The development of Internet technology continues to happen and we can not fight it, now munculah lately several social networks like facebook, twitter, blogs, and its users continues to increase with time. Internet is the interconnected-networking, a series of computers connected in a few series. Internet contained in a common computer system, which connect globally and using TCP / IP as the protocol exchange of packets (packet switching communication protocol.) The series of the largest Internet called the Internet while connecting the circuit with kaedah is called internetworking. There are two common forms of Internet access, ie dial up, and jalurlebar. In Indonesia as developing countries where Internet access and penggunhaan PC is still too low, others mostly from Internet access through public facilities such as Internet cafes, cybercafes, etc. hotspots. Other public places are often used for Internet access is a campus, offices, cafes, shopping malls and hotels region contained the hotspot area to access the Internet. Besides using a PC, we can also access the Internet through Mobile (HP) using a facility called GPRS. GPRS is a wireless communication standard (wireless) that has a connection speed of 115 kbps and supports broader applications such as graphics and multimedia. GPRS technology is accessible to support the facility. To set up GPRS on your phone depending on the operator (Telkomsel, Indosat, XL, 3) the use and Internet access fees are calculated through the amount of capacity (per-kilobite) that are downloaded.

In Indonesia, the estimated number of Internet users has reached 25 million people. Of these, the most dominant Internet users in Indonesia comes from teenagers. If previously we had to find cables and plugs to connect to do Network (LAN), then with WiFi we do not have to bother looking for the cable, but just enough to find the signal. Technically, WiFi is one variant of communications and information technology that works on the network and the WLAN (wireless local area network). Wi-Fi is short for Wireless Fidelity, which has a sense of cecum collection of standards used for Wireless Local Network [Wireless Local. Area Networks – WLANs) based on IEEE 802.11 specification. Latest from the 802.1 standard specifications or b. He such as 802.16 g, is currently in preparation, the latest specification will offer many improvements ranging from a more extensive coverage to the Far transfer speed. Wi-Fi devices are not only able to work on WLAN networks. but also on network Wireless Metropolitan Area Network (WMAN). No wonder the Wi-Fi technology makes even more public interest-particularly among the community of Internet-for internet-without wires. Because the Wi-Fi technology at least provides an easy access. This means that users in one area can access the Internet simultaneously without having to be bothered with cables. Consequently, users who want to do surfing or browsing news and information on the Internet, simply bring the PDA [Pocket digital assistance) or Wi-Fi enabled laptop into a place where there is access point or hotspot. The proliferation of hotspots in places such built by telecom operators, Internet service providers and even individual triggered the second factor, namely because construction costs are relatively cheap.

Increasing the quantity of Internet users based on WiFi technology is increasingly rampant in various parts of the world, has encouraged ISPs to build hotspots like those in big cities of the world. In Indonesia alone, the use of Internet-based Wi-Fl already implicated in several major cities. Today, VoIP-based telephone business (\ / olce over Internet Protocol) has also been using Wi-Fi technology, in which phone calls are forwarded through the WLAN network. The application is named VoWi-FI. Some time ago, the latest technical standards created by the IEEE has been able to support the operation of a streaming video service. Even the predictable, the future can be made based card WI-FI technology that can be inserted into electronic equipment, ranging from digital cameras to video game consoles. Wireless in the Indonesian language is called a wireless, is a technology that connects the two devices to exchange data or voice without using a cable media. Data exchanged via the media of certain light waves (such as infrared technology in the TV remote) or radio waves (such as bluetooth on the computer and phone) with a specific frequency. The advantages of this technology is to eliminate the use of cables, which can be quite disturbing in aesthetics, and also the complexity of installation to connect more than 2 devices simultaneously. For example: for connecting a first computer server with 100 client computers, it takes at least 100 pieces cable, length varies according to distance from the server the client computer. If the cables are not covered through a special lane, this can interfere with views of the eye or the interior of a building. This unpleasant sights not found in the relations between the wireless technology devices. Disadvantages of this technology is the possibility of interference for each other wireless connection on other devices. One example is the Internet mobinity wireless Internet. Internet with a network of Telkomsel. mobinity Internet provides unlimited internet facility.
