welcome everybody today my partner and I are going to talk about the phones.
The mobile phone is an electronic wireless device that allows access to the cellularnetwork or mobile. Cell is called in most Latin American countries because the service operates through a network of cells, where each antenna signal repeater is a cell,although there are satellite mobile telephone networks. Its main feature is its portability, which allows you to communicate from almost anywhere. The primary function is voicecommunication, such as the telephone.
From the twenty-first century mobile phones have acquired features that go far beyond simply just call or send text messages, you couldsay that these were combined (not replaced) with various devices such as PDA, camera , alarm clock, calculator, micro-projector, GPS or multimedia player and able to performactions in a multitude of small, portable device that has almost everyone in developed countries. This type of evolution of the mobile phone is called smartphone.
The firstrecord is about the mobile phone company Motorola DynaTAC 8000X with its model. The model was designed by engineer Rudy Krolopp Motorola in 1983. The model weighed just undera kilo and was worth nearly U.S. $ 4000. Krolopp be incorporated later to research and development team led by Motorola Martin Cooper. Both Cooper and Krolopp appear asowners of the original patent. From the DynaTAC 8000X, Motorola would develop new models like the Motorola MicroTAC, launched in 1989 and the Motorola StarTAC, launched in 1996to market.
Currently have major mobile touch phones, which follow the trail of the iPhone.
