OSA 5405-MB – precise edge timing for 5G and smart cities

Introducing the industry's first ultra-compact outdoor PTP grandmaster clock with multi-band GNSS receiver and integrated antenna. Part of the OSA 5405 Series of smart synchronization devices for indoor or outdoor deployment, our new OSA 5405-MB ensures timing accuracy by eliminating the impact of ionospheric delay variation. This empowers communication service providers (CSPs) and enterprises to deliver the nanosecond precision needed for 5G fronthaul and other emerging time-sensitive applications.

OSA 5405-MB – precise edge timing for 5G and smart cities

  1. 1. OSA 5405-MB – precise edge timing for 5G and smart cities April 2021 Combining a multi-band GNSS antenna with a PTP grandmaster and NTP server
  2. 2. © 2021 ADVA. All rights reserved. 2 The better is the enemy of the good Requirements: Highly precise and resilient synchronization in an outdoor application Mobile base stations Access to accurate, secure timing under difficult environmental conditions Industrial control, manufacturing Robust timing, frequently limited access to roof space for antenna mounting Finance, data centers GNSS antenna Coaxial cable PTP grandmaster with GNSS receiver Good enough ?
  3. 3. © 2021 ADVA. All rights reserved. 3 Synchronizing sites and applications Requirements: Simpler installation Integrated solution Higher accuracy GNSS antenna Coaxial cable PTP grandmaster with GNSS receiver Good enough ? Optimized solution OSA 5405-MB  Integrated antenna  Robust multi-band receiver  Ruggedized design  PTP/NTP directly from the antenna PTP/NTP
  4. 4. © 2021 ADVA. All rights reserved. 4 Improving accuracy of GNSS receivers • Communication in L1 and L2 band • Dual measurements make it possible to compensate for ionospheric delay variations • Multi-band GNSS receivers achieve time accuracy of better than 10ns (typical) Multi-band GNSS receiver Lower L-band Upper L-band Delay difference Ionospheric disturbance 0 10 20 30 40 50 ns Ionospheric daily delay variation 0:00 3:00 6:00 9:00 12:00 15:00 18:00 21:00 0:00 Nanosecond time accuracy with multi-band GNSS receivers
