Note that obtaining the information is out of scope in this paper, but there are several approaches to get the information, e.g., [7,8]. Unfortunately, with the introduction of AFH in the Bluetooth Core Specification Version 1.2 published in 2003, obtaining the actual hopping sequence is more complex.

Frequency hopping/time hopping (FH/TH) sequences have found wide applications in various modern FH/TH spread spectrum communications, such as … philippine scout ranger logo pngFrequency-hopping spread spectrum (FHSS) is a method of transmitting radio signals by rapidly changing the carrier frequency among many frequencies occupying a large spectral band. The changes are controlled by a code known to both transmitter and receiver. FHSS is used to avoid … Meer weergeven Military Spread-spectrum signals are highly resistant to deliberate jamming unless the adversary has knowledge of the frequency-hopping pattern. Military radios generate the … Meer weergeven The overall bandwidth required for frequency hopping is much wider than that required to transmit the same information using only one carrier frequency.
