1. An apparatus for inclusion in a node of a wireless network, the apparatus comprising:
a receiver to receive data from a remote node, including an analog-to-digital converter producing samples of signals received at the node from the remote node, said received signals in the form of packets of data;
a demodulator coupled to the receiver to demodulate samples of the signals received at the receiver to produce demodulated signals, the samples at decision points; and
an error vector magnitude calculator coupled to the receiver to determine a measure of the signal quality of the decision point samples of the received signal, such that the EVM measure determined by the EVM calculator can be used to select a data rate for communicating between the node and the remote node.
