How to check the digital signal value of mobile phone
In the era of mobile Internet, the strength of mobile phone signals directly affects call quality and Internet experience. Many users are curious about the "numeric value" of the mobile phone signal bar. This article will explain in detail how to check and understand the signal strength of the mobile phone, and attach the hot topic data of the entire network in the past 10 days for reference.
1. The meaning of mobile phone signal strength
Cell phone signal strength is usually measured in dBm (decibel milliwatts), ranging from -50dBm (very strong) to -120dBm (very weak). The following are the states corresponding to common signal values:
| Signal value (dBm) | signal strength | User experience |
|---|---|---|
| -50 to -75 | Extremely strong | 4G/5G full speed, clear calls |
| -76 to -90 | good | Normal Internet access, with occasional delays |
| -91 to -100 | Average | Web pages load slowly |
| -101 to -120 | weak | Frequent disconnections |
2. How to check the signal value
1.Android phone: Enter [Settings]-[About Phone]-[Status Information]-[SIM Card Status]
2.iPhone: Enter *3001#12345#* on the dial keyboard and click [Serving Cell Measurements]
3.Third-party applications: Such as Network Signal Info, Cellular-Z, etc.
3. Factors affecting signal strength
| factors | degree of influence | solution |
|---|---|---|
| Base station distance | high | near a window or high place |
| architectural occlusion | high | Use a signal amplifier |
| weather disturbance | in | Restart phone |
| SIM card aging | low | Replace with new SIM card |
4. Reference for hot topics across the Internet (last 10 days)
Combined with current hot topics, the following are discussion trends related to mobile phone signals:
| topic | Platform popularity | relevance |
|---|---|---|
| 5G signal coverage map | Weibo hot search No. 8 | directly related |
| iPhone 15 signal gate | Zhihu hot list | Hardware reference |
| Elevator signal enhancement solution | Douyin playback volume 20 million+ | Scenario application |
| Satellite calling mobile phone comparison | TOP3 of Bilibili Science and Technology Zone | Technology extension |
5. Signal optimization suggestions
1.Prioritize carrier: The signals of each operator in different regions vary greatly. You can check the coverage map through the official APP.
2.Update system version: Mobile phone manufacturers will continue to optimize baseband drivers
3.Avoid metal protective cases: Metal materials will block signals
4.Emergency handling:Reset network connection 10 seconds after enabling airplane mode
Conclusion
Understanding mobile phone signal values can help users proactively improve the communication environment. When the signal value is below -100dBm, it is recommended to take the optimization measures mentioned in the article. As 5G network construction advances, future indoor deep coverage technologies (such as millimeter waves) will further improve signal stability.
