Atheros
Atheros Communications, Inc., was an American computer networking company independently active from 1998 to 2011. It produced semiconductor chips for network communications, particularly wireless chipsets. The company was founded under the name T-Span Systems in 1998 by experts in signal processing and VLSI design from Stanford University, the University of California, Berkeley, and private industry. The company was renamed Atheros Communications in 2000 and it completed an initial public offering in February 2004, trading on the NASDAQ under the symbol ATHR. On January 5, 2011, it was announced that Qualcomm had agreed to a takeover of the company for a valuation of US$3.7 billion. When the acquisition was completed on May 24, 2011, Atheros became a subsidiary of Qualcomm operating under the name Qualcomm Atheros. Qualcomm Atheros chipsets for the IEEE 802.11 standard of wireless networking are used by over 30 different wireless device manufacturers. History T-Span Systems ...

Super G (wireless Networking)
Super G is a proprietary method to increase the throughput of an IEEE 802.11g (Wi-Fi) wireless LAN. Atheros uses frame-bursting, compression, and channel bonding technology to improve performance. The throughput transmission speed limit when using Super G is claimed to be up to 40 Mbit/s-60 Mbit/s at a 108 Mbit/s signaling rate, which is achieved through the bonding of two 54 Mbit/s 802.11g channels. Vendors Other vendors have marketed Super G products as 108G Technology, 108 Mbit/s 802.11g, Xpress technology and Xtreme G. Manufacturers that have licensed Super G technology from Atheros include Airlink 101, Clipsal, D-Link, Intelbras, LevelOne, Netgear, Nortel Networks, Planex, SMC, Sony, TRENDnet, SparkLAN, Toshiba and ZyXEL. In general, Super G products from different vendors are all interoperable in Super G mode. Interference Non-standard channel bonding extensions to 802.11g such as Super G, have been criticized for creating interference ...

HomePlug
HomePlug is the family name for various power line communications specifications under the HomePlug designation, each with unique capabilities and compatibility with other HomePlug specifications. Some HomePlug specifications target broadband applications. For instance in-home distribution of low data rate IPTV, gaming, and Internet content, while others focus on low power, low throughput and extended operating temperatures for applications such as smart power meters and in-home communications between electric systems and appliances. All of the HomePlug specifications were developed by the HomePlug Powerline Alliance, which also owns the HomePlug trademark. On 18 October 2016 the HomePlug Alliance announced that all of its specifications would be put into the public domain and that other organizations would be taking on future activities relating to deployment of the existing technologies. There was no mention in the announcement of any further technology development within the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qualcomm
Qualcomm Incorporated () is an American multinational corporation headquartered in San Diego, California, and Delaware General Corporation Law, incorporated in Delaware. It creates semiconductors, software and services related to wireless technology. It owns patents critical to the 5G, 4G, CDMA2000, TD-SCDMA and WCDMA mobile communications standards. Qualcomm was established in 1985 by Irwin M. Jacobs, Irwin Jacobs and six other co-founders. Its early research into CDMA wireless cell phone technology was funded by selling a two-way mobile digital satellite communications system known as Omnitracs. After a heated debate in the wireless industry, CDMA was adopted as a 2G standard in North America, with Qualcomm's patents incorporated. Afterwards, there was a series of legal disputes about pricing for licensing patents required by the standard. Over the years, Qualcomm has expanded into selling semiconductor products in a predominantly fabless manufacturing model. It also develope ...

CMOS
Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss ", , ) is a type of MOSFET, metal–oxide–semiconductor field-effect transistor (MOSFET) semiconductor device fabrication, fabrication process that uses complementary and symmetrical pairs of p-type semiconductor, p-type and n-type semiconductor, n-type MOSFETs for logic functions. CMOS technology is used for constructing integrated circuit (IC) chips, including microprocessors, microcontrollers, memory chips (including Nonvolatile BIOS memory, CMOS BIOS), and other digital logic circuits. CMOS technology is also used for analog circuits such as image sensors (CMOS sensors), data conversion, data converters, RF circuits (RF CMOS), and highly integrated transceivers for many types of communication. In 1948, Bardeen and Brattain patented an insulated-gate transistor (IGFET) with an inversion layer. Bardeen's concept forms the basis of CMOS technology today. The CMOS process was presented by Fairchild Semico ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qualcomm Snapdragon
Snapdragon is a suite of system-on-chip (SoC) semiconductor products for mobile devices designed and marketed by Qualcomm, who often refers to these SoCs as "mobile platforms". They typically integrate central processing units (CPU) based on the ARM architecture, a graphics processing unit (GPU), some digital signal processors (DSP), and may or may not include a cellular modem. Snapdragon semiconductors are designed for embedded systems, e.g., smartphones, netbooks, and vehicles. In addition to the processors, the lineup also includes modems, Wi-Fi chips and mobile charging products. The first Snapdragon-branded product was released in December 2007, using CPU based on Qualcomm’s “Scorpion” microarchitecture. The architecture’s successor, “Krait”, was introduced in 2011 and featured asynchronous symmetrical multi-processing: cores can adjust their clock speed and voltage independent of each other. On the announcement of Snapdragon 800 in 2013 Consumer E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bluetooth
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to . It employs Ultra high frequency, UHF radio waves in the ISM bands, from 2.402GHz to 2.48GHz. It is mainly used as an alternative to wired connections to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones, wireless speakers, HIFI systems, car audio and wireless transmission between TVs and soundbars. Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics.

Integrated Circuit
An integrated circuit (IC), also known as a microchip or simply chip, is a set of electronic circuits, consisting of various electronic components (such as transistors, resistors, and capacitors) and their interconnections. These components are etched onto a small, flat piece ("chip") of semiconductor material, usually silicon. Integrated circuits are used in a wide range of electronic devices, including computers, smartphones, and televisions, to perform various functions such as processing and storing information. They have greatly impacted the field of electronics by enabling device miniaturization and enhanced functionality. Integrated circuits are orders of magnitude smaller, faster, and less expensive than those constructed of discrete components, allowing a large transistor count. The IC's mass production capability, reliability, and building-block approach to integrated circuit design have ensured the rapid adoption of standardized ICs in place of designs using discre ...
