T-Mobile protest Verizon’s plan to buy spectrum.

Hi,

Spectrum, or frequency spectrum is the amount of frequency band allocated to a TV, Radio, or Telecom operators, it is controlled by the government regulator, this last will be in charge of distributing the spectrum among all the users (TV, Radio, Sat, Military…).

The rules of physics stats that if you are sending information over a frequency band, the amount of data that you can send in a fixed amount of time will be depending on the amount of frequency band that you are using, in other words, the number of kbps that you can send depend on the frequency band you are using in addition to some other parameters such as the coding.

To make it simpler:

 The GSM 2G uses 0.2 MHz frequency carrier–>low bandwidth and data rate

The UMTS 3G use 5 MHz frequency carrier–>Medium bandwidth and data rate

The LTE 4G use 20 MHz frequency carrier–>High bandwidth and data rate

Thank you

In wireless, the term spectrum refers to the radio portion of the electromagnetic spectrum. The radio spectrum is a joint grouping of different radio waves that are used by devices to communicate with each other. A variety of communications devices like mobile phones, Wi-Fi, as well as the remote control for the garage door uses radio waves. The radio spectrum spans a specific limited frequency range.

Numerous signals can be transmitted concurrently on different frequencies. But if the frequencies of the transmitted signals are the same or maybe very close, the signals interfere with each other. Also, radio signals spread out and die away over geographic distance. For example, if there are two radio transmitters located on the same city and using the same frequency, they would probably obstruct one another.

But if the other radio transmitter is located on a different city, the possibility of interfering one another is unlikely to happen.
