ZaiNar
ZaiNar enables precise indoor/outdoor positioning using existing radio networks.
ZaiNar provides real-time sub-meter positioning and location intelligence using patented phase-based signal processing and sub-nanosecond time synchronization on existing radio infrastructure. The system achieves sub-10cm accuracy indoors, outdoors, and through walls without GPS, operating system permissions, or device manufacturer cooperation. It serves enterprises and carriers across healthcare, construction, smart cities, and industrial sectors, with over $450M in contracts and deployments on multiple continents.
Problem solved
Organizations lack precise indoor positioning and real-time asset tracking, forcing staff to spend 20-30% of time searching for equipment and limiting hazard zone safety in industrial environments.
Target customer
Telecom carriers, enterprise operations, healthcare systems, construction companies, and smart city municipalities requiring sub-meter real-time location tracking at scale.

Competitors
Xona Space Systems
Building commercial positioning services using LEO satellite constellations; raised $170M as of March 2026.
TrustPoint
Alternative PNT service using low Earth orbit satellites rather than existing terrestrial infrastructure.
Starlink (SpaceX)
Researchers have identified potential for Starlink satellites to deliver PNT services from LEO, though not purpose-built.
Why this matters: ZaiNar represents a paradigm shift in positioning technology by moving precision location from a handset/device function to a network function, enabling sub-10cm accuracy on existing infrastructure without GPS or device cooperation. With $118M in funding from top-tier investors (SoftBank, Jerry Yang, Steve Jurvetson, Tom Gruber) and $450M+ in enterprise contracts, ZaiNar is positioned to disrupt GPS-dependent markets and establish a new standard for indoor/outdoor positioning across telecom, healthcare, construction, and industrial sectors.
Best for: Telecom carriers and enterprises needing indoor/outdoor sub-meter positioning without GPS, and organizations seeking real-time asset tracking in healthcare, construction, and industrial operations.
Use cases
Healthcare Equipment Tracking
Clinical teams use ZaiNar to locate and track medical devices in real time, eliminating the 20-30% of staff time typically spent searching for equipment. The system provides sub-10cm accuracy to quickly identify device locations across hospitals and medical facilities.
Construction Safety and Progress Monitoring
Construction crews use the platform to track heavy equipment in real time, automatically establishing dynamic safety zones and preventing worker hazards. The system enables live progress monitoring and equipment accountability without GPS or device modifications.
Smart City Infrastructure Management
Municipal and city operations use ZaiNar for precise tracking of assets and resources across urban environments, both indoors and outdoors. Sub-meter accuracy enables efficient fleet management and intelligent urban resource allocation.
Industrial IoT and Asset Tracking
Enterprises deploy the system to track robots, vehicles, and IoT devices with zero additional battery drain on tracked assets. The network-based positioning function operates transparently without requiring device-level changes or manufacturer cooperation.
Alternatives
GPS/GNSS Systems
GPS lacks indoor accuracy and requires clear sky view; ZaiNar delivers sub-10cm precision indoors, outdoors, and through walls using existing radio infrastructure.
Ultra-Wideband (UWB)
UWB requires device hardware modifications and shorter range; ZaiNar operates on existing radio signals with 1.5km+ read range and no device changes.
Cellular-based Positioning (A-GPS/E-911)
Traditional cellular positioning lacks sub-meter accuracy and depends on GPS or extensive infrastructure investment; ZaiNar achieves sub-10cm accuracy on existing CBRS and cellular networks.
FAQ
What does ZaiNar do? +
ZaiNar uses patented phase-based signal processing and sub-nanosecond time synchronization to extract precise location data from ordinary radio signals that devices already transmit. The system achieves sub-10cm indoor and outdoor positioning accuracy without GPS, operating system permissions, or device manufacturer cooperation, functioning as a network-level positioning service rather than a handset-based solution.
How much does ZaiNar cost? +
Pricing is not publicly available. ZaiNar operates an enterprise B2B model with custom contracts. The company has secured over $450 million in contracts and memoranda of understanding, indicating deal-based pricing tailored to carrier and enterprise deployments.
What are alternatives to ZaiNar? +
GPS/GNSS systems (widely available but lack indoor accuracy), Ultra-Wideband (requires device hardware modifications), cellular-based positioning like A-GPS (lacks sub-meter accuracy), and LEO satellite alternatives like Xona Space Systems (more capital-intensive, requires new infrastructure).
Who uses ZaiNar? +
Target customers include telecom carriers, healthcare systems, construction companies, smart city municipalities, and industrial enterprises. The company is deployed commercially across healthcare (equipment tracking), construction (safety and progress monitoring), smart cities, and industrial applications on multiple continents, though specific customer names are not disclosed.
How does ZaiNar compare to LEO satellite positioning solutions? +
ZaiNar leverages existing terrestrial radio infrastructure to achieve sub-10cm accuracy with 1.5km range and zero additional device battery drain, making it immediately deployable. LEO satellite solutions like Xona require new infrastructure investment and constellation deployment, offering global coverage but at higher cost and longer development timelines.
What makes ZaiNar different from standard cellular positioning? +
ZaiNar's sub-nanosecond time synchronization is 1,000× more precise than standard network timing, enabling sub-meter accuracy. Traditional cellular positioning relies on GPS assistance or triangulation with meter-level accuracy; ZaiNar operates as a network function providing sub-10cm precision without handset GPS or OS-level dependencies.
What is ZaiNar's competitive advantage? +
ZaiNar achieves sub-10cm accuracy using existing radio infrastructure (CBRS, cellular) with no device modifications, no battery drain on tracked assets, and independence from operating system permissions or manufacturer cooperation. Competitors either require new satellite infrastructure (Xona, Starlink PNT), device hardware changes (UWB), or lack indoor accuracy (GPS). ZaiNar's patented signal processing and timing technology provides immediate deployment and network-scale positioning.
