just over $100 and opened the door for broad adoption across hospitals of all sizes and budgets.
Because the system is battery-powered and built on Bluetooth Low Energy (LE), it avoids the complexity of power-over-ethernet life under typical hospital workloads.
The role of Silicon Labs
Silicon Labs’ technology played a pivotal role in making Emanate Wireless’ vision possible. The BG22 Bluetooth SoC acts as an angle of arrival (AoA) receiver, listening to the tag via an antenna array to collect CTE packets and extract phase information for precise this data, running machine learning inference on Silicon Labs’ integrated AI accelerator. allowed Emanate Wireless to run models that could distinguish doorway crossings with extraordinary 99.9 per cent accuracy, even in the multipath and interference-rich environments typical of hospitals. Beyond hardware, Silicon Labs’ development tools accelerated the company’s progress, including Silicon Labs RAIL (Radio Abstraction Interface Layer), which provides an easily
customisable interface. This, coupled with SDK, made it possible for Emanate Wireless to avoid extensive customisation.

When assets are misplaced or staff
Transforming healthcare operations
that once relied on manual processes. For example, when a patient presses a nurse call button, the system can automatically log a nurse’s arrival when their badge crosses into the room, eliminating the need for manual acknowledgment and improving compliance reporting.
”
Staff can instantly locate critical equipment, reducing wasted time searching for devices and ensuring availability where it matters most. Asset utilisation improves, capital expenditures fall and patients receive faster care. Nurses gain back time to focus on
patients rather than paperwork, boosting both satisfaction and outcomes. Because RadioVision works with off-the- shelf Bluetooth tags and wearables, hospitals avoid vendor lock-in and can expand the system to smartphones, smart badges and ensures the system can scale across entire facilities, assisted living centers, or long-term care environments.
The promise of affordable, accurate RTLS extends far beyond hospitals. Assisted living facilities, long-term care providers and other healthcare settings all face similar challenges in asset and staff tracking. With the cost- move from a luxury for elite hospitals to a standard for the broader healthcare market. By solving one of the hardest problems in wireless, achieving reliable room-level accuracy indoors, Emanate Wireless and Silicon Labs have unlocked a new era of location-aware healthcare. Hospitals can and care quality, ensuring that staff, patients, and equipment are always in the right place at the right time.
