This course provides a introductory technical overview of networking and telecommunications for the engineering practitioner. Topics include voice, data, and video communication system fundamentals, including signaling, frequency concepts, transmission media, multiplexing, spread spectrum, signal encoding, error control, switching, and basic terminology. The OSI and TCP/IP reference models are examined along with the basic concepts of protocols, service interfaces, encapsulation, and layering. The course also covers networking and telecommunication techniques, applications technology, and networking topologies and Internetworking architectures. Specific areas discussed include LAN system fundamentals, such as IEEE 802.3 Ethernet, IEEE 802.11 wireless LANs and IEEE 802.15/Bluetooth; and wide-area systems such as cellular and satellite networks. TCP/IP infrastructure and protocols are extensively covered including IP routing, transport layer protocols, and applications including web, email, and real-time applications such as Voice over IP (VoIP). The course also covers the basic principles and protocols for Network Security (IPsec, SSL/TLS) and Management (SNMP).
