  2. Frame synchronization - Wikipedia

    The search can be sequential (only consider one starting point at a time), or multiple candidate starting points may be considered at once. Advanced techniques continue searching even while synchronization is established, so that, if synchronization is lost, by the time the loss is noticed a new frame start position has been found. [2]

  3. Synchronization in telecommunications - Wikipedia

    en.wikipedia.org/wiki/Synchronization_in...

    Thomas Edison achieved synchronization in his stock ticker with a clunky but effective unison mechanism to resynchronize periodically. [2] In the teleprinter world, Howard Krum finally came up with a good decoding mechanism for async signals around 1912. [3] Synchronization remained a problem well into the electronic era.

    Synchronization sources available to a network element are: [citation needed] Local external timing This is generated by an atomic cesium clock or a satellite-derived clock by a device in the same central office as the network element. The interface is often a DS1, with sync-status messages supplied by the clock and placed into the DS1 overhead.

    Notes: All speeds are theoretical maximums and will vary by a number of factors, including the use of external antennas, distance from the tower and the ground speed (e.g. communications on a train may be poorer than when standing still). Usually the bandwidth is shared between several terminals.

  7. Data synchronization - Wikipedia

    en.wikipedia.org/wiki/Data_synchronization

    Data synchronization is the process of establishing consistency between source and target data stores, and the continuous harmonization of the data over time. It is fundamental to a wide variety of applications, including file synchronization and mobile device synchronization.

  8. Precision Time Protocol - Wikipedia

    en.wikipedia.org/wiki/Precision_Time_Protocol

    Synchronization and management of a PTP system is achieved through the exchange of messages across the communications medium. To this end, PTP uses the following message types. Sync, Follow_Up, Delay_Req and Delay_Resp messages are used by ordinary and boundary clocks and communicate time-related information used to synchronize clocks across ...

    Since 5G is a relatively new type of service, only phones which are newly released or are upcoming can support 5G service. Some of these phones include the iPhone 12/13; select Samsung devices such as the S21 series, Note series, Flip/Fold series, A series; Google Pixel 4a/5; and a few more devices from other manufacturers.
