107-581: The Asus Transformer Pad TF300T is a tablet computer with a LED 10.1" IPS 10-finger multi-touch screen with a resolution of 1280x800. This display is not Super IPS+ contrary to the ASUS Eee Pad Transformer Prime . The unit does not employ Gorilla Glass, and is therefore more susceptible to breakage. The processor is an Nvidia Tegra 3 T30L at 1.2 GHz upon initial release with Android 4.0.X ICS, but overclocked to 1.3 GHz upon updating to Android 4.1 Jelly Bean (latest firmware

214-599: A Mac OS X -based tablet computer. The Modbook uses Apple's Inkwell for handwriting and gesture recognition, and uses digitization hardware from Wacom . To get Mac OS X to talk to the digitizer on the integrated tablet, the Modbook was supplied with a third-party driver. Following the launch of the Ultra-mobile PC , Intel began the Mobile Internet Device initiative, which took the same hardware and combined it with

321-411: 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 gestures executed by finger or digital pen (stylus), instead of the mouse , touchpad , and keyboard of larger computers. Portable computers can be classified according to

428-455: A local area network (LAN). Tablets, like conventional PCs, use several different operating systems , though dual-booting is rare. Tablet operating systems come in two classes: Desktop OS-based tablets are currently thicker and heavier. They require more storage and more cooling and give less battery life. They can run processor-intensive graphical applications in addition to mobile apps , and have more ports . Mobile-based tablets are

535-411: 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 7 inches (18 cm) or larger, measured diagonally, and may not support access to

642-492: A round-robin fashion. Since it is the master that chooses which slave to address, whereas a slave is (in theory) supposed to listen in each receive slot, being a master is a lighter burden than being a slave. Being a master of seven slaves is possible; being a slave of more than one master is possible. The specification is vague as to required behavior in scatternets. Bluetooth is a standard wire-replacement communications protocol primarily designed for low power consumption, with

749-461: A 7-inch display while Vega's was 15 inches. Many more products followed in 2010. Several manufacturers waited for Android Honeycomb , specifically adapted for use with tablets, which debuted in February 2011. Apple is often credited for defining a new class of consumer device with the iPad , which shaped the commercial market for tablets in the following years, and was the most successful tablet at

856-409: A Bluetooth device. A network of patents applies to the technology, which is licensed to individual qualifying devices. As of 2021 , 4.7 billion Bluetooth integrated circuit chips are shipped annually. Bluetooth was first demonstrated in space in 2024, an early test envisioned to enhance IoT capabilities. The name "Bluetooth" was proposed in 1997 by Jim Kardach of Intel , one of the founders of

963-446: A Debian-based Linux distribution custom-made for their Internet tablet line. The user interface and application framework layer, named Hildon , was an early instance of a software platform for generic computing in a tablet device intended for internet consumption. But Nokia did not commit to it as their only platform for their future mobile devices and the project competed against other in-house platforms and later replaced it with

1070-782: A built-in Bluetooth radio, others require an external adapter, typically in the form of a small USB " dongle ". Unlike its predecessor, IrDA , which requires a separate adapter for each device, Bluetooth lets multiple devices communicate with a computer over a single adapter. For Microsoft platforms, Windows XP Service Pack 2 and SP3 releases work natively with Bluetooth v1.1, v2.0 and v2.0+EDR. Previous versions required users to install their Bluetooth adapter's own drivers, which were not directly supported by Microsoft. Microsoft's own Bluetooth dongles (packaged with their Bluetooth computer devices) have no external drivers and thus require at least Windows XP Service Pack 2. Windows Vista RTM/SP1 with

1177-465: A cellular phone and a vehicle's audio system. At the time, Sony/Ericsson had only a minor market share in the cellular phone market, which was dominated in the US by Nokia and Motorola. Due to ongoing negotiations for an intended licensing agreement with Motorola beginning in the late 1990s, Vosi could not publicly disclose the intention, integration, and initial development of other enabled devices which were to be

1391-621: A given link depends on several qualities of both communicating devices and the air and obstacles in between . The primary attributes affecting range are the data rate, protocol (Bluetooth Classic or Bluetooth Low Energy), transmission power, and receiver sensitivity, and the relative orientations and gains of both antennas. The effective range varies depending on propagation conditions, material coverage, production sample variations, antenna configurations and battery conditions. Most Bluetooth applications are for indoor conditions, where attenuation of walls and signal fading due to signal reflections make

1498-415: A hardware and software perspective, and delivered in a business-to-business transaction. For example, in hardware, a transportation company may find that the consumer-grade GPS module in an off-the-shelf tablet provides insufficient accuracy, so a tablet can be customized and embedded with a professional-grade antenna to provide a better GPS signal. Such tablets may also be ruggedized for field use. For

1605-488: A keyboard and stylus, which reflected the changing uses. As of early 2016, Android reigned over the market with 65%. Apple took the number 2 spot with 26%, and Windows took a distant third with the remaining 9%. In 2018, out of 4.4 billion computing devices Android accounted for 2 billion, iOS for 1 billion, and the remainder were PCs, in various forms (desktop, notebook, or tablet), running various operating systems (Windows, macOS, ChromeOS, Linux, etc.). Since

1712-479: A keyboard or mouse. This operation makes precise use of our eye–hand coordination . Touchscreens usually come in one of two forms: Since mid-2010s, most tablets use capacitive touchscreens with multi-touch , unlike earlier resistive touchscreen devices which users needed styluses to perform inputs. There are also electronic paper tablets such as Sony Digital Paper DPTS1 and reMarkable that use E ink for its display technology. Many tablets support

1819-486: A large product category used for personal, educational and workplace applications. Popular uses for a tablet PC include viewing presentations, video-conferencing, reading e-books, watching movies, sharing photos and more. As of 2021 there are 1.28 billion tablet users worldwide according to data provided by Statista , while Apple holds the largest manufacturer market share followed by Samsung and Lenovo . The tablet computer and its associated operating system began with

1926-469: A lower power consumption through a reduced duty cycle . The specification is published as Bluetooth v2.0 + EDR , which implies that EDR is an optional feature. Aside from EDR, the v2.0 specification contains other minor improvements, and products may claim compliance to "Bluetooth v2.0" without supporting the higher data rate. At least one commercial device states "Bluetooth v2.0 without EDR" on its data sheet. Bluetooth Core Specification version 2.1 + EDR

2033-410: A membership of over 30,000 companies worldwide. It was established by Ericsson , IBM , Intel , Nokia and Toshiba , and later joined by many other companies. All versions of the Bluetooth standards are backward-compatible with all earlier versions. The Bluetooth Core Specification Working Group (CSWG) produces mainly four kinds of specifications: Major enhancements include: This version of

2140-570: A mobile operating system such as Android have incorporated modern functionally including internet browsing and multimedia capabilities; for example Huawei MatePad Paper is a tablet that uses e-ink instead of typical LCD or LED panel, hence focusing on the reading digital content while maintaining the internet and multimedia capabilities. Some E-reader such as PocketBook InkPad Color and ONYX BOOX NOVA 3 Color even came with colored e-ink panel and speaker which allowed for higher degree of multimedia consumption and video playback. The Kindle line from Amazon

2247-511: A more significant approach to tablets in 2002 as it attempted to define the Microsoft Tablet PC as a mobile computer for field work in business, though their devices failed, mainly due to pricing and usability decisions that limited them to their original purpose – such as the existing devices being too heavy to be held with one hand for extended periods, and having legacy applications created for desktop interfaces and not well adapted to

2354-475: A radio technology called frequency-hopping spread spectrum . Bluetooth divides transmitted data into packets, and transmits each packet on one of 79 designated Bluetooth channels. Each channel has a bandwidth of 1   MHz. It usually performs 1600   hops per second, with adaptive frequency-hopping (AFH) enabled. Bluetooth Low Energy uses 2   MHz spacing, which accommodates 40 channels. Originally, Gaussian frequency-shift keying (GFSK) modulation

2461-419: A short range based on low-cost transceiver microchips in each device. Because the devices use a radio (broadcast) communications system, they do not have to be in visual line of sight of each other; however, a quasi optical wireless path must be viable. Historically, the Bluetooth range was defined by the radio class, with a lower class (and higher output power) having larger range. The actual range of

2568-719: A software example, the same transportation company might remove certain software functions in the Android system, such as the internet browser, to reduce costs from needless cellular network data consumption of an employee, and add custom package management software. Other applications may call for a resistive touchscreen and other special hardware and software. A table ordering tablet is a touchscreen tablet computer designed for use in casual restaurants . Such devices allow users to order food and drinks, play games and pay their bill. Since 2013, restaurant chains including Chili's , Olive Garden and Red Robin have adopted them. As of 2014,

2675-429: A stylus and support handwriting recognition . Wacom and N-trig digital pens provide approximately 2500 DPI resolution for handwriting, exceeding the resolution of capacitive touch screens by more than a factor of 10. These pens also support pressure sensitivity, allowing for "variable-width stroke-based" characters, such as Chinese/Japanese/Korean writing, due to their built-in capability of "pressure sensing". Pressure

2782-654: A tabletized Linux configuration. Intel codeveloped the lightweight Moblin (mobile Linux) operating system following the successful launch of the Atom CPU series on netbooks. In 2010, Nokia and Intel combined the Maemo and Moblin projects to form MeeGo, a Linux-based operating system supports netbooks and tablets. The first tablet using MeeGo was the Neofonie WeTab launched September 2010 in Germany. The WeTab used an extended version of

2889-665: A variant with 4G LTE support for AT&T, T-Mobile, and Verizon. In September 2013, Amazon further updated the Fire tablet with the Kindle Fire HDX . In November 2013, Apple released the iPad Mini 2 , which remained at 7.9 inches and nearly matched the hardware of the iPad Air . Smartphones and tablets are similar devices, differentiated by the former typically having smaller screens and most tablets lacking cellular network capability. Since 2010, crossover touchscreen smartphones with screens larger than 5 inches have been released. That size

A key component among tablet computers

6206-486: The codename for the short-range wireless program which is now called Bluetooth. According to Bluetooth's official website, Bluetooth was only intended as a placeholder until marketing could come up with something really cool. Later, when it came time to select a serious name, Bluetooth was to be replaced with either RadioWire or PAN (Personal Area Networking). PAN was the front runner, but an exhaustive search discovered it already had tens of thousands of hits throughout

6313-529: The communication from the start. Adherence to profiles saves the time for transmitting the parameters anew before the bi-directional link becomes effective. There are a wide range of Bluetooth profiles that describe many different types of applications or use cases for devices. Bluetooth exists in numerous products such as telephones, speakers , tablets, media players, robotics systems, laptops, and game console equipment as well as some high definition headsets , modems , hearing aids and even watches.

An LTE model supporting the above cellular standards as well as LTE has been released as the TF300TL. CyanogenMod 11 or later, an unofficial updated version of Android can be installed onto the TF300T tablet. In addition, the TF300 continues to be supported by an active community of aftermarket operating system developers at XDA Developers several years after its initial release. The Verge noted

7597-409: The larger Google Play system, thereby fragmenting the Android market. In 2022 Google began to re-emphasize in-house Android tablet development — at this point, a multi-year commitment. 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

7704-471: The most widely used mode, transmission power is limited to 2.5 milliwatts , giving it a very short range of up to 10 metres (33 ft). It employs UHF radio waves in the ISM bands , from 2.402   GHz to 2.48   GHz. 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 . Bluetooth

7811-497: The option of connecting a conventional Keyboard and mouse. Intel announced a StrongARM processor-based touchscreen tablet computer in 1999, under the name WebPAD. It was later re-branded as the "Intel Web Tablet". In 2000, Norwegian company Screen Media AS and the German company Dosch & Amand Gmbh released the "FreePad". It was based on Linux and used the Opera browser . Internet access

7918-442: The presence and appearance of physical keyboards. Two species of tablet, the slate and booklet , do not have physical keyboards and usually accept text and other input by use of a virtual keyboard shown on their touchscreen displays. To compensate for their lack of a physical keyboard, most tablets can connect to independent physical keyboards by Bluetooth or USB ; 2-in-1 PCs have keyboards, distinct from tablets. The form of

8025-661: The public market due to its large market share at the time. In 2012, Jaap Haartsen was nominated by the European Patent Office for the European Inventor Award . Bluetooth operates at frequencies between 2.402 and 2.480   GHz, or 2.400 and 2.4835   GHz, including guard bands 2   MHz wide at the bottom end and 3.5   MHz wide at the top. This is in the globally unlicensed (but not unregulated) industrial, scientific and medical ( ISM ) 2.4   GHz short-range radio frequency band. Bluetooth uses

8132-413: The range far lower than specified line-of-sight ranges of the Bluetooth products. Most Bluetooth applications are battery-powered Class 2 devices, with little difference in range whether the other end of the link is a Class 1 or Class 2 device as the lower-powered device tends to set the range limit. In some cases the effective range of the data link can be extended when a Class 2 device

8239-542: The release of the mobile-focused and comparatively power-efficient 32-bit ARM610 processor originally designed for the Apple Newton in 1993 and ARM3-using Acorn A4 laptop in 1992. The chip was adopted by Psion, Palm and Nokia for PDAs and later smartphones, camera phones, cameras, etc. ARM's licensing model supported this success by allowing device manufacturers to license, alter and fabricate custom SoC derivatives tailored to their own products. This has helped manufacturers extend battery life and shrink component count along with

8346-599: The reverse, and run only mobile apps. They can use battery life conservatively because the processor is significantly smaller. This allows the battery to last much longer than the common laptop. In Q1 2018, Android tablets had 62% of the market, Apple's iOS had 23.4% of the market and Windows 10 had 14.6% of the market. In late 2021, iOS has 55% use worldwide (varies by continent, e.g. below 50% in South America and Africa) and Android 45% use. Still, Android tablets have more use than iOS in virtually all countries, except for e.g.

8453-427: The same spectrum but somewhat differently . A master BR/EDR Bluetooth device can communicate with a maximum of seven devices in a piconet (an ad hoc computer network using Bluetooth technology), though not all devices reach this maximum. The devices can switch roles, by agreement, and the slave can become the master (for example, a headset initiating a connection to a phone necessarily begins as master—as an initiator of

8560-590: The screen in multiple places to trigger actions and other natural user interface features, as well as flash memory solid state storage and "instant on" warm-booting ; external USB and Bluetooth keyboards defined tablets. Most tablets released since mid-2010 use a version of an ARM processor for longer battery life. The ARM Cortex family is powerful enough for tasks such as internet browsing , light creative and production work and mobile games . Other features are: High-definition, anti-glare display , touchscreen, lower weight and longer battery life than

8667-449: The services they provide. This makes using services easier, because more of the security, network address and permission configuration can be automated than with many other network types. A personal computer that does not have embedded Bluetooth can use a Bluetooth adapter that enables the PC to communicate with Bluetooth devices. While some desktop computers and most recent laptops come with

8774-404: The short-link technology an open industry standard to permit each player maximum market access. Ericsson contributed the short-link radio technology, and IBM contributed patents around the logical layer. Adalio Sanchez of IBM then recruited Stephen Nachtsheim of Intel to join and then Intel also recruited Toshiba and Nokia . In May 1998, the Bluetooth SIG was launched with IBM and Ericsson as

8881-401: The simple case of single-slot packets, the master transmits in even slots and receives in odd slots. The slave, conversely, receives in even slots and transmits in odd slots. Packets may be 1, 3, or 5 slots long, but in all cases, the master's transmission begins in even slots and the slave's in odd slots. The above excludes Bluetooth Low Energy, introduced in the 4.0 specification, which uses

8988-405: The size of devices. The multiple licensees ensured that multiple fabricators could supply near-identical products, while encouraging price competition. This forced unit prices down to a fraction of their x86 equivalents. The architecture has historically had limited support from Microsoft, with only Windows CE available, but with the 2012 release of Windows 8, Microsoft announced added support for

9095-550: The slate format. 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 800×600 screen, but it was not released because of fears that the market was not ready for it. Nokia entered the tablet space in May 2005 with the Nokia 770 running Maemo ,

9202-468: The tablet market, ARM Ltd. 's ARM architecture and Intel's and AMD's x86 . Intel's x86, including x86-64 has powered the "IBM compatible" PC since 1981 and Apple's Macintosh computers since 2006. The CPUs have been incorporated into tablet PCs over the years and generally offer greater performance along with the ability to run full versions of Microsoft Windows , along with Windows desktop and enterprise applications. Non-Windows based x86 tablets include

9309-402: The tablet was conceptualized in the middle of the 20th century ( Stanley Kubrick depicted fictional tablets in the 1968 science fiction film 2001: A Space Odyssey ) and prototyped and developed in the last two decades of that century. In 2010, Apple released the iPad , the first mass-market tablet to achieve widespread popularity. Thereafter, tablets rapidly rose in ubiquity and soon became

9416-402: The team had a workable solution. From 1997 Örjan Johansson became the project leader and propelled the technology and standardization. In 1997, Adalio Sanchez, then head of IBM ThinkPad product R&D, approached Nils Rydbeck about collaborating on integrating a mobile phone into a ThinkPad notebook. The two assigned engineers from Ericsson and IBM studied the idea. The conclusion

9523-477: The time of its release. iPads and competing devices were tested by the U.S. military in 2011 and cleared for secure use in 2013. Its debut in 2010 pushed tablets into the mainstream. Samsung 's Galaxy Tab and others followed, continuing the trends towards the features listed above. In March 2012, PC Magazine reported that 31% of U.S. Internet users owned a tablet, used mainly for viewing published content such as video and news. The top-selling line of devices

9630-936: The touchscreen ("2-in-1 convertible") or detachable ("2-in-1 detachable"). 2-in-1s typically also can display a virtual keyboard on their touchscreens when their physical keyboards are concealed or detached. Some 2-in-1s have processors and operating systems like those of laptops, such as Windows 10 , while having the flexibility of operation as a tablet. Further, 2-in-1s may have typical laptop I/O ports, such as USB 3 and DisplayPort , and may connect to traditional PC peripheral devices and external displays. Simple tablets are mainly used as media consumption devices, while 2-in-1s have capacity for both media consumption and content creation , and thus 2-in-1s are often called laptop or desktop replacement computers . There are two species of 2-in-1s: Some tablets are modified by adding physical gamepad buttons such as D-pad and thumb sticks for better gaming experience combined with

9737-424: The two most popular brands were Ziosk and Presto . The devices have been criticized by servers who claim that some restaurants determine their hours based on customer feedback in areas unrelated to service. Any device that can display text on a screen may act as an E-reader . While traditionally E-readers are designed primarily for the purpose of reading digital e-books and periodicals, modern E-readers that use

9844-583: Was Apple's iPad with 100 million sold between its release in April 2010 and mid-October 2012, but iPad market share (number of units) dropped to 36% in 2013 with Android tablets climbing to 62%. Android tablet sales volume was 121 million devices, plus 52 million, between 2012 and 2013 respectively. Individual brands of Android operating system devices or compatibles follow iPad with Amazon's Kindle Fire with 7 million, and Barnes & Noble's Nook with 5 million. The BlackBerry PlayBook

9951-473: Was adopted by the Bluetooth SIG on 26 July 2007. The headline feature of v2.1 is secure simple pairing (SSP): this improves the pairing experience for Bluetooth devices, while increasing the use and strength of security. Version 2.1 allows various other improvements, including extended inquiry response (EIR), which provides more information during the inquiry procedure to allow better filtering of devices before connection; and sniff subrating, which reduces

10058-418: Was also the last update ever received as Asus abandoned it shortly thereafter. The optional docking keyboard features full QWERTY keys, touchpad as well as an additional battery that increases overall battery life from 8.5 hours to up to 15 hours. There are multiple reports of the screen cracking due to the amount of stress the hinges puts on the screen when opening and closing the unit. Weight: 640g without

10165-577: Was announced in September 2010 that ran the BlackBerry Tablet OS . The BlackBerry PlayBook was officially released to US and Canadian consumers on April 19, 2011. Hewlett-Packard announced that the TouchPad , running WebOS 3.0 on a 1.2 GHz Qualcomm Snapdragon CPU, would be released in June 2011. On August 18, 2011, HP announced the discontinuation of the TouchPad, due to sluggish sales. In 2013,

10272-476: Was highly hyped by the media during the early 1990s. Microsoft , the dominant PC software vendor, released Windows for Pen Computing in 1992 to compete against PenPoint OS. The company launched the WinPad project, working together with OEMs such as Compaq , to create a small device with a Windows -like operating system and handwriting recognition. However, the project was abandoned two years later; instead Windows CE

10379-589: Was initiated in 1989 by Nils Rydbeck, CTO at Ericsson Mobile in Lund , Sweden. The purpose was to develop wireless headsets, according to two inventions by Johan Ullman , SE 8902098-6 , issued 1989-06-12   and SE 9202239 , issued 1992-07-24   . Nils Rydbeck tasked Tord Wingren with specifying and Dutchman Jaap Haartsen and Sven Mattisson with developing. Both were working for Ericsson in Lund. Principal design and development began in 1994 and by 1997

10486-496: Was intended to be a table-top device named the Vosi Symphony, networked with Bluetooth. Through the negotiations with Motorola , Vosi introduced and disclosed its intent to integrate Bluetooth in its devices. In the early 2000s a legal battle ensued between Vosi and Motorola, which indefinitely suspended release of the devices. Later, Motorola implemented it in their devices which initiated the significant propagation of Bluetooth in

10593-468: Was originally limited to E-reading capabilities; however, an update to their Kindle firmware added the ability to browse the Internet and play audio, allowing Kindles to be alternatives to a traditional tablet, in some cases, with a more readable e-ink panel and greater battery life, and providing the user with access to wider multimedia capabilities compared to the older model. Two major architectures dominate

10700-456: Was ported to OpenBSD as well, however OpenBSD later removed it as unmaintained. DragonFly BSD has had NetBSD's Bluetooth implementation since 1.11 (2008). A netgraph -based implementation from FreeBSD has also been available in the tree, possibly disabled until 2014-11-15, and may require more work. The specifications were formalized by the Bluetooth Special Interest Group (SIG) and formally announced on 20 May 1998. In 2014 it had

10807-558: Was provided by DECT DMAP, only available in Europe and provided up to 10 Mbit/s. The device had 16 MB storage, 32 MB of RAM and x86 compatible 166 MHz "Geode"-Microcontroller by National Semiconductor . The screen was 10.4" or 12.1" and was touch sensitive. It had slots for SIM cards to enable support of television set-up box. FreePad were sold in Norway and the Middle East; but

10914-526: Was released in the form of " Handheld PCs " in 1996. That year, Palm, Inc. released the first of the Palm OS based PalmPilot touch and stylus based PDA, the touch based devices initially incorporating a Motorola Dragonball (68000) CPU. Also in 1996 Fujitsu released the Stylistic 1000 tablet format PC, running Microsoft Windows 95 , on a 100 MHz AMD486 DX4 CPU, with 8 MB RAM offering stylus input, with

11021-500: Was reworked to include more tablet features. Android 3.0 (Honeycomb) , released in 2011 and later versions support larger screen sizes, mainly tablets, and have access to the Google Play service. Android includes operating system, middleware and key applications. Other vendors sell customized Android tablets, such as Kindle Fire and Nook , which are used to consume mobile content and provide their own app store, rather than using

11128-493: Was that power consumption on cellphone technology at that time was too high to allow viable integration into a notebook and still achieve adequate battery life. Instead, the two companies agreed to integrate Ericsson's short-link technology on both a ThinkPad notebook and an Ericsson phone to accomplish the goal. Since neither IBM ThinkPad notebooks nor Ericsson phones were the market share leaders in their respective markets at that time, Adalio Sanchez and Nils Rydbeck agreed to make

11235-554: Was the Archos 5, a pocket-sized model with a 5-inch touchscreen , that was first released with a proprietary operating system and later (in 2009) released with Android 1.4. The Camangi WebStation was released in Q2 2009. The first LTE Android tablet appeared late 2009 and was made by ICD for Verizon . This unit was called the Ultra, but a version called Vega was released around the same time. Ultra had

11342-724: Was the only modulation scheme available. Since the introduction of Bluetooth 2.0+EDR, π/4- DQPSK (differential quadrature phase-shift keying) and 8-DPSK modulation may also be used between compatible devices. Devices functioning with GFSK are said to be operating in basic rate (BR) mode, where an instantaneous bit rate of 1   Mbit/s is possible. The term Enhanced Data Rate ( EDR ) is used to describe π/4-DPSK (EDR2) and 8-DPSK (EDR3) schemes, transferring 2 and 3   Mbit/s respectively. In 2019, Apple published an extension called HDR which supports data rates of 4 (HDR4) and 8 (HDR8) Mbit/s using π/4- DQPSK modulation on 4 MHz channels with forward error correction (FEC). Bluetooth

11449-534: Was then adopted by the UBports as a community project. As of February 2014, 83% of mobile app developers were targeting tablets, but 93% of developers were targeting smartphones. By 2014, around 23% of B2B companies were said to have deployed tablets for sales-related activities, according to a survey report by Corporate Visions. The iPad held majority use in North America, Western Europe, Japan, Australia, and most of
