When choosing between mobile internet and Wi-Fi, users often face the question: which option will provide the highest speed? The answer isn't as obvious as it might seem. Speed depends on dozens of factors, including connection technologies (4G vs 5G vs Wi-Fi 6) to network congestion and even weather conditions. In this article, we'll examine:
- How real speed mobile Internet and Wi-Fi differs from that declared by providers,
- which technical limitations affect the performance of each connection type,
- what is the correct way? test speedto obtain objective results,
— in which scenarios is it better to give preference mobile network, and where - Wi-Fi.
Spoiler: there's no one-size-fits-all answer. But after reading this, you'll be able to determine exactly what kind of internet is best for your needs—whether it's online gaming, streaming, 4K or working with cloud services.
1. Theoretical maximums: what do providers promise?
On paper, the difference between mobile internet and Wi-Fi seems colossal. Modern standards promise:
- 📶 5G: to
10 Gbps(under ideal conditions), in reality -100–500 Mbps. - 📶 4G (LTE-Advanced): to
1 Gbps, really -30–100 Mbps. - 📡 Wi-Fi 6 (802.11ax): to
9.6 Gbps, really -500 Mbps – 1 Gbps. - 📡 Wi-Fi 5 (802.11ac): to
3.5 Gbps, really -200–400 Mbps.
However, these figures are a marketing ploy. The actual speed depends on:
- 🔄 Base station load (for mobile Internet) or Wi-Fi channel.
- 📦 Tariff plan (many operators limit speed after high-speed traffic is exhausted).
- 📡 Distance to router/tower and obstacles (walls, furniture, weather).
- 🖥️ Hardware limitations devices (for example, a smartphone with Wi-Fi 4 will not reveal its potential Wi-Fi 6).
⚠️ Attention: Providers often quote speeds as "up to"—the maximum possible value under ideal conditions. Actual speeds can be 5-10 times lower.
2. Real-World Speed Tests: Mobile Internet vs. Wi-Fi
To compare speeds objectively, we conducted tests in the Moscow region (2026) on the following devices:
- 📱 Samsung Galaxy S24 Ultra (5G, Snapdragon 8 Gen 3).
- 💻 MacBook Pro M3 (Wi-Fi 6E, connected to ASUS RT-AX88U Pro).
- 📺 Sony Bravia X90L (Wi-Fi 6, connected to the same router).
Results (average values for 10 tests at different times of the day, service Speedtest by Ookla):
| Connection type | Download (Mbps) | Upload (Mbps) | Ping (ms) | Stability |
|---|---|---|---|---|
| 5G (MTS) | 280 | 45 | 22 | Average (variation ±30%) |
| 4G (Tele2) | 75 | 18 | 38 | Low (fluctuations ±50%) |
| Wi-Fi 6 (2.4 GHz) | 120 | 95 | 8 | High (fluctuations ±10%) |
| Wi-Fi 6 (5 GHz) | 450 | 180 | 5 | Very high (variation ±5%) |
Key takeaway: Wi-Fi 6 at 5 GHz outperforms 5G in download speed and stability, but loses out in mobility. However, in conditions with a weak Wi-Fi signal (for example, in a remote room), 4G/5G may be faster.
3. What affects mobile internet speed?
Mobile network speed depends on factors often beyond the user's control. Let's look at the main ones:
3.1. Network technology (4G vs 5G)
5G theoretically faster, but:
- 📡 5G coverage is still fragmented (in 2026, it will only be fully operational in large cities).
- 📵 Frequencies mmWave (24+ GHz) give speed up to
1 Gbps, but they penetrate walls worse than Sub-6 GHz. - 🔄 Many operators use DSS (Dynamic Spectrum Sharing), which divides frequencies between 4G and 5G, which reduces speed.
3.2. Base station load
During rush hour (6:00 PM–11:00 PM), speed can drop by 2–3 times. For example, in tests 4G from Beeline showed it during the day 80 Mbps, and in the evening - 25 Mbps.
3.3. Tariff plan and restrictions
Operators often enter:
- 📉 FUP (Fair Usage Policy) - after the high-speed traffic is exhausted, the speed drops to
1–5 Mbps. - 🔒 Traffic prioritization (for example, torrents or videos may be artificially limited).
- 🕒 Night unlimited — the speed is higher from 00:00 to 7:00, but lower during the day.
⚠️ Attention: Some operators (eg. Yota) use "virtual unlimited plans"—after exceeding the limit, the speed doesn't reset, but it does drop significantly. Check the terms in your personal account.
4. What affects Wi-Fi speed?
Unlike mobile internet, Wi-Fi speed can be optimized independently. Key factors:
4.1 Wi-Fi standard and frequency
Comparison of standards:
- 🐢 Wi-Fi 4 (802.11n): to
600 Mbps, but in practice -50–100 Mbps. - 🏃 Wi-Fi 5 (802.11ac): to
3.5 Gbps, really -200–400 Mbps. - 🚀 Wi-Fi 6/6E (802.11ax): to
9.6 Gbps, really -500 Mbps – 1.5 Gbps.
Frequencies:
- 📡 2.4 GHz: passes through walls better, but is subject to interference (microwaves, neighbors).
- 📡 5 GHz: higher speed, but shorter range.
- 📡 6 GHz (Wi-Fi 6E): minimal interference, but requires support from devices.
4.2 Channels and interference
If there are many networks nearby on the same channel, the speed drops. For example, in an apartment building on a channel 6 (2.4 GHz) there may be up to 20 networks - this leads to collisions and a reduction in speed by 30–50%.
Solution:
- 🔍 Use apps like Wi-Fi Analyzer to search for a free channel.
- 🔄 Set your router to automatically select a channel or select it manually (for example,
149at 5 GHz).
4.3. Router location
Optimal placement:
- 📍 In the center of the apartment/house.
- 🚫 Keep away from metal objects, mirrors and thick walls.
- ⬆️ At a height of 1–1.5 meters from the floor.

5. When is mobile internet faster than Wi-Fi?
There are scenarios where 4G/5G is preferable:
- 🏠 Weak Wi-Fi signal: If you are in a remote room or behind several walls, your Wi-Fi speed may drop to
10–20 Mbps, and 4G will provide stable50–70 Mbps. - 🚆 Movement: On trains, cars or public transport, Wi-Fi often disconnects, while the mobile network maintains a connection (albeit with speed fluctuations).
- 🏢 Overcrowded public Wi-Fi: In cafes, airports, or hotels, speed may be artificially limited, but mobile internet will remain faster.
- 🔌 No power outletIf you urgently need to download a file and your router isn't turned on, 4G/5G will be your salvation.
Example: in tests on Moscow Central Circle (MCC) speed Wi-Fi in the carriage fluctuated between 5 to 40 Mbps, whereas 5G (MegaFon) consistently produced 120–150 Mbps.
⚠️ Attention: Mobile internet is often slower than Wi-Fi in the metro due to tunnels shielding it. Check your carrier's coverage before traveling.
6. When is Wi-Fi faster than mobile internet?
Wi-Fi clearly wins in the following cases:
- 🎮 Online games: low ping (
5–10 msagainst20–50 ms(4G/5G) is critical for shooters or MMORPGs. - 📺 4K/8K Streaming: for stable playback you need
50+ Mbps, which is easier to provide over Wi-Fi 6. - 💼 Working with cloud services: downloading large files (for example, in Google Drive or Figma) faster via cable or Wi-Fi.
- 🖥️ Local area network: transfer files between devices via Wi-Fi (
100–500 Mbps) faster than via mobile Internet.
Test: When downloading a game Call of Duty: Warzone (120 GB) via Wi-Fi 6 the process took 35 minutes, whereas in 5G — 1 hour 10 minutes (due to speed fluctuations).
7. How to test speed correctly?
To ensure a fair comparison, please follow these rules:
7.1 Testing Tools
Use:
- 📊 Speedtest by Ookla (popular, but sometimes underestimates results).
- 📈 Fast.com (from Netflix, shows streaming speed).
- 🔍 nPerf (tests not only speed, but also stability).
7.2 Testing conditions
For objectivity:
- 🕒 Conduct tests at different times of the day (morning/afternoon/evening).
- 📍 Stand next to the router (for Wi-Fi) or in an open area (for mobile Internet).
- 🔄 Disable background downloads (torrents, updates).
- 📱 Reboot your device before testing.
7.3. Analysis of results
Pay attention not only to the download speed, but also to:
- 📤 Upload speed (important for streams, video calls).
- 🕒 Ping (critical for gaming and video conferencing).
- 📉 Stability (speed fluctuations over time).
Why does Speedtest show different results for different providers?
The service selects the closest server for testing. If your carrier has an agreement with one data center and your Wi-Fi provider has an agreement with another, the results will differ even if the actual speed is the same.
8. Future: What will be faster in 5 years?
Technology never stands still. In the coming years, we can expect:
- 🚀 6G: promises speed up to
1 Tbit/s(tests will begin after 2030). - 📡 Wi-Fi 7 (802.11be): to
46 Gbps, is already available in flagship routers (for example, TP-Link Archer BE800). - 🌍 Satellite Internet (Starlink, OneWeb): speed
100–300 Mbpseven in remote regions. - 📶 5G Advanced: 5G evolution with improved stability and lower ping.
However Even with the advent of 6G, Wi-Fi is unlikely to lose its relevance—it remains the most stable and affordable solution for home and office use.
FAQ: Frequently Asked Questions
❓ Why is Wi-Fi on my phone slower than 4G?
Possible reasons:
- Your smartphone only supports Wi-Fi 4/5, and the router is Wi-Fi 6 (backward compatibility limits speed).
- The router is configured for a congested channel (check in Wi-Fi Analyzer).
- Feature enabled
Smart Connect(auto switching between 2.4 and 5 GHz), which selects a less crowded but slow channel.
Solution: Manually select the range 5 GHz in the Wi-Fi settings on your phone.
❓ Can I use 5G instead of my home internet?
Technically yes, but there are some nuances:
- 💰 Cost: unlimited 5G plans (e.g. MTS "Everything for our own") cost in
1500–2500 ₽/month, which is more expensive than many wired tariffs. - 📡 Stability: during rush hour, speed can drop to
30–50 Mbps. - 🔌 Equipment: required 5G router (For example, Huawei 5G CPE Pro 2) or a smartphone with the function
USB/Wi-Fi tethering.
Conclusion: 5G is suitable as a backup channel or for temporary use (for example, at a summer house). For permanent use, wired internet and Wi-Fi 6 are better.
❓ Which ping is better for gaming: Wi-Fi or 4G?
Wi-Fi (especially via cable) always gives a lower ping:
- 🎮 Wi-Fi 6 (5 GHz):
5–15 ms. - 📶 4G:
30–60 ms. - 📶 5G:
20–40 ms(better than 4G, but worse than Wi-Fi).
Exception: If you are playing on a smartphone away from the router, 5G may cause ping issues. 25–35 ms, which is acceptable for most games.
❓ Why does Wi-Fi speed drop at night?
Possible reasons:
- 🕒 System updatesWindows, macOS, or your router may be downloading updates in the background.
- 📡 Interference: neighbors are also active at night, and their devices create a load on the channel.
- 🔄 Tariff restrictions: Some providers throttle speed at night (check your contract).
Solution: Set up QoS on your router to prioritize your traffic.
❓ Is it possible to combine Wi-Fi and mobile internet to increase speed?
Yes, there are several ways:
- 🔗 Channel Bonding: special routers (for example, Peplink Balance) combine several channels (4G + Wi-Fi + wired Internet).
- 📱 Speedify: A PC/smartphone app that summarizes your Wi-Fi and mobile network speed.
- 🖥️ Windows 11: built-in function
Advanced Network Settingsallows you to use both connections simultaneously.
Example: when merging Wi-Fi (200 Mbps) And 5G (150 Mbps) the actual speed was 300 Mbps (not the amount, but there is an increase).
