Audience

This course is for anyone involved in Wireless communications from those just starting out, those specifying and designing, through to actual installation engineers. It has been designed to ensure that the student understands the components involved in creating a successful radio link. Looks at how radio transmission works, the technical considerations involved and also comparing microwave and or fiber optic transmission to supply the emerging and ever increasing information/communication demands.

Pre-requisite experience

No pre-requisite experience is required to take this course as the subjects covered will be of interest to anyone working in the RF and Wireless fields in any aspect.

Objectives

  • To provide the student with fundamental information to help them understand the basics of wireless systems and infrastructure.
  • Understand the terms used in wireless including unit of measurement
  • Discuss wireless design and the components involved from one end to the other
  • Look at cellular transmission, with past, current and future technologies from 1G to 5G and WiFi
  • Investigate different cabling options and look at Antenna theory and design
  • Show transmission methods including modulation schemes, data rates and spectrum
  • Discuss methods of increasing antenna coverage to meet ever increasing wireless demands
  • Explore the complexities of connectivity including Link Budget, Path Loss, Signal to Noise Ratio, Cell Foot Print and coverage
  • Consider Cell Site Design not only antennas but jumpers, feeders, filters, combiners and amplifier
  • Find out about RF measurements at a Cell site including line sweeping and VSW
  • See how important good connections are and if not, resulting possible PIM issue
  • To provide a look at Microwave backhaul v fiber options and advantages / disadvantages.
