Explain the modulation techniques used in Bluetooth technology.
Blue tooth uses Frequency Hopping Spread Spectrum technique which is used in
spread spectrum signal transmission. During radio transmission, frequencies are
switched repeatedly, to help reducing unlawful access to cross paths which
causes interruptions. FHSS makes Bluetooth communication more robust and
secure. The speed of interferences from other devices will be reduced, though
it will not cause the transmission to stop.
Adaptive modulation and coding methods, OFDM, GMSK, QAM, CDMA, DMT and similar
methods are utilized in the areas of wireless, cellular and satellite
communication systems. These modulations are used in wireless, cellular, wired
line and satellite communication systems.
New technologies such as MIMO, BLAST and space-time coding are used in
transmission data communication systems.
Bluebugging attacking is targeted for privacy issues that are specific to cell
phones and Bluetooth headsets. In order to succeed..............
The following are the differences between Bluetooth and
