NEC 3G手机解决方案

手机是移动通信的主要工具，发展速度极快。2000年以来，由于市场渗透率很高，尚未拥有手机的消费者数量有限，手机发展速度开始减缓。目前，手机市场的主要消费者是那些换机用户。

预计第三代手机将受到消费者的热烈欢迎，并进一步刺激换机需求。全球各地的电信公司正在准备部署3G移动通信网络。

第三代手机具有新一代业务功能，它们可利用2GHz的高频波段所具备的高传输效率，提供带宽达到2Mbps的高速通信服务。这种带宽可以满足多媒体通信（譬如动画传送）的需要，一个典型的例子就是在手机上观看电视。这将彻底改变手机的应用方式。

为了实现3G商用，手机必须经过一系列技术改进。这些挑战包括在保持高速通信、高性能信号处理和提供很高的内存容量（用于多媒体处理）的同时，降低终端的功耗。作为半导体厂商，我们需要迎接这些挑战，提供最佳的解决方案。

3rd generation mobile phone
Mobile phone (mobile communication) use has undergone the changes shown below.

1st generation mobile phone (1G):
Used mainly as a car phone service and was provided using analog technology.

2nd generation mobile phone (2G):
Used digital technology (GSM, PDC, TDMA). Other services such as the i-mode in Japan, GPRS in Europe, service followed, and were referred to as 2.5 generation (2.5G).

3rd generation mobile phone (3G):
Uses high-speed communication and the highly efficient W-CDMA technology. The first 3G service in Japan was NTT DoCoMos FOMA, which started in October 2001. The current transmission speed is 348 kilobits/second and its ultimate goal is 2 megabits/second.



High-end mobile terminals have performance capabilities equivalent to 10-year-old PCs. They require high-speed signal processing, advanced image processing, and high-density memory mounting technology. To meet these demanding requirements, NEC Electronics will use the following three approaches.

(1)
NEC Electronics supplies two types of CPU: one for performing communication processing (digital base band) and another for processing sophisticated applications such as GPS and sound sources for termination sound, with striking improvements in quality.

(2)
In 3rd generation mobile phones, LCD (liquid crystal display) components are shrinking rapidly, and more multi-paneled products are expected to appear. NEC Electronics is therefore offering LCD driver/controllers for the smooth operation of color TFT and large panels.

(3)
In order to perform the processing described above, a number of high capacity memory types are required. At the same time, only a limited amount of space is available inside the mobile phone and the physical memory size must be kept as small as possible. To satisfy these contradictory requirements, high-density memory and custom IC mounting are used. A package solution will be provided that places everything into a single package using system in package (SIP) technology.

NEC Electronics will also provide various devices types that can be used with conventional 2nd generation mobile terminals. Please see the following block diagram.
