What is mobility in a healthcare setting?
Mobility is used to describe continuous network connectivity, providing the user with anytime, anywhere access to social media, clinical, or business application data. When Wi-Fi® client devices and the hospital network to which they connect properly support mobility, a wireless device can access the network while on the move anywhere in the building and sometimes outside of the building (e.g. walkways between buildings). To properly support mobility in hospitals, adherence to best practices in the design, installation, and management of the Wi-Fi network and devices is essential.
What is the impact of security mechanisms on mobility?
The healthcare industry adheres to another layer of security requirements prescribed by laws addressing privacy and a patient’s clinical information (e.g. HIPAA (Health Insurance Portability and Accountability Act, PCI (Payment Card Industry)). Protecting electronic health information is an essential business need for hospital administrators. Fortunately, Wi-Fi has strong encryption and authentication capabilities in the form of WPA2™ to assist IT managers in implementing security policies.The basic security principle in IEEE 802.11 is that each time a client connects to an AP it must complete the authentication process. The two main types of security used are WPA2-Personal and WPA2-Enterprise and each has a different impact on roaming behavior because WPA2-Enterprise requires more steps in the authentication process. When the Enterprise version of Wi-Fi Protected Access® 2 is used, the required authentication when roaming adds time to the authentication or re-authentication process. For mobile devices, this added time may impact real-time streaming client performance. For important clinical applications like telemetry, where mobility is a part of the clinical usage, the use of a fast roaming algorithm such as 802.11r is recommended. As an example, when high quality of service (QoS) applications such as VoIP are used on a properly implemented Wi-Fi network, the combination of WPA2-Enterprise and fast roaming techniques provide a secure and reliable connection. The Wi-Fi Alliance’s Voice-Enterprise certification incorporates these important capabilities and is a key enabler of a high-performing enterprise WLAN.
How does Passpoint support service provider branding and customer relationships?
Passpoint enabled mobile devices can choose networks based on a list of preferred (direct or partner) providers, specific services and/or the best performance characteristics. For service providers offering a managed experience, seamless authentication is a valuable element, and Passpoint networks also support deployments where a click-through screen is essential for acceptance of terms and conditions or branding.
