Shall we not build DTT, after WRC 2015

According to the news in the web site of EBU, 470 - 694 MHz will be reserved for DTT & radio microphones not only till WRC 2019, but also till WRC 2023. At the WRC 2023, 470 - 960 MHz band will be reconsidered. It is good news for the DTT business in Europe. But is it a good news for Turkey? As you may well know, Turkey has not yet spend any money on DTT. There is no DTT network, nor a finished frequency allocation tender. Hence, we can say that there is nothing, just NOTHING regarding DTT.  So, in best circumstances, the tender for DTT frequencies can be finished by 2016 & the network would be ready by 2017. Well, the picture becomes interesting from that point. The frequency allocation would be for 10 years, which covers 2016-2026. But, during the WRC 2023, the frequency usage will be reconsidered again. It may be more meaningful to think not to build DTT at all, and start thinking to work on xG mobile networks. I would appreciate for your comments... 

waiting for WRC, thinking of DTT in Turkey

You probably know that WRC 2015, is going to start in 2 weeks. There will be debate on the use of 470-694 MHz. The European public broadcasters, and the organization of the public broadcasters, namely European Broadcasting Union, EBU are trying to secure the rest of UHF band for terrestrial broadcasting.  For the ones out of broadcasting, the frequency band can be thought as the road for the automobiles. When the road is wider, you can put more cars on it. If you squeeze the cars, then it is OK for you to live with a narrower road. That's exactly what happened when the terrestrial television went through the digital transmission. The size of the cars, the bandwidth needed for a TV channel, has went down. Hence, the whole UHF band for analogue TV transmission is more then enough. On the other hand, there was a increasing demand of bandwidth in mobile networks. This demand, caused the release of 800 MHz band to mobile.  With the developments in the encoding technology, the
