IEEE 802.11j-2004 IEEE Standard for Information technology—Telecommunications and information exchange between systems--Local and metropolitan area networks—Specific requirements—Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) specifications—Amendment 7: 4.9 GHz–5 GHz Operation in Japan
This software performs code conversion of Chinese characters,
including GB2312/GBK and BIG5.
It also supports some encodings of Chinese character code which
are used widely in Japan, such as Chinese Writer, cWnn, Nihao,
Zhongwen Qigao, etc.
The idea of the book was born during the time when the second generation cellular system was looming on the horizon.At that time ,the world was divided into three distinct camps as far as looking for a standard: Europe North America and Japan.
The first Third Generation Partnership Project (3GPP) Wideband Code Division
Multiple Access (WCDMA) networks were launched during 2002. By the end of 2005
there were 100 open WCDMA networks and a total of over 150 operators having
frequency licenses for WCDMA operation. Currently, the WCDMA networks are
deployedinUniversalMobileTelecommunicationsSystem(UMTS)bandaround2GHz
in Europe and Asia including Japan and Korea. WCDMA in America is deployed in the
existing 850 and 1900 spectrum allocations while the new 3G band at 1700/2100 is
expected to be available in the near future. 3GPP has defined the WCDMA operation
also for several additional bands, which are expected to be taken into use during the
coming years.
For more than a century, overhead lines have been the most commonly used
technology for transmitting electrical energy at all voltage levels, especially on the
highest levels. However, in recent years, an increase in both the number and length
of HVAC cables in the transmission networks of different countries like Denmark,
Japan or United Kingdom has been observed. At the same time, the construction of
offshore wind farms, which are typically connected to the shore through HVAC
cables, increased exponentially.
RFID networks are currently recognized as one a research area of priority. Research
activities related to RFID technology have been booming recently. A number of ongoing
projects are being funded in Europe, Asia, and North America. According to leading
market analysts, the development of the RFID market is projected to increase from
approximately $3 billion in 2005 to $25 billion in 2015. Several countries have dedicated
innovation programs to support and develop RFID systems and related technologies: the
RFID initiative in Taiwan, Ubiquitous Japan and the NSF SBIR program in the USA.
The EU has recently advertised its Strategic Research Roadmap concerning the Internet of
Things, which first of all refers to the RFID technology before being extended to commu-
nicating devices as in M2M (Machine to Machine). In this roadmap, several application
domains have been identified:
