    Study Notes

    Introduction to Wireless Communication Networks

    • Wireless communication networks transmit voice and data using electromagnetic waves in open space.
    • Frequency and wavelength determine the characteristics of electromagnetic waves.
    • The wireless channel can transmit signals through objects, reflect off objects, scatter signals, and diffract around edges of objects.
    • The demand for mobile communication created the need for integration of wireless networks into existing fixed networks.
    • Wireless networks have higher loss-rates due to interference and restrictive regulations of frequencies.
    • Cellular/WiFi, smart homes/spaces, autonomous cars, smart cities, body-area networks, and the Internet of Things are examples of wireless communication systems.
    • Wireless networks are convenient and less expensive, but limitations and technical difficulties inhibit their full potential.
    • 5-6G, AdHoc Short-Range Wireless Network/Radio Challenges, energy efficiency, scarce/bifurcated spectrum, reliability and coverage, heterogeneous networks, seamless internetwork handoff, and device/system of chip (SoC) challenges are technical issues in wireless communication networks.
    • Current wireless systems include cellular systems, 4G/LTE-Advanced cellular systems, 5G cellular systems, and Wi-Fi systems.
    • Carrier Sense Multiple Access and Collision Detection are mechanisms used in Wi-Fi networks, but they lack good interference mitigation mechanisms, especially in dense AP deployments.
    • Radio frequencies range from 9KHz to 400GHZ, and different agencies license and regulate them.
    • The advantages of using frequency reuse include increased capacity, limited spectrum required, and the same spectrum may be allocated to other networks. The radio communication spectrum is divided into bands based on frequency.
