30 Wi-Fi: It is a network standards Determines how two wireless devices communicate to each other. Over the air Communicate with each other is important. Faster data transfer is expected Many computers and devices can connect in one time. 30

31 Bluetooth: It determine the way Bluetooth devices communicate with each other. They use short-range radio waves to transmit data. It is just for limited data transfer between two devices, It can transfer data among devices without any cable or wire. Jadi, Jimat Cable la kawan kawan!! 31

32 WiMax: Wide Interoperability for Microwave Access, It is developed by IEEE: "Institute of Electrical and Electronics Engineers." Its job is to specify how wireless devises communicate in a wider area. WiMax provides wireless broadband Internet access. 32

33 Network Communication Standards 33

34 Network Communication Standards A single station can serve hundreds of users Weather conditions like rain can interrupt the signal 34

35 WAP Wireless Application Protocol Determines how wireless devices like smart phones and PDA's can show contents of Internet 35
