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 the signaling method used by Bluetooth?
FHSS(Frequency Hopping Spread Spectrum)
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?
Spelling difference.... :)
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.
Frequency and cumulative frequency are two types of?

Are gsm use sfh to improve signal?
Frequency Hopping is an old technique introduced firstly in military transmission system to ensure the secrecy of communications and combat jamming. Frequency Hopping is mechanism in which the system changes the frequency (uplink and downlink) during transmission at regular intervals. It allows the RF channel used for signaling channel (SDCCH) timeslot or traffic channel (TCH) timeslots, to change frequency every TDMA frame (4.615 ms). The frequency is changed on a per burst basis, which means that all the bits in a burst are transmitted in the same frequency.
What types of radiation has the highest frequency?
In the electromagnetic spectrum Gamma radiation has the highest frequency.
