Final answer:
Protocol IEEE 802.11 encompasses all aspects of wireless local area networking, including specifications for MACs, physical layers, and frequency bands for WLAN communication, as well as forming the basis for WiFi compatibility among wireless products.
Step-by-step explanation:
Protocol IEEE 802.11 refers to a set of standards for implementing Wireless Local Area Network (WLAN) computer communication in various frequency bands, including the 900 MHz, 2.4 GHz, 3.6 GHz, 5 GHz, and 60 GHz frequency bands. It defines media access controls (MACs) and physical layer (PHY) specifications to enable wireless networking of devices. Additionally, the standard and its amendments provide a basis for wireless network products that use the WiFi brand, ensuring compatibility and interoperability among different manufacturers' devices. The correct answer to the student's question is, thus, '5) all of the above' as the IEEE 802.11 encompasses MAC and PHY specifications, specifies the frequencies for WLAN communications, and forms the basis for WiFi-enabled wireless networking products.
