The protocol used by wifi is the ieee802.11b LAN protocol, which uses DSSS (Direct Sequence Spread Spectrum) and QPSK or BPSK (Phase Shift Keyer), the transmission distance is 100 meters, and the maximum speed can reach 11Mbps. The bandwidth is 22MHz. It mainly provides wireless Internet services, so it is often seen in devices that […]

Bluetooth uses the FHSS (Frequency Hopping Spectrum) method, which usually hops 1600 times per second and divides the 83.5mhz frequency band into 79 frequency band channels, each occupying only 1MHz of bandwidth. The modulation method is GFSK (Gaussian Frequency Shift Keying), and the communication distance to wireless data and voice is generally 10 meters. The […]

Wifi and Bluetooth are currently the most widely used wireless transmission protocols. For different places, we have different ideas about their use. Wifi is used more on the Internet, while Bluetooth is used for local area networks. For our face-to-face file transfer, Bluetooth is a faster wireless transfer than wifi. Wi-Fi is a technology that […]
