Hospitals have unique networking requirements due to the critical nature of their operations and the sensitive data they handle. They rely heavily on digital tools and advanced medical equipment that require a robust, secure, and reliable network infrastructure. This includes electronic health records, clinical imaging systems, and remote patient monitoring, all of which depend on uninterrupted connectivity. Hospitals must ensure secure access control, protect patient data, and accommodate a wide range of devices and emerging technologies. The complex floor plans and signal-blocking features of hospital buildings also present challenges, requiring careful network design and optimisation. As such, hospitals demand specialised skills in wireless engineering and network architecture to meet their unique networking needs.

What You'll Learn
Security and access control
To ensure security, hospitals should conduct regular security audits and vulnerability assessments to identify and address potential risks. They should also implement redundancy in network components, such as access points, controllers, and network paths, to prevent downtime and ensure network availability. Hospital networks should be designed with scalability in mind to accommodate future growth and the increasing number of connected devices.
Wireless network design in hospitals is challenging due to signal-blocking features, radio-frequency interference from medical devices, and complex floor plans. To achieve total campus coverage, hospitals often require a higher density of access points than typical non-critical networks. Wireless engineers and architects must possess a unique skill set, including an understanding of RF and physics, to effectively design and manage hospital wireless networks.
Hospitals should also be mindful of emerging technologies and their bandwidth requirements when setting up Wi-Fi networks. This includes considering the bandwidth needs of mobile medical devices, staff communications, alert systems, and guest networks. By partnering with the right vendor, hospitals can overcome these challenges and establish a secure and reliable network capable of supporting critical functions.

Reliable and uninterrupted connectivity
To ensure reliable connectivity, hospitals should implement redundancy in network components, such as access points, controllers, and network paths, to prevent downtime and guarantee network availability. The network design should accommodate future growth and the increasing number of connected devices, ensuring scalability to meet evolving needs.
Hospitals also need to address signal-blocking features and medical devices that produce extensive radio-frequency interference (RFI). The complex floor plans of hospitals present a challenge for wireless signals to reach every area, requiring careful consideration of WAP distribution and density to achieve total campus coverage.
Additionally, hospitals should have a wireless team with the necessary skills and tools to manage and optimize the network. This includes understanding RF physics, utilizing analytics and NAC platforms, and staying up-to-date with IEEE standards and industry guidance. Regular operational maintenance is crucial to ensure the dynamic nature of the hospital environment does not impact network performance.
By following these practices, hospitals can achieve reliable and uninterrupted connectivity, which is vital to support the wide range of devices and applications that depend on stable Wi-Fi networks.

Wireless network design
When designing a hospital wireless network, it is crucial to consider current and future network needs. Technology evolves rapidly, and hospitals must be prepared to accommodate emerging technologies and an increasing number of connected devices. Wireless engineers and architects play a vital role in understanding RF and physics to ensure optimal network performance.
To ensure a robust and secure wireless network, hospitals should implement advanced access control protocols to restrict network access to authorized personnel and devices. This helps protect sensitive patient data and prevent unauthorized access. Regular security audits and vulnerability assessments are also necessary to identify and address potential risks.
Additionally, hospitals should consider the unique construction materials and work around lead walls in radiology departments. Understanding workflows and supporting jitter-prone communications, such as Voice-Over-WiFi, are equally important. A balance must be struck between providing sufficient access points and avoiding overly dense deployments that reduce network throughput.
A well-designed wireless network in a hospital setting can enhance patient care, improve operational efficiency, and enable seamless collaboration between medical professionals. It empowers healthcare providers with real-time data, remote monitoring capabilities, and efficient inventory management, ultimately improving patient outcomes.

Bandwidth requirements
Hospitals have unique networking requirements, and these are largely driven by the critical nature of their work. The health of hospital patients is, in some ways, tied to the health of the hospital's wireless network. A stable WiFi network is essential for many aspects of hospital operations, from inventory management and patient registration to staff coordination and communication.
Hospitals have a wide range of bandwidth requirements, from clinical imaging systems and electronic medical records to kitchen, laundry, HVAC, and patient entertainment systems. All of these systems require a reliable network connection to function properly. In addition, hospitals must also consider the bandwidth requirements of emerging technologies to avoid having to rip and replace their network infrastructure in the future.
The density and placement of access points are critical to ensuring adequate bandwidth throughout the hospital. Overly dense models can waste resources and reduce the effective throughput of the wireless network. On the other hand, too few access points or improper placement can result in dead zones, which are unacceptable in a healthcare setting.
To guarantee the necessary connectivity, hospitals often opt for a higher density of access points than non-critical networks. The standard WAP density for non-critical networks is approximately one access point per 3,000 square feet, but hospitals may require more to overcome signal-blocking features and medical devices that produce extensive radio-frequency interference (RFI).
In addition to density and placement, hospitals must also consider the bandwidth requirements of the various devices and applications running on their network. Voice-over-WiFi, for example, is prone to jitter and requires careful planning to ensure adequate bandwidth.
By ensuring sufficient bandwidth, hospitals can support the smooth operation of their critical systems and avoid interruptions that could negatively impact hospital operations.

Scalability and future-proofing
The number of connected devices in hospitals is increasing, and the network must be able to accommodate this growth. This includes not only medical devices and computers but also personal devices of patients and staff. A hospital network should be designed to support a large number of devices with varying lifespans and bandwidth requirements. For example, older devices may require 2.4 GHz radios, while newer devices may prefer 5 GHz.
To ensure scalability, hospitals should implement redundant network components such as access points, controllers, and network paths. This helps to prevent downtime and ensure network availability, which is critical in a healthcare setting. Hospitals should also consider the use of wireless networks to support mobility and total campus coverage. This includes physicians, clinicians, and nurses being reachable no matter where they are in the hospital, including elevators, stairwells, and basements.
Future-proofing a hospital network involves keeping an eye on emerging technologies and their bandwidth requirements. Technology changes rapidly, and hospitals must be prepared to integrate new devices and applications. This may include telemedicine, remote monitoring, and new medical equipment that relies on wireless connectivity. By considering the bandwidth and speed requirements of future technologies, hospitals can avoid a "rip-and-replace" scenario and ensure their network is future-proof.
In addition to scalability and future-proofing, it is essential to prioritize security and ease of use. Advanced access control protocols should be implemented to ensure only authorized personnel and devices can access sensitive information. Regular security audits and vulnerability assessments are also crucial to identify and address potential risks.
