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 ${7.1}\times {10}^{-{12}}$ 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.

无线毫米波载波上的白兔子时间和频率传输

我们演示了使用白兔（WR）时间传输系统在毫米波（mm-wave）71–76 GHz载波上进行时间和频率传输。为了验证我们系统的性能，我们提出了重叠的艾伦偏差（ADEV），时间偏差（TDEV）和相位统计数据。对于毫米波载波，我们报告的ADEV为 $ {7.1} \次{10} ^ {-{12}} $ 在1 s时和TDEV在10 s时<10 ps 我们的结果表明，在平均4 s后，我们具有足够的精度来传输铯原子频率标准。我们分析了毫米波链路的链路预算和架构，并讨论了相位误差的可能来源及其对WR频率传输的潜在影响。我们的数据表明WR可以同步新的网络体系结构，例如物理上分离的光纤网络，并支持新的应用程序，例如间歇性连接的平台的同步。最后，我们提出了针对未来研究的建议，包括级联的混合有线和无线架构。
