hospital wireless coverage solution -ag贵宾会

with clinical informationization, hospitals are gradually realizing paperless, filmless and wireless. with the continuous maturity and popularization of wireless local area network technology, the application of wireless local area network in the medical industry worldwide has become a trend . as a supplement to the wired lan of the hospital, the wireless lan effectively overcomes the disadvantages of the wired network, using tablet wireless computers and mobile trolleys to collect vital signs data, query and input medical care data, doctor rounds, bedside care, and call communication anytime and anywhere. , patient identification code recognition, etc., give full play to the effectiveness of the medical information system and highlight the technical advantages of digital hospitals. at the same time, perfect wireless coverage can also improve patients' satisfaction with hospital services.

demand analysis

1. it needs to meet the wireless coverage of all areas, such as registration office, outpatient department and inpatient department, etc.

2. the mobility of people is large, and the wireless terminal needs to automatically switch the access point during the movement of the wireless terminal, and the business is continuous, ie wireless roaming

3. the terminals are unevenly distributed and need to meet automatic load balancing to ensure the effect of wireless network use

4. the wireless network is mainly used for the internal office of doctors and the internet for patients. the ap needs to support multiple ssids, and different ssids have different network permissions

5. there are high requirements for wireless security, especially office networks, which require identity authentication to restrict illegal terminal access, such as mac address authentication

6. the appearance of the ap should be beautiful and generous, and it needs to support poe power supply to meet the requirements of fire protection and wiring

installation and deployment

the general environment of the hospital registration office is relatively open and there are few obstructions. the ceiling-mounted ap covers a diameter of 20-30 meters in an open environment. the number of use can be determined according to the scale, and the distribution points are evenly distributed, as shown in the following figure:

program features

high availability: ap uses professional antennas, and the transmit power is linearly adjustable. the ap transmit power can be adjusted reasonably according to the actual environment to meet the coverage requirements of different areas.

flexible roaming: fit ap wireless deployment architecture can set different aps to transmit the same ssid. when wireless terminals move between different aps in the same vlan, they can quickly switch between different aps to achieve cross-ap layer 2 fast roaming.

high reliability: the fit ap solution is adopted to support load balancing. ac can dynamically adjust the uniform distribution of users among different aps to prevent individual aps from being overloaded.

high scalability: it supports multiple user access authentication methods such as mac authentication and portal authentication, and can be combined with an external portal server and authentication server to achieve sms authentication, wechat authentication and other authentication methods.

easy to deploy: tp-link ceiling-mounted ap is adopted, which is beautiful and generous, supports 802.3af standard poe network cable power supply, and simple construction.

ease of management: ftt aps are uniformly managed by the wireless controller ac, which automatically discovers and manages the aps in a unified manner, and can view the operating status of the aps in real time, which is convenient for network management and maintenance.
