Peter Cochrane's Blog: Fat cat telcos are killing the net
Comment Ironically the internet then starts to look like a circuit-switched system à la the old telephone network. And in phase one they would like to groom the traffic carried to increase the efficiency and the earnings per packet. [07 Jul 2006]
The worst kept secret in mobile
Comment A few years ago that might have meant punting out phones and laptop data cards using a form of circuit-switched technology called HSCSD in advance of packet-switched GPRS. The companies behind the latest smart phone launch would love us all to... [15 Sep 2003]
Peter Cochrane's Uncommon Sense: Circuit or packet, clean or dirty?
Comment The move from circuit- to packet-switched IP networks leaves communications companies in a strange position. It was the need for computer communication that created the packet switched philosophy to obviate the need for 100 per cent dedicated... [14 May 2003]
Convergence - put it back on the agenda
Comment Then there are concerns about voice over wide area packet switched, as opposed to circuit-switched, networks - something Peter Cochrane will address in his next 'Uncommon Sense' column tomorrow. If we told you voice and data convergence has arrived... [14 May 2003]
Has Gigabit Ethernet come of age?
Comment In short, this pipe is fat, fast and cheap, leading to rumors that it may be the packet protocol to push Asynchronous Transfer Mode (ATM) and its circuit-switched cronies out of their exclusive oasis they call the WAN. [30 Oct 2001]
The Ovum view: Going over the Edge
Comment It comes in two flavours, a circuit switched variant called ECSD, and a packet switched version called EGPRS. It shows the roadmap from the current second-generation mobile networks (2G), through the intermediate step of data-friendly packet... [02 Oct 2001]
The Ovum View: Avoiding the WAP trap
Comment The data speeds initially promised for GPRS have turned out to be slideware - although in principle it can support throughput rates above 100Kbps, in practice, but currently the actual throughput rates are closer to 10 or 20Kbps, not much above... [29 Aug 2001]
The Gadget Showdown: The Confrontation in the Next Generation
Comment Next up - will the souped-up version of old-style GSM beat the cheeky young packet-switched challenger? The key difference is that it's "packet-switched". BT launched its GPRS service to business users in June 2000, and Orange went live with HSCSD... [27 Jun 2001]
The Bloor Perspective: Java's big hope and Microsoft's major headache
Comment Packet based GPRS services are poised to deliver packet billed applications with better bandwidth than circuit-switched WAP, but the interim nature of the technology and hype-bred anticipation promise heavy weather. [19 Dec 2000]
Power in the palm of your hand - who holds the handheld aces?
Comment The Sagem WA3050 compares to Nokia's latest Communicator in some respects - it's a dual-band GSM phone which promises large screen, high-speed data communication (although it will employ packet-based GPRS rather than the circuit-switched and not... [04 Dec 2000]
Keeping up with the Joneses - the UMTS licence race
Comment These 'inbetween' 2.5G upgrades for GSM networks include GPRS (General Packet Radio Service), HSCSD (High Speed Circuit Switched Data), and EDGE (Enhanced Data Rates for Global Evolution), and all promise speeds somewhere between today's pitiful... [17 Jan 2000]
