Optimized distribution of wireless broadband in a building

A communications system comprising:

• a transmitter of a broadband wireless training sequence comprising multiple orthogonal subcarriers;
• a ventilation system within a building, the ventilation system comprising multiple ducts and multiple ventilation openings;
• at least one antenna in communication with the transmitter, the at least one antenna being positioned within a duct, the at least one antenna being operative to transmit the wireless broadband training sequence from the transmitter, with transmission occurring from a single location;
• at least one receiver located within the building, the receiver being configured to receive the wireless broadband training sequence;
• a processor;
• and
• a non-transitory machine-readable medium having encoded thereon a set of instructions executable by the processor to perform one or more operations, the set of instructions comprising:
• instructions to analyze a parameter of the wireless broadband training sequence received by the receiver;
• and
• instructions to optimize a subsequently transmitted wireless broadband signal based at least in part upon the analyzed parameter of the wireless broadband training sequence.
