Introduction to Wireless Communication and Elements of Wireless Communication Sy10:59
Explore the fundamentals of wireless communication, from historical concepts to the three transmission modes—simplex, half duplex, and full duplex—and the key elements: transmitter, channel, receiver, and noise.
Session 2 Frequency for Radio Communication9:38
Explore how radio communication uses the electromagnetic spectrum, where frequency and wavelength are inversely related, and how ITU allocations prevent interference across RF bands from low to extremely high frequencies.
Session 3 Signal Noise and Type of Noise7:29
Explore signals, noise, and noise types, including amplitude, frequency, and phase; distinguish external and internal noise and modulation's role in wireless transmission.
Session 4 Introduction to Modulation and Demodulation12:28
Explore how modulation and demodulation enable long-distance wireless transmission by carrying a baseband message on a carrier, using amplitude, frequency, and phase modulation.
Session 5 Multiple Access Schemes Frequency Division Multiple Access4:19
Explore how multiple access techniques share spectrum, focusing on frequency division and guard bands. Learn how bandwidth, narrowband and wideband systems shape wired and wireless applications.
Session 6 Frequency and Phase Modulation4:35
Learn how frequency modulation varies the carrier frequency with the modulating signal’s amplitude and how phase modulation shifts the carrier phase, with key equations and modulation index.
Session 7 Code Division Multiplexing4:27
Learn the basics of code division multiplexing in spread spectrum systems, where unique orthogonal codes separate narrowband channels, yielding low interference and secure communication through code multiplication and detection.
Session 8 Time Division Multiplexing6:48
Time division multiplexing allocates time slots for multiple devices within a channel, using frames controlled by a multiplexer; it has synchronous and asynchronous forms with slot utilization and capacity trade-offs.
Session 9 Cell Sectoring and Cell Splitting4:09
Explore self sectoring and cell splitting to subdivide congested cells, boosting capacity without new spectrum. Replace omnidirectional antennas with directional ones to reduce co-channel interference and increase frequency reuse.
Session 10 Medium Access Control22:08
Explore medium access control concepts, from hidden and exposed terminal problems to near and far effects, and compare aloha, tdma, fdma, sdma, and cdma approaches for efficient wireless access.
Session 11 GSM12:51
Explore gsm, the global system for mobile communication, tdma-based, and its core components: base transceiver station, base station controller, mobile switching center, hlr, vlr, stp, smsc.
