The industry's discussion of 3G has been boiling for many years. However, many experts still think that 3G is not yet mature, and the maturity of end products is considered to be one of the most important bottlenecks. This is not only related to 3G still constantly modifying the standard and other external environments. More importantly, the increase in the function of the 3G terminal has brought more challenges to the manufacturer. Height integrated technical strength is the development of 3G terminal condition.
■ Investment Commercial is the application foundation of 3G terminal
How can the manufacturer lead to other competitors in the 3G terminal? The essence of this is what the 3G mobile phone should guarantee what function? Different mobile phone manufacturers have different anshes, but at least the current market has no so-called "all-round" 3G mobile phones. NEC's answer is clear that it can be put into commercial and guarantee that the basic functions of 3G are most important, so that other additional features can be increased step by step.
NEC said to invest commercial, means that users should pass on any circumstances and enjoy 3G services. For example, when the user moves from a base station to another base station, the ongoing voice or data service can be switched normally; the QoS of the multimedia service is guaranteed. Since the 3G network device is provided by a number of vendors, and the implemented version is also in the continuous upgrade, the 3G terminal must not only ensure interconnection with different system manufacturers, but also have high functional stability. All of these technical capabilities and practical experiences of mobile vendors have put forward very high requirements. The advantage of NEC is precisely in the rich experience of commercialization. When introducing 3G commercial services in Europe, NEC has also carried out 100% interconnection with 4 network equipment companies. As early as 2002, China began MTNET testing. At that time, many vendors can only take out the same test terminal as the circuit box to participate in the test, and NEC provides testing of mobile phones. In 2003, NEC was tested with a number of famous equipment manufacturers, achieving considerable interconnection rates.
Another challenge of the 3G terminal is whether it is possible to provide a stable application. It is well known that 3G focus is in the data service, so the 3G mobile phone is a client of the mobile communication system, which is very important to the contact capability of the mobile operator server. Prior to 3G, mobile phone manufacturers can be sold by operators, but they have reached the 3G era, even if the communication test may have a variety of applications that can occur properly in real use. NEC has worked closely with 3G operators in 2001 to have a deep understanding of the integral performance of 3G operators system and interfaces, with technical strength to function properly in the terminal level.
from the most basic voice to general data, video download applications, to today's popular visual calls, large-capacity data downloads and other application services, NEC's 3G mobile phone can provide good application support, It has always been acting as a role of the industry. The key reason is that NEC itself has the core technology of 3G terminals, including applications, protocols, chips, etc., especially chips and protocols, are also developed by NEC. NEC is based on full, profound understanding of 3G terminal core technology, and incorporates its own mature terminal design concept, and has developed the most complete, technology-new 3G commercial terminal products, which will naturally be commercially available. The advantage of the mobile phone. For example, in the past 2003, NEC has introduced 3G terminal with visual phone function for NTTDOCOMO and Huangpu, making users enjoy visual call service between international 3G networks, which can be said to create a new one. Life communication method.
3G terminal's launch is not smooth, NEC, the first generation of 3G mobile phones launched in Japan because the standby and talk time is short, not being welcomed. The E606 and E808 launched in Europe have also been plagued by power consumption. After NEC, the physical layer and chip of the phone have been thoroughly improved, and the call and standby time have improved. This is a C616 that is about to be launched in Hong Kong. It is a WCDMA / GPRS-GSM dual-mode product, not only has visual telephone functions, but also combines streaming media play, mobile phone positioning, high quality camera, Bluetooth, memory card, etc. The latest features.
NEC believes that the initial 3G mobile terminal has 3G basic functions, such as video calls, streaming media, high-speed download, etc. Second, due to mobile communication, 3G mobile phones are at the stage of 3G migration from 2G You should also have a seamless switch between 2G and 3G networks, that is, inter-network switches during the call. And this has been included in the next step development plan of NEC.
A copy of the statistical results of WCDMA at the end of 2003 show that approximately two-thirds of the NEC phone are used in the global WCDMA terminal users. Surprisingly, the only manufacturer of 3G terminals and underlying network systems can be provided at the same time as the world, NEC's network system and terminals are almost all 3G networks that have been opened worldwide. Unlike many mobile phones that have recently launched 3G terminal products, NEC's 3G terminal has been put into commercial use in the market for more than two years. From October 2001, the world's first commercial 3G terminal is launched today. NEC has launched 10 3G commercial terminals to the world. He has taken the lead in investing in Japan, Italy, UK, Sweden, Australia. It provides a good support for the 3G business applications of these countries.
