The enormous popularity of Wi-Fi has led to increasing demands for enhancing the data rate and other features in these wireless networks. Wi-Fi networks have rivaled cellular networks in terms of growth and popularity. There is much debate in the industry whether Wi-Fi competes with or complements 3G/4G networks. Wi-Fi technology is based on evolving 802.11 set of standards. This course covers the landscape of Wi-Fi standards, details of air Interface, network operations and deployment strategies. The course also deals with all major aspects of Wi-Fi including the possible interaction with cellular networks and future trends from a technology and application perspective.
Learning Objectives
After completing this course, the student will be able to: • Understand the link between Wi-Fi and IEEE 802.11 standards • List the RF bands relevant for Wi-Fi • Explain the different deployment scenarios for Wi-Fi • Describe the underlying technologies of Wi-Fi such as OFDM and MIMO • Understand the basics of the MAC in Wi-Fi and also be able to explain features such as frame aggregation, block ACK, TXOP, RIFS and the reverse direction protocol • Explain the security features and protection mechanisms relevant for Wi-Fi deployments • Understand how Wi-Fi networks are gearing up for working with cellular networks • Explain the future technology and application trends in Wi-Fi
