“…At 1 s, we measured an ADEV of 3.7 × 10 −12 and 7.1 × 10 −12 for fiber and mm-wave configurations, respectively. For both configurations, we measured a TDEV of <10 ps at 10 000 s. Analysis has been conducted, showing that WR over mm-wave can support subnanosecond synchronization [23]. Our results demonstrate subnanosecond frequency transfer and timing jitter.…”

We demonstrate time and frequency transfer using a White Rabbit (WR) time transfer system over millimeter-wave (mm-wave) 71-76 GHz carriers. To validate the performance of our system, we present overlapping Allan deviation (ADEV), time deviation (TDEV), and phase statistics. Over mm-wave carriers, we report an ADEV of 7.1 × 10 −12 at 1 s and a TDEV of <10 ps at 10 000 s. Our results show that after 4 s of averaging, we have sufficient precision to transfer a cesium atomic frequency standard. We analyze the link budget and architecture of our mm-wave link and discuss possible sources of phase error and their potential impact on the WR frequency transfer. Our data show that WR can synchronize new network architectures, such as physically separated fiber-optic networks, and support new applications, such as the synchronization of intermittently connected platforms. We conclude with recommendations for future investigation, including cascaded hybrid wireline and wireless architectures. Index Terms-Millimeter wave (mm-wave), time transfer, White Rabbit (WR), wireless.
