“Mobile internet finally becomes a reality” That’s the claim of Datawind, manufacturers of the Pocketsurfer2.
Pocketsurfer2 is a handheld device that delivers the full power and original graphic intensity of the internet rapidly and wirelessly to the palm of your hand. The PocketSurfer 2 has its own in-built GPRS antenna and SIM card which means it can connect itself straight to the mobile network to get you online immediately, you don’t need any other bits and pieces at all, just get it out of the box and go! You are not dependent on WIFI access and no Bluetooth connection with a mobile phone is needed either. The PocketSurfer2 allows you to browse the web in its original HTML layout, with full graphics, Java support and other complex web functionality on a 640 x 240 colour widescreen display. An integrated mouse pointer and a full format, backlit QWERTY keyboard must make it one of the most usable hand-held web device around. The rich user experience of the PocketSurfer2 offers Continue reading Datawind Pocketsurfer2 A report by Deloitte for the BBC Trust into efficiency of spectrum use has stated that, in addition to more efficient coding and multiplexing, changes in modulation from 16QAM to 64QAM and future adoption of new technologies such as DVB-T2 and MPEG-4, efficiency improvements in the BBCs Freeview multiplexes over the next five years can also be achieved by reductions in the picture quality of servies. Ofcom has issued a statement setting out what it describes as one of the most important decisions we have ever made: how to award the spectrum freed up by digital switchover, the digital dividend, for new users. The decision matters because the spectrum to be freed up is exceptional in that it can readily be used to provide high bandwidth services over long distances and into buildings, and because the opportunity to put this spectrum to new use does not arise often. Ofcom favours a market led, service and technology neutral approach, arguing that giving spectrum to one use will tend to reduce flexibility and blunt incentives. The one exception to this market led approach is programme making and special events (PMSE) which already uses interleaved spectrum on a large scale. This is an extremely diverse community, and Ofcom considers that it would not be able to take part effectively in an auction. They will therefore award a package of interleaved spectrum to meet PMSE users needs. Licence exempt use of interleaved spectrum will be allowed for Continue reading Digital Dividend Review statement The UK regulator, Ofcom, has published a statement on the framework for managing spectrum used by licence-exempt devices. The Spectrum Framework Review sets out Ofcom’s overall strategy for the management of spectrum through a market-based approach. In line with their duty to maximise the value and efficiency derived from the spectrum, the SFR suggests that spectrum use should be licence-exempt if the value that is expected to be derived from the spectrum under such an approach is predicted to be greater than if spectrum use were licenced. It also notes that, where interference is unlikely, licencing may present an unnecessary overhead. The Licence-Exemption Framework Review extends the SFR by examining a number of specific Continue reading Licence-exemption framework review Jason Buchanan, N1SU, has announced a new digital voice mode based on WinDRM called FDMDV which claims to offer robust digital voice communication with enhanced interference rejection. The new mode requires just 1.1kHz of bandwidth and is claimed to work at signal to noise ratios as low as 3dB. It is based on 15 . . . → Read More: New digital voice mode requires just 1.1kHz bandwidth |
