How wireless LANs can enhance the clinical environment

Area of Science:

• Healthcare Technology
• Network Infrastructure
• Wireless Communication

Background:

• Wireless Local Area Networks (WLANs) offer improved access to health information systems, potentially increasing clinician productivity and patient care.
• However, WLANs present challenges in reliability and security, necessitating careful consideration for healthcare environments.

Purpose of the Study:

• To evaluate the suitability of WLANs in healthcare settings.
• To highlight the limitations of WLANs for critical applications and compare them with protected frequency bands.
• To emphasize the importance of security and reliability in wireless network planning and deployment for healthcare.

Main Methods:

• Comparative analysis of WLAN (802.11) and Wireless Medical Telemetry Service (WMTS) frequency bands.
• Discussion of security vulnerabilities associated with WLAN access points in healthcare.
• Consideration of power management challenges for mobile electronic devices.

Main Results:

• WMTS offers a protected frequency range (608-614 MHz, 1395-1400 MHz, 1429-1432 MHz) established by the FCC, reducing interference issues compared to 802.11.
• WLAN security is a significant concern, akin to public network access.
• Standard WLANs may lack the bandwidth for large medical files and are intended to augment, not replace, wired infrastructure.

Conclusions:

• WLANs are valuable additions to healthcare IT but are not a complete solution.
• Critical applications requiring guaranteed reliability and protection should utilize WMTS.
• Thorough planning, focusing on security and reliability, is essential for successful wireless network implementation in healthcare.
