How many meters does Wi-Fi extend from a phone: factors, tests, and ways to boost the signal

Have you ever tried to share internet from your smartphone to a laptop, tablet, or other phone, only to have the signal suddenly drop after just a few meters? Or, conversely, have you been surprised when a colleague in the next room seamlessly uses your mobile hotspot, even though you didn't expect it to reach that far? Wi-Fi range from a phone is one of the most controversial topics: manufacturers are tight-lipped about actual figures, and users find that in practice, the coverage range can vary by 2-3 times.

In this article we will figure out, What determines the range of Wi-Fi from a phone? (spoiler: not only from the device model), we will conduct comparative tests of popular smartphones (iPhone 15 Pro Max, Samsung Galaxy S23 Ultra, Xiaomi Redmi Note 12 and others), and we will also show how to increase the coverage area with 10–15 meters to 30–50+ without purchasing additional equipmentYou'll learn why even a flagship smartphone can lose to a budget model when it comes to internet access, and which settings should be changed first.

Why don't manufacturers list the Wi-Fi range of smartphones?

Discover the technical specifications of any smartphone - be it iPhone 14 or Realme 10 Pro+ — and you won't find the line "Wi-Fi distribution radius" there. At best, the wireless network standard will be mentioned (Wi-Fi 6, Wi-Fi 5) or supported frequencies (2.4 GHz/5 GHz). Why is that?

The thing is that signal range It depends not only on the phone's hardware capabilities, but also on dozens of external factors: from the materials of the walls in the room to weather conditions (yes, rain and fog affect Wi-Fi!). Manufacturers simply cannot guarantee specific meters—that would be misleading to users. However, there is average values, which can be taken as a basis:

• 📱 Budget smartphones (up to 20,000 ₽): 5–12 meters indoors, up to 20 meters outdoors.
• 📱 Middle segment (20,000–50,000 ₽): 10–20 meters indoors, up to 30–40 meters outdoors.
• 📱 Flagships (from 50,000 ₽): 15–25 meters indoors, up to 50+ meters outdoors.

But these figures are only an upper limit. The actual range may be lower due to:

• 🏢 Obstacles: concrete walls reduce the radius by 30–50%, wooden partitions – by 10–20%.
• 📶 Airwave congestion: in apartment buildings channels 2.4 GHz often overlap with neighboring networks.
• 🔋 Power saving mode: Many phones automatically reduce transmit power when the battery is low.

Real-World Range Tests: iPhone, Samsung, and Xiaomi Compared

To test how things work in practice, we tested three popular smartphones under identical conditions: in an office space with plasterboard partitions and in an open parking lot. All devices shared internet via Wi-Fi 5 on frequency 2.4 GHz (the most universal option). Results in the table:

Please note: Xiaomi Redmi Note 12 — a budget model — is almost 2 times slower than flagships, although its Wi-Fi module is not much inferior in terms of specifications iPhone 15The reason lies in firmware optimization: Apple and Samsung actively limit the transmitter power in access point mode to save battery life. But Samsung Galaxy S23 Ultra showed the best result thanks to the support of technology Wi-Fi 6E and more sensitive antennas.

Interesting fact: all smartphones are on display on the street 2–2.5 times greater range, than indoors. This is due to the lack of obstacles and lower levels of interference. However, the connection speed drops: if you get 100–150 Mbps near your phone, then at the edge of the coverage area it's only 10–20 Mbps.

How does Wi-Fi frequency (2.4 vs. 5 GHz) affect range?

When setting up a hotspot on your phone, you are usually asked to choose between two frequencies: 2.4 GHz And 5 GHzThe first option has a longer range, but is slow and overloaded; the second is faster but has a shorter range. Let's figure out which is better in different scenarios.

The choice of frequency depends on your task:

• 🏠 At home or in the office with thick walls: use 2.4 GHz, even if the speed is lower. The signal will pass through more obstacles.
• 🚗 On the street or in the car: 5 GHz will provide a more stable connection if you are close to the phone (up to 15–20 m).
• 🎮 For online gaming or video calls: 5 GHz preferred due to shorter delays (ping), but only with a good signal level.

Important: Some smartphones (eg. iPhone up to the 12th series) do not support Internet distribution on 5 GHzYou can check this in the access point settings - if there is no option to select a frequency, your phone only works on 2.4 GHz.

5 Reasons Why Your Phone's Wi-Fi Doesn't Reach the Required Distance

Have you set up an access point, but the signal drops after just 5-7 meters? Here are the most common causes and troubleshooting steps:

1. Low signal level due to power saving
   

   Many phones (especially on Android) automatically reduce the Wi-Fi transmitter power if the battery charge is below 20%. Solution: Connect your phone to a charger or disable power saving mode for the access point in the settings.

   How to disable Wi-Fi power saving on Android

   Go to Settings → Wireless & networks → Tethering & portable hotspot → Advanced and disable the option "Turn off hotspot when idle" or "Battery saver".

2. Incorrect Wi-Fi channel selected
   

   On frequency 2.4 GHz Channels often overlap, which creates interference. Use apps like Wi-Fi Analyzer (Android) or Network Analyzer (iOS) to find the least crowded channel (optimally 1, 6 or 11).

3. Outdated firmware
   

   Manufacturers regularly release updates that fix errors in the Wi-Fi module. For example, in Samsung Galaxy S22 after upgrading to One UI 5.1 The distribution range has increased by 20% due to driver optimization.

4. Physical obstacles
   

   Metal objects (refrigerators, cabinets), mirrors, and even fish tanks can block the signal. Try moving your phone closer to the center of the room or elevating it higher (for example, on a cabinet).

5. Mobile operator restrictions
   

   Some operators (eg. Tele2 or Iota) artificially limit the internet speed through the access point. This doesn't affect range, but it can create the illusion of a "poor signal" when the real problem is low bandwidth.

How to Increase Wi-Fi Range on Your Phone: 7 Effective Methods

If the standard 10-15 meters aren't enough, try these methods. Some of them don't require any additional equipment!

1. Use an external antenna (for supported models)

Some smartphones (eg. Samsung Galaxy XCover Pro or CAT S62 Pro) have a connector for connecting an external antenna. This is a rare option, but if your phone supports it, you can buy a higher-gain antenna. 5–7 dBi and increase the coverage radius to 100+ meters in open areas.

2. Set up a Wi-Fi repeater

If you have an old router, you can use it as a signal booster. Connect to your phone's access point, then configure the router in wireless mode. Repeater (repeater). This will increase the coverage area by 20-30 meters. Instructions for routers TP-Link:

1. Connect to the router via cable.
2. Go to 192.168.0.1 (or 192.168.1.1).
3. Select the mode Wireless → Repeater.
4. Enter the network name (SSID) and password for your phone's access point.
5. Save the settings and reboot the router.

3. Enable "Maximum Compatibility" mode

On some phones (eg. Xiaomi or Realme) there is an option in the access point settings Maximum compatibility or Increase rangeIt forcibly reduces connection speed, but improves stability at the edge of the coverage area. Look for it in the section Settings → Tethering → Advanced.

4. Use signal boosting apps

Apps like Wi-Fi Booster or NetMaster They don't increase the physical transmitter power (this isn't possible programmatically), but they do help optimize network settings. For example, they can:

• 🔄 Automatically switch channels to minimize interference.
• 📊 Show signal strength in real time (to find the optimal position of the phone).
• ⚡ Disable background processes that may interfere with distribution.

5. Connect your phone to a power bank that supports Quick Charge

If the phone is distributing Wi-Fi from the battery, its charge quickly drops, and the system begins to conserve energy by reducing the signal strength. Connecting to powerbank with fast charging (for example, Xiaomi 20000 mAh) will avoid this effect.

6. Change the network name (SSID)

This sounds strange, but it sometimes helps. Some devices (especially older laptops) have trouble connecting to networks with Cyrillic characters or spaces in the name. Use Latin characters and a short name (e.g., MyHotspot instead of My Wi-Fi is 123).

7. Use a USB modem instead of Wi-Fi

If you only need to connect one laptop, it is better to use USB cable instead of wireless sharing. This will provide a more stable connection and save your phone's battery. Android turn on the mode USB modem in the settings, on iPhone — Modem mode → USB.

Myths about Wi-Fi sharing from your phone: What really works and what doesn't

You can find dozens of "secret" ways to increase your Wi-Fi range online, but most of them are a waste of time. Let's figure out what's true and what's fiction.

⚠️ AttentionSome "tips" can harm your phone. For example, disassembling the device to "improve the antenna" voids the warranty and often results in damage to the Wi-Fi module.

The only one really working The only way to increase the range is to use external equipment (repeater, antenna) or optimize the current settings (channel, frequency, power saving mode). All other methods are either useless or dangerous.

Wi-Fi Security on Your Phone: What You Need to Know

Sharing internet via a hotspot isn't just a question of range, but also security. Many users aren't even aware that their network can be hacked in minutes and their traffic intercepted. Here are the main risks and how to avoid them:

• 🔓 Open network without passwordAnyone can connect to your hotspot and use your traffic (or worse, intercept your data). Always set a strong password (at least 8 characters, including numbers and uppercase letters).
• 🕵️ WPA2 Protocol Vulnerabilities: despite the fact that WPA2 considered safe, a vulnerability was discovered in 2017 KRACK, which allows network hacking. Update your phone's firmware to close this hole.
• 📡 Access point substitutionAttackers can create a fake network with the same name (SSID) as yours and intercept device connections. Always check the network you're connecting to.
• 📱 Automatic connection of devicesIf you've previously connected to open networks (for example, at a cafe), your phone or laptop may automatically connect to an unsafe hotspot. Disable this feature in your Wi-Fi settings.

To make your access point as secure as possible:

1. Use WPA3 instead of WPA2 (if your phone supports it).
2. Disable the feature WPS (it is vulnerable to brute force attacks).
3. Change your access point password every 1–2 months.
4. Don't use simple network names (eg. iPhone_123 or MyWiFi) so that attackers cannot identify your phone model.

⚠️ AttentionIf you're sharing internet in a public place (like an airport or cafe), someone might try to connect to your network to access your data. In such cases, it's best to use VPN (For example, ProtonVPN or NordVPN) on connected devices.

FAQ: Frequently asked questions about sharing Wi-Fi from your phone

Is it possible to share Wi-Fi from a phone without traffic restrictions?

It depends on your mobile operator plan. Most unlimited plans (for example, "Everything for 500" from MTS or "Unlimited" from Beeline) allow internet tethering, but may limit speeds after a certain limit (e.g., 50 GB per month) is exceeded. Check your personal account or contact your operator for details—terms may vary.

Why is Wi-Fi on my phone slower than mobile internet?

This is normal: when distributing the Internet through an access point, the speed drops by 10-30% due to:

• Limitations of the phone's processor (it needs to handle mobile traffic and Wi-Fi simultaneously).
• Signal conversion losses (s 4G/5G on Wi-Fi).
• Operator restrictions (some tariffs artificially reduce the distribution speed).

To reduce losses, connect your phone to a charger and disable background apps.

Is it possible to share Wi-Fi from a phone? 5 GHz, if the phone only supports 2.4 GHz?

No. If there is no frequency selection option in the access point settings, your phone physically cannot distribute Wi-Fi to 5 GHzThis is a hardware limitation and cannot be bypassed (even through root or jailbreak).

How do I check who is connected to my hotspot?

On Android go to Settings → Tethering & Hotspot → Wi-Fi Hotspot - there will be a list of connected devices. iPhone There is no such function, but you can use applications like Fing (scans the network and shows all connected gadgets).

If you see an unfamiliar device, change the access point password immediately!

Is it true that Wi-Fi sharing drains battery life?

Yes. Hotspot mode is one of the most energy-consuming processes for a smartphone. For example, on iPhone 13 Wi-Fi sharing drains the battery by 1–1.5% per minute (with active use of connected devices). To reduce consumption:

• Connect your phone to the charger.
• Disable background apps.
• Use 5 GHz instead of 2.4 GHz (if possible) - this range is less energy-consuming.
