A wireless telemetry system for providing signal communication across a wired-communication gap in a bottom-hole assembly 14 ("BHA"), the BHA 14 having an upper portion 8 and a lower portion 6 separated by the wired-communication gap 4, includes, an upper transceiver (12a) positioned in the upper portion and in signal communication with a surface telemetry system and a lower transceiver 12b positioned in the lower portion and in signal communication with a drilling tool 43, the upper and the lower transceivers in signal communication with one another via wireless induction telemetry. Each transceiver may include an antenna 40 that is positioned within the bore of a drill collar adjacent to a thinned wall section in the drill collar. The thinned wall section may include one or more of increasing an inside diameter relative to a base inside diameter of the bore and decreasing an outside diameter relative to a base outside diameter of the drill collar. Also claimed is a wireless telemetry system for providing communication between two wellbore tools, the system comprising a first transceiver in communication with a first wellbore tool and a second transceiver in communication with a second wellbore tool, the first and second transceivers being in communication with each other via wireless induction telemetry. The first wellbore tool may be a surface mud-pulse telemetry system. |
