1. A method comprising:
- during a transmit opportunity time interval for a wireless network device, sending a transmission in a primary channel in a frequency band in which the primary channel and a secondary channel may be used simultaneously to send a wider bandwidth transmission;
monitoring activity in the secondary channel;
determining whether the secondary channel is free based on the monitoring; and
when it is determined that the secondary channel is free, sending the wider bandwidth transmission in the primary and secondary channels.

Abstract
Wider bandwidth transmissions are dynamically enabled in a wireless networking environment. During a transmit opportunity time interval for a wireless network device, a transmission is sent in a primary channel in a frequency band in which the primary channel and a secondary channel may be used simultaneously to send a wider bandwidth transmission. Activity is monitored in the secondary channel. A determination is made as to whether the secondary channel is free based on the monitoring. When it is determined that the secondary channel is free, the wider bandwidth transmission is sent in the primary and secondary channels.

21. An apparatus comprising:
-
a first radio subsystem configured to, during a transmit opportunity time interval, send a wireless transmission in a primary channel in a frequency band in which the primary channel and a secondary channel may be used simultaneously to send a wider bandwidth transmission; and a second radio subsystem configured to monitor activity in the secondary channel to determine whether the secondary channel is free, and when it is determined that the secondary channel is free, causing the first radio subsystem to send at least a portion of the wider bandwidth transmission in the primary and secondary channels. - View Dependent Claims (22, 23, 24, 25, 26, 27)

28. One or more computer readable storage media encoded with software comprising computer executable instructions and when the software is executed operable to, in a wireless network device:
-
during a transmit opportunity time interval for the wireless network device, cause a transmission to be sent in a primary channel in a frequency band in which the primary channel and a secondary channel may be used simultaneously to send a wider bandwidth transmission;
monitor activity in the secondary channel;determine whether the secondary channel is free; and when it is determined that the secondary channel is free, cause the wider bandwidth transmission to be sent in the primary and secondary channels. - View Dependent Claims (29, 30)
