Wireless Telecommunications

Course Code: WLS 5000

This course introduces the air interface between the transmitter and the receiver in a communications system. The frequency spectrum is broken up into bands of operation. Transmission line parameters are studied in order to make a sensible selection of transmission line to conduct power to the antenna with maximum efficiency. Antennas are studied with the aim of directing the signal into specific directions in a communication link. Propagation of electromagnetic radiation is studied in order to predict proper operation of a system under varying conditions, frequency and distance.

Course Code: WLS 5001

This course introduces the air interface between the transmitter and the receiver in wireless telecommunications systems. Frequency bands are discussed, and transmission line parameters are studied in order to ensure that the maximum amount of transmitted power arrives at the receiver. Learners will employ transmission line theory in order to select the appropriate transmission line and/or antenna that will transfer signals in wireless systems with maximum efficiency. Antennas are studied with the aim of ensuring that power is effectively and efficiently radiated, and launched into the desired space surrounding the antenna. Propagation of electromagnetic radiation is studied in order to predict proper operation of a system under varying conditions, frequency and distance. Satellite systems and Global Positioning System (GPS) communications will also be covered.

Course Code: WLS 5002

This course explores mobile communications systems and how information travels from your mobile device to the cellular base station. Topic covered will include RF transmitter and RF receiver, analog and digital modulation, the cellular concept, handoff, as well as trunking systems.

Course Code: WLS 5003

The course prepares students for entry-level positions in wireless and networking industries. The first half of the course concentrates on developing basic troubleshooting skills in electronics, radio-frequency (RF) and communications circuits used in wireless systems. The DC power plants in cell sites and grounding concepts will be studied. In the second half of the course, fundamentals of telecommunications are reviewed along with a detailed study of digital transmission systems, pulse code modulation (PCM) and T-Carrier systems. The course concludes with the study of data link layer concepts.

Course Code: WLS 5004

The course will take students from introductory networking concepts to implementing networks in different configurations using switches and routers. Students will learn about the Open Systems Interconnection (OSI) model and the protocols associated with each of the layers; the different Ethernet standards; IP design with variable length subnet masking; configuration of switches and VLANs; configuration of routers using different routing protocols; and introductory concepts to internet security. By the end of the course, students will be close to having the knowledge required to obtain a networking certification.

Course Code: WLS 5500

This course combines microwave technology and fibre optics technology to take advantage of many of the same properties like reflection, refraction and propagation of electromagnetic waves though waveguides that governs both technologies. Also studied will be differences between the technologies: very different wavelengths, and types, and sizes, of waveguides will be introduced. To enhance learning, detectors, waveguides and other components, and experiments will also be a part of the course. For the microwave portion the principles and unique techniques employed in the telecommunication field will be studied. In addition, selection of suitable waveguides, impedance matching of discontinuities, return loss and noise measurement are also examined.

Course Code: WLS 5502

This is a practical course designed to provide students with the opportunity to apply the technical knowledge they gained in semester 1 to a practical setting. In semester 1, students develop a proposal for a practical project that is similar to what one would find in industry; in this course, students take their completed proposal and move it forward from design stage to finished product. In special cases, an approved research project may take the place of the practical project, but only with the professor's approval.

Course Code: WLS 5503

The student will study the fundamental principles behind digital modulation techniques used in modern voice and data communications systems. The latest cellular PCS systems are studied with an emphasis on CDMA and GSM. Next-generation systems will also be discussed.

Course Code: WLS 5504

The student will demonstrate a comprehensive knowledge and understanding of the architectures, protocols and frame transport mechanisms of Asymmetric Digital Subscriber Line (ADSL), Broadband Integrated Services Digital Network (B-ISDN), Synchronous Optical Networking (SONET), Frame Relay, and Asynchronous Transfer Mode (ATM) technologies employed in local area network (LAN), wide area network (WAN), and wireless internetworking system. Voice over Internet Protocol (VoIP) technology will be studied in detail and the H.323 multimedia standards will be examined and compared with Session Initiation Protocol (SIP) protocols. Deployment issues will be analyzed in terms of speed, complexity, latency, packet loss, jitter and cost. Network and Internet security protocols (e.g. Internet Protocol Security (IPsec)) will be discussed and security parameters for different networks and corresponding protocols will used to configure network devices. The course concludes with an introduction to next generation technologies such as Multiprotocol Label Switching (MPLS), Virtual Private LAN Service (VPLS), Metro Ethernet, Fibre Channel (FC), FCON and GPON.

Course Code: WLS 5505

This course describes the infrastructures, components and protocols of a wide range of wireless technologies. The course commences with a brief review of networking fundamentals including software and hardware used for interconnection of traditional wired networks. Existing wireless technologies such as global positioning satellite (GPS), cellular digital packet data (CDPD), general packet radio service (GPRS), infrared (IR), and local multi-point distribution systems (LMDS) will be discussed. Technologies such as Bluetooth, digital audio broadcast (DAB) and IMT2000 will also be addressed. The student will be introduced to network operating systems (Novell NetWare or MS Windows 2000). A detailed study and analysis of the IEEE 802.11b WLAN standards will be examined.
