A micro-machined MEMS resonator gyroscope and accelerometer is fabricated from an epilayer semiconductor wafer to incorporate a substantially planar, H-shaped resonator mass suspended from a support plate by two opposed elongated springs that couple to the relatively short crossbar member of the H. In particular, the cathode active material comprises -phase silver vanadium oxide prepared by using a -phase silver vanadium oxide starting material. The second gateway receives a call request from the first gateway for the communication device.
