iPosi is a privately funded startup founded in 2011, based in Colorado, US. The company is focused on serving the growing demand for precise, jam-resistant, time synchronization, and accurate mobile and fixed device indoor positioning.
The company provides patented technology which can be embedded in Small Cells, mobile and emerging M2M, VoIP, and certain time sensitive elements within "Internet of Things" networks.
Solution Description
The technology uses Global Navigation Satellite Systems (GNSS) such as GPS, augmented by regionally based time servers that distribute a data feed to all iPosi devices in their area. The embedded iPosi software within each small cell uses this to detect and decode multiple GNSS radio signals which might otherwise be out of range.
This allows Small Cells to receive accurate time and location information even in the harshest indoor and cluttered urban environments.
LTE, especially TD-LTE, requires microsecond phase timing accuracy to work efficiently with nearby cells. Some LTE Advanced features demand even tighter tolerances. iPosi's solution provides a stable 100ns timing source inside high rise buildings.
The need for accurate indoor location information is also a growing requirement, such as for E911 emergency calls. iPosi's iP-GPS provides that accuracy in a cost effective and easily understood manner.
Commercial Progress
iPosi successfully demonstrated their indoor solution at Small Cells Americas 2013, operating in the ground floor level within a large conference venue at very low signal levels down to 176dBM.
