Which characteristics describe WLAN requirements in a hospital that make it a strong training ground for WLAN technology?

• A. 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.
• B. High density on every AP with no security requirements.
• C. Only one AP per floor with unlimited users.
• D. Wireless printers and guest access are the main use.

Answer: (A)

In hospitals, the WLAN is a strong training ground because it combines mobility, security, and the way healthcare apps behave. Clinicians move quickly through rooms and halls, so the network must handle seamless roaming as devices switch between access points without interrupting ongoing tasks. That pushes you to design for fast, reliable handoffs, smart AP placement, and effective interference management.

Security is non-negotiable in healthcare. Limiting how many users can connect to an AP and enforcing strong authentication protects patient data and meets regulatory requirements. This creates realistic constraints you must plan for, teaching you how to balance secure access with available capacity and coverage.

Many hospital applications are inherently connection-oriented, meaning they rely on stable, ongoing connections to servers and services (electronic medical records, imaging systems, bedside monitoring and control). This drives the need for predictable latency, low jitter, and appropriate QoS to prioritize critical clinical traffic over nonessential data.

The other choices don’t capture these realities. An environment with no security requirements or extremely high AP density doesn’t reflect healthcare needs. A setup with only one AP per floor and unlimited users ignores mobility and security requirements. And making wireless printers and guest access the main use overlooks the essential clinical applications and secure, reliable connectivity that hospitals demand.
