【 Weak current College 】 wireless LAN in the intelligent construction of widely

The core of intelligent building system integration, and system integration Foundation is the intelligent building communication networks. With computer technology and communication technology and the advent of the information society, forcing modern architecture concept had to be updated. In the information society, a modern building, in addition to telephone, fax, air conditioning, fire and security monitoring systems, all kinds of computer networks, such as integrated services digital network is indispensable.
Only with these basic communications facilities, new information technologies, such as electronic data interchange (EDI), electronic mail, video conferencing, video on demand, multimedia communication, it will be possible to enter the building. Makes it a truly intelligent building. As distributed intelligent building control system technology matures and application of universal, BAS will further diversify in control, transfer of the network will be more of a management information system, integrated, the more importance. On the other hand, due to the proliferation of people information needs, as well as computer technology Multimedia terminals and other advanced Terminal technology, a smart building intelligent bottleneck often lies in its communications network. It can be said that communications network technology level restricts the degree of intelligence for intelligent buildings.

To this end, the intelligent building communication networks design is a complete building intelligent engineering focus. With the communication and the rapid development of computer technology, intelligent building technology becoming more mature, intelligent building construction is in the ascendant. In building intelligent building, the building of the design phase, it is necessary to integrate into the design of the communication network.

Wireless LAN technology can save costly cables, avoiding the cable termination of non-reliability while meeting the computer within a certain range can replace the geographical location of need and is therefore an important future intelligent building technology platform. In recent years, wireless local area network products gradually maturing for wireless LAN products prices gradually declining, while at the same time, a wireless local area network has been able to combine with wide area networks to provide mobile Internet in the form of multimedia services. There is no doubt that wireless LAN will be its high-speed transmission capacity and flexibility in the intelligent construction play an important role.

(1) wireless network in the application of intelligent building

In today's wired network of offices, with the increase in the number of company employees, leading to an increase in the working position, but the Office space is limited, expand Office, and chairs would increase operating costs, and not the ideal solution. At the same time, the staff of the Office of the seats and sector adjustment would result in very big trouble, and sales and service support staff frequently out of the seat of idle caused a serious waste of company resources.

Similarly, the wireless network you can overcome these problems, take a look at an example: equipped with a wireless network, the Hewlett Packard Company in the mobile office environment makes the station is no longer the only Office locations, than ever before, the number of employees is increasing, but the number of office furniture had declined, because every day out of Office staff, and those employees who work in the company, as long as you find an empty place to work. Staff at the Office of any corner, can feel free to e-mail us, share documents and Internet browsing, greatly improving the working efficiency, while also reducing the total cost of ownership.

In common Gallery technology exhibition, exhibition such as General electronics, computer, the network needs of extremely high, and the wiring and will let the venue looks messy, use the wireless network that does not undermine the internal decoration of the venue, but in a short time to build the network environment for exhibitors on the Internet has facilitated, promoted the exhibition organizing Committee the level of services to help them build a better image.

(2) wireless network to function in the smart home

Today, the Internet in the world, with more than 80 million users, it has become the family pass information in an efficient manner. As the network speed gradually upgrading and Internet resources of gradually enriched, family based Internet messaging needs will continue to grow.

At present, more and more families and the public network, including multipoint connection for transmission of voice information for the General telephone line, Internet access and fax, as well as special phone line for entertainment and high speed data transmission cable connection.

Home electronic systems, electronic appliances and household electronic devices have become more intelligent, and have the computing and communication capacity, and this internal intelligence in these devices disconnected when it is unable to play a role.

These new trends enables people to share in the family PC, Internet access, telephone lines, peripherals and information produced strong demand. It is this kind of demand, promote the home networking market's rapid development. Home network adoption family PC interconnection with other equipment to provide the user with an information and resource sharing. With the family in more and more PCs, peripherals, and intelligent devices, when the network connection value-added, home users will face new challenges and opportunities. For example, users will have this demand: in house anywhere you can get information through the Internet; PC and share files between PC and share printers, scanners and other peripherals, regardless of their place within the family which place; control of electronic systems and equipment, for example, in housing, residential surroundings or away from residential areas, are able to turn on or turn off the lights in the House, water heaters, air conditioners, and home security systems; effective management of a communication channel, such as the telephone, fax and Internet access assigned phone line. These capabilities are needed in the home networking to connect different devices work together. However, to be truly effective, any home network must follow the following standards:

A, residential must not have extra wiring. Most families have not set up network, in housingWiring may cause network price promotion, hindering the development of the market.

B, wireless connections, you must have a valid immunity, especially for home growing emission RF noise of wireless devices and equipment.

C, the range of the wireless connection must be sufficient to cover the typical family houses, allowing the devices in the apartment and residential near any place to communicate between devices.

D, the network must have a high level of security, the prevention of illegal users of intrusion.

E, for users who do not understand the technology, the network must be easy to install, configure and use. Because most home users do not have to handle complex network installation and configuration issues.

F, at any time, in the House even far away from any place of residence, the network should be able to quickly access.

G, programmes of costs must be moderate, the price you want to make the most of the consumer is able to accept.

In short, users need to be able to connect to home electronics wireless network, the network you want to use the convenient, affordable, easy-to-access, capable of transmitting voice and data information. This article previously mentioned three wireless network, you can meet such a request, because they are not affected by the transmission line, telephone jack or outlet location restrictions, has a high degree of flexibility, avoid wiring difficulties, cable, expensive, require professional installation and debugging problems. The wireless home network for voice transmission and data transfer to meet the needs of users, so that users in the family can enjoy real roaming capabilities.

With the wireless network technology will continue to improve the future of wireless home network and telephone network (PSTN) and Ethernet, and other network work together. This will enable wireless network be connected home computers, information appliances, home security system's backbone network.
