Paper Summary:

The writer asks and answers questions concerning digital radio. Will this format be here to stay or will it just become a stepping stone technology? Will the world decide on a single transmitting format? And most importantly, will the general consumer accept this new technology? The beginnings of digital radio have already been seen. These stations, which are received via satellite, have been used by businesses to provide a variety of digital, commercial-free, music to be enjoyed by their customers.

From the Paper:

"The future of digital radio in Canada relies mostly on the L-Band which Canada introduced to world in 1992. The L-Band is basically a carrier that uses both terrestrial and satellite signals for wireless transmissions. This makes for a carrier that far exceeds that of its predecessors, the FM and AM band, which the government plans to replace by 2010. After digital radio becomes the standard, the CRTC plans on using the AM/FM frequencies for other purposes of wireless transmission. AM radio covers the frequencies of 530KHz to 1630Khz for a bandwidth of 1.1MHz. The bandwidth needed, though, for each channel is 0.01MHz. FM covers the band of 88MHz to 108MHz for a total bandwidth of 20MHz, with 0.25MHz needed per channel. The L-Band on the other hand ranges between 500MHz to 1500MHz, although for digital radio only frequencies from 1452MHz to 1492MHz. are slated. This leaves digital radio with the bandwidth of 40MHz, where 1.5MHz of bandwidth is needed for the 48KHz, 16bit uncompressed audio."
