During this time, digital replacement technologies have been standardized in an effort to rationalize spectrum use and enhance broadcasting applications with datacasting services and associated program information. Eureka DAB was the first all-digital mobile broadcasting technology to be conceived, developed and deployed. It became a widely adopted standard for digital radio in many countries around the world in the mid-1990s. DAB was officially launched in Canada in 2000.

This paper presents CRC's attempt to increase collaboration and innovation in the field of mobile broadcasting by developing and offering complete end-to-end Free, Libre and Open Source Software (F/LOSS) toolsets for the transmission and reception of DAB and FM/RDS applications and services.1 aLefebvre, François  uhttp://timreview.ca/article/33302292nas a2200145   4500008004100000022001400041245003500055210003200090260004200122520188800164100001702052700001702069700002402086856003602110       2010                        eng d  a1913-610200aEditorial: Mobile (March 2010)0 aEditorial Mobile March 2010  aOttawabTalent First Networkc03/20103 aOpen source software and hardware has become an accepted way of developing new and interesting applications in many information and communication technology domains: operating systems, databases, Web infrastructure, and applications. It's not surprising that with the increasing popularity of mobile handheld devices, users and researchers have explored the power of open approaches to providing innovative new applications and services in this domain. However, unlike personal computers and the Internet, mobile handsets were tightly controlled by mobile network operators (MNOs) who developed a vertical ecosystem by integrating the communication infrastructure, the handheld device hardware, and often the applications installed on those devices. The software and protocols running the mobile communications infrastructure and devices are often standardized by membership-only bodies, where large MNOs and manufacturers have a predominant influence. These players invest significant financial resources into shaping the industry along their vision to gain a competitive advantage. A current example is the ongoing battle about the dominant radio access technology for 4G cellular systems: LTE vs. Wimax. 

These trends have changed recently. Companies such as Google, Nokia, or Openmoko and Industry Alliances such as the Open Handset Alliance are providing the core building blocks, both in hardware as well as software, of increasingly open mobile devices. This issue of the OSBR reviews the relevant trends in the open mobile platform space from a number of perspectives. As the articles in these issue show, there is a lot of exciting ongoing work that brings the power of open source development to the mobile space. This trend is not just confined to the mobile devices as there are also efforts in the development of open mobile infrastructure elements and whole systems.1 aLavigne, Dru1 aKunz, Thomas1 aLefebvre, François  uhttp://timreview.ca/article/329
