| A transceiver device is a type of gadget that enables | | | | handling two frequencies simultaneously which enables |
| the user to transmit and receive signals on a given | | | | it to utilize one for talking and another one for |
| frequency range. In fact, you may have been using | | | | sending. This type of transmission is called a duplex |
| some of these transceiver devices. Two of the most | | | | system where both persons can talk, and hear each |
| common are radio transceivers, or more popularly | | | | other, all at the same time. The other difference lies |
| known as ham radios or walkie-talkies, and cellular | | | | in the fact that radio transceivers can communicate |
| phones, which is also a type of transceiver gadget. | | | | with each other directly without the use of any |
| Between these two, however, you might begin to | | | | intermediary devices, while cellular phones are |
| ask which one is better? In order to decide which of | | | | dependent on base stations which controls the data |
| these two devices is better, one has to understand | | | | that it receives or transmits. |
| first how these two types of transceivers work and | | | | Since cellular technology operates on a broad |
| their given capabilities. | | | | spectrum of radio frequencies, the base stations can |
| Cellular phones are also actually radios because they | | | | transfer the mobile phone to another cell site as soon |
| utilize radio frequencies in order to broadcast their | | | | as it detects that the phone that is transmitting the |
| signals. So where does the difference between the | | | | signal is getting out of range. This simply means that |
| two lie? In radio transceivers, a single frequency is | | | | for as long as there is a service signal from a cellular |
| shared by users on both ends. When a user presses | | | | base station, you are assured that you can use your |
| the Push-To-Talk or PTT button on his radio | | | | cellular phones anytime you want. This is a far cry |
| transceiver unit, everyone on that same frequency | | | | from radio transceivers which would only be service |
| will be able to hear him talk. | | | | capable only up to a certain range. |
| As you may have seen in some police action movies, | | | | There are a lot of differences between cellular |
| when the radio operator on the police station | | | | phones and radio transceivers. In the end, the |
| requests for units near an area, everybody on the | | | | decision on which is better lies on the end user. If it |
| same frequency hears the call and will respond | | | | will be within one area, like a construction site, radio |
| accordingly. This type of transmission, however, will | | | | transceivers would probably be the most practical |
| only allow one person to talk at any given time | | | | communications device to use. However, if there is a |
| because they only use a single frequency. This type | | | | possibility that you would be sending out emails with |
| of radio transmission is called a simplex system. | | | | photo attachments, then cellular phones would be the |
| Cellular phones, on the other hand, is capable of | | | | best choice. |
