Type Speed ​​Internet Access


Type Speed ​​Internet Access - Access speed will depend on the network technology around the distance and distance / environmental conditions when the internet connection is made. The development of information and communication technology today allows us to connecting computer to the Internet in some way. There are several types of options / type internet speeds that can be used. Here is the internet speed in accordance with the selected channel. Dial-Up connection (via the PSTN Line) Before there were mobile, communication is generally done through telephone lines. We can access the Internet by connecting the computer to the home telephone wiring via analog modem (conventional). This method is often referred to as a dial up connection. Dial-up via the PSTN (Public Switched Telephone Network) is the way we connect to the ISP (Internet Service Provider) via the regular telephone network (PSTN), for example, is "Instant Telkomnet" from ISP Telkom. ADSL connection ADSL (Asymetric Digital Subscriber Line) is a modem technology that works at a frequency between 34 kHz to 1104 kHz. This is the major cause of data transfer speed difference between an ADSL modem with a conventional modem (that works at frequencies below 4 kHz). ADSL advantage is to provide the ability to access high-speed internet and voice / fax simultaneously (on the customer side by using a splitter to separate the telephone line and a modem line). What is the maximum bandwidth that is obtained when we use internet access using ADSL: For a 384 kbps line rate, maximum bandwidth obtained close to 337 kbps. For a 384 kbps line rate, average throughput (speed donlod) that can be obtained about 40 Kb / s. For a line rate of 512 kbps, which is obtained close to the maximum bandwidth of 450 kbps. For a 512 kbps line rate, average throughput (speed donlod) that can be obtained about 52 Kb / s. Examples ADSL connection is "Speedy" from Telkom. Compared to dial-up connections, ADSL connections much more rapidly that many are turning to service this connection. GPRS connection In theory GPRS promises speeds ranging from 56 kbps to 115 kbps, allowing Internet access, transmission of multimedia data to a computer, notebook and handheld computers. However, in its implementation, it depends on the following factors: The configuration and allocation of time slots at BTS level Software used Support features and mobile applications used This explains why at certain times and in certain locations GPRS access was slow, even slower than the access CSD which has a speed of 9.6 kbps. 3G connection 3G network is not an upgrade from 2G; 2G operators affiliated with 3GPP need to replace many components to be able to provide 3G services. While the 2G operators that are affiliated with the 3GPP2 technologies easier to upgrade to 3G because of its various network element has been designed for the direction of broadband wireless services (wireless broadband). Telecom mobile phone network has increased towards the use of 3G services from 1999 to 2010. Japan is the first country to introduce 3G nationally and transition to 3G in Japan already achieved in 2006. After Korea became the first adopters of 3G networks and the transition has been accomplished in the early 2004 and lead the world in the field of telecommunications. HSDPA In a crowded office environments users can enjoy streaming video with an estimated speed of 300 Kbps. Excess HSDPA is to reduce delays in downloading the data (delay) and provide faster feedback when the user uses interactive applications such as mobile office or high-speed Internet access for use of the facility to download games or audio and video. Another advantage HSDPA, increase system capacity without requiring additional frequency spectrum. This leads to reduced costs of mobile data services significantly. WiFi Wi-Fi (Wireless Fidelity) is a wireless connection such as mobile phones by using radio technology, so users can transfer data quickly and securely. Wi-Fi not only allows you to access the Internet, Wi-Fi can also be used to create a wireless network in the company. Because of that many people associate Wi-Fi with "Freedom" because Wi-Fi technology gives freedom to users to access the internet or transfer data from the meeting room, hotel room, campus, and cafes are marked "Wi-Fi Hot Spot". Also one of the advantages of Wi-Fi is practicality, no longer need to install the cable network. For the problem of speed depending on the signals obtained. Wireless Broadband Broadband Wireless Access also called still acceptable in a vehicle speed of 60 kilometers per hour. WiBro was developed jointly with Samsung Electronics and Technology Research Institute (ETRI) and has received a certificate from the WiMAX Forum. This technology is able to transmit data at speeds up to 50 Mbps. Data transfer speed is able to outperform the data transfer speed of HSDPA platform that has the ability to send data up to 14 Mbps. LAN Commonly abbreviated Local Area Network LAN is a computer network that the network only covers a small area. Today, most LAN based on the IEEE 802.3 Ethernet technologies using a switch device, which has a data transfer speed of 10, 100, or 1000 Mbit / s. In addition to Ethernet technology, the current 802.11b technology (commonly called Wi-Fi) is also often used to form a LAN. Cable TV In the home network, the cable from the "cable" used coaxial cable and installed a "dividing line" (splitter) cable. After the cable from the network (cable network) past the splitter, cables channeled into two channels, one for TV and one to the cable modem. From the new cable modem to the Ethernet card and then to the computer.
