Software-defined real-time location intelligence
SEAgnal®: a Scalable, Efficient, and Accurate software-defined location technology that brings reliable, consistent, and scalable high-precision spatial intelligence to Bluetooth Low Energy radios— achieving what was previously impossible with standard wireless devices.
WHAT IS SEAgnal?
SEAgnal® is IOSEA’s patented, software-defined location-sensing technology that fuses advanced digital signal processing, RF circuitry and antenna modeling, and system-level algorithms into a dynamic, adaptive model for wireless location finding.
This fusion-based approach continuously interprets both the hardware behavior of transceivers and the signal interactions within their surroundings, allowing the system to dynamically adjust its models and maintain accuracy even as conditions change.
Rather than chasing extreme precision alone, SEAgnal® focuses on delivering reliable and consistent accuracy to wireless systems—especially to technologies like Bluetooth Low Energy (BLE), where unpredictable multipath and interference have long limited performance.
Operating across both connection and connectionless modes, SEAgnal® achieves update rates of up to 150 Hz, enabling smooth, real-time tracking of moving assets.
SEAgnal®’s frequency-agnostic architecture, optimized through direct PHY-layer integration with our strategic leading silicon partner Renesas, enables performance levels that rival specialized systems.
SEAgnal® redefines what’s achievable with low-cost radio platforms by providing a Scalable, Efficient and Accurate (SEA in SEAgnal®) intelligent spatial platform that brings a new level of reliability and efficiency to standard, low-cost radios—transforming them into dependable sources of spatial awareness for industrial, retail, automotive, and enterprise applications.
HOW SEAgnal WORKS
SEAgnal® is built on IOSEA’s proprietary digital signal-processing framework that unifies radio-frequency (RF) and antenna modeling with real-time positioning algorithms. At its core, SEAgnal® performs joint estimation of range and angle between transceivers through advanced digital signal processing (DSP) functions, estimation algorithms and hardware-assisted modeling.
This dual-domain approach that combines signal behavior in both the radiating and non-radiating components of a device, provides an unprecedented understanding of how every signal interacts with its environment.
This holistic modeling allows SEAgnal® to leverage the actual implemented hardware geometry and spatial configuration of the deployed devices, enabling a true end-to-end representation of the radio system. The result is a versatile and adaptive solution capable of maintaining reliable accuracy even across diverse environments and form factors.
The technology leverages patented methods including autonomous deployment and self-localization of stationary transceivers, and device-model-based estimation that enables each transceiver to serve as both a signal source and as an intelligent observer. These methods form the foundation for a self-organizing network that can discover, calibrate, and optimize itself in the field.
SCALABILITY
Scale through Flexibility
SEAgnal technology is designed and built to scale. Seeking customers that have the best products with high growth potential, IOSEA recognizes the importance of designing solutions that fully scale with the clients’ expectations and ecosystem. IOSEA technology is robust; it is proven beyond a lab environment, and fully tests solutions beyond normal situations and in varying environments.
EFFICIENCY
Efficiency in Customization
IOSEA's Proprietary Device Model (PDM) ensures optimal hardware and software performance that fits any devices' and applications' requirements. This process can satisfy the most challenging requirements and results in optimal size, weight, and power (SWAP) designs with high cost-efficiency.
ACCURACY
Superior Accuracy
IOSEA's solutions can be integrated with stationary or mobile devices. Each device can support multiple other devices, regardless of the distance that separates them, and is able to locate them within centimeter accuracy. Based on system configuration and environment, SEAgnal technology gives customers the most cost-efficient and accurate solution for their devices and/or applications.
