Evolution of Smartphones over time
#Cosmoread: A smartphone is a mobile phone with advanced features to help ease our day to day chores with the flexibility of doing everything on the go. It consists of a mobile operating system similar to that of a PC. It also has the facility to install and uninstall any programs, popularly known as “Apps” just like a PC. So, it is a communication device with the power to do more in your pockets. Different smartphones come with different features, based on which their price range from a mere Rs 500 to Rs 60000+. They typically combine the features of a cell phone with those of other devices, such as PDA, mp3 and video player, GPS, The Internet, Games, sensors for security like fingerprint sensor, etc. Most smartphones have a touchscreen user interface, with either an LCD, OLED, AMOLED, LED or similar screen. It can run third-party apps and have advanced camera hardware and software.
The idea of embedding intelligence into a communication device goes way back into the 1970s, but the mass adoption of the smartphones started in around 1999 when the Japanese firm NTT DoCoMo released the first smartphones to achieve mass adoption within a country. It ran on i-mode, had limited functionalities, small screens and a bandwidth of up to 9kbps. Who would have thought that the 9 Kbps would become up to 150 Mbps?
The smartphones run on the mobile operating system. As of today, they are Android, iOS, Blackberry and Symbian. Symbian developed by Nokia was the most popular one as OS to smartphones until 2010 when Android developed by Google, an open source OS, superseded the Symbian. This was because it was available to open source for which provided many mobile app developers a platform to play with their apps. This resulted in the evolution of the Google Playstore which helped Android to become the most loved OS.
With the evolution of smartphones, the technology it uses for communication has also evolved to a very advanced one. For example, as you can see the communication started from 1G then 2G, 2.5G, 3G and now the latest technology the world uses is the 4G. The data transfer with the voice has improved from mere 9.6 Kbps to around a possible speed of around 21 Mbps (wireless). Also, the technology for voice as of today are GSM, CDMA, WCDMA and LTE with the latest in line i.e. VoLTE. These technologies over a minuscule portable device, i.e. a smartphone have provided every individual the flexibility to do multitasking at ease. In times as of now the PCs have just become the necessity of professionals. Most of the work or fun can be done through a smartphone today.
After nearly two decades of the first mass adoption of smartphones, today, it is very rare to find an individual without a smartphone. The ease of communication, reduction of cost for the same, accessibility of the internet, etc. has made it a necessity even for a common man.
