Smart Phone 1

     ELECTRONICS INFORMATION

       Here I am sharing the all type of information about electronics.New information about new technology.Here in this blog our topic is smartphones ,there generations there features and so on.

SMARTPHONE;

A smartphone is a mobile phone that can do more than other phones. They work as a computer but are mobile devices small enough to fit in a user's hand. The world's first Android smartphone – 10 years on. Long before the likes of the the Samsung Galaxy range Google took the smartphone scene to a new level with the arrival of Android on the T-Mobile G1. Ten years ago the HTC made, slider keyboard device was the first to use the operating.

Features;

 Smartphones are a class of mobile phones and of multi-purpose mobile computing devices. They are distinguished from feature phones by their stronger hardware capabilities and extensive mobile operating systems, which facilitate wider software, internet (including web browsing[1] over mobile broadband), and multimedia functionality (including music, video, cameras, and gaming), alongside core phone functions such as voice calls and text messaging. Smartphones typically include various sensors that can be leveraged by their software, such as a magnetometer, proximity sensors, barometer, gyroscope and accelerometer, and support wireless communications protocols such as Bluetooth, Wi-Fi, and satellite navigation.

GENERATION OF SMART PHONES;

1.The first commercially available device that could be properly referred to as a "smartphone" began as a prototype called "Angler" developed by Frank Canova in 1992 while at IBM and demonstrated in November of that year at the COMDEX. since 1G systems were introduced in 1981/1982. Each generation is characterized by new frequency bands, higher data rates

2. 2G (or 2-G) provides three primary benefits over their predecessors:phone conversations are digitally encrypted; 2G systems are significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels; and 2G introduced data services for mobile, starting with SMS (Short Message Service) plain text-based messages. 2G technologies enable the various mobile phone networks to provide the services such as text messages, picture messages and MMS (Multimedia Message Service). It has 3 main services: Bearer services is one of them which is also known as data services and communication.Second generation 2G cellular telecom networks were commercially launched on the GSM standard in Finland by Radiolinja (now part of Elisa Oyj) in 1991.

3. 3G technology provides an information transfer rate of at least 200 kbit/s. Later 3G releases, often denoted 3.5G and 3.75G, also provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. This ensures it can be applied to wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV technologies.

4. 3.5G is a grouping of disparate mobile telephony and data technologies designed to provide better performance than 3G systems, as an interim step towards the deployment of full 4G capability. The technology includes: 1.High-Speed Downlink Packet Access 2.3GPP Long Term Evolution, precursor of LTE Advanced.

5. 4.5G provides better performance than 4G systems, as an process step towards deployment of full 5G capability.[2] The technology includes:

LTE Advanced Pro

MIMO

6. 5G is a generation currently under development. It denotes the next major phase of mobile telecommunications standards beyond the current 4G/IMT-Advanced standards.NGMN Alliance or Next Generation Mobile Networks Alliance define 5G network requirements as:

Data rates of several tens of Mb/s should be supported for tens of thousands of users.

1 Gbit/s to be offered, simultaneously to tens of workers on the same office floor.Several hundreds of thousands of simultaneous connections to be supported for massive sensor deployments.

Spectral efficiency should be significantly enhanced compared to 4G.

Coverage should be improved.

Signalling efficiency enhanced.

Latency should be significantly reduced compared to LTE.[3]

Next Generation Mobile Networks Alliance feel that 5G should be rolled out by 2020 to meet business and consumer demands.[4] In addition to simply providing faster speeds, they predict that 5G networks will also need to meet the needs of new use-cases such as the Internet of Things as well as broadcast-like services and lifeline communications in times of disaster.
