Claim:
1. A downhole telemetry system that comprises: a tubular for use in a bore hole; and an array of near-field electromagnetic communication devices disposed along the tubular, said near-field electromagnetic communication devices relaying information along the tubular bidirectionally, wherein said near-field electromagnetic communication devices are adjacent and spaced at least a foot apart, wherein a first near-field electromagnetic communication device of the near-field electromagnetic communication devices is attached to an external to the tubular and is protected by an upset of a box end of a tubular joint of the tubular, wherein a second near-field electromagnetic communication device of the near-field electromagnetic communication devices is communicative with the first near-field electromagnetic communication device to relay the information bidirectionally using Long Wavelength electromagnetic signals, the second near-field electromagnetic communication device attached to the external of the tubular and protected by an upset of a pin end of the tubular joint of the tubular, wherein each of the near-field electromagnetic communication devices comprises a corresponding RuBee device of a plurality RuBee devices, wherein each of the first and the second near-field electromagnetic communication devices comprises the corresponding RuBee device that automatically links to other corresponding RuBee devices in the array of the near-field electromagnetic communication devices, and wherein the first and the second near-field electromagnetic communication devices are operable for an expected lifetime of the tubular joint to establish links with other in-range of the near-field electromagnetic communication devices to relay the information bidirectionally.
