Taiwan region based on ZigBee wireless sensor network deployment

The ultimate goal of communication technology development is nothing more than "everywhere" four words, in order to construct can transfer any information required for the environment at any time and any place, including Japan, South Korea and Taiwan region began to develop a "ubiquitous network (Ubiquitous Network)" plan I hope, through the combination of different kinds of communication technology, woven into a close communication network, more safety and convenience for people's daily life.

An important key in the program is the Sensor (Wireless) Networks (Wireless Sensor Network) architecture, and the current Taiwan region has been initially realized by ZigBee technology pan network vision.

Taiwan Information Industry Market Intelligence Center (MIC) director Zhan Wennan said: "the construction of ubiquitous network, will affect all aspects of people's daily life, food safety, medical care, home life, social service and circulation management, will also bring huge business opportunities." He pointed out that, including the Japanese government's U-Japen, the South Korean government's U-Korea and U-City (Samsung) group and other programs, the goal is to achieve ubiquitous network environment. Taiwan region also developed the "U-Taiwan" program, as a part of the Taiwan science and technology policy. The ubiquitous network, must include WLAN (Wi-Fi) WWAN, GSM, GPRS, 3G, DTV), WPAN (Bluetooth, ZigBee, UWB) and other communication technologies in different fields of mutual combination collocation, one of the key important is the architecture of wireless sensor network. It is understood that the wireless sensor network is the first in the United States of California Berkeley (UC Berkeley) a survey conducted by the U.S. Department of defense sponsorship program, researchers will be a microelectromechanical system (MEMS) micro sensor cloth manufacturing technology built in a specific range, so that the relevant information can be collected to the environment to do for military purposes; and the concept of application can have different effects on people's daily life, including security monitoring and management of the living environment, public places, all through the network architecture to achieve goals.

Institute of National Tsinghua University professor Wang Jinliang Department of electrical engineering and communication engineering is a wireless sensor network construction plan said: "the wireless sensor network needs related sensor and communication devices, must be in line with low cost, low power consumption and small volume, easy deployment, and must even have programmable, dynamic configuration characteristic." Therefore, one of the goals of the project is to use ZigBee technology as the backbone of the network connection.

The information industry and actively develop ZigBee application network multimedia research institute, is working with the Taichung Natural Science Museum, the Museum of about 6000 square meters in size to a part of the exhibition in the establishment of wireless sensor network based on ZigBee, and has already started in July this year the actual use, can provide tour guides, tour route planning and visitor location tracking function.

The advanced mobile technology center director Feng Minghui said: "we build in the museum in the ZigBee network, the configuration of the 155 ZigBee nodes (including Router and Beacons), the positioning accuracy can reach 91 ~ 97%." He then pointed out, and the museum's cooperation is the preliminary design of ZigBee wireless sensor network, the information industry is also in cooperation with the Taiwan area shopping malls, amusement parks and the community to discuss matters relating to.

According to market research firm In-Stat MDR, the global ZigBee market in 2004 to 2009, with an average of 200% compound annual growth rate (CAGR) expansion of its territory, in 2009 shipments will reach 150 million sets, the huge business opportunities. Currently available ZigBee chip manufacturers to Chipcon, Freescale Carle (Freescale), Ember, Atmel and other manufacturers based in Taiwan area only Shengda (UBEC) released ZigBee radio frequency (RF) chip, the pace is too slow. Taiwan Information Industry Research Institute of the multimedia network protocol stack is locked ZigBee (Protocol Stack) software development, will combine with the ZigBee chip supplier launched a full range of solutions, in a variety of household electronic equipment control, building lighting and energy monitoring, community safety protection, medical care and other applications for business opportunities.
