    • Adding new workstations or mobile medical equipment quickly and easily.
    • Supporting temporary setups for special events or emergencies.
    • Facilitating the integration of new medical devices and applications.

• Title: Ensuring Dependable Connectivity
• Content:
  • Overview of WLAN reliability improvements:
    • Advancements in WLAN technology (e.g., 802.11ax/Wi-Fi 6) for increased capacity and performance.
    • Redundant access points (APs) to minimize downtime.
    • Load balancing to distribute traffic and prevent congestion.
    • Quality of Service (QoS) mechanisms to prioritize critical traffic (e.g., voice, video).
    • Mesh networking for self-healing and extended coverage.

• Title: Mitigating Wireless Interference
• Content:
  • Define interference: Disruption of wireless communication caused by other signals.
  • Common sources in medical environments:
    • Other WLANs.
    • Medical devices (e.g., electrosurgical units, MRI machines).
    • Microwaves.
    • Building materials (e.g., metal, concrete).
  • Mitigation techniques:
    • Spectrum analysis to identify and avoid congested channels.
    • Proper AP placement to optimize signal coverage and minimize overlap.
    • Channel management and frequency coordination.
    • Use of directional antennas.
    • Shielding and filtering.
    • Regular site surveys.

• Title: Safeguarding Sensitive Patient Data
• Content:
  • Explain common WLAN threats:
    • Eavesdropping: Unauthorized interception of wireless communication.
    • Unauthorized access: Individuals or devices gaining access to the network without permission.
    • Data breaches: Exposure of confidential patient information.
    • Man-in-the-middle attacks.
    • Denial-of-service attacks.
  • Recommend basic security measures:
    • WPA3 encryption: The latest and most secure Wi-Fi encryption protocol.
    • Strong passwords and authentication.
    • Network segmentation: Separating different types of traffic (e.g., guest network, medical device network).
    • Role-Based Access Control (RBAC)
    • Firewalls and intrusion detection/prevention systems.
    • Regular security audits and updates.
    • Network Access Control (NAC): to authenticate and authorize devices before granting network access.

• Title: Understanding Wireless Communication
• Content:
  • Decibels, Gain, and Loss (LO1):
    • Define decibels (dB): A logarithmic unit used to express the relative strength of a signal.
    • Explain gain: Amplification of a signal, measured in dB (positive value).
    • Explain loss: Attenuation or weakening of a signal, measured in dB (negative value).
    • Explain how dB is used to calculate signal strength at different points in a wireless network.
  • Antennas (LO2):
    • Describe the function of antennas: Devices that transmit and receive radio waves.
    • Explain their role in wireless network performance:
      • Signal strength and coverage.
      • Directionality (omnidirectional, directional).
      • Antenna gain and its impact on signal range.
      • Types of antennas (e.g., dipole, Yagi, patch) and their applications.
