GL Communications has added POLQA (Perceptual Objective Listening Quality Analysis) to its voice quality testing software. The company’s enhanced VQuad and stand-alone Voice Quality Testing (VQT) software both incorporate support for POLQA, also known as ITU-T P.863. POLQA is the successor to PESQ and supports the latest HD voice codecs and network transport technologies with higher accuracy for 3G, LTE, and VoIP networks. Ericsson and China Mobile have demonstrated the first “dual mode” HD voice call between TD-LTE and LTE-FDD, the two different types of LTE. The demonstration included ST-Ericsson’s Thor LTE modem, Renesas Mobile quad mode chipsets, and Ericsson’s LTE TDD/FDD radio solution and IMS platform and was conducted at China Mobile’s booth at the Mobile World Congress (MWC) event in Barcelona. TD-LTE has found favor in China and the U.S.’s Clearwire LTE deployment while the majority of operators are deploying LTE-FDD. D2 Technologies announced its IR.92 VoLTE software will be going on the NVIDIA Icera family of LTE modem chipsets for mobile devices. D2’s software enables carrier-grade voice and SMS-over-LTE capability. The two companies also plan to collaborate on a reference design for RCS, Wi-Fi calling and IR.94 video calls that uses D2’s vPort 4G+ advanced API for IMS features in conjunction with D2’s mCUE 4G mobile client software running on NVIDIA’s mobile processors. NVIDIA’s i500 LTE modem is the second one to implement 4G LTE in NVIDIA’s software defined radio baseband processor, offering category 4 data rates up to 150 Mbps plus 4G HSPA+, 3G and 2G compatability. ZTE has conducted a Voice over LTE (VoLTE) call using Single Radio Voice Call Continuity (SRVCC) for Hong Kong mobile operator CSL, reports Telecom Lead. The VoLTE call handoff was done to a 3G HD voice network with an ”eSRVCC based pre-commercial network,” according to the story, Expect more SRVCC-news out of Mobile World Congress (MWC) this week, as carriers and vendors want to demonstrate progress in moving calls between 3G and 4G networks. GSMA plans to promote its HD voice activities as a part of the Rich Communications Innovation area at Mobile World Congress 2013. Located at the GSMA stand in Congress Square CS80, live demonstrations will be conducted along with presentations by Audience, Deutsche Telekom, Head Acoustics, Orange and Samsung. Look for vendor shirts with the GSMA trademarked HD voice logo if you’re at MWC.
Telefonica has become the first network operator to demonstrate the ability to transfer voice calls seamlessly and without interruption from an LTE network to a 3G network. However, the handover was conducted in a test lab environment simulation – not in the real world. The handover was conducted in Germany at the labs of Telefonica Deutschland and is the first announced demonstration of handoff between LTE to 3G using SRVCC (Single Radio Voice Call Continuity), a standard for call handoff. Handset and network components involved in the demonstration included pieces from Acme Packet, Ericsson, Huawei, NSN, Qualcomm – no surprise there, since they’ve baked SRVCC into chipsets – and Sony Mobile. Publicly traded Telefonica says it will be conducting Voice over LTE (VoLTE) demonstrations at Mobile World Congress (MWC) in Barcelona this month. There’s been angst in the South African trade press regarding the lack of mobile HD voice service. So I’m annoyed about playing semantics for cheap PR. “Contrary to popular belief – HD voice services are here (and sounding great)” issued by DUO Marketing + Communications for client Vox Telecom makes this biiiiig stretch that all is good because Vox supports HD voice over a broadband wireline connection, the Vox Suprafone. “All that’s needed to support the service is an ADSL line Internet account, and a modem/router,” says the product manager. Why, you don’t even need a PC to make calls! The ongoing discussion within the South African media has been about mobile HD voice service on a cellular network. Not what you can plug into a broadband connection… It’s almost as annoying as the “HD sound” vs “HD voice” ambiguities that continue to pollute a discussion on wideband telephony. - Doug Mohney Chunghwa Telecom (CLP), the largest carrier in Taiwan, has launched HD voice service on its 3G-based network, according to a recent news report. Around 500,000 subscribers today can get HD voice service with 21 compatible (i.e. AMR-WB using) devices including the Apple iPhone 5, Sony, Nokia, and HTC handsets. Both subscribers need to be on CLP’s network with compatible devices (as is typical). The carrier expects by 2016 that more than 70 percent of devices (on its network? Google Translate makes it hard to say) will support HD voice. Chunghwa Telecom has over 10 million mobile subscribers, according to Wikipedia. The 2013 HD Voice News third annual report is now being created. Companies that want to contribute and/or update information may email the editor at dmohney@hdvoicenews.com Current deadline for accepting information is March 1. The report should “close” on that day for final editing with a targeted mid-March release date. Local media in South Africa have no idea when operators will deliver HD voice in that country. “South Africa seems to be lagging behind the rest of the world when it comes to mobile HD voice,” writes MyBroadband editor Rudolph Muller. “This includes African countries like Uganda, Mauritius and Egypt which have HD voice services.” MyBroadband says Vodacom is “still investigating” mobile HD voice and has “no specific launch plans” to share at this point in time, while Cell C, MTN and 8ta did not comment on their plans. HD Voice News is willing to speculate that Vodacom is a good candidate to offer HD voice since a couple of Vodafone subsidiaries; Ireland comes immediately to mind. |
