Which factor helps ensure hospital WLAN supports reliable medical applications during a site survey?

• A. Roaming across large distances only.
• B. A high density of users on every AP.
• C. Roaming across large distances, a limited number of users on an AP due to mandated security, and medical applications that are often connection-oriented between the client and server.
• D. No roaming and no security.

Answer: (C)

Reliability for hospital WLANs supporting medical applications hinges on keeping connections stable as people move, ensuring there’s enough capacity per access point to prevent contention, and supporting sessions that stay connected between client and server. Roaming across large distances matters because clinicians move through different areas of the building; if the handoff between APs is slow or disruptive, a patient-monitoring stream or real-time data feed can drop or stall. A site survey should verify that roaming can be done quickly and securely, often using features that speed up handoffs and help devices attach to the right AP without interruption. Having a limited number of users per AP helps keep airtime available for critical tasks and reduces latency and jitter caused by too many devices contending for the same wireless medium. In hospital settings, security requirements also constrain how many devices an AP should serve and how access is authenticated, which helps maintain predictable performance for sensitive medical data. Medical applications are frequently connection-oriented, meaning they rely on persistent, reliably delivered data streams between the device and the server. This makes consistent coverage, low drop rates, and solid QoS essential. If roaming is poor, or if an AP is overcrowded or left unsecured, those persistent connections can fail or become unpredictable, which is unacceptable for medical use. The combination of seamless roaming, controlled AP load due to security and performance needs, and the nature of medical applications that require stable, ongoing connections is what best ensures reliability during a site survey.
