upload Mobile Voice Upgrades to HD
Although mobile data is now 33% of average revenue per user (ARPU) for some operators, voice remains wireless’ killer app. That’s one reason why a growing number of operators — including 3 and Orange — are launching products aimed at improving voice quality. “HD voice” uses a codec that supports a wider
Mobile Backhaul Spending Tops $7.2 Billion
As the number of 3G, LTE and WiMAX networks grows, so does the market for backhaul. In 2009, backhaul equipment spending totaled $7.2 billion worldwide. It’s on track to hit $10.4 billion by 2014, according to a recent Infonetics Research report. ABI Research is equally bullish, predicting a fivefold
revenue increase between 2009 and 2014, with a sharp increase after 2012. Both firms also expect microwave sales to remain strong. In 2009, TDM, Ethernet and Ethernet- TDM microwave equipment was 81% of all backhaul sales, Infonetics found. “The Ethernet-only microwave segment is poised for rapid
growth over the next few years, outperforming hybrid TDM/ Ethernet solutions,” said Richard Webb, Infonetics’ directing analyst for microwave. n
range of audio frequencies: 50–7000 Hz versus the 300–3400 Hz in conventional handsets and networks. That clarity should benefit mobile operators by giving them another way to differentiate themselves, especially in the eyes of business customers and other people who talk hundreds or thousands of minutes per month. Noticeably better voice
quality also might convince some customers to talk longer and thus upgrade to a bigger bucket of minutes — or shift all of their voice spending to wireless. “Price per minute won’t go

up for HD voice subscribers, but it may not erode as quickly as for subscribers to conventional services,” said Fritz Jordan, ABI Research principal analyst. By 2015, 487 million people will have an
HD-enabled handset, ABI predicts. The firm expects growth to increase suddenly in 2013 and then “skyrocket” in 2014, all because on the network side, deploying HD voice is relatively quick and inexpensive. “Newer 3G networks — those deployed since about
2005-2006 — can already use the new format and require only a software update and a changeover to HD handsets,” Jordan said. “That’s why HD voice, unlike most technologies, will first find traction in developing markets: Eastern Europe, Latin America, Middle East and Africa. In North America and Western Europe, 3G infrastructure installed earlier in the decade must be changed to a new format.” n
