Medical dedicated data network
Background of the plan
Wireless data intranets have been developed with the promotion of wireless data applications such as electronic medical records, mobile ward rounds, and bedside care. Mobile ward rounds and bedside care are core clinical businesses that require high stability, reliability, and security of wireless networks. The bedside nursing of nurses mainly uses PDA, which requires zero wireless signal roaming, zero channel switching, and zero packet loss within the ward area. When doctors perform mobile rounds, they need to access PACS images, which have certain bandwidth requirements. It is necessary to ensure that the download of PACS images can be completed within 3-5 seconds. In order to meet the bandwidth requirements of mobile rounds, it is generally recommended to use a wireless network that supports the 802.11ac protocol for the wireless data intranet.
Product advantages
Currently, major hospitals have launched mobile healthcare related businesses, and the development of hospital informatization is also in a transitional stage. Therefore, it is planned to carry out some applications based on wireless networks in the entire hospital's medical business area, providing reliable solutions for the comprehensive upgrade of the hospital's wireless network. In the process of wireless network scheme design, we can input the 2.4G+5GHz signal from an independent medical dedicated wireless data network base station into the medical dedicated wireless network platform system, so that two non-interference channels can work independently or collaboratively.
When mobile terminals are moving in the same medical dedicated wireless data network, they will always maintain good connection with the same channel, maintain high bandwidth and low latency during movement, and avoid various problems caused by switching and interference when mobile terminals are in the "plug-in AP" or "intelligent sub unit AP" mode, At the same time, the working channels of the 2.4G frequency band of the sub base stations on the upper and lower floors are set to 1, 5, 9, 13, and 4 channels with a 20MHz bandwidth, and the working channels at 5GHz are set to 42, 58, 155, and 3 channels with an 80MHz bandwidth, ensuring that the channels on the same floor do not overlap and there is no frequency interference between the upper and lower floors to avoid channel interference issues.
When a mobile terminal is used for roaming in a medical dedicated wireless network system, it will always be associated with the same subsystem and maintain good connectivity. During the movement process, it will always maintain good bandwidth stability and low communication delay, without any problems caused by jumping and switching between base stations.
There are four main types of mobile medical services planned or implemented by hospitals based on wireless data networks: doctor mobile ward rounds, nurse mobile nursing, outpatient infusion management, and mobile electrocardiogram monitoring. The use of mobile nursing and mobile electrocardiogram monitoring by nurses is mainly limited to undergraduate rooms and within the ward, with few cases of cross ward use. However, there is a high demand for mobile roaming within the ward; The mobile terminal used for doctors' mobile ward rounds may cross wards, and different SSIDs need to be set for different applications.
