Abstract
Approaches enable multi-standard communications between wireless sensor nodes for wireless sensor networks. For example, approaches enable wireless communications between devices where each device may use a different wireless transmission protocols, via one or more multi-standard intermediate devices. The multi-standard intermediate device can include a multi-band radio frequency front-end unit that includes a first frequency digitalization pathway and a second frequency digitalization pathway, and a multi-band radio frequency back-end unit that includes a multi-band analog pathway to implement such approaches.
