With the advancement of technology, smart watches have become an important device in the daily life of many people. It not only displays time, but also has multiple functions such as phone calls, messages, and health monitoring. Smart watches are closely connected to mobile phones and rely on wireless signals for communication.cell phone jammers can shield smart watch models. So, can mobile phone shielding bags also shield smart watch signals?
Working principle of phone shielding bags
phone shielding bags are based on the principle of Faraday cages and are made of conductive materials (such as metal fibers, aluminum foil, etc.) to form a shielding layer that effectively blocks the transmission of electromagnetic signals. When the mobile phone is placed in the shielding bag, external wireless signals (such as cellular networks, Wi-Fi, Bluetooth, etc.) cannot penetrate the shielding layer, thereby cutting off the communication between the mobile phone and the outside world.
Types of wireless signals for smart watches
- Smart watches usually use a variety of wireless signals for communication, including:
- Bluetooth signal: used to pair with mobile phones and transmit data, such as notifications, calls, music control, etc.
- Wi-Fi signal: used to directly access the Internet without a mobile phone connection
- Cellular signals: Some smartwatches are equipped with independent SIM cards, which can directly make calls, send text messages and use mobile data like mobile phones.
- GPS signals: Used for positioning and navigation.
What signals can phone shielding bags block?
phone shielding bags can effectively block the following wireless signals:
Cellular signals (2G, 3G, 4G, 5G): After these signals are blocked by the shielding bag, the mobile phone cannot communicate with the mobile network base station.
Wi-Fi signals (2.4 GHz and 5 GHz): The shielding bag can block the entry and exit of Wi-Fi signals, cutting off the device's connection to the wireless network.
Bluetooth signals (2.4 GHz): The shielding bag can also block Bluetooth signals to prevent wireless data transmission between devices.
GPS signals (1.2 GHz and 1.5 GHz): The shielding bag can block GPS signals, making it impossible for the device to be located.
Can phone shielding bags block the signals of smart watches?
Since smart watches use similar types of wireless signals as mobile phones, phone shielding bags can theoretically block the signals of smart watches. Here is a detailed analysis:
Bluetooth signal: When the smartwatch is placed in the phone shielding bag, the Bluetooth signal cannot penetrate the shielding layer, and the watch will not be able to pair with the mobile phone and transmit data.
Wi-Fi signal: If the smartwatch has Wi-Fi function, the shielding bag can block the Wi-Fi signal, so that the watch cannot connect to the wireless network.
Cellular signal: For smartwatches with independent cellular network function, the shielding bag can block its cellular signal, preventing the watch from making calls and using mobile data.
GPS signal: The shielding bag can block GPS signals, making it impossible for the smartwatch to locate and navigate.
The actual effect of using a phone shielding bag to shield the smartwatch signal
Although the phone shielding bag can theoretically block the signal of the smartwatch, the actual effect may be affected by the following factors:
The quality of the shielding bag: High-quality shielding bags usually use multiple layers of conductive materials for better shielding effect. Low-quality shielding bags may not completely block all signals.
Signal strength: If the wireless signal strength received by the smartwatch is very high, a small amount of signal may penetrate the shielding bag, affecting the shielding effect.
Bag closure: The shielding bag needs to be completely closed to effectively shield the signal. If the bag is not completely sealed, the signal may enter through the opening part.
phone shielding bags can not only effectively shield the wireless signals of mobile phones, but also the signals of smart watches. By blocking wireless signals such as Bluetooth, Wi-Fi, cellular and GPS, shielding bags can effectively prevent smart watches from communicating with the outside world, protecting personal privacy and information security. However, the actual effect may be affected by the quality, signal strength and closure of the shielding bag. When selecting and using a shielding bag, you should pay attention to quality and closure to ensure that it can provide the best shielding effect.
