Radio Spectrum Inventory: A 2010 Snapshot — Canada

Chapter 12–Licence-Exempt Devices

12.4 Trend Charts

Use of licence-exempt devices has increased significantly in the last 10 years and is expected to continue increasing. In the past six years, more than 60,000 models of consumer devices have been made available, with approximately 60% in Wi-Fi bands.

The following graphs show the number of models and the year that the models were available in Canada for ISM and/or consumer device applications.
