When TRUE Corporation started to consider the full broadband wireless office concept in 2003, they had approached a few vendors who could support wireless LAN equipment.
However, NEC was not in the list of vendors for the wireless LAN solution. At this stage, NEC had not yet announced the UNIVERGE products and solutions. When top executive of TRUE visited NEC in late 2003, NEC introduced the UNIVERGE concept for broadband IP solutions and introduced the UNIVERGE WL series, which is designed with enterprise class security and management.
The customer was cautious about the wireless security and NEC had proposed the solution to meet their expectations. Although the customer had already short listed a vendor for the wireless LAN solution, they requested NEC to make a proposal in Bangkok and lease a system for evaluation in the customer’s premises.

CHAPTER1: Introduction of Solution

2nd Enterprise Communications Solutions Division

The broadband environment is rapidly growing for home users and the ratio of broadband users at home exceeded more than 70% in Japan. Japan is currently offering one of the best broadband solutions for home users, however most enterprise users are still deploying narrowband solutions. It is expected that the enterprise will rapidly adopt broadband within the next few years.
In Japan, IP Telephony service, which is called 050 service, was introduced in October 2003. To access the IP Telephone network, the user must dial 050 followed by carrier access code and telephone number.Current telephone charges vary from local calls to long distance calls to IDD (International Direct Dialing) calls where current rates are based on distance. However, in most cases IP telephone service is billed at a flat rate regardless of distance in Japan and even free between users subscribed to the same service provider. This becomes a tremendous cost savings for enterprise customers and can be the trigger for enterprise customers to consider switching to IP telephony. But are there any other benefits to consider in introducing broadband and IP telephony in the office?

In Japan, IP telephony service, which can interconnect with existing PSTN, has been offered fully by many ISP since the second half of 2003. This service uses 050 for head telephone number. This IP telephony service can provide free-call within the ISP group, and drastic reduction of international and long-distance call charges.
The deployment rate of xDSL (Digital Subscribers Line) and FTTH (Fiber To The Home) are growing rapidly in recent years, so it becomes possible to use real-time streaming service such as moving picture, which requires broadband service (see Fig. 1). Furthermore, broadband service is available anytime and anywhere, because broadband is also offered in the mobile field.
Thus, IP Contact Center which can provide wide range of communication options, accompanying the spread of IP telephony services and broadband services, is likely to take off from the second half of 2004.
Some benefits of IP Contact Center, includes lower communication cost, the expansion of the broadband service by integrating image and data, and the possibility of the responding to a call response anywhere.

RADIOSCAPE applies the latest propagation analysis engine and is useful for system design of various wireless systems, such as wireless LANs, cellular phones, Bluetooth, UWB, and RFID.


In this paper, we discuss “Session Traceability Technologies,” which realize high quality and high reliability communication that up until now was difficult to experience within a legacy IP network. With this technology, we can provide network node system that handles sessions’ behavior (either TCP or UDP, or whatever) by utilizing end-to-end information from network, servers and hosts, as well as IP and link level information that reflects network local status. Some of the benefits of the system are as follows. For example, 1) attacks, malfunctions and performance bottlenecks over entire business system consisting of clients, servers, storages, and variety of network elements can be quickly identified, 2) application execution quality is increased by eliminating any possible obstacles to the performance, 3) a broader decentralization of such an environment is supported by increased throughput and quality of long distance communications. By incorporating these technologies into the UNIVERGE product line, it will improve communication quality and service availability of dynamic collaboration systems over broadband networks.

From the Speech at Network Summit 2004

Senior Vice President and Member of the Board

A ubiquitous environment is a society where everything and everywhere are always connected with a network. Japan is rapidly becoming a ubiquitous environment with the evolution of broadband and mobile networks.
Currently the number of a broadband network service subscribers is growing and expanding rapidly, and has exceeded 16 million persons (as of September 2004). This service exceeds South Korea which is one of the leading nations in broadband, and is the fastest in the world as well as the most affordable.
Also in the realm of mobile networks, Japan has the highest ratio of Internet service contracts for cellular phones. Moreover, new 3rd generation cell phone services, which can be thought of as mobile communications going broadband, are beginning to spread in earnest, while the terminals (handsets) themselves have evolved to gain various capabilities such as banking functions and camera functions. It could easily be said that the mobile terminal has indeed evolved into a ubiquitous terminal.
What’s more, Japan has also gained the world’s No.1 market share in major fields in the digital consumer electronics market such as digital camcorders and cell phones equipped with digital camera.
Added to this, due to the advent and spread of terrestrial digital broadcasting, the convergence of broadcasting, broadband, and mobile service domains is anticipated for the future.
Furthermore, in regards to governmental IT policy, the Japanese Ministry of Internal Affairs and Communications (MIC) has launched the u-Japan concept. By realizing this concept, the ministry is predicting that the ubiquitous network related market, including the ripple effect to peripheral businesses, will expand to 120,500 billion yen by the year 2010.
Japanese enterprises should take maximum advantage of this world-leading ubiquitous environment. NEC believes the companies that master this ubiquitous environment for their own business purposes will be the true winners.
