Learn modern wireless communication system

Learn how cellular systems solve spectral congestion by using small, low-power base stations and frequency reuse across hexagonal cells to boost capacity while minimizing interference.

Analyze channel assignment strategies in cellular systems using frequency reuse to boost capacity and reduce interference. Compare fixed and dynamic channel assignment and their effects on blocking and control.

Explain handoff in cellular networks, including when to switch base stations, threshold levels, dwell time, and the distinction between hard and soft handoff and intra-cell and inter-cell handovers.

Explore the basic OSI model, its seven layers, and how repeaters, bridges, routers, and gateways interconnect networks with protocol conversion.

Explore switching in network models, comparing circuit, packet, and message switching, and analyze connection establishment, data transfer, delays, and efficiency with store-and-forward concepts.

Explore size-based network categories—local area network (LAN), metropolitan area network (MAN), and wide area network (WAN)—covering ownership, speed, delay, and fault tolerance from buildings to continents.

Trace the evolution of wireless communication from 1g analog cellular to 5g, highlighting digital 2g gsm, 3g broadband, and all-ip 4g with lte and wifi.

Explore global system for mobile communications architecture in 2g networks, including base station subsystem, network and switching subsystem, and features like sms and emergency calling.

Explore the long term evolution 4G architecture and its evolved packet core. Learn how eNodeB, MME, HSS, and gateways connect via S1, S11, and X2 to enable mobility and data.
