the intelliserv network components are embedded in drill string components, known as intellipipe, which transmit subsurface data at 57,000 bits per second. the intelliserv network upgrade can raise the speed to one million bits per second. the two-way data communication between downhole measurement while drilling (mwd) and logging while drilling (lwd) measurement tools and the operators at the surface allow the operators to command rotary-steering tools, or configure downhole tools such as the formation pressure testing tool or sonic tools.
