The correct answer is option 1. Bluetooth technology allows for wireless communication between various devices and equipment.
Option 2 is incorrect because Bluetooth is not limited to just mobile phones. It can be used to connect and communicate between a wide range of devices, such as laptops, tablets, headphones, speakers, and smartwatches.
Option 3 is also incorrect because Bluetooth is not specifically designed for landline to mobile phone communication. It can be used for communication between any two Bluetooth-enabled devices, regardless of their connection type (landline or mobile).
Option 4 is incorrect as well because Bluetooth technology is not used for satellite television communication. Bluetooth is a short-range wireless technology that operates within a specific distance, typically up to 30 feet (or 10 meters), and is commonly used for connecting devices within close proximity.
In summary, Bluetooth technology enables wireless communication between different types of devices, making it a versatile and widely-used technology for connecting and exchanging data between devices such as smartphones, laptops, audio devices, and more.
