Type connection

Type connection to the internet without wires (wireless)
1. GPRS (High Speed ​​Internet Access-GPRS)
Of course you know the phone (HP) is not it? The need for mobile communication industry will be one of the causes of GPRS data communications technology that is widely used today. GPRS stands for General Packet Radio Service which voice and data communications are performed using radio waves. GPRS has the ability to communicate data and voice at the time of mobile communication devices (mobile).
GPRS system can be used for data transfer (in the form of data packets) that are associated with e-mail, image data (MMS), and search (browse) the Internet. GPRS service is installed on your phone type GSM and IS-136, although the current GPRS network apart from GSM.
In theory, GPRS promises speeds ranging from 56 kbps to 115 kbps, allowing internet access, multimedia data delivery to computers, notebooks and handheld computers. However, in its implementation, it depends on the following factors:
Configuration and allocation of time slots at the level of BTS
Software used
Support mobile phone features and applications that are used
This explains why at certain times and in certain locations GPRS access is slow, even slower than the speed of access to CSD which has 9.6 kbps.
2. 3G (3G-Speed ​​Internet Access)
3G (read: triji) is an abbreviation of the term in English: third-generation technology. The term is generally used refers to the development of wireless telephone technology (wireless).
3G as a wireless solution that can provide access speed:
Amounted to 144 Kbps for fast-moving conditions (mobile).
Of 384 Kbps for running conditions (pedestrian).
Of 2 Mbps for static conditions somewhere.
3G network is not an upgrade from 2G; 2G operators affiliated with 3GPP need to replace a lot of components to be able to provide 3G services. While 2G operators affiliated with 3GPP2 technologies easier to upgrade to 3G because of its wide range of network elements in the direction it was designed for broadband wireless services (wireless broadband). Telecom mobile phone network has increased towards the use of 3G services from 1999 to 2010 Japan was the first country to introduce 3G nationwide and transition to 3G in Japan has been achieved in 2006 after the Korean became the first adopters of 3G networks and the transition has been achieved in the early in 2004, lead the world in the field of telecommunications.
3. Wifi (speed Internet access-WiFi)
Have you ever seen a wireless communication connection? The technology known as wirelless Fidelity (WiFi). Wireless network technology uses high frequency is at 2.4 GHz spectrum. Wi-Fi has a standard set of terms that are used for Wireless Local Networks (Wireless Local Area Networks - WLANs) based on IEEE 802.11 specification. The latest standard of 802.11a or b specifications, such as 802.16 g, is currently in preparation, the latest specification offers many improvements ranging from broad coverage even further up the transfer speed.
Wi-Fi (Wireless Fidelity) is a wireless connection such as mobile phones using radio technology, so users can transfer data quickly and safely. Wi-Fi not only can be used for internet access, Wi-Fi can also be used to create a wireless network in the company. Because of that many people associate with the Wi-Fi "Freedom" because of Wi-Fi technology gives freedom to users to access the internet or transfer data from the meeting room, hotel room, campus, and the café is marked "Wi-Fi Hot Spot". Also one of the advantages of Wi-Fi is practicality, not to bother installing network cable. For the problem of speed depending on the signals obtained.
