Wi-Fi technology is a critical component of modern healthcare infrastructure, being integral for a variety of applications, from electronic health records and telemedicine to patient and visitor communications. This report considers Wi-Fi's operation on radio waves and its dependency on unlicensed RF spectrum, regulated in the UK by Ofcom.

This report provides an assessment of Wi-Fi performance metrics to explain how networks can support healthcare delivery across the NHS, considering the unique demands and complexities of each healthcare setting.

For an introduction to Wi-Fi and other wireless connectivity technologies see an introduction to wireless technologies in health.

This report provides guidance on the measurement, analysis, and management of Wi-Fi performance metrics.

These metrics are fundamental to the maintenance and improvement of Wi-Fi services and play a crucial role in healthcare delivery. Additionally, they must be recognised for their pivotal role in critical digital transformations.

These transformations include:

• the rollout of new electronic patient record (EPR) systems
• the adoption of electronic bed management
• asset tracking to enhance operational efficiencies in patient flows 
• implementation of wayfinding solutions
• strategies to reduce missed appointments
