Martin Cooper invented the cellular phone. He conceived this idea when the need for people to communicate had become more pressing. He got the concept of a mobile phone from watching Star Trek showing how the crew managed to talk to each other with their communicators.
The invention of cellphone allowed room for the technology and communications market to focus on the individual and not where the individual is. This was borne of the idea that people wanted to talk to people regardless of being in the house, in a car, or even far away from both places.
History of the Cellphone
The cellphone started as something that was slightly larger than the standard telephone. Back then, cordless phones were not even available. This kind of technology was something new as it gave people the freedom to make phone calls while moving around and being able to multitask.
The personal communications device proved to be of great use. This is especially true for the business sector. However, it took a long time for mobile phones to be available to everyone. This was because the service providers were swamped and could not perform their service properly. The demand outstripped the capacity of the providers to improve their services and technology, causing the overcrowding of the airspace.
Today, the only way for the technology to be readily available is for existing cells to be split and managed separately. The technology has to have the capacity to deal with more customers, and therefore more cells.
The Wireless Standards
The drive to improve wireless communication gave birth to two standards of communication: analog and digital.
Analog services work by radio signal communication so that standard radio frequencies could carry voice and data. Analog mobile phones work similarly to FM radios. The transmitter and the receiver tune in to equal frequency range. This works by transmitting the voice, reconstructing it with the receiver, amplifying it, and then sending it to the other side. However, this kind of service is limited because there are very limited useful channels.
The digital service works by encoding the data in binary code. The raw voice signal converts into a binary code first and then it is transmitted accordingly. The disadvantage of such technology is that the three types of wireless technologies (TDMA, CDMA, and GSM) may not be compatible with one another.
Eventually, the digital method surpassed the analog method and is the more widely used standard today.
