High-Quality Speech Coding for Mobile

DoCoMo just announced that it has developed speech coding technology, in collaboration with their research labs based in Palo Alto, which will enable better voice quality for mobile phones, yet only requires the low-level computing power of conventional mobile technologies. This new approach apparently targets a wider frequency range of 50Hz – 16kHz, which is approximately the full range of the human voice. By comparison, the frequency range of legacy services is limited to 300Hz – 3.4kHz. There’s a few fancy graphs on this .PDF to demonstrate the performance range.

eMobile Unveils SmartPhone & Flat-rate Price Plan

eMobile Unveils SmartPhone & Flat-rate Price Plan by Mobikyo KKeMobile announced their debut package offering – complete with terminals, data cards and flat-rate HSDPA price plan – today at a Tokyo press conference with company representatives joined by notable industry partners including Paul Jacobs, CEO of Qualcomm, Darren Huston, CEO of Microsoft Japan, and Masafumi Matsumoto, representative director from Sharp. The upstart carrier’s founder, chairman and CEO, Sachio Semmoto (who was co-founder of DDI, which became KDDI), called their newly introduced Sharp EM-One smartphone, “the next-generation mobile broadband device” – which was “designed to deliver always-on broadband at a reasonable monthly flat-rate price.”

The new Sharp terminal is bound to be popular with the same crowd who lined-up to get Willcom’s Zero3 model, also made by Sharp, in late 2005. The EM-One is a touch-screen qwerty-keyboard dual-slider device sporting a 4-inch LCD screen with Japan’s first WVGA (800×480)-resolution screen and Windows Mobile 5.0 (with all the typical office functions). At only 18mm thin, it even comes ready to watch 1Seg digital TV broadcasts and – according to the specs – the unit sports a Marvell PXA270 cpu running at 520MHz with 512MB of Flash memory and 128MB RAM. Perhaps most interesting are the rather agressive price plans, which bundle the device with fixed- and mobile-broadband connection services to attract new customers.

The company also announced four new data cards including a PC Card unit produced by NEC and a USB design coming from Huawei, which will run on the same high-speed network and tabehoudai all-you-can-eat billing model. The new services will be available starting 31 March in five major population areas including Tokyo, Aichi, Osaka and Kyoto. More details after the jump.

3 in 4 Japanese Mobiles Currently Spam-Free

japan.internet.com recently reported on a survey conducted by JR Tokai Express Research on the subject of mobile phones and spam. Over three days at the start of February 330 peope from their monitor group successfully completed a private internet-based questionnaire. The sample was 51.8% feamle, with 26.7% in their twenties, 40.6% in their thirties, 25.2% in their forties, 5.5% in their fifties, and 2.1% in their sixties. I’ve been spam-free on my phone, perhaps because I only sign up with reputable firms. However, my wife has used YNot electronic greeting cards just recently, and has been plagued with a flood of spam from Rakuten partners. Full details with graphs Here.

20% of Japanese Parents Give Children Mobile

japan.internet.com recently reported on a survey conducted at the start of the month by Cross Marketing Inc regarding children and mobile phones. 300 members of their monitor panel who had children successfully completed a private internet-based questionnaire. The sample was split 50:50 male and female, and the ages of their children (some of the respondents had more than one) were 11.0% under three years old, 41.7% older than three but not yet entered elementary school, 30.0% in the first two years of elementary school (aged six or seven), 19.7% in the third or fourth year of elementary school, 28.0% in the fifth and sixth year of elementary school, 31.0% in middle school, and 20.7% in high school or older. Full details with graphs Here.

January Carrier Stats Released

The latest subscriber figures were announced today with good news for SoftBank Mobile and what must be disappointing results for DoCoMo while KDDI continues to lead the pack in over-all performance again in January. We had mentioned that many industry watchers were expecting SoftBanks new flat-rate voice plan – announced in early January – would have an positive impact, and it certainly did. Most surprising was the small month-on-month loss of i-mode customers, the second time in 3 months, for the incumbent.

Cutting Back on Mobile Phone Bills in 2007

NEPRO JAPAN recently published the results of a survey into economising on one’s mobile phone bill. On one day in mid-December of last year they questioned 3,425 people across the three main Japanese carriers, DoCoMo’s iMode, Softbank’s Yahoo! Keitai and au and TU-KA’s EZweb, by means of a public poll available through the main menus of all three carriers’ systems. 44% of the sample were male; 3% were teenagers, 35% in their twenties, 44% in their thirties, and 18% aged forty and over. Similar questions were asked of a similar group around the same time last year, so one can perhaps observe a trend over the past year. Full details with graphs Here.

OKI Unveils Base Advanced Band LSI

Oki Electric has announced their ML7257 [.jpg here] base band LSI which incorporates voice and data communication functions in a single chip. OKI succeeded in including the three types of modulation and demodulation functions defined by W-OAM, as well as all the voice compression functions in a single device. Thus, power consumption is reduced to two-thirds that of conventional DSP-based software solutions. For the CPU core, the LSI uses ARM7TDMI, which is used in many mobile phones and PDAs around the world because of its high-performance, low power consumption and high-code efficiency.

Japan Spectrum Draft Report

Frequency issues may be a gating factor in Japan, where WiMAX penetration depends on how the Ministry of Internal Affairs and Communications (MIC) regulates the usage of the 2.5GHz band. In December 2005, the group offered recommendations for spectrum usage from 800MHz to 81GHz. The MIC study group chose the 2.5GHz band specifically for low-cost broadband mobile wireless services not provided by current mobile-phone networks. An advisory telecommunication council will issue a draft report in September, with a final report due in November.

Japan Number Portability: The Autumn of Discontent

The hottest topic roiling Tokyo’s hot street this month is MNP – mobile number portability.

Details on pricing, dates and procedures that Japan’s carriers will follow to implement the regulator-mandated programme have been posted on WWJ in several items on this topic, including here, here and here.. Analysts, pundits and assorted commentators have all more or less concluded that the net winner will be KDDI/au, while the net loser will be DoCoMo (the jury is still out on Vodafone/SoftBank Mobile). At least some are attributing this pending negative migration to mere probability – as the carrier with the largest customer base, they argue, DoCoMo naturally stand to lose the biggest number of churners – all things being equal. But this analysis is weak and WWJ thinks..

Drink Beer & Win a 1-Seg Digital TV Watch

Asahi Breweries has teamed up with Willcom to give away 5,000 1-Seg digital TV watches. According to the Willcom contest info page: “By inserting W-SIM in a slot, you can make a telephone call and use mail over the microcell network of Willcom.” No info on the hardware specifications, such as battery run time, etc., that we could find in a hurry; however, we’re looking forward to seeing these units popping up around town and are actually just rushing out the door now to buy a flat of brews so we hopefully get one of our own!
