Abstract
A method and apparatus are provided for converting a precision time protocol (PTP) to a GPS signal. Enterprise versions of Femtocells are located within buildings and do not have access to a GPS signal directly from a GPS satellite. An adapter is provided that takes an available PTP and power over Ethernet (PoE) flow and converts the signal into a pseudo-GPS signal that acts as a timing input into the Femtocell. The pseudo-GPS signal is a GPS signal modulated at the L1 band frequency or 1575.42 megahertz, but does not have location data nor subframes 1, 2, or 3, as found in an ordinary GPS signal.
