For DRB, Canada has adopted the international ITU For DRB, Canada has adopted the international ITU standard based on the ETSI Specification of the Eureka-147 standard based on the ETSI Specification of the Eureka-147 DAB System for use in the worldwide frequency allocation DAB System for use in the worldwide frequency allocation for DRB in the band 1452-1492 MHZ (called L-Band). for DRB in the band 1452-1492 MHZ (called L-Band).

This DRB system is based on a multi-carrier wideband This DRB system is based on a multi-carrier wideband transmission system with a nominal bandwidth of 1.536 transmission system with a nominal bandwidth of 1.536 MHz which allows the broadcasting of 2.304 Mbit/s MHz which allows the broadcasting of 2.304 Mbit/s (roughly 1.2 Mbit/s useful) per channel, and therefore to (roughly 1.2 Mbit/s useful) per channel, and therefore to multiplex together several radio and data services. multiplex together several radio and data services.
