Digia releases Qt 5.0

Digia the company that has taken over the development of Qt (from Nokia) has released version 5.0 of the toolkit. This maintains compatibility with Qt 4.

Qt 5 benefits include:

  • graphics quality
  • performance on constrained hardware

  • support for C++11
  • HTML5 support with QtWebKit 2
  • a vastly improved QML engine with new APIs

Qt 5 also supports OpenGL ES (the version of Open GL that is optimised for embedded systems).

Qt supports a wide range of operating systems including Windows, Mac OS X and Linux, embedded operating systems such as embedded Linux, Windows Embedded as well as the most widely deployed real-time operating systems for embedded devices – VxWorks, Neutrino and INTEGRITY – and popular mobile OSes.

Digia is maintaining 2 versions of Qt, the commercial version and a 30 day free trial is available from qt.digia.com and the open source version from qt-project.org.

Ofcom announces bidders for 800MHz and 2.6GHz auctions

Ofcom the super regulator that covers amongst other things radio spectrum has announced the bidders that have been accepted for the 800MHz and 2.6GHz spectrum auctions (a total of 250MHz is being made available). The details of who is bidding for what has not been made available.

Each of the following paid a £100,000 deposit and the actual auction will take place in early 2013.

  • Everything Everywhere Limited (UK)
  • HKT (UK) Company Limited (a subsidiary of PCCW Limited)
  • Hutchison 3G UK Limited
  • MLL Telecom Ltd
  • Niche Spectrum Ventures Limited (a subsidiary of BT Group plc)
  • Telef√≥nica UK Limited
  • Vodafone Limited

The four existing mobile network operators (MNOs) EE, 3UK, O2 (Telefonica) and Vodafone were expected to bid and will probably bid for the 800MHz spectrum.

BT was a preferred outsider and will probably be bidding for 2.6GHz spectrum.

HKT's parent PCCW already has a nationwide 3.4GHz license (but it's a weird LTE band) but they have launched an LTE-TD wholesale service in the London area, so they may well bid for 2.6GHz spectrum as at least this is a common worldwide LTE band.

MLL already have a low power GSM license and also will probably have bid for a 2.6GHz license, especially as they are developing their own LTE stack (via a 3rd party).

Next year Ofcom will announce which bidders bid for what spectrum.
