WR is an innovative solution to provide sub-ns accuracy and picoseconds
precision of synchronization over large distances.
The number of WR applications and their specifications have exceeded the original The number of WR applications and their specifications have exceeded the original
assumptions of the project. expectations of the project.
This proliferation can be attributed to the fact that WR is based This proliferation can be attributed to the fact that WR is standard, open and
on standards and it is openly as well as commercially available while meeting commercially available. The open nature of WR allows its users to contribute to the
very stringent synchronization requirements. The open nature of WR allows its users to contribute to the
project with their project with their
