Wireless communications is a rapidly growing segment of the communications industry, with the potential to provide high-speed, high-quality information exchange between portable devices located anywhere in the world. Wireless applications include portable media-enabled devices (phones, tablets, and computers), automated tracking systems, mobile VTC, unmanned vehicles and sensors, and autonomous sensor networks. However, supporting these applications using wireless techniques poses a significant technical challenge. This module will cover advanced topics in wireless communications for voice, data, and multimedia.

The module includes an overview of current wireless systems and standards, characteristics of the wireless channel (including path loss for different environments, random log-normal shadowing due to signal attenuation and the flat and frequency-selective properties of multipath fading), the fundamental capacity limits of wireless channels and the characteristics of the capacity-achieving transmission strategies, practical digital modulation techniques and their performance under wireless channel impairments (including flat and frequency selective fading), techniques to improve the speed and performance of wireless links, the design and performance of adaptive modulation and diversity techniques to compensate for flat-fading, adaptive equalization, multicarrier modulation, and spread spectrum.

Additional topics include frequency reuse, cellular structures, traffic channel calculation, handover, data over cellular, multipath fading, diversity reception, MIMO, modulation techniques, digital cellular systems (3G and 4G), spectral efficiency considerations, and spectral management and regulations. The module will also introduce wireless systems design, including multiple and random access techniques, WLANs, cellular system design, and ad-hoc network design. Applications for these systems, including the evolution of cell phones and PDAs, mobile VTC, and sensor networks, will also be discussed. The final section of the module will include satellite-specific topics: Kepler's laws, error control, transmission losses, link power budget, antenna issues, satellite access, and integration of satellite links into broader networks.

Module Objectives:

The objective of this course is to gain a solid knowledge of technical issues and solutions for wireless communications systems such as GSM, UMTS, and CDMA2000, as well as fundamental concepts and technologies used to build these communication systems.

Students should be able to accomplish the following after attending this module:

  • Explain the function and service provided by each component within a wireless telecommunications systems model.
  • Describe basic wireless mechanisms and multiplexing.
  • Understand the effect of propagation losses and be able to construct a path loss model.
  • Identify the effect of antenna characteristics: antenna gain, near and far field effects, directionality, and use of antenna arrays.
  • Recognize wireless network vulnerabilities and be able to apply appropriate security, spread spectrum, or other techniques to protect communications from interception, cyber attacks, jamming, or other interference.
  • Understand the constraints involved in satellite communications and the techniques required to integrated satellite links with broader communications networks.
