Claim 21:
22. The mobile device of claim 21, wherein the transmission path is a primary transmission path that includes a first switch in the RF switch network and the reception path is a secondary reception path that includes a second switch in the RF switch network, wherein the mobile device further has a primary reception path that includes the first switch and a secondary transmission path that includes the second switch, wherein the at least one processor is further configured to:
switchably couple the first switch in the primary transmission path to the second switch in the secondary reception path to receive the first signal on the reception path in the conducted closed loop;
switchably couple the first switch in the primary transmission path to a third switch in a third reception path and to send a second signal on the primary transmission path and to receive the second signal on the third reception path;
switchably couple the second switch in the secondary transmission path to the first switch in the primary reception path and to send a third signal on the secondary transmission path and to receive the third signal on the primary reception path; and
switchably couple the second switch in the secondary transmission path to the third switch in the third reception path and to send a fourth signal on the secondary transmission path and to receive the fourth signal on the third reception path;
wherein the at least one processor is configured to determine the second transmission and reception group delay by being configured to determine a first group delay for the primary transmission path and the primary reception path and a second group delay for the secondary transmission path and the secondary reception path based on times of departure and times of arrivals of transmitted and received first signal, second signal, third signal, and fourth signal.
