4G-LTE filter

In rural areas, however, the major operators asked to use part of the UHF band.

Since the UHF frequency band is not expandable, it was agreed that television broadcasting should limit its number of channels.

[2] Digital dividend to frequency 698 to 806 MHz (TV Channels 61 to 69) assigned by the plan for the New UHF Frequency Band distribution agreed in The World Radio Congress (WRC-07) which identified 108 MHz of Digital Dividend Spectrum from 698 to 806 MHz for ITU-R Regions 2-1 and nine countries in Regions 3-2, including China, India, Japan and Rep. of Korea.

[3] This Digital dividend is used to improve the coverage of the 4G-LTE new standard in rural areas, needed with the arrival of 4G-LTE and requires therefore the redistribution of UHF frequency band.

Starting from January 2015 (in some countries), the main mobile operators will begin to deploy their networks of very high band width "True 4G" or LTE using the frequency previously attributed to TV Channels 61 to 69, which is known as "digital dividend".
