A review of the OSI/Internet protocol stack with focus on the issues that are critical in wireless network implementation. The unit outlines the effect of every layer in the overall performance of a wireless network.
This unit starts by giving the reader a brief overview of the concept of "Link Budgets" in order to provide a clear picture of when, where and why the choice of antennas and cables matters in wireless implementations. Thereafter, the unit covers types of antennas, polarization, isolation and coaxial cables and connectors.
A general introduction to basic physics relevant for wireless networking.
The unit focuses on the importance of having a good implementation plan to produce a good budget and discusses how to budget and plan for a wireless network.
Competition in Telecommunications provides an introduction to the economics, business strategies, and technology of telecommunications markets, including markets for wireless communications, local and long-distance services, and customer equipment. The convergence of computers, cable TV and telecommunications and the competitive emergence of the Internet are covered in depth. A number of speakers from leading companies in the industry will give course lectures.
Step-by-step guide to building your own "cantenna" - a directional antenna made from a tin can.
This unit gives some general guidelines that are important to keep in mind when procuring wireless devices. The unit focuses on what criteria that you must have clear before you can select a product for your implementation.
An overview of the different roles in a network that can be filled with a Linux computer. Brief run-throughs of configuration and example software packages for each role.
High-level introduction to mesh networks.
This unit serves as an introduction to the software A Radio Mobile, a radio simulation tool for outdoor environments. The focus of this unit is on the understanding of the different building blocks of the software. Rather than understanding how to simulate only one specific type of wireless infrastructure the learner should be able to apply the methodology to any kind of wireless system.
A general introduction to radio link calculation with many hands-on exercises.
How to configure wireless access points and routers based on general principles and clear motivations.
An introduction to selecting hardware, and installing and configuring a wireless device on your client computer (laptop, desktop). The unit covers installation under both Linux Windows (XP).
The unit provides a general guide for establishment of communication towers and masts. It is practically oriented and presents each step of the process in chronological order.
The unit presents a goal-centric methodology to network management. It focuses first on defining clear goals for a service provider and later describes technical principles and possible tools to achieve the selected goals.
This unit describes security in the context of Information Security. Five general security attributes (Confidentiality, Authentication, Integrity, Non-Repudiation and Availability) are described and later evaluated in the context of IEEE 802.11 (WLAN). The unit finishes by presenting ten security threats that need to be considered in wireless design.
This unit provides a general methodology for troubleshooting communication networks. It introduces two approaches to problem solving, briefly describes the OSI model, and presents the tools available to troubleshoot each of the OSI layers.
An introduction to wireless standards in general and IEEE 802.11 in particular.
