What's cellular about the cell phone is the network. Here's the diagram V. The genius of the cellular network is that it allowed much more efficient use of scarce radio spectrum. Carriers can use the same set of frequencies over and over without creating all kinds of interference. Repeat the pattern over and over and you can use both lower-power towers and much less spectrum to service the same number of customers.
As you walk or drive around the map, the mobile switching center hands you from one tower's infrastructure to the next one's. Or at least that's what happens when your call doesn't get dropped. And, yes, this is an idealized diagram, of course. But looking at it, you can see why it might be natural to call these little electromagnetic chambers punctuated with a base tower nucleus a cell. A Cell Phone is, therefore, a mobile phone that works utilising radio cells, which is an area of radio coverage.
Cell phones can typically be used while moving from one cell to another without losing coverage or dropping the connection. Satellite phones are not cell phones, although they are mobile phones. As mobile phones started evolving, they began to include additional basic features such as games, calendars, and connected email capabilities. These early mobile phones were referred to as feature phones, and they are still widely used in the lower ends of the market, or more recently, as a second phone to accompany your smartphone.
Its enhanced features and increased capabilities differentiated it from other mobile phones. Both Android and iPhones are clear examples of smartphones. Essentially, whether a cell or a mobile phone, you are referring to the very same mobile phone device.
How did it all start? Original mobile phones used a primary 1G system which initially made its first appearance in the USA in The company responsible was Motorola, and the brand new cellular network was initially termed 1G.
Cells are normally thought of as hexagons on a big hexagonal grid. Each cell has a base station that consists of a tower and a small building containing the radio equipment. Cell phones have low-power transmitters in them and the base station is also transmitting at low power. Low-power transmitters have two advantages:. The cellular approach requires a large number of base stations in a city of any size.
A typical large city can have hundreds of towers. But because so many people are using cell phones, costs remain fairly low per user. This office handles all of the phone connections to the normal land-based phone system, and controls all of the base stations in the region. The two base stations coordinate themselves through the MTSO, and at some point, your phone gets a signal on a control channel telling it to change frequencies.
