Challenge

As the wireless local area network (WLAN) technologies are increasingly mature and hospitals are on their way to IT-based development, use of WLAN has become a trend for hospitals.

Requirement analysis:

• Medical data needs to be strictly protected, and patient data cannot be stolen.
• The wireless network system may interfere with medical devices and have radiation that affects people's health.
• A stable network system is a basic guarantee for normal service operations of hospitals.
• The network must have a very low latency.

Solution Overview

The Huawei Mobile Healthcare Solution enables wireless access from laptops, personal digital assistants (PDAs), pads, wireless illness trackers, and other devices to the wireless network to support medical staff's activities, such as wireless ward round, assets management, personnel tracking, and online inquiry. With this wireless network, hospitals break space boundaries and can provide ubiquitous medical services for patients, thus improving the work efficiency of medical staff.

Benefits

• Ubiquitous: The solution provides coverage of an entire hospital, supports automatic channel, rate, and power adjustments, and enables multiple types of devices to access the network.
• Green: The professional test results show that the wireless signals have no interference in medical devices and no impact on human health.
• Secure: The solution supports mainstream authentication and encryption methods, such as the Wi-Fi Protected Access (WPA), WPA 2, and WLAN Authentication and Privacy Infrastructure (WAPI). It also supports wireless intrusion detection. Users are authenticated using Portal and 802.1x technologies to ensure Intranet security.
• High-bandwidth: The solution supports the 802.11n protocol and dual-frequency bands. The wireless access bandwidth reaches up to 300 Mbps. The solution also supports wireless roaming and multiple wireless quality of service (QoS) protocols like Wi-Fi Multimedia (WMM) to ensure service quality.
• Easy to deploy: The solution supports plug-and-play (PnP), automatic upgrade, and automatic channel selection for access points (APs), dynamic adjustments of equipment rate and power, and load balancing
