Norway is the first country to implement a national FM radio analog switch off, in 2017, however that only applied to national broadcasters, not local ones. In many countries, it is expected that existing FM services will switch over to DAB+. The majority of these services are using DAB+, with only Ireland, UK, New Zealand, Romania, and Brunei still using a significant number of DAB services. As of 2018, 41 countries are running DAB services. An upgraded version of the system was released in February 2007, called DAB+, which uses the HE-AAC v2 audio codec. The original version of DAB used the MP2 audio codec. Although DAB reception quality degrades rapidly when the signal strength falls below a critical threshold, whereas FM reception quality degrades slowly with the decreasing signal, providing effective coverage over a larger area. DAB is more robust with regard to noise and multipath fading for mobile listening. However, the sound quality can be noticeably inferior if the bit-rate allocated to each audio program is not sufficient. It is generally more efficient in its use of spectrum than analogue FM radio and thus can offer more radio services for the same given bandwidth. The DAB standard was initiated as a European research project in the 1980s. Digital audio broadcasting (DAB) is a digital radio standard for broadcasting digital audio radio services, used in many countries around the world, though not North America.
