A smartphone is a mobile phone and a personal computer. Unlike traditional phones and “basic” cell phones, smartphones offer extensive computing capabilities, including many third-party software applications (mobile applications) acquired through an application store and high-speed Internet access (mobile broadband). ). In addition to the capacity of high-speed Internet service (usually long-term (LTE)), most, if not all, smart phones also support Wi-Fi, Bluetooth, and satellite navigation; and usually come with two to three digital cameras. The sensors usually included on a smartphone include an accelerometer, a gyroscope and a magnetometer, and provide one to two LEDs for lighting and photographic flash needs. Smartphones have touch screens, and the interaction with smartphones is mainly through touch, in addition to some physical buttons. Smartphones are usually handheld, with slightly larger sizes called phablettes, and they are usually smaller than tablets. Smartphones are generally operated by a major mobile operating system and not by custom-designed software typically used to operate phones and cell phones. Just like basic and feature phones, smartphones are used with a cellular network connection for the voice.
Like feature phones and some basic phones, smartphones support Short Message Service (SMS). Like some feature phones, smartphones provide support for data communication over the Internet and share high-speed Internet (LTE) capabilities with some special feature phones. Smartphones work with a rechargeable battery. Smartphones are capable of running a variety of software components, called “apps”. Most basic applications (event calendar, camera, web browser, etc.) are pre-installed with the system, while others can be downloaded from official sources such as the Google Play Store or Apple App Store. Applications can receive bug fixes and gain additional functionality through software updates; Likewise, operating systems are able to update themselves. Mobile payment is now a feature of most smartphones. Modern smartphones feature a color touch screen with a graphical user interface that covers the front surface and allows the user to use a virtual keyboard to tap and tap the on-screen icons to activate the applications. Today, smartphones largely meet the needs of their users in phone, digital camera and video camera, GPS navigation, media player, clock, news, calculator, web browser, portable video player, flashlight, compass, notebook addresses, etc. take, digital messaging, a calendar of events, etc. Typical smartphones will include one or more of the following sensors: magnetometer, proximity sensor, barometer, gyroscope or accelerometer. Since 2010, smartphones have adopted integrated virtual assistants, such as Apple Siri, Amazon Alexa, Google Assistant, Microsoft Cortana, BlackBerry Assistant and Samsung Bixby. Most smartphones manufactured from 2012 have a high-speed 4G LTE mobile broadband connection. In 1999, the Japanese company NTT DoCoMo released the first smartphones for massive adoption in a country. Smartphone sales began to grow rapidly in the late 2000s. In the third quarter of 2012, one billion smartphones were used worldwide. Global smartphone sales surpassed mobile phone sales in early 2013.
The first commercially available device that could be called a “smartphone” began as a prototype called “Angler” developed by Frank Canova in 1992 at IBM and presented in November of the same year at COMDEX. A refined version was marketed to consumers in 1994 by BellSouth as Simon Personal Communicator. In addition to making and receiving cellular calls, Simon, equipped with a touch screen, can send and receive faxes and e-mails. It included an address book, a calendar, an appointment planner, a calculator, a world clock and a notepad, as well as other visionary mobile apps such as maps, stock reports and news. The term “smart phone” or “smartphone” was invented only one year after the introduction of Simon, appearing in print in 1995, describing AT & T’s PhoneWriter Communicator.
The first integration of data signals with telephony was conceptualized by Nikola Tesla in 1909 and initiated by Theodore Paraskevakos from 1968 with his work on the transmission of electronic data over telephone lines. In 1971, while working with Boeing in Huntsville, Alabama, Paraskevakos demonstrated a transmitter and receiver that offered additional ways to communicate with remote equipment. This formed the original basis for what is now known as Caller ID. The first caller identification equipment was installed at Peoples’ Telephone Company in Leesburg, Alabama, and was introduced to several telephone companies. Original and historical work patterns are still in Paraskevakos’ possession.
