Wireless technology has had a lot of development and growth in the recent years and one thing that has had great development has been mobile phone. Mobile phones are also known as cell phones or cellular phones or simple cells that are used by millions of people worldwide for long and short distance communication. Since its introduction in late 1970, it has greatly affected the activities we do on a daily basis. Many benefits of mobile phones include ease of interacting with each other. Mobile phones work as a clock. Mobile phone alarms wake us up in the morning.

All these technological advancements of cellular telephony have greatly benefited the humans.

Also due to this, today’s wireless technology has enabled applications which ease up the tasks like language translator applications on cell phones, ovulation cycle calculator on android phones but all these applications require greater bandwidth consumption.

How Do Cell Phones Work? (Science in the Real World)

How Cell Phones Work?

In the past, the idea of cellular technology was diving whole city into small cells. This idea allowed re-use of frequencies throughout the city which helped in allowing millions of people to interact on their cell phones at one point of time. In analog telephony, the cell phone network provider used to receive around eight hundred frequencies to be used throughout each city. Then, the network provider divided each city into small cells. Each cell usually consisted a size of approximately 26 km2. Cell phone network providers designed these cells as six sided figures or hexagons. Now, cellular network providers divided each cell with a base station which consisted of one tower and one small building containing some radio equipment. Now each cell in analog system used 1/7th of voice channels, i.e., a cell plus 6 cells surrounding the hexagonal arrangement and each used 1/7th of available channels, so each cell had a different set of frequencies and no collisions with each other. A cellular network provider got eight hundred and thirty two radio frequencies to use in one city.

Each mobile phone used 2 frequencies for one call, so there were 395 voice channels/carrier signal and the remaining forty two frequencies were used for control channels.

Now it is interesting to note that each cell consisted of about fifty six voice channels which in simple terms mean that fifty six cell phones users were interacting on their mobile phones at one point of time.

But with the introduction of digital transmission, the no. of available cell phone channels increased.

Cell phones are in low power transmitters. Many cell phones consist of two signal strengths: 3.0 watts and 0.6 watts. Cellular stations are also transmitting low signals. These low-power transmitters have two types of advantages and that are: First of all, transmission of base station and phones in same cell do not leave it. Therefore, it was possible for every cell to reuse same fifty six frequencies across the whole city. Secondly, power consumption of cell phone, usually battery operated, is relatively low. Low power means small batteries, which makes cell phones light and easy to use. So this was how cell phones work. In my next hub, I will write on history of cell phones and what is inside the cell phones.

Good hub. I like that you are explaining the networks. Being in the industry, I have decided to blog more about phones instead of the networks but that needs to be done as well. Good job.
