Integrated GNSS Grandmaster
Precise synchronization of indoor small cells requires a GPS timing source, especially for phase applications. In some scenarios, installing a GPS antenna on the roof of the building or enabling each small cell with GPS can be complicated and expensive. The Microchip IGM 1100i addresses this use case.
