STUDI KOMPARATIF ANTARA HIGH SPEED CIRCUIT SWITCHED DATA (HSCSD) DAN GENERAL PACKET RADIO SERVICE (GPRS) PADA SISTEM TELEKOMUNIKASI TELEPON BERGERAK

At telecommunications system in industrial world of mobile cellular and

multimedia nowadays become development focus. Two technology which have

some years lately very direct having an effect on to life of many people is mobile

cellular and internet. Internet give amenity in accessing cheap and worthwhile

information, not depend on location and anywhere can access internet. While

mobile cellular connect distance which so far to communicate. Step following

logical is to bring both this technology together, enabling to access information

which not even depend on source of information but nor depend on location where

consumer can use the technology.

This time civilian even also have used to system evolution of cellular

divided become some generation. First generation started when system of cellular

still of uses technological analogue like AMPS, JDC and of NMT-450. While

second Generation started when system of cellular use digital technology and use

to access to duplicate more efficient in exploiting frequency resource that is a

period of/to GSM, CDMA and of TDMA. Later; Then afterwards all system of

cellular the have evolution go to third generation. However before going to third

generation all the system experience of change to second generation system after

beforehand.

From second generation technology to generation second of half, system

of GSM will do step to High Speed Circuit Switch Data ( HSCSD) first. This

system can deliver speed till 38.4 kbps. But only a few operator using technology

of HSCSD into network of GSM [all] operator. After era of HSCSD later; then

emerge General Packet Radio of Service ( more giving GPRS) of expectation. At

the (time) of early GPRS released that GPRS will be able to deliver data with

speed ± 115 Kbps.
