This standard will fill critical gaps, as today no IEEE standard exists for Smart Grid devices installed in substations, on distribution feeders, or the communications devices installed in Smart Meters—and utilize radio frequency, power line communications, or Ethernet cables. This standard (as an extension of IEEE Std 1613-2009) will fill those gaps. It adds new frequencies, now in use by cell phones and portable devices, not covered in IEEE Std 1613-2009. It also adds five new immunity tests (Clause 6 and Clause 9 through Clause 12) not previously covered by any IEEE standard. Thus, Clause 6 and Clause 9 through Clause 12 are additional requirements for IEEE 1613 devices.
