Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter may detect at least one distance between the transmitter and a receiver. The transmitter may transmit, to the receiver, information using a selected band of a wide band or a narrow band, where the selected band is based at least in part on the at least one distance. Similarly, in some aspects, a receiver may detect at least one distance between the receiver and a transmitter. The receiver may receive, from the transmitter, information using a selected band of a wide band or a narrow band, where the selected band is based at least in part on the at least one distance. Numerous other aspects are described.

Abstract: Systems and methods of managing a Bluetooth SigMesh network involve a supervisor configured to monitor one or more network parameters of the SigMesh network, such as topology, message identity, transmit count, transmit interval, relay retransmit count, or relay retransmit interval. The supervisor determines whether one or more of the network parameters are to be adjusted for improving transmission efficiency, reducing traffic congestion, avoiding flooding of packets on the mesh network, or ensuring injection of packets in the SigMesh network. The supervisor provides feedback to one or more nodes with the adjusted network parameters to improve transmission efficiency and reduce traffic in the SigMesh network.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for wireless range extension for communication in a wireless local area network (WLAN). In some aspects, a first WLAN device and a second WLAN device may exchange one or more management frames advertising support for a non-orthogonal frequency-division multiplexing (non-OFDM) data rate for communications via one or more non-2.4 GHz bands. In some aspects, the non-OFDM data rate may be a data rate of a plurality of data rates associated with an IEEE 802.11b standard, and the one or more non-2.4 GHz bands may include one or more of a 3.5 GHz band, a 5 GHz band, a 6 GHz band, a 45 GHz band, and a 60 GHz band. The first and second WLAN devices may select the non-OFDM data rate and at least one of the non-2.4 GHz bands for exchange data communications.
