Abstract: Switching between and/or combining various multi-transceiver wireless communication techniques based on a determined characteristic of a network or a wireless link is described herein. As an example, a characteristic such as signal to noise ratio (SNR), multi-path scattering, available bandwidth, or the like, can be determined. The characteristic can then be compared with suitable thresholds for various multi-transceiver communication techniques, such as MIMO, multi-channel concatenation, channel diversity, and so on. Based on a comparison of the characteristic and the thresholds, a suitable multi-transceiver technique can be selected and implemented for the wireless link. Accordingly, a network can provide increased data rates and/or channel quality from a multi-transceiver technique that is most suited to prevailing conditions of the wireless network/link.

Abstract: In embodiments of virtual addressing for mesh networks, a node in a mesh network publishes packets and/or subscribes to packets using a virtual address that is derived from a unique identifier. The unique identifier has a larger address space than the destination address field of the packet. The unique identifier and an application key are hashed to elide the unique identifier from the destination address that is transmitted in the packet over the mesh network. A node receiving the packet can determine that the address is a virtual address, and disambiguate the destination address to determine that the virtual address corresponds to a unique identifier known to the receiving node.

Abstract: According to certain embodiments, a method by a radio node (110, 115) operating in multiple modes for power detection includes operating in a first mode. While operating in the first mode power levels of transmissions on a channel are compared to a first threshold to determine whether the channel is free. While operating the radio node (110, 115) in the first mode, power levels within a specified range are detected during a first time period. In response to detecting the power levels within the specified range during the first time period, the radio node (110, 115) is switched to a second mode that is a duty-cycle mode. While operating the radio node (110, 115) in the second mode, the power levels of the transmissions on the channel are compared to a second threshold during a first portion of a duty cycle and to a third threshold during a second portion of the duty cycle to determine whether the channel is free. The third threshold is different from the second threshold.
