Represents the next generation of wireless LAN environment, infrastructure, education

The new 802.11n wireless standard that will last maryeon. Existing wireless standards, the 5 times higher than rates peaked, opens the era of fast Ethernet LAN in terms of times and received considerable attention. Comparable to wired broadband network infrastructure that supports wireless speeds by now more than ever the importance of wireless is growing. The company, as well as internal dimensions in recent WLAN enabled smartphones are once again attracting attention. In this situation, the next-generation wireless infrastructure, education seems to play an important role in the environment. As large campus LAN can be rolling in, even just within each building, a new educational experiment, even WLAN is already there. Recent trends in regard to the relevant article 24 sonyoungung Korea sseurikom bonaewa will appear here.




Today, throughout our lives that affect IT has brought tremendous change in the educational environment. IT skills with the written description was dependent on the traditional educational environment, teacher-centered learning experiences that provide a variety of student-centered educational environment will change, as well as serve as teachers and educators are helping to perform more effectively.



The institution of innovative IT solutions that introduce more representative of the whole runner is inclusion of a wireless network solution. Teachers of various learning experiences that can accommodate and wireless (WiFi) technology, except to discuss the current education infrastructure is not.



Most educational institutions in over 10 years of wireless LAN solutions to manage individual devices have been introduced. This easy to build a wireless LAN, but initially the long login time, frequent connection dropouts roaming, wireless connectivity problems, complex radio frequency (RF) due to administrative issues such as expected levels of schools to effectively use wireless services did not.



The last few years re-education institutions and their existing wireless infrastructure, introducing more advanced technology, the wireless network that is in a hurry. The main characteristics of these next-generation wireless network technology are as follows.



The main features of next-generation wireless network technology



First, the most differentiated features centralized configuration and control is a way. To operate each device separately, varied and complex features an access point (AP) Unlike the existing technologies in the implementation of next-generation wireless networks that provide only basic features so-called 'Dumb (Dumb)' AP and the wireless configuration and operations consists of a wireless controller.



This dumb the AP configuration and control is centralized and easier for settings and reprogrammed less risk of hacking for enforcement shall have the advantage. The pawn of the antenna and a simple transceiver for each wireless AP's and integrates hardware encryption can be installed anywhere easily.



The second features a mesh network (Mesh Network) is supported. Provide wireless services in a limited way, unlike the existing mesh network, which was free laptop or tablet PC, a variety of wireless devices can be used anywhere on campus so you can extend the wireless network service area. And wireless services in the area that you focused on a particular AP is the AP near the right of navigation, and give the necessary capacity secured. Through such a mesh network for wide area network connection, you can extend the boundaries of next generation wireless solutions due to physical constraints of the classroom gives haesohae.



The next-generation wireless network environment, the teachers through a PDA utilizing a variety of real-time communications to make it easier to monitor student activities and education to help ensure the safety of the environment. Therefore, school policies and teaching methods within a more diverse and rich learning activities can be tried. The next-generation wireless networks, IP-CCTV and efficient way to correlate the level of security can improve the school.



These next-generation wireless environment, the real-time communications, security and surveillance systems in relation to the theft, vandalism, and reduce the learning environment will contribute to improving physical security. In terms of network security with the latest wireless switch with centralized management and strict access control is guaranteed. For example, student data, curriculum, educational plans and other information that is accessible only to teachers and parents and students about the specific data that can limit access.



Finally, a teacher in a wireless environment, without having to use a dedicated device, utilizing a variety of wireless devices present data, results assessment, student information, instant messaging, e-mail quickly and easily type and send a free can efficiently handle administrative tasks can.



Considerations for introduction of next-generation wireless solutions



To provide the above benefits, but it introduces the next generation wireless solutions to educational institutions at the technical review will consider the following.



Network technologies for the sustainability of the item being considered is a top priority. Therefore, rather than ownership of specific companies or individuals to enable everyone to take advantage of publicly available open standard is better. IEEE 802.11a/b/g or most recently approved the use of open standards such as 802.11n based on the need for network expansion and introduction of new technology is easy to drive.



In addition to open standard for wireless networks which do consider. First introduced in the planning phase the following questions need to throw first. △ build a wireless network you have to do that? △ applications over a wireless network which will provide? △ bandwidth, capacity, security, service quality, reach, and the need to refine specifications regarding what?



Prior to the introduction of AP to the wireless network to cover areas such as the number of AP needed to determine the field of education with the help of network professionals to conduct accurate field investigation is desirable. The same survey of the communication radius of each AP and channel assignments, signal strength, interference and the presence of factors that will help identify, determine.



Preliminary research about the needs of the user the opportunity to discuss in detail because it is collected through this network of vendors based on best practices to plan network will be more appropriate.



The variety was introduced recently in PoE (Power over Ethernet) support the AP away from the webcam installed electrical outlet can be easily moved as needed, and can further enhance the flexibility of wireless LAN gives building. During the field survey for the installation and management costs with a closer review of the monetary benefits due to the PoE equipment goes, so too can determine in advance whether the check is introduced.



Finally, at the scene will affect transmission of AP or degrade the performance of wireless networks that must be considered for the elements should be included. These interfering factors in the elevator shaft and metal structures such as buildings, walls and doors and metal Material configuration, and the RF frequency variations, such as telephones or microwave use and other devices can emit radio waves. The same way through the field to conduct an investigation to identify the elements of these elements does not affect the AP to decide the installation location.



In-depth site surveys and network with the help of vendors to properly utilize the wireless network infrastructure provided by the school cost-effectiveness and reliability
