Nowadays, information comes and goes in the air. That is because analog change to digital. We can say that the wireless revolution is coming to worldwide. There are portable media and computing platforms such as cell phones, smartphones, and wireless-enabled personal computers. For example, smartphones such as the iPhone, Android phones, combine the functionality of a cell phone with that of a mobile laptop computer with Wi-Fi capability. This makes it possible to combine music, video, Internet access and telephone service in one device.
I am going to introduce infrastructures of wireless revolution. First, Bluetooth is wireless networking standard, which is useful for creating small personal area networks. Wire-less phones and computers using Bluetooth communicate with each other, and operate without direct user intervention. Bluetooth is low power requirements, so it is good for battery-powered handheld computers or cell phones. Although Bluetooth lends itself to personal networking, it has uses in large corporations.
Second is Wi-Fi. It is wireless LANs and wireless Internet access. In most Wi-Fi communication, wireless devices communicate with a wired LAN using access points such as router and hotspots. Wi-Fi is popular to use because it is high-speed wireless Internet service. The problems of Wi-Fi are security features, witch make it vulnerable to intruders, and susceptibility to interference from nearby systems such as microwave ovens, or other wireless LANs.
Third is WiMax. WiMax is a family of standards developed by IEEE. It has huge wireless access range of up to 31 miles. (Wi-Fi is no more than 300 feet) And, it has powerful and high-speed Internet connections.
Next is Radio Frequency Identification (RFID). It is a system provides a powerful technology for tracking the movement of goods throughout the supply chain. It uses tiny tags with embedded microchips containing data about an item and its location to transmit radio signals over a short distance to RFID readers.
