Mobile Services are usually offered over a mobile communications network like UMTS and requested from mobile devices like ordinary mobile phones, smartphones, or laptops. Compared to conventional information and communication services as known from the Fixed Internet, Mobile Services are exposed to several restrictions, for example, limited bandwidth and increased latency, reduced computational power and memory of mobile devices, changing network addresses as a result of the users’ mobility, and many more. On the other hand, however, they open up a broad range of new and sophisticated applications in areas such as navigation, context-awareness, or ubiquitous and pervasive computing, to name only a few.

This course starts with a brief introduction into the fundamentals of mobile services and a short overview of underlying network infrastructures such as GSM, UMTS, and other systems. This includes a short discussion about the particular problems these networks imply and a general overview of the special features they offer, for example regarding the different types of mobility support and associated mechanisms. After that, the course introduces different service platforms and infrastructures and demonstrates their realization and operation. The following topics are covered:

  • Types of mobility and overview of mobile service classes
  • GSM/UMTS/LTE Overview
  • SMS and MMS
  • Mobile Internet and Web
  • iPhone and Android Apps and Marketplaces
  • IMS Services
  • Advanced Services (Mobile Payment, Mobile Instant Messaging and Presence,…)
  • Location-based Services

The course concludes with an overview and discussion of latest trends and developments.

G. (2011). Elementary statistics: A step by step approach: A brief version. (6 th Edition or later). McGraw Hill O b j ec tiv e : The overall goal of the course is to present an introduction to statistics that emphasizes working with data and understanding statistical ideas. The emphasis on application will be achieved by numerous homework and in-class worksheets. You will also be tested three times over the semester on your understanding of the concepts discussed in the course. Grad in g: The course breakdown for your final grade will be as follows: Homework Assignments: 22% (100 points) Reading Quizzes 12% (50 points) Exam #1 22% (100 points) Exam #2 22% (100 points) Exam #3 (Final Exam) 22% (100 points) The usual 90+(A)/80+(B)/70+(C)/60+(D) grading scale will be used. Plusses and Minuses will also be awarded within those ranges. Black b oa r d L e a r n : Blackboard Learn will be used extensively throughout the semester. All lectures, homework, and additional course information will be posted on the site. Remember to check the site frequently! ht t ps: / /ual ea ac kbo a rd. c om/ Cal c u lato r : You will need a calculator that performs basic mathematical operations: add, subtract, multiply, divide, and square root. It will also be helpful to contain a factorial button (!) Please bring this calculator with you to class. We will be doing example problems nearly every day in class, so it will be helpful to perform the calculations as we do them in class. I recommend the CASIO FX 260 Solar School, TI 30X versions, or TI BA II Plus, all are relatively inexpensive. All are sold at the University Supply Store. L ec tu re s: All lectures will be in PowerPoint format and will be posted to the Blackboard Learn website prior to class. It will be to your benefit to print out the slides and READ them prior to arriving to class.
