  • 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.

    LTE1800_global_status

    Rival operators who suspect EE has gained a significant advantage over its rivals by deploying LTE in 1800MHz spectrum may have had their fears confirmed by a senior network economist at Deutsche Telekom (DT).

    David Haszledine, Network Economics Manager at DT, told Avren Events' HetNet conference that rolling out an LTE network in 1800MHz spectrum could be a quarter or a fifth as cheap as achieving the same network in 2.6GHz spectrum.

  • DragonWave demonstrates high speed microwave backhaul

    Trials first 2048QAM product in live operator network

    Dragonwave has said that its 2048 QAM radios, launched in May 2012, have demonstrated a three times increase in capacity in a live operator demonstration.

    Three microwave links in Intertelecom's test bed network in Odessa, Ukraine, have been equipped with the 2048QAM radios. DragonWave said that the field test has demonstrated the radios' ability to transport up to 37% more data through existing microwave channels. Through a combination of the 2048QAM modulation, dual channel operation and DragonWave's Bandwidth Accelerator feature, the test also achieved a threefold increase in capacity to more than 1.3 Gbps.

  • SFR to launch LTE and DC-HSPA, plus shared data plans

    Starts on road to shared data plan with multi-SIM offer

    SFR has announced that it will launch commerical LTE services in Lyon on November 28. There will be a "range of devices" available with rates based on new Dual Carrier HSPA tariffs announced today (see below).

    HSPA
    As well as the LTE launch in Lyon, by the end of the year SFR also wants to have 60% of the population coverage with Dual Carrier (DC) HSPA - the version of HSPA that offers a theoretical maximum of 42Mbps.

  • SK Telecom, Ericsson and Altair develop LTE TD-FDD handover

    SK Telecomhas announced that it has developed technology to allow handover between TD and FDD LTE duplexes within a single device — leading the way to dual-mode LTE devices based on a single modem chipset.

    It says that in partnership with Ericsson and Altair Semiconductor it has developed a two-way handover technology that supports both Frequency Division Duplex (FDD) LTE and Time Division Duplex (TDD) LTE - two different modes of the LTE technology standard - in one device, and successfully demonstrated the technology in a moving vehicle.

  • 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.
