Thumb Movement to Redefine New Mobile Broadband (PDF- 231K)

EMOBILE Ltd, established in January 2005,was awarded a mobile license as a new operator in Japan and launched the service in Spring 2007, entering the mobile industry with fresh vision. Japan is widely regarded as the world's most advanced 3G Market. When EMOBILE, an innovative 3G operator in Japan, wants to develop a new generation of mobile communications service for Japanese subscribers, the biggest challenge facing the operator is not only strategic marketing, but also the network solution itself.

Public "thumbing" hastens the birth of green mobile broadband in Japan

When it comes to using a cell phone, you can say the Japanese are very innovative. In Japan, cell phone users are discouraged from talking on their cell phones in public places, especially in metro. Thumbing has become a type of cultural activity that there are masses of people tapping away at their cell phones enjoying games, videos or mobile TV. EMOBILE has locked this in as their target. Adopting Huawei's full performance HSPA solution, EMOBILE can deliver an excellent broadband service with the peak rate 7.2Mbps and less latency, which can meet the requirements of mobile multimedia application. Meanwhile, EMOBILE issues users Huawei USB modems which are compatible with both Windows and OS operating systems. This amazing gadget is so highly regarded that its appearance in stores is an occasion for celebration.

Further more based on advanced broadband radio technologies, including DPD and A-Doherty, Huawei increased power amplifier efficiency of base station up to 50% .In additional, Huawei's Distributed Node B do not need air-conditioners that cause noise pollution and specific equipment room. All these are one part of Huawei's Green Sites Solution, which can help EMOBILE to save 60% site power consumption.

Leaving the "hot spots"

When a network's bandwidth and speed are assured; the next question that pops up in consumers' minds is whether they can truly use the mobile broadband anywhere as advertised. As you know, WiFi access is restricted to "hot spots," and indoor signal levels of traditional 3G networks are usually too weak to support data applications.

From the beginning, EMOBILE designed their mobile broadband with an integrated approach in mind to solve the indoor coverage issue. EMOBILE adopted Huawei's indoor Distributed Node B System (iDBS) to accommodate full coverage inside buildings, subways, and tunnels. In Tokyo's Yakima business complex, other operators have installed many low-capacity repeaters inside, which makes future expansion and maintenance hard. EMOBILE recently deployed one iDBS system, which supports up to 12 cells and connects as many as 768 antennas, bringing high capacity and wide coverage to users inside the complex. EMOBILE also offers a VIP data transfer service through a simple data configuration; no costly network rebuilds are required.

IP technology enables sizeable transmission savings

In addition to providing a radio access network, EMOBILE needed to improve its transmission efficiency because of its new HSDPA service's extra bandwidth requirements and asymmetrical traffic volume needs. Ultimately, only an IP transmission solution was able to provide the required data processing capability.
When it comes to advanced IP technology, Huawei has built itself an enviable reputation for successfully combining both data and mobile communication. Thanks to Huawei's IPRAN solution, EMOBILE is able to merge RNC with its core network equipment in Tokyo. As a result, EMOBILE benefits from the ease in maintenance and can effortlessly deploy Node Bs all over the country using IP transmission.

Since EMOBILE can use its exiting IP transmission resources, it does not have to build an additional transmission system or rent E1s for its 3G equipment.
