IGM-1100 Outdoor Integrated GNSS Master

The synchronization needed for indoor small cell operations requires a high-accuracy timing receiver nearby. Until now, this proximity required an expensive and often complicated GNSS antenna installation for a few small cells.

In some scenarios, it is not possible to deploy the IGM-1100i due to limited building materials, urban canyons, or other constraints.

Microchip’s IGM-1100 (also referred to as the Outdoor IGM) addresses this use case.

The IGM-1100o brings precise timing indoors and serves indoor small cells, but is located on the roof of the building instead of on a wall or ceiling.
