Study Notes
Wireless Network Fundamentals and OSI Model
- Open Systems Interconnection (OSI) model was created by ISO as a standard reference for data communications between computers in the late 1970s.
- The OSI model consists of 7 layers: Application, Presentation, Session, Transport, Network, Data Link, and Physical.
- Wi-Fi operates at Layer 1 and the MAC sublayer at Layer 2.
- Wi-Fi technology is typically used at the access layer networking technology.
- Wireless bridging between buildings is an example of wireless technology being used at the distribution layer in networking.
- Wi-Fi operates in half-duplex mode, allowing both devices to transmit and receive, but only one device can transmit at a time.
- The IEEE 802.11-2012 standard defines mechanisms at the Physical layer and MAC sublayer of the Data-Link layer.
- 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.
- In wireless communications, amplitude, wavelength, frequency, and phase are key concepts used to describe carrier signals.
- 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.
