Patent ID: 7068973

Claim:
A method of retransmitting a GPS signal inside a structure, the method comprising: receiving the GPS signal with a link antenna positioned to receive signals from outside of the structure; with a primary repeater coupled to the link antenna, down converting the GPS signal to an intermediate frequency (IF) signal, amplifying and filtering the IF signal, and up converting the IF signal to produce a radio frequency (RF) signal; with a broadcast antenna coupled to the primary repeater, wirelessly transceiving the RF signal with a secondary repeater configured for transceiving signals inside the structure; at the secondary repeater, transceiving the RF signal with a link antenna; downconverting the RF signal to a second intermediate frequency (IF) signal; amplifying and filtering the second IF signal; upconverting the second IF signal to a second GPS signal; and with a broadcast antenna of the secondary repeater, transceiving the second GPS signal with GPS equipment inside the structure.
