  • Ericsson and Qualcomm make TD-LTE voice advance

    Circuit-Switch Fallback (CSFB) is a mechanism currently used to provide voice services to LTE devices, by signalling an LTE device to "fall back" to the 2/3G network to make or receive a voice call. It has been used in LTE FDD devices and networks, but now Ericsson has said it has become the first to demonstrate voice fallback for LTE TDD (TD-LTE) .

  • VoLTE vs. VoIP: how operators can exploit the potential difference

    Service platform provider OpenCloud is writing two articles for Mobile Europe on the opportunities and challenges of voice in LTE networks. This first one outlines the basic issue - that OTT players have more opportunity to grab market share in LTE, given the better latencies and higher capacities of LTE. But it also argues that there are still advantages for operators, such as service ubiquity, and their background in offering value added voice services.

  • How the iPhone 5 illustrates the RF complexity facing device vendors

    The iPhone 5 has, as you will probably know, been released in three flavours of spectrum support. You might be wondering why device manufacturers don't just fling in a whole load of RF front ends to cover all possible combinations. The answer, of course, is power and space. Here, Nujira's CMO Jeremy Hendy takes a look at the iPhone 5's likely internal RF (Radio Frequency) and PA (power amplifier) structure, and gives a good explanation as to the decisions a designer like Apple faces when it decides which spectrum bands to include. Nujira is a developer of the "envelope tracking" technology Hendy mentions.
