Abstract
A method for dynamically selecting one of a plurality of base stations for provision of timing information. A base station compares satellite signal strengths measured at satellite-positioning-system receivers of a plurality of base stations, such as the plurality of base stations in a local area network (LAN) for instance. The base station then selects one of the plurality of base stations to provide timing information based at least in part on the comparison, such as the one base station having the greatest satellite signal strength for instance. The base station then operates according to timing information indicated by satellite data from the selected base station. Advantageously, this method can help to increase the accuracy and reliability of the timing information.
