Frequency and Frequency Band in Mobile Cell Phone
Frequency and Frequency Band – The wave produced per second from a medium is called frequency. Specific range of frequencies is called frequency band.
Frequency and Frequency Band – The wave produced per second from a medium is called frequency. Specific range of frequencies is called frequency band. Let us understand in detail.
Frequency & Frequency Band
What is Frequency?
The wave produced per second from any medium is called frequency and is denoted by “F”. Unit of measuring frequency is “Cycles per Second”. It is denoted by C/S. “Cycle per Second” is also known as “Hertz” Unit. Hertz is denoted by Hz. C/S and Hz are same units. The units bigger than Hertz are correlated as follows:
- 1000 Hz (Hertz) = 1 KHz (Kilo Hertz)
- 1000 KHz = 1 MHz (Mega Hertz)
- 1000 MHz = 1 GHz (Giga Hertz)
Frequency Bands in Mobile Phones
A specific range of frequencies which are used in telecommunication for a particular purpose is called band. This is a part of long series of frequencies.
Band Width or Bandwidth
Bandwidth is a term used to define the quantum of frequency space taken by a signal and is necessary for effective transfer of the information carried by the signal.
Dual Band Devices
These are gadgets which have the capability of functioning under two different frequency bands. Generally mobile cell phones work on dual band frequency network. It is designed to work on 900 MHz and 1800 MHz. It is called 900 MHz or GSM900 Band. Its bandwidth is between 935 to 960 MHz. 1800 MHz band is called GSM1800 or DCS1800. Its bandwidth ranges from 1805 to 1880 MHz.
Frequency and Frequency Band in Mobile Cell Phone FAQs
Why is frequency important in mobile cell phones?
Frequency is important in mobile cell phones because it determines the range and capacity of the wireless network. Different frequency bands have different strengths and limitations, and it's important for cell phone manufacturers and carriers to use the appropriate frequency bands to ensure reliable communication.
What are the most common frequency bands used in mobile phones?
The most common frequency bands used in mobile phones are 850 MHz, 900 MHz, 1800 MHz, 1900 MHz, 2100 MHz, and 2600 MHz. These bands are used for different types of communication, such as voice calls, text messages, and data transmission.
What is a frequency band in mobile phones?
A frequency band in mobile cell phones refers to a range of frequencies within the radio spectrum that is used for wireless communication. Different frequency bands have different characteristics and are used for different purposes.
How does the frequency band affect my cell phone’s performance?
The frequency band that your cell phone uses can affect its performance in several ways. For example, a higher frequency band may offer faster data speeds but have shorter range, while a lower frequency band may offer longer range but slower data speeds. Additionally, different frequency bands may be used in different regions or countries, so your cell phone may not work in certain areas if it doesn't support the appropriate frequency bands.

thanks for the iinnfos sir do you have a youtube channel?
Hay r u sure 100KHz=1MHz.. Just checking…
Sorry for the typing mistake. 1000 KHz = 1 MHz.
Are you sure the information in the ‘Dual Band Devices’ paragraph is correct or are there a couple of typos? Just checking.
Thanks for pointing out my typing mistakes. I have now corrected it. I appreciate your valuable input. Thanks!
