Design And Implementation Of Wireless Network In Hospital

Our hospital is a large-scale three-level A-level comprehensive hospital integrating medical treatment,teaching,scientific research,health rehabilitation and outpatient first aid.The informatization construction of our hospital started in 2006,and experienced three stages in the upgrading of the past ten years: single user Island use,Department data sharing use,and hospital wide informatization application.The information application system is based on the computer network system,which is gradually mature and developed in the continuous improvement of the computer network system.It can be seen that the information application is extremely dependent on the computer network technology.Therefore,our hospital has been continuously optimizing the network and upgrading.In order to better build the "smart hospital",under the high attention of the hospital leaders,our hospital needs to keep pace with the times,build a medium-sized wireless network,provide infrastructure for mobile information-based medical care,and complement and back up with the existing wired network.Therefore,through the practical application of this work as the research direction of this paper.On the basis of the wireless network upgrading and transformation of our hospital,the existing network is studied in detail,and the business that is in use and ready to go online is classified and evaluated.According to the needs of our hospital,the upgrading scheme is made,and the project test is passed,finally the wireless network system is successfully constructed.This paper introduces the design scheme and implementation process of wireless network in our hospital,mainly including the analysis of the overall needs of the project,the planning and design before the implementation,the parameter configuration of the core switch,AC wireless controller and other equipment during the implementation of the project,and the acceptance test after the implementation.Here is my main work:(1)according to the actual use scenario and the business nature of the existing application software,the demand analysis of the SSID of the wireless network is proposed: planning multiple simple and easy to remember SSID names,designing the access rules of SSID,such as authentication rules,broadcast methods,authorization rules and authorization results,for the use of various types of access users,to ensure that users will not interfere with each other.(2)after the AP is installed,configure the core network equipment such as AC,connect directly through the console line,use the "Hyper Terminal" software to log in the equipment for initial configuration,and after the initial configuration,log in through the network for subsequent configuration.(3)joint debugging test stage of the system: first,control the wireless access point AP through the controller AC,and send out the wireless signal;then go to the wireless network coverage area to do a number of tests through the notebook and mobile devices,the test items include network connectivity test,wireless signal coverage and strength test,connectivity login test,program application test,etc.,when the test signal fails,set That is,rectification and commissioning,and ensure to meet the expected standards after retesting.The wireless network system of our hospital has passed the test and officially put into use.It has been in operation for half a year.It has wide wireless signal coverage,stable mobile roaming,and no delay in accessing the server.It basically solves the problems existing in the wired network,meets the business requirements of our hospital,and meets the purpose of transformation and implementation.
