When you find yourself in areas with poor mobile network reception, your phone automatically increases its output power to the maximum level. It does this to "reach" the operator's base station. The power emitted by the phone can reach up to 2 W (2000 mW) in such conditions.
For comparison, here are examples of the power of devices you use daily:
- Cordless landline phones: 10 mW - 250 mW
- Laptop Wi-Fi modules, access points: 100 mW - 200 mW
- Bluetooth headsets: 1 mW - 100 mW
Anyone who frequently experiences poor GSM signal reception will have noticed that their phone's battery drains quickly and the device heats up rapidly during calls. This is evidence that your phone is operating at maximum power, attempting to establish a connection with the operator's base station.
What Does a GSM Repeater Do in Such Cases?
A repeater receives the signal from the operator's base station, amplifies the GSM signal, and then transmits a strong signal into the room with poor reception. This ensures a high-quality and stable connection indoors. Furthermore, standard household GSM amplifiers typically have a power output ranging from 5 mW to 100 mW. Now, once again, consider the power levels of the devices you use daily (see above).
In Summary
Through these simple calculations, it can be concluded that by using a mobile signal booster, you can not only achieve a high-quality connection but also reduce the radiation exposure from your mobile phones.
