    en.wikipedia.org/wiki/Smart_antenna

    Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.

    en.wikipedia.org/wiki/Smart_speaker

    As of summer 2022, it is estimated by NPR and Edison Research that 91 million Americans (35% of the population over 18) own a smart speaker. [2] A smart speaker with a touchscreen is known as a smart display. [3] [4] It is a smart device that integrates conversational user interface with display screens to augment voice interaction with images ...

    en.wikipedia.org/wiki/MIMO-OFDM

    Multiple-input, multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) is the dominant air interface for 4G and 5G broadband wireless communications. It combines multiple-input, multiple-output technology, which multiplies capacity by transmitting different signals over multiple antennas, and orthogonal frequency-division multiplexing (OFDM), which divides a radio channel into ...

  6. Multi-user MIMO - Wikipedia

    en.wikipedia.org/wiki/Multi-user_MIMO

    Multi-user MIMO (MU-MIMO) is a set of multiple-input and multiple-output (MIMO) technologies for multipath wireless communication, in which multiple users or terminals, each radioing over one or more antennas, communicate with one another. In contrast, single-user MIMO (SU-MIMO) involves a single multi-antenna-equipped user or terminal ...

    Amazon Alexa, or, Alexa, [2] is a virtual assistant technology largely based on a Polish speech synthesizer named Ivona, bought by Amazon in 2013. [3] [4] It was first used in the Amazon Echo smart speaker and the Amazon Echo Dot, Echo Studio and Amazon Tap speakers developed by Amazon Lab126.

  8. Cooperative MIMO - Wikipedia

    en.wikipedia.org/wiki/Cooperative_MIMO

    In radio, cooperative multiple-input multiple-output (cooperative MIMO, CO-MIMO) is a technology that can effectively exploit the spatial domain of mobile fading channels to bring significant performance improvements to wireless communication systems. It is also called network MIMO, distributed MIMO, virtual MIMO, and virtual antenna arrays.
