Abstract

This paper elaborated the performed analysis on the differences between GSM network and CDMA network in technology. As we know, the advances in technology is very fast, because some people will be found new experience in their life. For example, the high-tech of communication that happened in the world, like mobile phone, television, computer and many others. This high-tech communication bring some network in the world.

Now, many people used some mobile phone to communication with each others. Because of this high-tech communication, in mobile phone there is a network. The name of the networks are GSM network and CDMA network.. In this case, there are some disadvantages and advantages from both of this network.

Keywords : GSM network, CDMA network, the steps, the advantages, the disadvantages.

Introduction

The advancement of information technology and telecommunications are starting gate toward human life which is better and more efficient as the effects of the knowledge developed by humans. In every years, Technology continues to grow rapidly in all fields. One of them in the field of communication. Long time ago, advance to communicate with each others are still difficulties, but with the development of science and technology, the problem of communication has not been a problem again. The need for convenience in communicating now very feels different from the ancients. As well as a way to send information from one person to another person.

Before the discovery of the telephone, people used to communicate in different ways, starting with the use of smoke, sending letters, until finally found a communication tool is the telephone. When a communication device such as telephone was invented by Alexander Graham Bell. It has not been recognized by most of the human race, but with the invention it turned out to be the beginning of the development of telecommunications eventually be developed rapidly as now.  The Cellular technology of development growing very quickly, so that the function of the phone is not in use as a communication only, with additions of features such as digital cameras, radios, high-resolution color LCD with mobile phones into devices that are sophisticated and smart.

In the first time, telecommunication devices still use the big cable complex and a lot, cables devices are still in use today but experts are still thinking of switching to mobile telecommunications and practical nature. And that's what the foundation and background for the progress of the development of wireless telecommunications (wireless / unguided). Wireless Communication Mobile is a tool which is communication without wires practically move with Mobile Device. This wireless technology has grown rapidly in the last decade. Principle of wireless communication using a separate radio channel for communicating with the cell site.

           And now, phone networks are more advanced. But not many people know about the mobile network they are using, including advantages and disadvantages of these networks, as well as the way of working of both the network. In this paper will explain the network used in the phone which is a CDMA network and GSM network.

Discussion

According Miarso (2007: 62), technology is a process that increases the added value, the process uses or produces a product, the resulting product does not separate from other products that already exist, and therefore an integral part of a system.

According Forsdale (1981), a expert of communication and education "communication is the process by the which a system is established, maintained and Altered by means of shared signals that Operate According to rules"

                 

                  Since the first time a mobile phone technology and mobile phones were introduced in Indonesia and the world, while it also appears the two types of networks are used in a mobile phone. The two types of the networks are GSM network and CDMA network. GSM and CDMA are two different kinds of technologies that support the functionality of a mobile phone, especially the phone functions and Short Messages Service (SMS) functions. The introduction of mobile technology based on GSM and CDMA, maybe this can be one of the introduction of mobile technology based on GSM and CDMA, maybe this can be one consideration if we want to buy a mobile device, because this time the mobile device is no longer used just to communicate, but has become fairly high mobility among those who are busy with the business.

1.                    Definition of GSM network and CDMA network.

a.    Global System for Mobile Communication (GSM)

      GSM itself is its own GSM stands for Global System for Mobile Communication. From the name it has been very clear, that GSM was deliberately created for the benefit of a wireless network using a mobile phone. At the time it was first launched en masse, working on GSM network frequencies of 900 MHz which is a second-generation communication system, or what we are familiar with the term 2G which can make access to the internet.

GSM itself is basically working with features timeslot, which is one of the developments of Time Division Multiple Access technology, which allows each user to be able to transmit data and information based on the unit divided by time. This makes each data packet will divided up into a particular timeslot. This timeslot is a slot that will be used by the GSM network for some time or temporary.

GSM technology is now highly developed, where many operator GSM entered into a 3G or third generation networks. The third generation of GSM system can allow a person to communicate better with voice, text and data, and has been widely used in Indonesia.

b.    Code Division Multiple Access (CDMA)

      CDMA itself is short for Code Division Multiple Access. This extension can be interpreted as a multi access can be achieved by using certain codes. Technically, CDMA network users will be using the unique code in order to access existing channels on the system. A unique code, means that every user will have codes that are different from each other.

CDMA itself was originally used for military radio communications system of the United States, which later in the 90 developed by Qualcomm that later patent. In 1993, serve as the CDMA digital cellular standard in the United States.

2.                    The Differences between GSM network and CDMA network.

a.    The Coverage of BTS

      Base Transceiver Station or BTS is a telecommunications infrastructure that facilitates wireless communication between communication devices and network operator. The first aspect that we can compare between GSM and CDMA coverage is area and also the number of base stations. Can be seen clearly, that extensive coverage of GSM base stations owned more than the CDMA. This is because some areas do not have many customers, so that in make development of CDMA BTS also declined. In addition, the popularity of GSM also increased the effect, why the number of base stations being owned by GSM is much more when compared to CDMA.

b.    The Roaming Capabilities.

Roaming is the process of changing the services of the Home Network to Other Network. The second aspect that we can compare the difference in GSM and CDMA are the roaming capability. Roaming is the ability of a telecommunications network in order to work in certain areas. Technically, GSM has a roaming capability, which makes GSM can be used anywhere in the region in the area of Indonesia, in general.

Different from the GSM, CDMA can not always be used freely. Because when you use CDMA-based network then you will incur additional costs, which is the cost of roaming. To avoid this, it is usually some CDMA network operator will introduce service features combo to avoid roaming, which enables a number of CDMA operators have the same number as the GSM number, so it is not affected by roaming.

c.    The Number of Users.

If we see based on the number of users, then it is definitely GSM is the most widely used operator in Indonesia, even the world, especially Europe. This makes a lot of GSM operators to develop and expand its footprint to all corners. The opposite of the operator GSM, CDMA has far fewer users when compared to GSM. This makes many CDMA operators can not compete, and is currently living a few who survive in the competitive mobile operator in Indonesia, even the world.

d.    The Prices Devices and Systems Services.

If we look into the difference of investment costs to be incurred, then it certainly will affect the cost of the device and also the cost of the cellular network system services. CDMA has a low investment cost will cause the device to a mobile phone which operates in CDMA networks have a cheaper price. One concrete example is the popular Apple phone, iPhone 4. There are two variants, which is CDMA and GSM. In terms of price, CDMA iPhone has a price much cheaper than the GSM version. In addition to the price of the device, the subscription fee and other costs associated with the implementation of the CDMA network will be much cheaper than the GSM.

e.    The Cost of Investment.

Differences between cellular networks GSM and CDMA also this can also be seen from the investment costs incurred. The investment costs incurred for the implementation of a mobile network system using a code or CDMA technology is much cheaper when compared to GSM. It due to the implementation of CDMA networks tend to be easier and more simple, then of course it will affect the cost of the investment.

Not only that, the greater the ordinary issued it will get better internet signal is received, such as data packets. The data packet itself into lanes for entry and exit of data when connected to the internet, which is then transmitted in the network either using a cable or wireless. This is called the working principle of the network in general are different only in their use of media.

3.                    The Similarity between GSM network and CDMA network.

a.    The Quality of Network and Signal in Residence.

      The quality of network at the location where you live can also be a consideration. If it turns out that a good network quality in the neighborhood where you live is a CDMA cellular network, then you can use the CDMA to the needs of your home, such as the use of a modem and telephone everyday. GSM and CDMA equally be used as a modem device is minimalist and flexible, because just by using the USB port. USB modem function model is very often used by students, especially for students.

b.    The Functionality.
        In terms of functionality of GSM and CDMA also could be an option, as both have almost diverse functionality. However, for stability and also coverage, may GSM slightly superior when compared to CDMA. However, CDMA has good signal, and also the security of data which is also very good, especially for electronic transactions. Therefore, for users who require security and comfort when performing data access, perhaps CDMA network could be your mainstay.

Conclusion

Communication technology will continue to evolve with the times and the increasing human need for communication more practical. It also must be balanced with the knowledge of the technology, at least be able to keep up with technology and developing era. The nature of data communication, there are several elements that a communication process can take place properly. These elements may be, the source of data, media and data receiver. In the data communications, the medium used is wired and wirelessly.

The communication channel without Cable (Wireless), such as GSM, CDMA, and cellular phone. Satellite is part of the LAN, which itself is a wireless internet connection from one device to another without using cables. While the satellite is a relay station (amplifier) that transmits microwave signals over great distances.

.Today, mobile communications play an increasingly significant role in meeting the needs of telecommunications, especially mobile systems. Currently the number of telephone users reached ± 1 billion and this figure exceeded the number of fixed telephone network users. So at that time the wireless communication would be the capital of the dominant access technology.
