Taking a Look at a Cellular Network

Cellular communications is such a large aspect of today’s industries, and with the number of consumers already with cell phones drastically increasing all the time, it is good to think about the future, and maybe making the customers you already have, happy and content. There are only so many “new” customers you can gain in today’s market. Phone

The first cell phone was created by Martin Cooper on April 3rd, 1973. Cell phones are radio receivers and transmitters that use electromagnetic energy to send and receive information. Energy travels in waves. The distance from one wave to the next is the wavelength. Frequency is the amount of times the wave oscillates up and down per second. The higher the frequency, the more energy. Frequency is measured in Hertz. One Hz is one wavelength per second. Different electronical things are operated at different rates of hertz. At this point, the fastest connection runs at a 2.1 GHz (gigahertz) range-- that’s 2.1 billion wavelengths per second. Cell phones use low radiation called radio frequency (RF). A cell phone sends and receives

When telephones were first introduced, customers were bound by switchboards. They could only contact those in certain areas. Slowly, as technology broadened and switchboards were no longer needed, customers could contact within other companies, other areas and eventually even globally. In the beginning,

A mobile phone (also known as a cellular phone, cell phone, and a hand phone) is a device that can make and receive telephone calls over a radio link while moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network. By contrast, a cordless telephone is used only within the short range of a single, private base station.

Small cells mainly consist of the femtocells, picocells, and microcells. The network can also be known by “distributed radio technology” which consists of centralized baseband units and remote radio heads. “Beamformingtechnology (focusing a radio signal on a very specific area) can be utilized to further enhance or focus small cell coverage”. The common factor binding all of these technologies is that all are centrally managed. [13]

A cell phone is an electronic device used for the mobile telecommunication i.e. mobile telephony, data transmission and text messaging. It is used over a cellular network of specialized base stations. It differs from cordless telephones, which offers telephony service only within a limited range i.e. within a home or an office. As the time passes it offers more and more advance features. A society is a social, economical or industrial infrastructure,

sometimes abbreviated as “cp” is a mobile phone or portable phone that enables a user to

The technology today is much less simple than the technology previously created. Telecommunication was first brought to existence in 1947, but more important is the first mobile telephone introduced in Sweden in the 1960’s. Sweden focused on the reliance of a car through technology. So in other words, the system had been animated with the connection from a handset, which remained to be operated to forward incoming calls. As the first generation of cell phones approached, cell towers had been built all around. That is how calls had been made. Cell phones that were in use had to be connected to a cell tower. They called this the “Analog Cellular Networks” (Brookes). Cell phones were just strictly used for calling. Pagers had been created that just let off

- EMERGENCY CALLS: If any person makes an emergency call using a regular phone, the call gets diverted towards the nearest call center based on your location. However as VoIP is basically a transfer of data between two IP addresses, and not physical addresses hence there is no way to determine the origin of the call.

A mobile phone works on a unique networked system which needs no wiring, no fixation and no botheration. Originally it was used in cars, airlines, and passenger trains but increasingly it is becoming ubiquitous. It is basically low- power radio telephone. In this magical system calls go through radio transmitters that are located within small geographical unit which are known as cells. Since each cell's signals are too weak to interfere with those of other cells operating on the same frequencies and more channels can be used than would be possible with high power radio frequency transmission. Narrow-band frequency modulation (FM) is the most common mode of transmission, each message is assigned a carrier, unique to the cell from which it is transmitted.

Telecommunications is something that every single one of us is using in one form or another throughout our daily lives, whether it’s
