User needs

Nowadays, education informatization has become a consensus of education reform. As a key university that trains high-quality and high-level talents, Wenzhou Medical College has become an urgent task to form an advanced campus network to serve the school's teaching, scientific research and other applications. Today, when wireless LAN technology is mature, wireless network solutions can meet the special industry requirements of campus networks, and have easy scalability and free mobility unmatched by traditional networks. One of the best choices for campus network solutions. Due to the large scale of the school, which is composed of multiple colleges and many buildings, the school decided to use an advanced wireless network. It is not only economical and easy to install, but also requires little configuration and maintenance.

Technical solutions

Aiming at the construction of the wireless network of Wenzhou Medical College, a wireless deployment plan was finally designed for the school and the wireless network was constructed. The network diagram is as follows:

The wireless network implementation of Wenzhou Medical College uses NETGEAR's WG302 and WGE101 wireless products. The 108M WG302 is selected at the center of the wireless network, and then the 54M wireless AP WGE101 is installed at each base point on the campus. Central computer room) set up an omnidirectional outdoor antenna and an outdoor directional antenna. The omnidirectional antenna covers all teaching buildings and playgrounds on the campus; set the directional antenna on the experimental building to transmit the signal to the teaching building A; the directional antenna is also erected on the teaching building A to transmit the signal to the teaching building B; in the teaching building B An omnidirectional antenna can be installed on the lawn to cover the lawn. At the same time, it can also transmit signals to nearby buildings. In this way, as long as the students or teachers in the area covered by the wireless network can use the wireless network card to achieve the purpose of Internet access, they can easily and quickly access network resources, reflecting the freedom and advanced nature of contemporary information networks.

The AP equipment of this solution uses WG302 of Netgear of America, supports Super G â„¢ technology, and its transmission speed is up to 108Mbps. It can not only transmit ordinary data packets, but also transmit multimedia files such as video and audio to meet the bandwidth requirements of video teaching on campus. The introduction of the IEEE 802.11g standard is the most ideal choice for Wenzhou Medical College. The WG302 based on the IEEE 802.11g standard provides advanced security, super performance, complete and advanced functions, super strong signal coverage and rich management features , Fully meet the requirements of wireless LAN equipment for campus applications. In addition, the innovative WG302 can also support wireless bridge mode and wireless access point AP mode simultaneous artifacts, one machine and two uses, providing the best solution for users with a wide area such as Wenzhou Medical College to implement wireless LAN.

Each base point in the school uses the 54M wireless AP WGE101. WGE101 can easily allow a device with only an Ethernet interface such as a game console and a computer to easily access the wireless LAN. It provides maximum convenience for those devices with only Ethernet interface to access the wireless network. WGE101 supports Ad-Hoc networking, and can support multiple devices to access the wireless local area network at the same time through switches or hub devices.

Advantages of wireless network on campus:

· On the basis of fully considering the difference between campus and other places, the campus adopts a wireless network, and different standards can be adopted in terms of network security, cost, and distribution range. It does not require such high security performance, but the coverage area must be wide To cover some corners and old-fashioned buildings, wireless coverage is beyond the reach of wired power, which is a major advantage of wireless networks in campus applications. Secondly, most of the school ’s network users are mainly students. The application of wireless is more convenient and reasonable in price. At the same time, the structure of wireless network is much more convenient than wired. This is the product of wireless network used in any industry. Both have obvious advantages.

· The use of wireless network on campus can quickly establish a small or heavy campus network, and the investment is very small. If there is a campus network already built, wireless can increase the coverage of the network and make the network cover the rectification of the campus. The school needs to hold any temporary activities. The network requirement is the wireless coverage rate. This requirement can be easily achieved. The wireless network can be used to access network resources at any location

· Using wireless LAN technology, teachers and students can achieve fast and flexible access to all learning resources on the Internet, and all students can achieve access to wireless LAN. Use wireless LAN to connect to the school's intranet, download learning software, and retrieve extracurricular homework , Submit homework to teachers through the network, you can also use the wireless LAN to send e-mail, access to the school's online library catalog and other school resources and network applications.

Program features

The biggest feature of this solution is the use of the latest wireless LAN new standard-IEEE 802.11g wireless LAN solution, wireless plus wired LAN connection, provides a new network access mode and ubiquitous network connection, technically At the leading level.

Conclusion

In today's era, network technology has achieved global sharing of information resources, and more and more industries have realized networking. Medical education bears the important task of cultivating medical workers who remove pain and save lives, and information sharing is even more needed.
