Cellular Term
LTE : (Long Term Evolution) is a name of high speed service that have high capability in mobile sistem comunication. LTE is a step towards 4th generation (4G) radio technology which designed to enhance the capacity and speed of the mobile telephone network. LTE is the successor of 3,5G (HSDPA). LTE will have data transfer speeds up to 600 Mbps.
HSDPA : (High Speed Downlink Packet Acces) is a HP priotocol that is often referred to as 3.5 G. Internet Access of HSDPA maximum is 14.1 Mbps
EDGE : (Enhanced Data rates for GSM Evolution) is next generation of GPRS technology develop. EDGE is also often called by the term 2.75 G. EDGE is faster than GPRS. Maximum speed transfer data can be done with EDGE technology is 473.6 Kbps.
GPRS : (General Packet Radio Service) is a internet acces technology which we known by the term 2.5G. GPRS has a data transfer speed over CSD technology. Maximum speed of data transfer from GPRS technology is 115 Kbp. Resistive Screen is a touchscreen display technology of Cell Phone where it works by tapping the screen, can use a finger or any object. Drawback to this is if the screen is placed on pocket (especially pants pocket), can be depressed, and caused the screen to be easily damaged because it is often depressed.
Capacitive Screen is a touchscreen technology that is a develop of resistive screen technology. How it works, the screen should be touch with a finger and can not use with other objects (nails, stylus, etc.) because these screens work by using electrical charges that exist in our body. Capacitive touch screen model is almost no significant weaknesses,
