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
