The evolution of the cellular network, from 1G to 5G

Posted on

Believe it or not, now we can’t live without it smart phone? You can live, but it will be very difficult to communicate with others. Besides being cheaper because we can make calls and text calls without having to spend credit, smart phone It also makes it easier for us to find food, find places, find public transportation, watch movies, listen to songs and much more. Before technology was as advanced as we know it through smart phone, Mobile data networks have gone through a very long evolution. Find out, come on!

1G network

The first generation of network technology was introduced in the 1970s, but only became effective in the 1980s. This network works by transmitting analog signals and can only be used for voice communications, and can only be used for phone calls. The signal transmission speed is only 14.4 kbps. Examples of such analog network development are AMPS (Analog Mobile Phone System) developed in America and TACS (Comprehensive Access Communication System) developed in England. Try asking our brother or dad, did they have one before? cell phone Old school brand Ericsson or Motorola which looks similar walkie talkie?

2G network (GSM and CDMA)

This 2G network technology was introduced in the 1990s and already uses digital signals. In addition, this network can also be used to exchange text messages also known as SMS (short message services). The development of this network technology is GSM (Global System for Mobile Communications) and CDMA (Code splitting multiple access). In Indonesia, PT is the pioneer of GSM technology. Telkomsel and PT. Satlindo (Indosat). The difference between GSM and CDMA networks is broader coverage and network security. GSM has a wider network coverage, but CDMA has a higher level of network security. During the second generation of communication networks, GSM had a transmission speed of only 9.6 kbps while CDMA had a transmission speed of 154.6 kbps.

Garingan 2.5 grams (GPRS)

In this second and a half generation, data access technology can begin to be used in cell phone. Initially, this data access technology was developed into WAB (WAB).Wireless Application Protocol), but the market was not well received. Subsequently, data access technology evolved into GPRS (General Packet Data Radio ServiceIts transfer speed is up to 115 kilobits per second. Besides being able to contact Internet And the internal networkGPRS also allows users to exchange images and audio via multimedia messages (MMS).MMS Service). In addition, GPRS can also be used to transmit E-mailThe fax will also benefit from the servicee-commerce, e-commerce, And the Electronic Banking Services.

Well, in the age of GPRS, social media and apps already exist chat As you know, this is very popular among young people. The most popular social media at the time was Friendsterwhile the app chat Most preferred is mIRC, Yahoo Messenger and eBuddyAnd the Mig33.

JARINGAN 2,75G (EDGE)

GPRS network development is EDGE (Enhanced data rates for GSM evolution). The data transfer speed is three times faster than GPRS, reaching 384 kbps. EDGE was first introduced by AT&T; It is a company in the United States. Technically, EDGE already meets 3G speed standards, but in Indonesia, only a few mobile operators have developed this network.

3G network (WCDMA and EVDO)

3G network technology has been developed in both GSM and CDMA networks. On the GSM network, 3G was developed into UMTS (Global Mobile Communications Service) while GSM networks are called EVDO (Improve evolution data). Please note that the modulation technology used by UMTS is called WCDMA (Broadband CDMA), which is exactly what the term is better known than UMTS. Initially, UMTS data access speed was 480 Kbps and EVDO reached 2.4 Mbps. After further development, UMTS data access speeds now reach 2Mbps and EVDO’s 3.1Mbps.

Communication technologies that have emerged in the era of the third generation are: video call. In the past, people were not as easy as now if they wanted to use this calling service. Because it’s not all cell phone usable for video call.

3.5G network (HSDPA)

still in a program GSM cellular network, HSDPA technology appeared (High speed download access packages). This network is now used most often for activities Download And the Loading Multimedia on the Internet. HSDPA is an additional protocol in WCDMA whose data transfer rate was initially 4.1 Mbps. HSDPA transfer speed continues to grow, changing to a maximum of 14 Mbps (Loading) and 22 Mbps (Download). Meanwhile, in this third and a half generation, from EVDO a program CDMA networks are now getting faster to 14.7 Mbps (Loading) and 5.4 Mbps (Download).

Regardless of being used in cell phone, 3.5G network technology is also commonly used in portable modem To connect our laptop to the Internet anywhere and anytime.

4G network

ever heard jokes About the people who insist on buying 4G internet package but are still angry when they find out that the network is LTE? Well, actually LTE (long term developmentIt’s the same 4G data network. LTE speeds up to 100Mbps (Loading) and 50 megabytes per second (Download). In the era of 4G networks, culture flow More familiar in our daily life. In Indonesia, this 4G network technology is still under development by almost all cellular operators. That’s why not all places can access this 4G network.

5G network

Currently, 5G network technology is being developed and is expected to begin treatment in 2019 or 2020. It is estimated that this network speed is up to 10 Gbps, which is much higher than that of LTE. So far, many countries have tested the implementation of this network. The technology that will be increasingly developed in the later 5G era is VR (Virtual Reality(Dan A.I.)prosthetic care). Meanwhile, in Indonesia itself, we don’t know when 5G will start. Of course we have to wait for the 4G network to spread evenly first please. right?

In addition to the speed of access, the most noticeable in the development of this cellular network is the price of Internet packages. In the era of GPRS, the cheapest internet was 1 rupee per kilobyte, and now we can buy packages of tens of gigabytes at low prices. Now we usually buy data packages cell phone Up to 1 GB to allocate a week, in the age of GPRS we can call the rich. As you can see, 1 megabyte equals 1,000 kilobytes, and 1 gigabyte equals 1,000 megabytes. This means that 1 gigabyte equals 1 million kilobytes. This means that in the era of GPRS, we have to spend up to 1 million IDR to buy 1GB internet package, comrades!
