Detailed explanation-1: -Bluetooth uses a spread-spectrum frequency-hopping technology. This means it uses multiple frequencies at the same time to limit interference when using multiple devices. While Bluetooth does not need a direct line of sight, the signals do not carry very far, and the devices need to be within approximately 10 meters.

Detailed explanation-2: -Bluetooth is a technology standard used to enable short-range wireless communication between electronic devices. Since Bluetooth operates on radio frequencies, rather than the infrared spectrum used by traditional remote controls, devices using this technology do not have to maintain a line of sight to communicate.

Detailed explanation-3: -Bluetooth long range (also known as Coded PHY) is a new mode introduced in Bluetooth Version 5.0 to extend the range of Bluetooth devices from 30-100 feet to ranges of 1 kilometer and beyond.

Detailed explanation-4: -Bluetooth (which is a type of RF) is an open wireless technology standard for transmitting data over short distances. It uses radio waves on a particular frequency for data transmission from device to device.
