Bluetooth simulation Bluetooth frequency hopping simulation

Bluetooth Standard — Frequency Spectrum Bluetooth uses gaussian frequency shift keying (GFSK) to modulate the data to frequencies around 2.4 GHz. The frequency spectrum is divided up into 79 channels spaced 1 MHz apart. Data is transmitted at 1 Mbps. For security benefits and noise reduction, a Bluetooth transmitter employs frequency hopping, switching channels up to 1600 times a second

Bluetooth technology Bluetooth is a low cost, low power, radio frequency technology for short-range communications. It can be used to replace the cables connecting portable/fixed electronic devices, build ad-hoc networks or provide data/voice access points

Bluetooth vs. WiFi: — why it’s NOT a death match [ZDNet] Bluetooth operates at about 720kbps, WiFi at 11mbps. (802.11b = WIFI)

Bluetooth vs. WiFi Bluetooth devices operate within the 2.4 GHz band. The difference is that that Bluetooth uses frequency hopping (at 1,600 hops per second) to hop over the entire 2.4 GHz band. 802.11b, on the other hand, uses direct sequence and only occupies approximately one third of the 2.4 GHz band, …, ISM Band: 2.402 GHz —> 2.480 GHz, every band is 1 MHz
