More than that, each device can also be under the jurisdiction of network Piconet with several network พร้อมกันอีกด้วย. Radio transmission technology of Bluetooth is used to change the jump frequency (Frequency hop).The channel is divided into several frequency small. During the channel frequency uncertainty makes can escape the signal disturb intervene have Bluetooth will use frequency in contact area. ISM, (IndustrialScientific Medical), frequency 2.4 Giga เฮิรต์ and low power consumption. By practice, and equipment of Bluetooth is การใช้งานไม่ area over 10 meters. The contact through the channel supports both data (asynchronous) and voice (synchronize) ที่ความเร็ว 741 Kbps.Can manage multiple devices can communicate at the same time. The device serves as a master and other devices acting as a slave in integration of equipment is a network of Bluetooth. We call piconet.Piconet could have equipment that communicate all 8 pieces, one is master and slave at least one. The communication is the point to many points. The channel and bandwidth is split between devices in piconet
.Wi-Fi vs. Bluetooth
inexperienced users are often confused with the technology 2 this always, despite the fact the two technologies are designed to use very different. Although both are used in the same frequency band is 2.4GHz anyway, we now get to know each technology first Wi-Fi (or 802.11 A / B / g) is a standard that allows you to connect to the Internet, wireless home or สำนักงานได้ using equipment such as Wi-Fi. Router etc. (also present are open to the public, the wireless accessHot Spot places extensively), wireless connection technology will work Wi-Fi radius covers up to 100 feet. (about 30 meters) from the device.If 802.11b is a maximum 11Mbps while if as standard 802.11g can connect at a speed of up to 125Mbps which at this level is equivalent to the connection. Ethernet 100Mbps used on office network ever
.Bluetooth is a technology for the personal area network The radial function quite close, such as just within the same room. There is also a connection speed, lower as well (771 Kbps for Bluetooth and 1.x 2.1Mbps for Bluetooth 2.0) is designed. To connect the work between devices such as wireless keyboard, mouse, headphones, and a printer. Collect computer, Pocket PC And mobile, so connected with the Bluetooth.It also doesn't need routers. Because the connection between the device with the device. The maximum support simultaneous connections 8 together, however, Wi-Fi(Peer-to-Peer ad-hoc network), but most are connected through the router
