摘要：
The invention is directed to methods and systems for generating frequency reference signals from a radio signal received from a large-coverage access component, such as a base station. The radio signal is received and processed by an oscillator to filter out abnormalities. Consequently, a frequency reference signal is generated that is encapsulated into packets and delivered to one or more small-coverage access components using the Precision Timing Protocol or some other protocol that is useable by the small-coverage access components. The small-coverage access components comprise one or more of a femtocell or a picocell.
