Agus Majidi sighed with relief when he finally got his own Internet connection. As a university student, he was pleased that he would no longer have to go to an internet kiosk (warnet) but could now use a CDMA modem, Venus VT-12, to surf the Net from his lodgings. By paying Rp 375,000, he was satisfied with the modem manufactured by Fren, which has a speed of 230.4 Kbps – faster than the cable modem and Wi-Fi (64 Kbps) or PSTN modem (56 Kbps).
Today, not only Fren but also other operators are involved in the data communication business. Although some companies do not find the business too profitable, it is growing at a rapid pace.
Smart Telecom, for example, sells cell phones that can also function as Internet modems with a subsidized subscription rate. However, Smart Telecom still finds it possible to make money with its subscription rate. “Our records show a significant increase in sales,” the West Java Regional Commercial head of PT Sinar Mas Telecommunication (Smart), Jabar Antony Pandapotan, told detikcom.
As a result, data usage has shown an increasing trend over the past year. However, he admits that at peak hours, such as lunch or dinner time, the network experiences some connection trouble or delays at several locations. That is the natural tendency of wireless connections, either CDMA or even GSM, in that the network becomes congested during peak hours when there are many users.
Information data communication is a process of sending and receiving data and information from two or more devices, such as computers, laptops, printers or other communication devices, which are connected within a network, both either on local or on a wider network, like the Internet.
Generally, there are two types of data communication: terrestrial infrastructure and satellite. Terrestrial infrastructure uses cable or wireless for access. This type involves a large investment. Some of the services included in terrestrial connection are: Direct Data Connection (SDL), Frame Relay, VPN Multi-Service and Data Package Communication Connection (SKDP).
Meanwhile, data communication via satellite usually covers a larger area and can cover areas where it is not possible to construct terrestrial infrastructure, although it takes longer for the communication process. The weakness of the satellite type is disturbance from sun radiation (sun outage). The worst disturbance occurs once every 11 years.
The main problem with both types of data communication is limited bandwidth, which of course can be expanded. Access through satellite usually experiences a propagation delays so terrestrial infrastructure has to be built to strengthen it.
With all the plus and minus points, all operators offer various attractive packages. Telkomsel, for instance, offers a package called Telkomsel Flash. Using a slogan offering unlimited use, customers are rushing to switch to the Telkomsel package, which has a daringly low rate, starting from Rp 125,000 with data access up to 256 kbps for the first 3 GB. The balance of the “unlimited” offer is up to 64 kbps.
