Description

Campus network library radio network device

Technical field

This utility model relates to wireless aps research design field, particularly relates to a kind of campus network library radio network device.

Background technology

AP is exactly the HUB in conventional wired networks, equipment the most frequently used when being also to set up micro radio LAN, AP is equivalent to one and connects wired network and the bridge of wireless network, and its Main Function is each wireless network clients to be connected together, then by wireless network access network based on ethernet.

Most wireless aps all supports the functions such as multiple access, data encryption, multi tate transmission, some products more provide perfect wireless network management function, for family, the such little scope WLAN of office, the general wireless access only needing a wireless aps can realize all computers.

The indoor coverage areas of AP is usually 30m～100m, the AP product of many manufacturers can interconnect, to increase WLAN area coverage, also just because of the coverage of each AP has certain restriction, as mobile phone can roam between the base stations, wireless lan client can also roam between the aps.

Wireless aps, i.e. Access Point, namely WAP, is exactly the wireless exchange board in wireless network in simple terms, and it is the access point that mobile phone users enters cable network, it is mainly used in home broadband, Intranet deployment etc., wireless coverage distance is tens meters of extremely rice up to a hundred, and major technique is 802.11X series, and general wireless aps is also with access point client mode, that is wireless link can be carried out between AP, such that it is able to expand the coverage of wireless network；Simple type AP, owing to having lacked routing function, is equivalent to wireless exchange board, is only the function providing a wireless signal transmission.Its operation principle is to be sent by twisted-pair feeder by network signal, compiling through wireless aps, convert the electrical signal to send out for radio signals, form the covering of wireless network, according to different power, level of network coverage is also different, and the largest coverage distance of general wireless aps is up to 400 meters；Extended pattern AP is exactly the wireless router that we often say, wireless router, as the term suggests being exactly the router with wireless coverage function, it is mainly used in user's online and wireless coverage, pass through routing function, the Internet in family wireless network can be realized and connect shared, also the wireless sharing that can realize ADSL and partial wideband accesses, it is worth mentioning that, by wireless router, wireless and wired connection terminal can be all assigned to a subnet so that the various equipment in subnet can exchange data easily.

Continuous fast development along with mobile Internet, mobile Internet industry has become communication and the new trend of Internet industry development, operator has begun to by implementing wireless city strategy, actively seize the commanding elevation of mobile Internet, wireless city refers to that operator utilizes the multiple wireless access technologys such as 2G/3G/WIFI to provide the user whenever and wherever possible with the wireless network access services needed, and by polymerization various information information and application, provide the user safety, convenient, fast, efficient wireless network and abundant application service, when setting up city wireless network, need to use substantial amounts of wireless aps.

Progress and development along with science and technology, Construction of Campus Network gradually net wireless network covers transfer, facilitate academics and students to impart knowledge to students and learn, but school web user of service is such as student, there is the movement of regularity, the people such as sometimes library is more, wireless network is now used more to block up, in-convenience in use, when number of users is less, then it is easily caused waste of radio resources.

In sum, present inventor in realizing the embodiment of the present application during utility model technical scheme, finds that above-mentioned technology at least exists following technical problem:

In the prior art, existing campus library wireless network existence design is unreasonable, it is impossible to carries out Reasonable adjustment according to number of users, causes network congestion, or the technical problem of network resources waste.
