1. A method of assigning use of a bandwidth for radio communication, the method comprising the following steps:
a. generating an initial frame, the initial frame comprising a series of allocations;
b. generating a further frame, the further frame comprising a series of allocations;
c. repeating step b. to generate a matrix of allocations;
d. shuffling at least two columns or at least two rows within the matrix;
e. selecting one or more columns or rows in the matrix, wherein each selected column or row represents a selected sequence;
f. assigning use of the bandwidth according to the one or more selected sequences; and
g. transmitting one or more data streams on the assigned bandwidth
wherein the step of generating the initial frame comprises pseudo-random generation using a shuffle algorithm, and wherein the pseudo-random generation comprises using an external random number generator to generate a pseudo-random number based on time of day.
