Bluetooth is also a good method for transmitting audio to speakers or headphones, making it versatile and compatible with various devices.
Describe the differences in power level and range between Bluetooth technology and 802.11 wireless LAN technologies.
Bluetooth technology operates at a lower power level, limiting it to low-speed, short-range communications. On the other hand, 802.11 devices transmit at a much higher power level, giving them a greater range and improved throughput.
Explain the frequency ranges commonly used by wireless technologies in home networks and the specific technology associated with the 2.4 GHz band.
Wireless technologies in home networks commonly use the unlicensed 2.4 GHz and 5 GHz frequency ranges. Bluetooth technology makes use of the 2.4 GHz band for its operations.
Discuss the primary usage of Bluetooth technology in connecting computer peripherals and transmitting audio.
Bluetooth technology is commonly used to connect computer peripherals such as wireless mice, keyboards, and printers, due to its one-to-many communication capabilities. Additionally, it is a good method for transmitting audio to speakers or headphones, making it versatile for multimedia applications.
Explain the positioning of wireless LAN technologies in the electromagnetic spectrum and their advantage over Bluetooth technology.
Wireless LAN technologies, conforming to various IEEE 802.11 standards, exist on the electromagnetic spectrum alongside Bluetooth technology. Unlike Bluetooth, 802.11 devices transmit at a much higher power level, giving them a greater range and improved throughput, making them suitable for broader and faster network communications.
