A mobile phone, smartphone news, phone, cellphone often simplified to just a mobile phone, a cell phone, or just a phone, is a mobile phone that can make and receive calls over a radio frequency connection. At the same time, the user travels within a service area. The radio frequency link establishes a reference to a mobile phone operator’s switching system and provides access to the public switched telephone network (PSTN). Modern mobile phone services in North America use cellular network infrastructure, and thus mobile telephones are called mobile phones like Motorola Razr.
Smartphone news In addition to telephony, mobile phones or smartphones from the 2000s offers a variety of other features, including text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, video games, and digital photography. Mobile phones providing only those features are known as feature phones; smartphones are referred to as mobile phones offering considerably advanced computing capabilities.
The advancement of large-scale metal-oxide-semiconductor (MOS) integration (LSI) technology, information theory, and cellular networking led to the development of inexpensive mobile communications. John F. Mitchell and Martin Cooper of Motorola introduced the first portable mobile phone in 1973, using a c-weighing handset. Two kilograms (4.4 lbs) Nippon Telegraph and Telephone (NTT) launched Japan’s first cellular network worldwide in 1979.
Smartphones are a class of mobile phones and mobile computing devices for multi-functional use. They are identified from feature phones by their more robust hardware capabilities and extensive mobile operating systems that facilitate broader software, internet (including web browsing over mobile broadband), and multimedia (including music, video, cameras, and gaming) functionality alongside core phone functions such as voice calls and text messaging.
Smartphones usually contain metal–oxide–semiconductor (MOS) integrated circuit (IC) chips, including various sensors that can be leveraged by their software (such as a magnetometer, proximity sensor, barometer, gyroscope or accelerometer) and support wireless communication protocols (such as Bluetooth, Wi-Fi or satellite navigation).
Modern smartphones like Motorola Razr were mainly targeted towards the enterprise market, attempting to bridge the functionality of standalone personal digital assistant (PDA) devices with cellular telephony support but constrained by their bulky form, short battery life, sluggish analog mobile networks, and immaturity of wireless data services. These problems were eventually resolved with the exponential scaling and miniaturization of MOS transistors down to sub-micron rates (Moore’s law), the improved lithium-ion battery, faster digital mobile data networks (Edholm’s law), and more mature software platforms that enabled mobile device ecosystems to grow independently from data providers.
NTT DoCoMo’s I platform, BlackBerry, Nokia’s Symbian platform, and Windows Mobile began to gain market traction in the 2000s, with models often featuring QWERTY keyboards or resistivity touchscreen input and emphasizing push email and wireless internet access. Since the unveiling of the iPhone in 2007, most smartphones have featured thin, slate-like shape factors, with large, capacitive screens that support multi-touch gestures rather than physical keyboards, and offer users the ability to download or purchase additional apps from a centralized store, and to use cloud storage and synchronization, virtual assistants, as well as mob assistants
Improved hardware and faster wireless communication (due to standards like LTE) have boosted smartphone industry growth. One billion smartphones were in use worldwide in the third quarter of 2012. In early 2013, global smartphone sales outperformed the sales figures for the best future smartphones.
