Bluetooth is a standard for very low powered and short-range radio connections. As a radio technology, it does not require a line-of-sight connection as an infrared connection does. Bluetooth is used to link Personal Digital Assistant (PDA), mobile phones, and laptops, and provides them with Internet access via hot spots. It uses the 2.4 Ghz spectrums with a data transfer rate of about 1 Mbps. Bluetooth networks are not permanent as compared to other networks where a central communication point is needed such as a hub or a router. A Bluetooth network can be formed when two Bluetooth devices are within a range of ten meters, enabling them to communicate directly with each other. This dynamically created network is known as a piconet. A Bluetooth-enabled device can support up to seven other Bluetooth devices in a master-slave relationship; the first Bluetooth device is the master, and all the other devices are slaves that communicate with the master in one piconet. The maximum transmission range of Bluetooth is around 10 meters. Answer option D is incorrect. The infrared devices require a line-of-sight connection between devices.
Answer option B is incorrect. The maximum transmission range of Bluetooth is around 10 meters.
