In radio, multiple-input and multiple-output (MIMO) is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation. MIMO has become an essential element of wireless communication standards including IEEE 802.11n, IEEE 802.11ac, HSPA+ (3G), WiMAX, and Long Term Evolution (LTE). More recently, MIMO has been applied to power-line communication for three-wire installations as part of the ITU G.hn standard and of the HomePlug AV2 specification.
Snapdragon is a suite of system-on-a-chip (SoC) semiconductor products for mobile devices designed and marketed by Qualcomm Technologies Inc. The Snapdragon's central processing unit (CPU) uses the ARM architecture. As such, Qualcomm often refers to the Snapdragon as a "mobile platform". Snapdragon semiconductors are embedded in devices of various systems, including vehicles, Android, Windows Phone and netbooks. In addition to the processors, the Snapdragon line includes modems, Wi-Fi chips and mobile charging products.

Linksys manufactures a series of network routers. Many models are shipped with Linux-based firmware and can run third-party firmware. The first model to support third-party firmware was the very popular Linksys WRT54G series.
Wilocity was a fabless semiconductor company based in California founded in 2007 developing 60 GHz multi-gigabit wireless chipsets for both the mobile computing platform and peripheral markets. Wilocity was founded in March 2007 by executives and engineers from Intel's Wi-Fi Centrino group. While Wilocity is based in California, most of its employees are in Israel. Based on the WiGig specification, Wilocity's Wireless PCI Express (wPCIe) technology enables multi-gigabit wireless for applications including I/O, networking and video.
IEEE 802.11ac-2013 or 802.11ac is a wireless networking standard in the IEEE 802.11 set of protocols, providing high-throughput wireless local area networks (WLANs) on the 5 GHz band. The standard has been retroactively labelled as Wi-Fi 5 by Wi-Fi Alliance.
Redpine Signals was a fabless semiconductor company founded in 2001. The company made chipsets and system-level products for wireless networks. It served the Internet of Things and wireless embedded systems market, enabling all volume levels of chipsets and modules.
PowerCloud Systems was a cloud networking company located in Palo Alto, California. The company designed and manufactured cloud-powered Wi-Fi systems for businesses, carriers and consumers and was a corporate spin-off from the Palo Alto Research Center (PARC), a Xerox company. PowerCloud was purchased by Comcast in July 2014.
The first smart antennas were developed for military communications and intelligence gathering. The growth of cellular telephone in the 1980s attracted interest in commercial applications. The upgrade to digital radio technology in the mobile phone, indoor wireless network, and satellite broadcasting industries created new opportunities for smart antennas in the 1990s, culminating in the development of the MIMO technology used in 4G wireless networks.
Gregory “Greg” Raleigh, is an American radio scientist, inventor, and entrepreneur who has made contributions in the fields of wireless communication, information theory, mobile operating systems, medical devices, and network virtualization. His discoveries and inventions include the first wireless communication channel model to accurately predict the performance of advanced antenna systems, the MIMO-OFDM technology used in contemporary Wi-Fi and 4G wireless networks and devices, higher accuracy radiation beam therapy for cancer treatment, improved 3D surgery imaging, and a cloud-based Network Functions Virtualization platform for mobile network operators that enables users to customize and modify their smartphone services.
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 (MIMO) technology, which multiplies capacity by transmitting different signals over multiple antennas, and orthogonal frequency-division multiplexing (OFDM), which divides a radio channel into a large number of closely spaced subchannels to provide more reliable communications at high speeds. Research conducted during the mid-1990s showed that while MIMO can be used with other popular air interfaces such as time-division multiple access (TDMA) and code-division multiple access (CDMA), the combination of MIMO and OFDM is most practical at higher data rates.
Wi-Fi 6, or IEEE 802.11ax, is an IEEE standard from the Wi-Fi Alliance, for wireless networks (WLANs). It operates in the 2.4 GHz and 5 GHz bands, with an extended version, Wi-Fi 6E, that adds the 6 GHz band. It is an upgrade from Wi-Fi 5 (802.11ac), with improvements for better performance in crowded places. Wi-Fi 6 covers frequencies in license-exempt bands between 1 and 7.125 GHz, including the commonly used 2.4 GHz and 5 GHz, as well as the broader 6 GHz band.
