IGM for External GPS Antenna
IEEE 1588 Integrated Grandmaster with GPS Antenna (IGM-1100x) v2
In certain scenarios, there may be a pre-existing GNSS antenna in a location where the GNSS cabling would be short enough to be inexpensive and easily installed. In such a situation, the most cost-effective solution is to deliver precise time and phase with a low cost IEEE 1588 PTP grandmaster connected to the external GPS antenna.
Microsemi’s small form factor IEEE 1588 IGM grandmaster, IGM-1100x, with integrated GNSS receiver and external antenna delivers precise time in scenarios where a GNSS antenna is already deployed, or where it would be cost-effective to deploy, such as a small one-story building, rack, hut or a cabinet. A single Ethernet connection is used for auto-configuration management, with Power over Ethernet used for IGM and PTP grandmaster operations to precisely synchronize eNodeBs. The plug-and-play operation, leveraging DHCP and TR-069 communication to the Auto Configuration Server (ACS), is meant for quick and easy installation similar to installing a typical indoor Wi-Fi antenna hot spot.
IGM-1100x provides a cost-effective alternative to existing 1588 grandmasters which typically present space, power and cost consideration hurdles.
Microsemi offers a unified software across the IGM grandmaster portfolio, facilitating densification for mobile operators through enhanced management options, more reliability through GPS backup, greater scalability with IPv6 and increased client support.
