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 ...

2-in-1 PC
A 2-in-1 laptop, also known as 2-in-1 PC, 2-in-1 tablet, laplet, tabtop, laptop tablet, or simply 2-in-1, is a portable computer that has features of both tablets and laptops. 2-in-1 PCs consist of portable computer components within light and thin chassis, and exemplify technological convergence. They are convenient for media consumption and non-intensive tasks in tablet mode yet useful for content production in laptop mode. Terminology Before the emergence of ''2-in-1s'' and their denomination as such, technology journalists used the words ''convertible'' and ''hybrid'' to denominate pre-2-in-1 portable computers: ''Convertible'' typically denominated those that featured a mechanism to conceal the physical keyboard by sliding or rotating it behind the chassis, and ''hybrid'' those that featured a hot-pluggable, complementary, physical keyboard. Both pre-2-in-1 convertibles and hybrids were crossover devices that combined features of both tablets and laptops. The late ...

MSM7000
MSM7000 is a series of system-on-a-chip processors manufactured by Qualcomm for handheld devices, especially smartphones. These SOCs have multiple processing cores but unlike contemporary processor chips like AMD's Athlon/Phenom and Intel's Core series, these multiple cores are not available in the OS to run applications that have symmetric multiprocessing properties. There is only one core to run the OS and user applications. Generally these SOCs have the following 4 cores: * Applications processor, ARM11, ARM1136J-S, running Windows Mobile / Android (operating system), Android / Linux / etc. * Applications DSP, QDSP5000, does coding/decoding for media. * Baseband processor, ARM9, running a real-time OS and the GSM stack * Baseband DSP, QDSP4000, does coding/decoding for telephony Apart from the CPU cores the chips contain such hardware as 2D graphics hardware, 3D (OpenGL ES 1.1) graphics hardware, media acceleration hardware (for video decode, etc.), and various interfaces (k ...

HSUPA
High Speed Packet Access (HSPA) is an amalgamation of two mobile protocols—High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA)—that extends and improves the performance of existing 3G mobile telecommunication networks using the WCDMA protocols. A further-improved 3GPP standard called Evolved High Speed Packet Access (also known as HSPA+) was released late in 2008, with subsequent worldwide adoption beginning in 2010. The newer standard allows bit rates to reach as high as 337 Mbit/s in the downlink and 34 Mbit/s in the uplink; however, these speeds are rarely achieved in practice. Overview The first HSPA specifications supported increased peak data rates of up to 14 Mbit/s in the downlink and 5.76 Mbit/s in the uplink. They also reduced latency and provided up to five times more system capacity in the downlink and up to twice as much system capacity in the uplink compared with original WCDMA protocol.

WCDMA
The Universal Mobile Telecommunications System (UMTS) is a 3G mobile cellular system for networks based on the GSM standard. UMTS uses wideband code-division multiple access (W- CDMA) radio access technology to offer greater spectral efficiency and bandwidth to mobile network operators compared to previous 2G systems like GPRS and CSD. UMTS on its provides a peak theoretical data rate of 2 Mbit/s. Developed and maintained by the 3GPP (3rd Generation Partnership Project), UMTS is a component of the International Telecommunication Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology. The technology described in UMTS is sometimes also referred to as Freedom of Mobile Multimedia Access (FOMA) or 3GSM. UMTS specifies a complete network system, which includes the radio access network ( UMTS Terrestrial Radio Access Network, or UTRAN), the core network ( Mobile Application Part, or MAP) and the authenti ...

Adreno
Adreno is a series of graphics processing unit (GPU) semiconductor intellectual property cores developed by Qualcomm and used in many of their SoCs. History Adreno is an integrated graphics processing unit (GPU) within Qualcomm's Snapdragon applications processors, that was jointly developed by ATI Technologies in conjunction with Qualcomm's preexisting "QShader" GPU architecture, and coalesced into a single family of GPUs that rebranded as Adreno in 2008, just prior to AMD's mobile division being sold to Qualcomm in January 2009 for $65M. Early Adreno models included the Adreno 100 and 110, which had 2D graphics acceleration and limited multimedia capabilities. Prior to 2008, 3D graphics on mobile platforms were commonly handled using software-based rendering engines, which limited their performance and consumed too much power to be used for anything other than rudimentary mobile graphics applications. With growing demand for more advanced multimedia and 3D graphics capabi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CDMA
Code-division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth). To permit this without undue interference between the users, CDMA employs spread spectrum technology and a special coding scheme (where each transmitter is assigned a code). CDMA optimizes the use of available bandwidth as it transmits over the entire frequency range and does not limit the user's frequency range. It is used as the access method in many mobile phone standards. IS-95, also called "cdmaOne", and its 3G evolution CDMA2000, are often simply referred to as "CDMA", but UMTS, the 3G standard used by GSM carriers, also uses "wideband CDMA", or W-CDMA, as well as TD-CDMA and TD-SCDMA, as its radio technologies. Many carriers (such as AT&T, U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semiconductor Device Fabrication
Semiconductor device fabrication is the process used to manufacture semiconductor devices, typically integrated circuits (ICs) such as microprocessors, microcontrollers, and memories (such as Random-access memory, RAM and flash memory). It is a multiple-step Photolithography, photolithographic and physico-chemical process (with steps such as thermal oxidation, thin-film deposition, ion-implantation, etching) during which electronic circuits are gradually created on a wafer (electronics), wafer, typically made of pure single-crystal semiconducting material. Silicon is almost always used, but various compound semiconductors are used for specialized applications. This article focuses on the manufacture of integrated circuits, however steps such as etching and photolithography can be used to manufacture other devices such as LCD and OLED displays. The fabrication process is performed in highly specialized semiconductor fabrication plants, also called foundries or "fabs", with the cen ...

Smartbook
A smartbook was a class of mobile device that combined certain features of both a smartphone and netbook computer, produced between 2009 and 2010. Smartbooks were advertised with features such as wiktionary:always-on, always on, all-day battery life, 3G, or Wi-Fi connectivity and GPS (all typically found in smartphones) in a laptop or tablet-style body with a screen size of 5 to 10 inches and a physical or soft touchscreen keyboard. A German company sold laptops under the brand ''Smartbook'' and held a trademark for the word in many countries (not including some big markets like United States, China, Japan, or India). It acted to preempt others from using the term ''smartbook'' to describe their products. Smartbooks tended to be designed more for entertainment purposes than for productivity and typically targeted to work with online applications. They were projected to be sold subsidized through mobile network operators, like mobile phones, along with a wireless data plan. Th ...

Smartwatch
A smartwatch is a portable wearable computer that resembles a wristwatch. Most modern smartwatches are operated via a touchscreen, and rely on mobile apps that run on a connected device (such as a smartphone) in order to provide core functions. Early smartwatches were capable of performing basic functions like calculator watch, calculating, displaying digital time, translating text, and playing games. More recent models often offer features comparable to smartphones, including apps, a mobile operating system, Bluetooth and Wi-Fi connectivity, and the ability to function as portable media players or FM broadcasting, FM radios. Some high-end models have cellular capabilities, allowing users to make and receive phone calls. While internal hardware varies, most smartwatches have a backlit Liquid-crystal display, LCD or OLED electronic visual display and are powered by a rechargeable lithium-ion battery. They may also incorporate GPS navigation device, GPS receivers, digital cameras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
