| 1. A method for frame execution, comprising:
waiting for a frame synchronization;
upon frame synchronization occurring, accessing a slot of a slot allocation for a node;
determining a mode associated with the slot allocation wherein the mode is one of a transmit mode, a none mode, and a receive
mode;
if the mode is transmit,
transmitting using the slot allocation then checking for another slot;
if the mode is none,
checking for another slot;
if the mode is receive,
activating a receiver;
checking for signal;
if there is no signal,
storing first error information;
determining if failure rate exceeds a first threshold value for use of the slot;
if there is signal, determining if information received was received within an acceptable error rate;
if there is signal and if the information was received within the acceptable error rate,
processing incoming data; and
checking for another slot.
