1588v2

Conventional time synchronization is implemented using NTP. NTP implements millisecond time synchronization; however, it cannot reach the microsecond time precision required by wireless base stations. GPS is currently used on base stations to implement frequency and time synchronization.

1588v2 implements sub-microsecond time synchronization, which has a precision similar to GPS but is advantageous in low costs and high maintainability and security. 1588v2 offers the following benefits:

• Space localization: 1588v2 obtains the system clock directly from synchronous systems on the ground and is intended for LANs (including but not limited to Ethernet networks) using multicast communications.
• High synchronization precision: 1588v2 offers sub-microsecond synchronization precision and perfect state machine; it is management-free with minimal human intervention needed.
• Low costs: Minimal network resources and low processing power are needed.
