Described herein are devices, systems, methods, and processes for optimizing the utilization of large bandwidth channels in wireless communication networks. This is achieved by an access point (AP) identifying parts of the channel available for standard power (SP) transmissions and using novel puncturing messages to allow simultaneous low-power indoor (LPi) transmissions on the “punctured” parts of the channel. The AP can implement different modes to allow concurrent transmissions at SP level on the SP-allowed parts of the channels and at LPi level on part of the channel that do not allow SP transmissions. The AP can also switch unicast communication with a client device to LPi but with a larger channel width as the device nears the AP. The techniques allow for fuller utilization of large bandwidth channels where only a part of the channel is available for SP transmissions, thereby improving network efficiency.
