While time synchronization has always been essential for wireless networks to function, requirements have evolved dramatically as operators increase small cell use and optimize spectrum usage to enable 4.5G, 4.9G and 5G network capabilities. Accurate phase synchronization is now increasingly critical to support new features and services in these networks. For example, coordination between base stations for broadcast video delivery and interference mitigation between macro base stations and small cells in dense deployments drive the need for strict phase specifications.
With technology innovations engineered to address these challenges, Microsemi offers a portfolio of small form factor IEEE 1588 PTP grandmasters to deliver a cost-effective, precise timing master exactly where it’s needed, such as small cells and backhaul to eNodeBs for wireless service delivery at the LTE network edge. Microsemi’s IGM 1588 grandmasters integrate both GNSS antenna and GNSS receiver, eliminating the need for an outdoor antenna and cabling.
The IGM’s latest release 3.0 software and new hardware model (IGM Plus) enables deployment of these smaller grandmasters at the very edge of mobile networks, lowering operator costs and improving customer experience with enhanced coverage and performance. Easily installed indoors or outdoors, in-building or in cabinets or huts, the IGM grandmaster family serves operators preparing for 5G through densification, along with enterprises seeking enhanced indoor capacity and coverage on LTE and LTE-Advanced (LTE-A) networks.
