5. Suggestions from professional organizations
The "White Paper on Mobile Network Quality Optimization" released by the China Academy of Information and Communications Technology states:
1. The root cause of unstable 4G signal isNetwork load does not match user demand, it is recommended to use high-traffic applications during off-peak hours
2. When the mobile phone signal strength is lower than -100dBm, you should consider using an external antenna to enhance it.
3. Regularly check the frequency band support of mobile phone networks. New mobile phones generally support more frequency bands.
6. Comparison of ultimate solutions
| Plan type | cost input | Applicable scenarios | Duration of effect |
|---|---|---|---|
| Upgrade 5G package | Monthly rent increases by 30-50 yuan | Urban coverage area | Effective for a long time |
| Install signal amplifier | Equipment fee of 300-800 yuan | fixed place | 3-5 years |
| Operator complaint optimization | time cost | Regional signaling issues | depending on the circumstances |
| Dual card dual standby backup | Additional SIM card fee | business people | Effective immediately |
Through the above systematic solutions, most 4G signal instability problems can be significantly improved. It is recommended that users try zero-cost basic settings adjustments first, and then consider hardware solutions if there is still no improvement. At the same time, pay attention to the operator's network upgrade trends and enjoy better network services in a timely manner.
