The University of Hawaii developed the first wireless network, ALOHAnet, in 1970.

The first wireless network, ALOHAnet, was used to wirelessly communicate data between the Hawaiian Islands.

The Wi-Fi Alliance is responsible for managing RF spectrum worldwide to ensure interference-free communications.

ALOHAnet technology is considered a precursor to Carrier Sense Multiple Access with Collision Detection (CSMA/CD) in Ethernet.

The FCC regulates only licensed spectrum communications, overseeing areas such as frequency and power.

The IEEE, a global professional society, does not develop standards for communication technologies, including the 802.11 WLAN standard.

The 802.11-2020 standard, defining WLAN frame format and MAC sublayer operations, is not the most recent version.

The ISO, a global organization, develops standards in partnership with sectors to meet business, government, and societal needs, including the ISO 7-layer model.

The IETF, an international community, creates and maintains standards (RFCs) for network-based technologies.

Wi-Fi operates at Layer 1 and the MAC sublayer at Layer 2.

Wireless bridging between buildings is an example of wireless technology being used at the distribution layer in networking.

In wireless networking, the Core layer is the high-speed backbone, the Distribution layer routes traffic between VLANs and subnets, and the Access layer delivers traffic to end users.

Keying methods such as Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK) are used to represent data in wireless networks.

Amplitude-Shift Keying (ASK) uses the amplitude of a signal to represent binary data, while Frequency-Shift Keying (FSK) varies the frequency of the wave to represent binary data.

Phase-Shift Keying (PSK) varies the phase of the wave to represent binary data, and Multiple Phase-Shift Keying (M-PSK) can encode multiple bits per symbol using four phases.

Wi-Fi technology is typically used at the access layer networking technology.

The IEEE 802.11-2012 standard defines mechanisms at the Physical layer and MAC sublayer of the Data-Link layer.
