Frequency spread refers to the distribution or range of frequencies present in a signal or sound. It describes the spacing and coverage of individual frequencies within a given range. A wider frequency spread means there is a greater variety of frequencies present, while a narrow spread indicates a more limited range of frequencies.
Frequency interleaving is a technique where consecutive symbols in a data stream are spread across different frequency subcarriers in a communication system. This helps combat frequency-selective fading in wireless channels by reducing the impact of frequency-specific signal impairments. By spreading the symbols across multiple frequencies, frequency interleaving helps improve robustness and reliability of the communication link.
Spread spectrum radio is a communication technique that spreads the signal over a wide frequency band. It enhances signal security, reduces interference, and improves signal quality by using a larger portion of the frequency spectrum. This technology is commonly used in wireless communication systems like Bluetooth and Wi-Fi.
The keyword "frequency" refers to how often a particular value appears in a dataset. The variation in data points within a dataset is related to how spread out or diverse the values are. Higher frequency of certain values can indicate less variation, while lower frequency can indicate more variation in the dataset.
High-frequency electromagnetic waves have shorter wavelengths and higher energy, appearing as shorter, more tightly packed waves. Low-frequency electromagnetic waves have longer wavelengths and lower energy, appearing as longer, more spread out waves.

FHSS(Frequency Hopping Spread Spectrum)
A frequency distribution plot.
velocity of light, amplitude , frequency etc
a. Direct sequence spread spectrum (DSSS). b. Frequency hopping spread spectrum (FHSS). c. Infrared d. Orthogonal frequency division multiplexing(OFDM)
The spread is the minimum value (not count) to the maximum value. The range is the maximum value minus the minimum value. Spread does not consider the frequency of the values, only the minimum and maximum.
A frequency diagram or, for grouped data, an histogram.
Modulation Index is the ratio of the maximum deviation frequency to the frequency of modulation. In other words it is the ratio of the spread in frequency spectrum to the frequency that was used to modulate the carrier. For FM, modulation index is given by the formula mf= df/f where, mf=modulation index for FM df=difference in carrier frequency f=frequency of the signal
Bluetooth technology operates in the unlicensed industrial, scientific and medical (ISM) band at 2.4 to 2.485 GHz, using a spread spectrum, frequency hopping.
