The European Union requires all member states to realize the conversion from analog TV to digital TV since 2012, and release the resulting "digital dividend" frequency band to stimulate the development of wireless services. The specific plan is to use the 790MHz~862MHz sub-band for wireless services such as 3G and 4G mobile phone video Internet access and downloading, to achieve the goal of full coverage of high-speed broadband in the EU by the end of 2023, and to promote the development of cross-border e-commerce and the formation of a single wireless market in the EU .
