This document summarizes Time4 Systems, a startup company developing cost-effective synchronization solutions for access networks. It has 6 employees and two solutions: Mini-GM and GNSS in SFP format, and Mini-GM integrated in a GNSS antenna. The solutions help meet stringent synchronization requirements for 4G and 5G networks by distributing timing accurately throughout the network in a simplified and cost-effective manner. Acquisition of Time4 Systems would expand Oscilloquartz's portfolio and provide a complete R&D team with expertise in synchronization technologies.

LTE-A eICIC* ±50ppb ±1 to 5µs ±16ppb ±1.1µs
Sync Application Challenge Addressed
* The performance requirements of the LTE-A features are under study by 3GPP
The new phase requirements of +/-500ns to 1500ns requires a
new timing distribution architectures and new standards!

Implementation Options for RAN Sync
• Option 1 – GPS/GNSS everywhere
• GNSS in every base station
• Very expensive
• No protection in case of local GPS/GNSS
outage
• Option 2 – PTP (& Sync-E) everywhere
• Full on path support (G.8275.1) –
GNSS+GM in the core – chain of BC/TC
• Require upgrading the entire network –
very expensive
• Option 3 – PTP over the last mile
• GPS+GM in the mobile aggregation
• Most cost effective solution
• Offer protection and scalability
