Question

Differents betwwen the bluetooth zig bee and wifi

Answer 1

ZigBee:- IEEE 802.15.4-2003 (Low Rate WPAN) deals with low data rate but very long battery life (months or even years) and very low complexity. The standard defines both the physical (Layer 1) and data-link (Layer 2) layers of the OSI model. Basically used in RF TV remotes and has very very low data rates and range.

Bluetooth:- based on IEEE 802.15.1, defines physical layer (PHY) and Media Access Control (MAC) specification for wireless connectivity with fixed, portable and moving devices within or entering personal operating space. Range is limited and data rates can go from 1.2 Mbps for commercial (mobile Bluetooth) to 10 Mbps industrial/military purpose.

WiFi:- IEEE 802.11, basically is a wireless LAN, its works similar to that of LAN but has wireless connectivity. The range is limited from few 100 meters to max 500 meters.

Answer 2

The main difference is that Bluetooth is primarily used to connect devices without using cables, while Wi-Fiprovides high-speed access to the internet. Bluetooth is a wirelesstechnology standard that is used to exchange data over short distances (less than 30 feet), usually betweenpersonal mobile devices
