1. A method for characterize a communication channel on a communication network, comprising:
- a) receiving within a network node at least one silent symbol transmitted together with a packet; and
b) determining within the network node the amount of energy received by the network node during the silent symbol.

24. A method of characterizing a communication channel of a network including:
-
a) in a node of the network, zeroing at least one of the subcarriers in the payload symbols; and b) transmitting from a transmitting node the at least one subcarrier with the zeroed payload symbols. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31)

32. A method of characterizing a communication channel of a network including:
-
a) receiving in a node of the network at least one silent subcarrier transmitted by another node of the network, the payload symbols of the silent subcarrier having been zeroed; and b) in the receiving node of the network, measuring the energy received in frequency bins of the at least one silent subcarrier.

33. A method of characterizing a communication channel of a network including:
-
a) transmitting instructions from a network coordinator to a network node, the instructions instructing the network node to transmit a silent symbol; and b) receiving from the network node an indication of the amount of energy present on a subcarrier on which the silent symbol was transmitted. - View Dependent Claims (34, 35)
