The multi-hop and single-hop methods can also be operated in series, for example, so that data from the Measuring-While-Drilling tool located in the Bottom-Hole-Assembly are first carried with the single-hop telemetry method and then transferred to the multi-hop telemetry method at one or more node(s) close to the surface. Preferably, the multi-hop telemetry method can also carry data from along-string sensors. Another combined telemetry system that can be used while drilling a wellbore consists of two single-hop telemetry methods combined in parallel.
