The Evolution of Mobile Wireless
Generations
The recent development of wireless technology has made communication more familiar and accessible to all people. Wireless communication systems transmit waves from a fixed source to cover an area that spreads across a spectrum of waves. These are signals that are divided in the way they work into two types: Analog Signals and Digital Signals.
Analog signals are continuous signals that contain time-varying quantities (such as voltage, pressure, etc.). Analog signals can be used to measure changes in some physical phenomena such as sound, light, humidity, pressure, or temperature.
Digital signals represent data as a series of binary digits. In other words, digital signals represent information in discrete bands of analog levels.
Digital signals are used in all digital electronics, notably data transmission and computing equipment.
Analog signals depend on the properties of the waves in the sound transmission, which can be affected by any other factor. While digital signals depend on the use of waves to transmit data and these signals are generally not affected.
Examples of analog signals are human voice, analog phones, thermometer, etc.
Examples of digital signals are digital phones, digital pens, computers, etc.
Simply, the difference between analog signals and digital signals can be explained by looking at the following points:
Analog signals are difficult to analyze at first, while digital signals are easy to analyze.
Analog signals take time to be stored and have infinite memory while digital signals can be easily stored.
Analog signals produce a lot of noise while digital signals do not produce noise.
Analog signals have a continuous representation of signals while digital signals have a discontinuous representation of signals.
In our current world, Analog Signals are not used in any type of communication over telephone networks. This time, the total dependence is limited to digital signals transmitted in wave frequency from 300 MHz to 100 GHz.
So far, we have explained how the communication network works in general, let us talk about the generations of mobile wireless technology that we have seen during the last 40 years.
The current demand for mobile communication requires the integration of wireless technologies into existing networks such as wide area networks (WANs), local area networks (LANs), etc.
