Abstract
An active downhole antenna located in a borehole receives electromagnetic (EM) telemetry transmissions from sources in adjacent boreholes. The antenna comprises a processor operable do decode and measure signal to noise ratio of received transmissions. Data received at the active antenna is transmitted to surface using a high-speed data communication network. The active antenna may handle data communications from multiple downhole EM telemetry transmitters.
