Why frequency hopping is used?
TSK
What is frequency hopping in gsm?
Multi wave propagation varies the signal strength which causes fading dips. This is known as Rayleigh fading which is frequency dependent. Frequency Hopping changes the frequency with time to eliminate frequency dependent Rayleigh fading. Frequency Hopping reduces the effects of interferences and gives a great support to cater the capacity upgrading as well.

What is fast and slow frequency hopping?
Fast frequency hopping refers to a technique in wireless communication where the carrier frequency changes rapidly, often several times per second, to minimize interference and enhance security. Slow frequency hopping, on the other hand, involves changing the frequency less frequently, typically only a few times per minute, which can be simpler to implement but may be more susceptible to interference. Both methods are used in spread spectrum communication systems to improve resistance to jamming and eavesdropping. The choice between fast and slow hopping depends on the application requirements, such as bandwidth efficiency and robustness.
What famous entertainer was presented an Electronic Frontier Foundation for invention of frequency hopping?
Hedy Lamarr
What do you mean by Antenna Hopping in GSM?
Antenna hopping is a feature in which the Tx/Rx is passed through all the available antenna paths in a sector. No frequency is changed during antenna hopping. This helps improve performance by providing spatial diversity.
Difference between Frequency hopping spread spectrum and direct sequence spread spectrum?

What is the maximum frequency one can allocate to a TRX during RF hopping?
The maximum frequency one can allocate to a Transceiver (TRX) during RF hopping depends on the specific communication standards and regulations in place, such as those set by the FCC or other relevant authorities. Generally, frequency hopping spread spectrum (FHSS) systems must adhere to certain bandwidth and frequency separation requirements to avoid interference and meet legal specifications. In practice, the maximum frequency allocation can vary widely based on the system design and intended application, but it is typically constrained by the overall bandwidth available within a given frequency band.
Frequency and cumulative frequency are two types of what?
Frequency and cumulative frequency are two types of frequency distributions. These are frequency tables that show statistical data for different types of frequencies that include absolute, relative, and cumulative frequencies. There are mathematical formulas used to calculate these frequencies.
What is the frequency blue tooth runs on?
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.
