Successful integration of WiFi and or Bluetooth features into a product requires more than simply finding room on the board to place "off the shelf" chips. A proper understanding of how the radios work and the issues that they face will allow you to achieve a successful implementation with fewer expensive surprizes. This two day course provides a working knowledge of how the standards operate to guide your integration efforts.

Learning objectives

Upon completing the course you will be able to:

  • appreciate the relationship between data rates and power consumption
  • follow the evolution of 802.11 standards
  • estimate the operating range of your devices
  • interpret performance measurements of the transceiver components
  • understand how Bluetooth and WiFi transceivers impact each other
