Building materials, low GNSS signal strength, or other restrictions can sometimes interfere with indoor small cell synchronization using GNSS PTP grandmaster timing systems. It is the integrated integrated grandmaster IGM 1100o of Microchip that solves this problem. Like the indoor version, this compact IGM grandmaster provides precise and stable time information indoors to serve small cells in the interior. However, the IGM 1100o is reinforced to work in a wider temperature range, so it can also be installed in the attic of a building instead of an interior wall or ceiling.
Outdoor Integrated IGM Grand Master can be used safely in environments where outdoor temperature restrictions and resistance to environmental conditions are essential requirements, such as outdoor cabinets and small structures.
