The Communication Concepts Model: A Look into the Cellular Phone Voice Call By: Brianna Person

Encoding Defined: Recode or modify information into a desired format or pattern for a specific method of transmission or storage Sub Concept: Converting Acoustical to Electrical Energy: To change acoustical waveforms (noise) into an electrical signal.

Transmitting Defined: To convey information from one location to another Sub Concept: Duplexing: Process is which both ends of the communication can send and receive signals at the same time. –Full-Duplex: Both directions at the same time. Switching: Process that allows for the interconnection of more than two communication devices.

Cell phones operate on a duplex system, which uses two frequencies – one for talking or sending, and one for listening or receiving

Receiving Defined: The process of capturing a signal and then relaying it to the decoding device Sub Concept: Collecting: The capturing an electromagnetic wave that has been propagated by a transmitting antenna. Connecting: The physical channels that move the signal to the decoding process.

When you dial a particular number, the base station will automatically identify that number and assign an encrypted code on its transmission Cell phones also operate within cells and they can switch cells as they move around

Storing Defined: Processes are concerned with holding and retaining data for use at some later time Sub Concept: Memory: The processes that are used to acquire, store, retain and later retrieve information. –i.e. SIM Card

They are a quick and easy solution to prevent borders, carriers or locked-down phones from slowing you down. SIM cards keep all of the information that is needed right on your phone.

Retrieving Defined: Recalling information from a stored condition Sub Concept: Indexing: The process of coding an item for retrieval purposes.

Electronic Serial Number is issued to each phone for the life of that cell phone The ESN is used so that every time you call someone, a central system identifies you as the caller

Decoding Defined: Presenting information in such a way that the user can benefit from it Sub Concept: Converting Electrical to Acoustical Energy: To covert the electrical signal back into a form that people can understand

Don't think of a cell phone as a telephone, think of it as a radio Calls can be intercepted!
