In today's era, wireless technology is becoming more relevant each and every day. As technology evolves, wireless cellular technology evolves and it has been one of the biggest breakthroughs in wireless technology communication. That breakthrough being of course, the "Cell Phone." What are cell phones, and what specifically is the technology that goes into the cell phone giving the device all of its features and capabilities?
A "Cell Phone" is actually a radio because of how they are constructed to work. Cell phones are full-duplex devices, which enable cellphones to communicate with one another simultaneously in real-time. These devices are given the ability to own and utilize two different frequencies, that is, one to 'send' communication and the other to 'receive' communication via another technology device. What is most fascinating about these devices is that they are authorized to utilize BOTH frequencies at the same exact time.
The actual strength of these frequencies all directly are dependent on the location of the cellular device, as well as the user's carrier the phone is subscribed to (which is illustrated in the photo above). The cell phone is engineered to pick up on frequency connections according to what 'zone' the device is present in. Each city is divided into these different 'zones' simply for the allocation of available frequencies for a cell phone to use, which enables the millions of wireless cellular devices to operate at the same time with little noise in its path.
Many factors go into the cell phone configuration, such as:
Global System for Mobile Communication (GSM): originated in 1991 and was the original '2G' network. Encryption was used relatively uncommon during 1991, but their deployment of this new idea was successful (2G) and wireless communication has skyrocketed ever since. GSM is widely used in numerous countries, covering a vast majority of the world we live in today. Although, the United States is covered through something a little different.
Code Division Multiple Access (CDMA):almost the entirety of the United States is covered through CDMA, compared to other countries around the world, like Europe. How CDMA works is, it encodes multiple connections, while using various keys, and then the receiving end is decoded. One of the many reasons the use of CDMA is so prevalent is because the most dominant cell phone carrier uses CDMA; Verizon Wireless.
Long Term Evolution (LTE):LTE provides an increasingly upgraded amount of available bandwidth for any type of data and/or communication. It provides different types of radio interfaces to allow these different types of communication travel.
Voice over Long Term Evolution (VoLTE):VoLTE is a type of voice technology that only works with the LTE data connections, generating EXTREMELY high-quality communication. It can be excercised through voice communication, data communication, and video communication.
