Nokia Lumia 2520
The Nokia Lumia 2520 is a Windows RT tablet computer originally developed by Nokia. It is Nokia's first and only Windows-based tablet, and the company's first tablet since its Nokia Internet Tablet line. Sharing its design and marketed with the Nokia Lumia series of Windows Phone products, the device incorporates a quad-core Snapdragon 800 chip with 4G LTE support, along with a 10.1-inch (26 cm) 1080p display and an optional "Power Keyboard" dock adding additional battery capacity, USB ports, and a physical hardware keyboard. Following a period of speculation and leaks, the Lumia 2520 was officially unveiled on 22 October 2013, and released in North America on 21 November 2013. The 2520 was met with mostly positive reviews, praising its design, display, and for being the first Windows RT tablet to offer cellular data (although Microsoft's own Surface 2 was soon available with such an option). However, the device also received criticism for the lack of available software for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bluetooth V4
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 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. The IEEE standardized Bluetooth as IEEE 802.15.1 but no longer maintains the standard. The Bluetooth SIG oversees the development of the specific ...

1080p
1080p (1920 × 1080 progressively displayed pixels; also known as Full HD or FHD, and BT.709) is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the ''p'' stands for progressive scan, ''i.e.'' non- interlaced. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 2.1 megapixels. It is often marketed as Full HD or FHD, to contrast 1080p with 720p resolution screens. Although 1080p is sometimes referred to as 2K resolution (meaning having a horizontal resolution of approximately 2,000 pixels), other sources differentiate between 1080p and (true) 2K resolution. 1080p video signals are supported by ATSC standards in the United States and DVB standards in Europe. Applications of the 1080p standard include television broadcasts, Blu-ray Discs, smartphones, Internet content such as YouTube videos and Netflix TV shows and movi ...

LTE (telecommunication)
In telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for cellular mobile devices and data terminals. It is considered to be a "transitional" 4G technology, and is therefore also referred to as 3.95G as a step above 3G. LTE is based on the 2G GSM/ EDGE and 3G UMTS/ HSPA standards. It improves on those standards' capacity and speed by using a different radio interface and core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. LTE has been succeeded by LTE Advanced, which is officially defined as a "true" 4G technology and also named "LTE+". Terminology The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. LTE is also called 3.95G and has been marketed as 4G LTE and Advanced 4G; but the original version did not meet the technical criteria of a 4G wire ...

Windows Phone
Windows Phone (WP) is a discontinued mobile operating system developed by Microsoft Mobile for smartphones as the replacement successor to Windows Mobile and Zune. Windows Phone featured a new user interface derived from the Metro design language. Unlike Windows Mobile, it was primarily aimed at the consumer market rather than the enterprise software, enterprise market. It was first launched in October 2010 with Windows Phone 7. Windows Phone 8 succeeded it in 2012, replacing the Windows CE-based kernel of Windows Phone 7 with the Windows NT kernel used by the PC versions of Microsoft Windows, Windows (and, in particular, a large amount of internal components from Windows 8). Due to these changes, the OS was incompatible with all existing Windows Phone 7 devices, although it still supported apps originally developed for Windows Phone 7. In 2014, Microsoft released the Windows Phone 8.1 update, which introduced the Cortana (virtual assistant), Cortana virtual assistant, and Window ...

Nokia Lumia
Nokia Lumia, later rebranded to Microsoft Lumia, is a discontinued line of mobile devices that was originally designed and marketed by Nokia and later by Microsoft Mobile. Introduced on October 26, 2011, the line was the result of a long-term partnership between Nokia and Microsoft—as such, Lumia smartphones run on Microsoft software, the Windows Phone operating system; and later the newer Windows 10 Mobile. The Lumia name is derived from the partitive plural form of the Finnish word ''lumi'', meaning "snow". The series debuted with the Nokia Lumia 800 and the Lumia 710 smartphones. In April 2012, the first high-end flagship, Nokia Lumia 900, was released in the US in partnership with AT&T, backed by a major marketing push. Its later flagships included the Nokia Lumia 920, 925, and the first phablet-style model, Nokia Lumia 1520. However, its most successful model was in the lower-end, the budget Nokia Lumia 520, released in April 2013. In July 2013, Nokia introduced ...

Nokia Internet Tablet
Nokia Internet Tablets is the name given to a range of Nokia mobile Internet appliances products. These tablets fall in the range between a personal digital assistant (PDA) and an Ultra-Mobile PC (UMPC), and slightly below Intel's Mobile Internet device (MID). Early trials and predecessors Nokia had plans for an Internet tablet since before 2000. An early model was test manufactured in 2001, the Nokia M510, which was running on EPOC and featuring an Opera browser, speakers and a 10-inch 800x600 screen, but it was not released because of fears that the market was not ready for it. The M510 was first leaked to the public in 2014. Prior to the introduction of Nokia's Internet tablets, Nokia unveiled two "media devices" in 2003-04 which were mobile phones but had a form factor similar to the Internet tablets that followed them. The first of this type of device was the Nokia 7700 which was intended for mass production but ended up being canned in favor of the Nokia 7710 which had ...

Tablet Computer
A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, have similar capabilities, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens or larger, measured diagonally, and may not support access to a cellular network. Unlike laptops (which have traditionally run off operating systems usually designed for desktops), tablets usually run mobile operating systems, alongside smartphones. The touchscreen display is operated by Gesture recognition, gestures executed by finger or digital pen (stylus), instead of the Computer mouse, mouse, touchpad, and Keyboard (computing), keyboard of larger computers. Portable computers can be classified according ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsoft Surface 3
Surface 3 is a 2-in-1 detachable from the Microsoft Surface series, introduced by Microsoft in 2015. Unlike its predecessor, the Surface 2, Surface 3 utilizes an x86 Intel Atom system-on-chip architecture, or SoC, rather than a processor with ARM architecture such as the Nvidia Tegra that powered the Surface 2, and runs standard versions of Windows 8.1 or Windows 10. History The older, original Surface (also known as Surface RT) and Surface 2, with their ARM-based processors and Windows RT operating system, were designed to compete with the iPad and other tablets. The first Surface was criticized for performance issues, which were reduced in the succeeding Surface 2. Due to the differing processors, these devices were incompatible with the vast number of Windows programs written for x86-based computers, running only those written and compiled for Windows RT, loaded from Microsoft's application store. Released prior to Surface 3, the Surface Pro 3 – featuring a more power ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nokia N1
The Nokia N1 is a tablet developed by Nokia, running on Android 5.0. Unveiled on 18 November 2014, it is Nokia's first mobile device since the sale of its original mobile phone business to Microsoft earlier in the year. It was released in January 2015. Development According to Sebastian Nyström, Head of Products Business Nokia Technologies, work on the tablet began on 28 April just days after the acquisition of its former mobile phone division by Microsoft.

IEEE 802
IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks (LANs), personal area networks (PANs), and metropolitan area networks (MANs). The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards. The IEEE 802 family of standards has had twenty-four members, numbered 802.1 through 802.24, with a working group of the LMSC devoted to each. However, not all of these working groups are currently active. The IEEE 802 standards are restricted to computer networks carrying variable-size packets, unlike cell relay networks, for example, in which data is transmitted in short, uniformly sized units called cells. Isochronous signal networks, in which data is transmitted as a steady stream of octet (computing), octets, or groups of octets, at regular time intervals, are also outside the scope of the IEEE 802 standards. The number 802 has no significance: it was simply the next number in the sequence that the IEEE used fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
