Course Description

This training course is for professionals who need to stay competitive in today’s job market with up-to-date knowledge of technologies, products and services in the Mobile Telecommunications Industry. Topics include radio/spectrum/mobility terms and definitions; wireless broadband, cellular, WLAN , grids and short-range networks; devices such as smartphones, sensors; and multimedia, applications, and services.

The training will first introduce terms and definitions to understand this industry such as radios/antennas, basestations/access points, key Air interfaces (TDMA, CDMA, OFDM), key applications such as location, voice, data, video and broadcasting, and Key Performance Indicators (capacity, bandwidth, throughput, transmission, reception, delay, latency, etc.). The course continues with a presentation of wireless systems architecture: the protocol OSI TCP/IP reference models with physical, data link, network, transport and services/application layers as they apply to systems in use today. The last part of this training will cover prevalent products and standards in the market place such as 3G/4G Cellular, home RF, Satellites, GPS/Location, wireless sensors, RFID, Android and iOS smartphones, and CDN/Cloud services.

This is a basic and general introduction to wireless communications. It covers:

  •  Definitions
  •  Networking issues (MAC , network and transport layers)
  •  Wireless devices, services and applications
  •  Network, devices/terminals, and resource management

The course begins with a one hour discussion of basic definitions and basic principles and you will gain an understanding of the:

  •  Difference between wireless and mobile as they are two different concepts and have their own distinct technical issues
  •  Reach the wireless industry has around the world
  •  History of wireless coming to age

You will learn about wireless transmission and how antennas come into play. Air interface techniques, multiple access and key applications of wireless are covered. Cellular networks and systems; handover and spectrum allocation methods are explained. You'll understand the difference between wireless networks and fixed networks. RFID and how it works in medical implants and vehicular communications is included in this lecture. Learn more about the iPhone Apps development, Android / htc and Symbian / nok. Short self-test questions throughout the course help course participants test their understanding.

This course does not cover:

  •  Radio propagation models
  •  Radio modulation and equalization techniques
  •  Source or channel coding, speech coding, or other signal processing aspects
  •  Software-centric aspects and standards are also not addressed

Who Should Attend

This is an introductory level 1-day course for individuals interested in an overview of wireless telecommunications. A basic understanding of RF and wireless fundamentals is useful but not mandatory. In addition, it is assumed that students are knowledgeable of information technology in general, and possess some basic familiarity with telecommunications, computing platforms, mobile devices and networking. This course may be used as introductory training for students pursuing IEEE’s WCET professional certification. It is also ideal for anyone selling wireless products and services who wants a more firm grasp on what the technology in the products they are selling is, the fundamentals of what it can do and what wireless communications professionals on the engineering front are working on developing for future applications.
