Application Radio Interface Backhaul
Frequency Phase Frequency Phase
CDMA 2000 ±50ppb ±3 to 10µs GPS GPS
GSM/WCDMA ±50ppb n/a ±16ppb n/a
LTE (FDD) ±50ppb n/a ±16ppb n/a
LTE (TDD) (large cell) ±50ppb ±5µs ±16ppb ±1.1µs
LTE (TDD) (small cell)
±50ppb ±1.5µs ±16ppb ±1.1µs
LTE-A MBSFN ±50ppb ±1 to 5µs ±16ppb ±1.1µs
LTE-A CoMP* ±50ppb±500nsec to
5µs±16ppb 500ns - ±1.1µs
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 anew 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
