Bluetooth and WiFi wireless connection which is most needed for mobile devices

Bluetooth and WiFi wireless connection which is most needed for mobile devices? Bluetooth and WiFi who better to use? WiFi-enabled mobile interconnecting devices with the basic application of the above Bluetooth and WiFi features, users are likely to have some confusion. Of course, we see from the surrounding common application environment, WiFi usage frequency is larger than the Bluetooth function application. WiFi and Bluetooth is the use of more than two kinds of wireless connection, today is mainly said that the two wireless connection have what characteristics and advantages.

Bluetooth devices: Low power consumption

Bluetooth in 2. 4GhzISM (Industrial, scientific, medical) frequency band, transmission rate of 1Mbps, transmission distance of about 10 meters, as long as the two can support Bluetooth communication equipment, in the transmission distance to achieve data transmission. It started in the mobile phone application is very extensive, Bluetooth headset for a long time is also very popular, but found that my phone's Bluetooth function has not been used once.

Some time ago, the Bluetooth Technology Alliance released 4. 0 Technical Specification, main low power performance, with the introduction of two new trademarks of Bluetoothsmart and Bluetoothsmartready, Bluetooth will interconnect all Bluetooth-enabled devices and connect up to the computer, thereby connecting to the entire Internet. The future of Bluetooth technology will be deep sports and health care industry, Bluetooth transmission makes the usual data more easily accumulate, analysis and use of the future application of the bright spot.

Bluetooth is a kind of radio technology which supports the equipment short distance communication (in general 10m). Can be in the mobile phone, PDA, wireless headset, notebook computer, related peripherals and other devices for wireless information exchange between. "Bluetooth" technology can effectively simplify the communication between the terminal equipment of mobile communication, and can also successfully simplify the communication between the device and Internet, thus the data transmission becomes more and more efficient and the road is widened for wireless communication. Bluetooth uses decentralized network structure and fast frequency hopping and short packet technology, support point-to-point and point-to-point communication, working in the global 2. 4GHzISM (ie, industrial, scientific, medical) frequency bands. Its data rate is 1Mbps. The full duplex transmission is realized by the time Division duplex transmission scheme.

WiFi wireless connection: hot spots

WiFi at 2. 4Ghz band work, the maximum speed of support up to 54Mbps, through the Internet connection installed access point to create, the transmission distance of about 300 feet. As long as you have a WiFi-enabled device on hand, you can connect to the hotspot area at any time. It is now widely used in PCs, tablets, mobile phones and other devices, has become the most familiar short distance communication methods.

But its security is also widely suspected, in many places where WiFi hotspots are free, many people are concerned about whether their data will be compromised, but even with this concern, WiFi is increasingly being introduced into public places to provide a convenient, inexpensive choice of web portals. As long as the security is resolved, it will become an optimal networking option.

WiFi is a technology that allows computers, handheld devices such as PDAs and mobile phones to be connected wirelessly to each other. Wi-Fi is a wireless network communication technology brand, held by the Wi-Fi Alliance (wi-fialliance). The aim is to improve based on IEEE802. 11 interoperability between standard wireless network products. At present, the average person will have Wi-Fi and IEEE802. 11 confused. Even the Wi-Fi equivalent to the wireless internet.

In addition to the above two Bluetooth and WiFi wireless connection mode, there are ZigBee, NFC and other wireless connection categories. In fact, they have advantages, different ways of connecting to different fields, therefore, can not say that one will replace the other, they are complementary role.
