New Technology of 3G

Later this technology, WiMAX has become the excellent debate and discussion among both vendors and telecommunications operators worldwide. With more than the ability of BWA technologies (Brodband Wireless Access) before WiMAX becomes one of the rival 3G (cellular systems to next-generation-3) to meet customers' needs will be high-speed access.

With WiMAX munculya automatically will cause competition between pengusung WiMAX vendor with the 3G bearer. Each race shows the mutual benefits of both capacity and related technologies, services, investment (economic value) and in ease of use and maintenance. As many countries have been known to implement a 3G technology (still trial) but for WiMAX is still in the process of certification. Even if there are still using the pre WiMAX technology.



Many key factor for successful implementation of a technology. Thus the very need to be sure that the operator will operate the WiMAX technology, or 3G. Article at a glance, the description below is a comparison between WiMAX technology and 3G technology. Of course, in the evaluation process required a sharp study of the deeper aspects of the technical and economical aspects. In addition, studies need to be between incumbent operators and new service for.

3G Technology

3G services is a communication service that promises to move the increased bandwidth of up to 384 Kbps when accessed in the running (nomadic), while in the vehicle moving speed is around 128 KBps to 2 MBps and when in the silent condition. The technology can be used to provide 3G services can be based on GSM (W-CDMA) or CDMA (CDMA2000). However, because from the beginning of the 2G technology in its system is dominated by the GSM to 3G is currently also developing many of the W-CDMA technology. Among the 3G technology is also referred to compete between the GSM and CDMA-based.
following description of the evolution of cellular technology (GSM & CDMA) to 3G.
Evolution to 3G Cellular System

WiMAX technology

Meanwhile, WiMAX is a technology that is new. Even some of the test device from the vendor to get the certificate "WiMAX" new start around August 2005. Standards for mobile WiMAX (IEEE 802.16e) passed around a new mid-year 2006. Sementaa that WiMAX will be developed at this time still comply to IEEE 802.16-2004 standard that applied to fixed solutions.

Whereas in the beginning with the WiMAX technology standard 802.16 and then update to 802.16 (REVd) and developed to serve customers for mobile (802.16e). The following table explains the various standards in the evolution of WiMAX.

Development of the WiMAX Standard

Product Life Cycle

As usual on the implementation of a technology or product then the chain of the product life cycle will be referred through the 4 stages of product development, introduction to market, Mature Market and product phase-out.

The difference between WiMAX and 3G at this time is that to enter the WiMAX tahapannya new product development and introduction to current market. Meanwhile, 3G is being a 2-step introduction to the market and mature market (for some countries).

Phase to product phase-out would still not known, need to be more in-depth study related to the time (how many years) the two technologies can survive.

Following picture describe your product Life Cycle between WiMAX and 3G technology.

Life Cycle WiMAX & 3G

Service

When viewed from the service (speed) that can be given, then the WiMAX over 3G capable. The table below is taken from CSBF research that describes the comparison of various technologies, including future 3G and WiMAX.

Comparison of data rate (speed) between WiMAX & 3G

Thus, the benefits of WiMAX is seen from the speed. Thus, it automatically provides many services that interesting compared to 3G.

However, when focused on its ability Mobility, 3G is still superior compared to WiMAX. Moreover, at this time (2005) focused on the new WiMAX subscribers fixed and start the new year 2006 focused on moving customers (nomadic).

Mobility between the 3G vs WiMAX

According to the description above, WiMAX is ideal for low Mobility conditions but high bandwidth. While 3G is high for Mobility with a low data rate.

Besides the differences in the top from the start, including 3G mobile technology is for personal customers. With the WiMAX technology was originally implemented for backhaul and broadband access. To the front after the standard WiMAX 802.16 e new applications suitable for mobile (nomadic).

How do in Indonesia?

Special two-in technology to both WiMAX and 3G is still not defined and the frequency of the service who is entitled and how can MHz. Cases the application of 3G is still waiting for a long time. Long service to the new trial is Telkomsel and Indosat, while a new operator that has been holding a 3G license Natrindo and Cyber Access Communication (CAC). Meanwhile, in the regulation of its own WiMAX inform new application possibilities in the range of 2.3 GHz band, 3.5 GHz and 5.8 GHz. Exact frequency and the name of the operator has not been determined.

Conclusion and Suggestions

- WiMAX is suitable for customers with a low level of mobility but the high bandwidth needs.

- 3G subscribers with a focus on the mobility needs of high level while the lower bandwidth needs.

- From the time to market compared to 3G precede WiMAX.

- In perkembanganya developed for 3G customers, while personal WiMAX originally developed for bachaul, access, new to the personal.

- Keep right provisions of the government related to the frequency of WiMAX and 3G.
