4g or LTE

[inquisitor]

I think 4G-technology is still in a very early stage of development. Against the background of missing terminals it's odd to promote a commercial launch, especially when basic services like voice have just recently been specified and first test calls took place only days ago. There's an very interesting blog of Martin Sauter, a telecom engineer and book author, who shares his thoughts and provides detailed explanations at: WirelessMoves

Regarding the digital dividend, 3G and 4G were proven to interfere with DVB-C and DVB-T (see Google Übersetzer). While that issue can be solved for DVB-T by narrower frequency filters in receivers, there's no other solution for DVB-C than skipping the relevant spectrum for cable broadcasting.
