4g or LTE
The first commercial 4g networks have launched, TeliaSonera in selected cities in Norway and Sweden, just Stockholm and Oslo so far, with licences also in Finland
TeliaSonera press release www.teliasonera.com/4g up to 100 megabits per second, apparently, or 20 to 80, depending on source I read about it on TechCrunch First 4G Mobile Network Launches . . . In Sweden :( Quote:
Slightly more detailed discussion on 4G network goes live for lucky few ? The Register Quote:

O2 UK has announced that it's carried out its first tests in Slough
O2 Achieves 150Mbps Download Speed In 4G UK LTE Trial - ITProPortal.com As well as those news items. there seem to be some people starting scares it would interfere with cable TV - maybe there's some misunderstanding of a few things, like frequency allocations like the 800 MHz to be released from analogue broadcast TV, or prospective 2.6 GHz bands due to be auctioned some time or other, or the likelihood of fibre optics being affected anyway. |
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. |
I missed this earlier
Digital Dividend could cost cable TV dear ? The Register The EU is to investigate claims that 4G mobile networks could knock out cable TV, if allowed to deploy in the "Digital Dividend" spectrum. [...] Today's LTE networks (well, network, there's only one right now) are right up at 2.6GHz, well clear of TV signals, but after the auctions LTE is expected to spread rapidly down the dial. |
