Cellular : Cellular Technology Timeline


4G mobile communication technology being so hot topic considering its application relatively new in Indonesia. But actually, there is not merely a technology 4G. There are a number of other technologies that preceded until he could reach that stage.

As summarized KompasTekno from various sources, communication technology Wireless stems from 1G or first generation. The technology is then developed into 2G, 3G to 4G as we know it today.

1G

The first generation or 1G introduced begin 1970s. Do not imagine had no internet connection at this stage communications technology. 1G technology work utilizing analog signal transmission. At that time, the technology is only can be used for phone calls only.

1G phone size was relatively large, compared with today’s mobile phones. Examples phones Motorola DynaTAC are quite popular in his time. phones that This was made in the period 1984-1994 has weight 794 grams. With a weight of nearly one pounds, weight DynaTAC almost equivalent to the weight of the Ultrabook.

The appearance of the 1G technology also plays a major role in promoting growth mobile phone market. Quoted KompasTekno of Bright Hubu, market share mobile phone while it grew from 30 to 50 per cent in each year. Even in 1990, 1G technology users around the world almost reached 20 million.

2G

1G technology continue to be used until replaced by 2G technology. The Difference The main difference between the two technologies is the use of radio signals. 1G using analog signals, while the 2G using a digital signal.

Phones that use 2G technology was introduced in 1990. During Mobile which is already implementing this technology can be used to send and receive data in small size. The point here is the data in text messaging (SMS), picture messages and multimedia messages (MMS).

2G technology itself is primarily made for voice and data connections tends to be slow. Updates on the network is then led to the term 2.5G and 2.75G.

The term refers 2.5G 2G communications technology combined with General Packet Radio Service (GPRS). In theory, the speed of transfer data using this technology can reach 50 kbps.

Furthermore, the term 2.75G is a 2G communications technology combined with standard Enchanced Data Rates for GSM Evolution (EDGE). In theory, data transfer speeds exceeding 2.5g, which is maximal at 1 Mbps.

3G

Standard implementation of GPRS in 2G communications technology paves the way for access faster data. Selepasnya, emerging technology known as The third generation or 3G in 1998.

3G communications technology is also known as the first mobile broadband. designation it arises because of the ability to access the Internet and can be used as Internet connection through a cable replacement.

In addition to data transfer speed that makes internet access quite smoothly, This technology already allows the use of activities related to the transfer audio, graphics and video. In short, the communication technology has able to use streaming video or a video call.

The International Telecommunication Union says that this 3G technology expected to bring a minimum data transfer speed of 2 Mbps for users which are stationary or walking, and 348 kbps when on the move in high speed. It was not clear by default how the maximum speed which is expected.

Slowly, 3G communications technology was developed to transition to The fourth generation or 4G. Technology in the transition period known as 3.5G and 3.75G.

3.5G technology is also known as High Speed Packet Access (HSPA). on stage this, the data transfer rate increases to a maximum of 14 Mbps download, and upload speed of 5.76 Mbps.

The technology is then developed into a 3.75G or HSPA +. in theory, telecommunications networks that implement this technology can obtain download speeds up to 168 Mbps and upload up to 22 Mbps.

The limit is a theoretical calculation, while users in a state will feel the real data transfer rates lower depending situation.

4G

The third-generation communication technologies can be added The fourth generation or 4G. There are two designations for the 4G communication technology currently known. The first is the Long Term Evolution (LTE) and Long Term Evolution-Advanced (LTE-A).

LTE technology, theoretically offering download speeds (download) up to 100 Mbps and upload speed (upload) up to 50 Mbps. The speed can be fast again, depending on the release of the technology used by the operator. despite Of so, LTE is still labeled pre-4G technology.

Labeling is due to offer LTE theoretical speed yet achieve the 4G standard of the International Telecommunications Union-Radio communication sector (ITU-R). The international organization issuing International Mobile Telecommunications-Advanced (IMT-A) which contains terms a 4G communication technology.

The requirement states that a 4G technology must have the speed 1 Gbps maximum download and upload a maximum of 500 Mbps.

While LTE is often referred to as 4G by mobile operators, yet achieve these requirements. Based on proficiency level, the LTE-A technology who encouraged to emerge as a True 4G technology.
