Wireless network lays the foundation for traditional industry transformation
In the past few years, for the traditional industry, it is mainly considering information security, data storage, convenient management and other factors, and is accustomed to using wired network operation, but wired network connection has one of the biggest drawbacks, it will be people, equipment and equipment. The data communication between them is firmly locked in a specific time and space. In recent years, with the proliferation and popularity of various types of intelligent mobile terminal devices, people's online habits and behaviors are changing. More people are accustomed to mobile office and mobile learning, so they want to stay online anytime, anywhere. Today, mobileization is accelerating into traditional industries. From the selection of mobile networks, according to a new survey in 2014, up to 68% of respondents prefer Wi-Fi instead of other connections (4G). , 3G or wired).
According to data from the WiFi Alliance in 2014, China has become the world's largest market for Wi-Fi demand, with Wi-Fi penetration in China reaching 21.8%. "Water is invisible and invisible", in fact, this is the true state of Wi-Fi currently in our work and life, but also infiltrated into the traditional industries.
The campus network is "moving up"
With the introduction of the "Internet +" program of Premier Li Keqiang in 2015, the requirements of the traditional industries for the integration of informatization and Internet access are urgent and strong, which is particularly prominent in the education industry that is recognized as the "most traditional". As the most important source and position for the development of the national economy, the school's educational model and methods directly determine the effectiveness of knowledge penetration and economic conversion rate. At present, the continuous rapid growth of mobile intelligent terminals on campus poses new challenges to the access mode, access capability and access security of today's campus networks. It is urgent to require the campus network to rapidly evolve from the previous single wired access mode. The access architecture that integrates wired and wireless, keeps pace with the times, and comprehensively builds a “smart campus†in the era of mobile internet. “Smart Campus†needs to support ubiquitous online learning, integrated and innovative network research, transparent and efficient school governance, rich and colorful campus culture, and convenient and thoughtful campus life. From the specific implementation point of view, the connection environment, security, stability, high performance, high reliability of the Internet environment is the most crucial first step, so many colleges and universities will include wireless network construction as the primary task of school information development.
For example, China University of Political Science and Law, Renmin University of China and other key universities have upgraded the original wireless network in 2014, deploying the latest standard 802.11ac campus network, and providing the first to provide gigabit Wi-Fi access for teachers and students. Through the research and reference of the network upgrade effect of these well-known universities, as a higher vocational college, Dalian Vocational and Technical College has successfully deployed the first 802.11ac campus network in Northeast China, and also adopted the wireless network solution of Aruba Networks of the United States. The solution, through the deployment of Aruba "7200 wireless controller + 802.11ac high-performance wireless AP + AirWave network management system" core combination program, the wireless network covers a total of 560,000 square meters of two campuses, truly no dead ends There is no blind zone, and the whole network has the wireless roaming capability of the wireless terminal. It can not be disconnected and does not need to be re-authenticated, completely solves the phenomenon of false signals, and easily realizes unified monitoring and visibility of all controllers and APs in the wireless network environment. And management, reasonable allocation of traffic.
Aruba's user-based, time-based, location-based access control strategy intelligently differentiates access control policies and bandwidth based on user groups for the security access of different groups of teachers, students, and visitors. Flexible control and secure login. The head of the Modern Education Technology Center of Dalian Vocational and Technical College said that “Aruba Secure Access Solution provides high-intelligent access services for tens of thousands of teachers and students and a wide variety of wireless terminals in our school, meeting the secure access methods of wireless devices. Personalized security policy allocation, electronic proctoring, and high-security access to confidential departments provide a strong guarantee for schools in teaching, research management and services, making the school's wireless campus network application intelligent and unique. Leading mode. It is reported that a flexible and efficient wireless network has been deployed in the secondary general education industry of Beijing Normal University, which has been widely praised by teachers and students.
Medical mobileization "presentation"
In the various industries where WLAN technology is widely used, the medical field is considered to be one of the most suitable industries for applying wireless networks to improve office efficiency due to its mobility of medical work, mobile ward, mobile care, patient management, etc. Various wireless medical services are calling for support from all-wireless wireless technology.
In Xi'an Armed Police Hospital, as the workload and cumbersomeness of ward management increases, the response time to patients' conditions is higher than the original requirements. These requirements make the original network system and system unable to guarantee a smooth and undelayed ward. Management, these problems once plagued the staff. Now, in any place covered by the wireless LAN of Xi'an Armed Police Hospital, the medical staff can check the basic information and condition of the patient in real time through the handheld PDA. The PDA can collect and record the patient's body temperature, pulse, blood pressure, etc. in real time through the PDA. Various indicators are delivered to the server in the background in real time. Medical staff can also perform medical check-ups, audits, and executions through the PDA. When performing medical orders, record the execution time of the doctor's orders, execute nurses, etc., and provide valid data for future medical records. All of this is mainly due to the combination of Aruba's advanced wireless network technology and hospital HIS system, which greatly reduces the waiting time for patients to treat, and also greatly enhances the hospital's core competitiveness.
In modern hospitals, in addition to mobile rounds, mobile care has also broken the traditional work mode of nurses: mobile, bar code, and sharing of drugs, drugs, and treatments. The advantage of doing so is to ensure accurate information and safe medication. Improve the efficiency of nurses. The application of Aruba's mobile security network solution has greatly improved the real-time and effectiveness of medical information in Xi'an Armed Police Hospital. Combined with bar code technology and terminal scanning technology, it has improved the efficiency of medical staff, reduced errors and improved patient satisfaction. .
However, in addition to improving work efficiency and business level, patient privacy, medical information confidentiality and other needs are also issues that the medical industry must pay attention to. This requires a unique role for each health worker and a network security policy control based on the role of the user. This is a deep feeling for the doctors and patients of Peking University International Hospital. At Peking University International Hospital, wireless users are differentiated into a variety of roles, including: ordinary visitors, VIP patients, medical staff, office workers, and IT administrators. Visitors and VIP patients are completely banned from accessing any resources on the intranet through Layer 2 isolation. Medical staff use independent authority to allow access to medical servers such as HIS, PACAS, and electronic medical record systems. Office staff can access the EMAIL server, etc., but access to the medical server is prohibited. IT has the highest level of access to all network resources. Among them, the ordinary visitor obtains the online verification code through the CPPM self-registration method, and the validity period is 4 hours; the VIP patient is created by the ward management personnel to access the Internet, and the administrator of each ward department can only manage the VIP account created by himself; And medical staff access the Internet through their own AD domain account.
The technical staff of Peking University International Hospital Information Center said: "Aruba Secure Access Solution provides high-intelligent access services for a wide variety of wireless terminals such as doctors, visitors, inpatients, mobile ward rounds, etc., to meet the security of wireless devices. Different requirements such as access mode and personalized security policy allocation.†Similar to Peking University International Hospital, Xi'an Armed Police Hospital also realizes the security isolation between internal and external networks through the state protection wall function provided by Aruba mobile controller. The medical staff can only access the intranet server by using the medical terminal, and the external network user can only access the external network resources through wireless, and limit the bandwidth.
