Want the best cellular positioning for massive IoT? hellaPHY outperforms all other cellular location technologies across all metrics from cost and accuracy to privacy, scalability, data usage and spectral efficiency. hellaPHY software enables the lowest cost, lowest power, lowest data utilization indoor/outdoor location using cellular networks with near GNSS accuracy.

PHY Wireless has developed an industry leading, truly scalable, low cost, positioning and location intelligence solution to enable high-accuracy and low-power location services on existing LTE and 5G networks. PHY Wireless’s algorithms bring infrastructure efficiency to carriers by extending spectral efficiency in a world of ever-increasing wireless devices. The company provides an efficient software version of its algorithms that can exist within a baseband MCU or on application processors.

The simple API allows for rapid integration into both current and new chipsets and allows for a FOTA update to enable the technology on existing products to bring immediate improvements over current implementations.

Using the sparsest PRS standardized by 3GPP, hellaPHY achieves unparalleled accuracy approaching that of GNSS solutions with the added benefit of working both outdoors as well as indoors.

hellaPHY also provides maximum privacy and security of location data. The position resides on the device with a high level of encryption, and at no time is the device location known to anyone except the device owner. It is not computed on, or stored in any cloud location by any third party.

The advanced edge computing allows operators to maximize the use of their spectrum assets by minimizing the amount of data transferred over the network, and is nearly 300x more network efficient than other cellular location approaches.


hellaPHY intelligent solutions support next-level precise positioning; products include:
