Abstract

An apparatus, system and method for measuring timing of a signal transmitted from a wireless base station antenna. The apparatus and system include a wireless base station antenna that transmits a first signal, and a transmission timing measurement apparatus having a first antenna and a second antenna that receives an accurate time value and the first signal, and that outputs an offset of the first signal from the accurate time value. The method includes receiving an accurate time, receiving the reception time transmitted from the wireless base station antenna, receiving the reception time value and the accurate time value, and comparing of the reception time value and the accurate time value.
