Difficulty: MediumNetwork Types and Topologies

A healthcare facility is deploying a patient monitoring system in an intensive care unit. Bedside telemetry sensors worn by patients wirelessly transmit real-time vital signs over a distance of approximately 2 meters (6 feet) to a localized receiver unit assigned to that specific patient bed. Which network type best categorizes this short-range communication setup?

  1. Personal Area Network (PAN)Answer
  2. B
    Local Area Network (LAN)
  3. C
    Metropolitan Area Network (MAN)
  4. D
    Wide Area Network (WAN)

Answer

Personal Area Network (PAN)
The Personal Area Network (PAN) classification specifically applies to short-range communications centered around an individual or single workstation, usually restricted to a coverage area of less than 10 meters (33 feet). Wearable sensors communicating directly with a bedside monitor fit this definition precisely.

Step-by-Step Solution

1
Analyze the physical range requirement in the scenario.
The communication distance is specified as approximately 2 meters (6 feet) centered around an individual patient's bedside.
Geographic network classifications are primarily categorized by operational scope and physical coverage distance.
2
Map the distance and device relationship to standard network classifications.
Connections operating within a short radius of up to 10 meters (33 feet) for personal or dedicated wearable devices fall under Personal Area Network (PAN) standards.
Technologies such as Bluetooth, Zigbee, or low-power wireless telemetry over very short distances constitute a PAN.
