russia and Europe).
• 🌍 LTE TDD: ranges 38, 40, 41 (used in Asia, for example, in China).
• 🔄 Carrier Aggregation: Combining multiple bands to increase speed.

What LTE ranges supports Xiaomi Redmi Note 7: the full list

The ranges supported will determine whether your Redmi Note 7 will catch 4G in a particular region. In Russia, the main operators (MTS, Beeline, MegaFon, Tele2) use the B1 bands (2100 MHz), B3 (1800 MHz), B7 (2600 MHz) and B20 (800 MHz), the latter especially important for coverage in rural areas and inside buildings.

Here is the full list of supported Xiaomi Redmi Note 7 LTE bands:

If your smartphone is not catching 4G in some region, check if the local operator supports at least one of the listed ranges. For example, in Crimea and some regions of the Far East, non-standard frequencies that are not included in the Redmi Note 7 list can be used.

2. Network settings: Go to Settings → SIM-maps and mobile networks → Name of the access point (APN). Here you should select your operator profile (for example, Internet.mts.ru for MTS).
3. Speed test: Install Ookla's Speedtest app and run the check. If you're speeding above 20 Mbps, you're exactly connected to LTE.

If there is a 4G icon but the speed is low (less than 10 Mbps), the problem may be:

• 📶 Weak signal (check the number of "sticks" of the network indicator).
• 🔄 Overloaded tower (especially during rush hour).
• 📱 Incorrect settings APN (more about this in the next section).
