PHYTunes Technology

A High-Performance, Low-Latency Wi-Fi Solution with Seamless Roaming: How It Works

PHYTunes provides innovative Wi-Fi solutions using a cellular-like architecture, eliminating latency associated with roaming handovers for a seamless mobile performance. Its patented Saturn Wi-Fi uses in-building wiring to deliver consistent Wi-Fi 7 signals for optimal indoor coverage.

This transforms mobile device performance in manufacturing, hospitals, warehouses, and hospitality, enabling real-time, high-throughput applications such as physical AI (robotics) and other manufacturing 4.0 applications.

In legacy Wi-Fi solutions devices are attached to a single access point at a time.  In the figure below it shows how, as a device moves across the building, it must detach from the first AP and then reattach to the next AP.  This is called handover and introduces latency.  The roaming handover can be very disruptive to applications.  Many of the humanoid robotics applications that we have encountered require less than 10ms latency and legacy APs can average over 100ms due to this issue.  The legacy deployments are also complicated by the need for frequency planning which can drive deployment costs and ongoing operational costs.

The PHYTunes solution has a cellular like architecture with a Headend (Saturn) and RF Nodes. The RF Nodes are in sync to provide a Single Frequency Network throughout the area in which there is no notion of roaming for the moving device.  It is the same MAC address throughout.  These means that there is no disconnection, no latency from roaming and no frequency planning required.
