Abstract: An end device in a ZIGBEE communication protocol wireless network includes a memory configured to store computer-executable instructions and a processor coupled to the memory and configured to execute the instructions. The processor sends a first data frame to a first network device using a first network transmission power level and receives a first acknowledgment frame from the first network device. The first acknowledgement frame includes a first transmission power information element, and the first transmission power information element includes a second transmission power level. The processor updates a power control information table entry with the second transmission power level and sends a second data frame to the first network device using the second transmission power level.

Abstract: In a method for transmitting frames of data across a physical media that has a selective frequency response, a packet of data bytes is received by a media access (MAC) layer of a communication protocol from a local application for transmission to a remote receiver. The packet of data bytes is padded to from a padded packet of data bytes having a predetermined frame length, wherein the predetermined frame length is a frame length that is predetermined to provide correct transmission of a frame of data across the physical media that has a selective frequency response. The padded packet of data bytes is encoded by a physical (PHY) layer of the communication protocol to form multiple tone symbols. The multi-tone symbols are then transmitted on the physical media to the remote receiver.
