A multicarrier communication device using orthogonal frequency division multiplexing (OFDM) symbols can vary the number of subcarriers being used on multicarrier communication within a network, based on a predetermined criterion and capability information. The capability information can include a data file, which indicates portions of an electromagnetic spectrum for which regulatory body licenses are currently obtained for a network cell. Alternatively, the capability information can include capability information about the wireless devices in communication with the multicarrier communication device, where the capability information for each wireless device includes device power limitations, device bandwidth width limitations, or which subcarriers a wireless device is capable of using. |
