Telecommunication is a significant driving force for socio-economic prosperity, and wireless technology has been a fast growing segment of this technological area during the last two decades. Canada, through its world renowned industry, has been a major player in wireless telecommunication, a position that it is important to maintain if this technological area will continue to be dominant. However, further growth of wireless telecommunication depends critically on the availability of radio spectrum for future services. Traditionally, radio spectrum in wireless telecommmunication has been allocated using a fixed assignment policy. However, the proliferation of wireless communication services over the years has exhausted the usable frequency bands, making the spectrum a scarce resource.

电信是社会经济繁荣的重要推动力，无线技术在过去20年里一直是这一技术领域中快速增长的部分。加拿大通过其举世闻名的工业，一直是无线电信领域的主要参与者，如果这一技术领域继续占据主导地位，保持这一地位是很重要的。然而，无线通信的进一步增长关键取决于未来服务的无线电频谱的可用性。传统上，无线通信中的无线电频谱是使用固定分配策略来分配的。然而，多年来无线通信服务的激增已经耗尽了可用的频段，使频谱成为一种稀缺资源。
