Highly Accurate Location without GPS

ZaiNar announced commercial availability of its 5G positioning technology, the first 5G location system that operates entirely independent of device makers, using the network as a sensor (i.e., connectivity signals that devices already transmit) to deliver sub-10cm accuracy at ranges up to 1.5km. The network-side solution achieves sub-10cm accuracy using only existing connectivity signals, requiring no software on user devices, no dedicated positioning hardware, and consuming zero additional battery. Operating on as little as 10 MHz of spectrum, ZaiNar is the only 5G positioning system that works on bandwidth-constrained private 5G and low-power 5G IoT networks, the environments where location services can be worth more than the connectivity itself.

"5G's killer app has finally arrived, and it's not theory, it's deployed," said Daniel Jacker, CEO and Co-Founder of ZaiNar. "We're proving sub-10cm accuracy in real-world deployments across healthcare, construction, logistics, and smart city applications. This technology turns 5G from a faster pipe into genuine infrastructure for Physical AI."

"ZaiNar's submeter location is the unlock for Physical AI. It brings forward telcos as a key piece of the Physical AI ecosystem by providing the missing data layer, both for real-time coordination and training grounded in real-world 2D and 3D vectors. The enterprise applications span traffic management, advertising, logistics, and healthcare. ZaiNar's solution outperforms alternatives and works across both WiFi and 5G, including wide-area carrier networks and private deployments. Due to the size of the opportunity, I have joined as a board advisor," said Nishant Batra, Board Advisor, ZaiNar; Former CTO, Nokia.

Unlike conventional approaches that rely on dedicated positioning reference signals (PRS or PSRS), ZaiNar's patented technology uses the connectivity signals (SRS) that every device already transmits. PRS and PSRS signals can only be sent once per second, limiting them to stationary use cases. SRS signals are transmitted 100 to 500 times per second, enabling ZaiNar to track fast-moving objects, such as vehicles, drones, robots, mobile workers, in real time.

Today, mobile operating systems made by Apple and Google determine whether a device shares its positioning signals with the network. In practice, both deny PRS and PSRS requests by default, granting access only where legally required, such as E911 emergency services. This means carriers have invested billions in 5G infrastructure but cannot offer location services on the handsets connected to their own networks.

ZaiNar's SRS-based approach changes this equation entirely. Because SRS is a connectivity signal, the device must transmit it to maintain its network connection — positioning becomes a network function, not a handset function. Carriers and enterprises gain direct access to sub-10cm location data on every phone, robot, car, or IoT device, with no dependence on operating system permissions, app-level access, or device manufacturer cooperation. In terms of power, compute, and security, this shift from device-side to network-side positioning represents a significant improvement in 5G utility.

ZaiNar has demonstrated sub-10cm accuracy on CBRS Band 48 networks with just 20MHz bandwidth. Additional proven capabilities include 1.5km read range and zero additional battery drain on tracked devices. ZaiNar is not only the best positioning method across 5G cellular, it's the best location service across any modality, including GPS RTK, Ultra-wideband (UWB), WiFi, Bluetooth, and RFID.
