still Remember those cell phones that were the size of a brick and could only make voice calls? Did it occur to you back then that cell phones would evolve into smart phone The ones we use today, small size, high quality color screens very accurate (HD), and are the various functions and services integrated in it? Have you ever thought about what kind of mobile phone will develop in the future?

1G to 5G

Each generation of the wireless (wireless) communication standard – abbreviated “G” for “generation” – is making progress in increasing capacity and speed. The first generation of cellular network, i.e. 1G, was launched by Nippon Telegraph and Telephone (NTT) in Tokyo, Japan, in 1979.

1G networks that still use analog technology have a number of weaknesses, namely large sizes, limited coverage, poor voice quality, and incompatibility between systems and operators. The 1G security system is also very bad because the calls are not encrypted.

Although it has many weaknesses, the 1G network, which was the beginning of the wireless communications revolution, still receives great attention. This can be seen by the large number of subscribers to the network.

At the time, having a cordless cell phone that you could carry everywhere was the trend. The reason is that the telecommunication devices known at that time were landline telephones that used cables.

12 years later, the 2G network was launched in Finland, in 1991 to be exact, by applying the standard Global System for Mobile Communications (GSM). 2G networks apply digital technology that allows a number of messages to be sent, such as text messages or emails SMS Service (SMS), picture messages, multimedia messages or Multimedia Messaging Service (MMS), can be sent via mobile phone.

In addition, the second generation is also distinguished by increased capacity and speed. In this generation, calls can be encrypted so that the level of security goes up.

The next generation, 3G, was launched by NTT DoCoMo in 2001. In this generation, the network protocols used by vendors have been standardized so that users can access data from anywhere in the world.

The ability to transfer data on the 3G network has increased four times faster than in the second generation. The 3G era is also marked by the emergence of new services, such as video conferencingvideo streamingAnd Voice transmission over the Internet (VoIP).

Furthermore, the 4G network was first used in Stockholm, Sweden, and Oslo, Norway, in 2009 through the implementation of the standard long term development (LTE). This network provides Internet speeds of up to 1 gigabyte per second, providing services gamesHD video and video conferencing High quality (HQ) can be accessed.

The latest network, 5G, was first rolled out by South Korea on Saturday (1/12/2018). This network is expected to be ten times faster than 4G. Created thanks to Bandwidth More and less response time. In addition, 5G networks also provide a high level of security and low power consumption. 5G network is expected to support needs The Internet of things (The Internet of things).

5G: era The Internet of things

The Internet of Things is defined as a device capable of transmitting or transmitting data over a network without using a computer and human devices. The Internet of Things will be a great digital revolution and will be able to connect billions of devices. Users from all over the world can share data with each other.

The number of connected devices is expected to rise to 3.2 billion by 2023. In the future, mobile phones will not just be mobile phones, but the Internet of Things in your pocket. Cell phones can connect to a wide variety of existing devices, and are no longer just limited to communication between phones.

The success of the Internet of Things depends on the speed of the Internet. 4G cannot support IoT needs because the latency is too high to use At present. Based on this need, 5G networks have been developed over the years.

The 5G network is 10 times faster than the 4G network. Increased speed will enable IoT devices to connect and share data smoothly At present. In addition to the increased speed, the 5G network will operate more reliably to create a more stable connection.

Reliable and stable network conditions are essential for the Internet of Things. Mainly, for connected security devices such as locks, security cameras and other monitoring systems that operate simultaneously At present.

5G: Connect to metaverse

metaverse It is a new concept in the digital world that combines elements of reality technology, such as Virtual Reality (VR), augmented reality (Arabic) , extended realityAnd Mixed reality (MR), by At present. Users from all over the world can log in and communicate with each other metaverse only through smart phone.

In the metaverseEach person will be represented with an avatar complete with clothing, hair and skin color, and realistic accessories. The avatar is a default display for the user.

All graphics are displayed in real time At present Based on sensor data that visualizes 3D objects in the real world through motion and sound. This sensor is installed in several devices, namely Earphone VR and touch gloves.

Simply, metaverse It can be said that it is a virtual meeting place with other people. metaverse It can also be a way to work, study, play and socialize virtually and is expected to become a global trend, including in Indonesia.

To be able to offer an experience like the real world in metaverse-Requires support for a fast, reliable and secure internet connection. 5G network with features of high speed and low latency will support connection to metaverse.

Close

With various advantages as described, the 5G network really deserves to be called the universal connector. Wireless networks will definitely continue to grow towards 6G, 7G, etc.

In fact, since 2019, China has been searching for 6G networks. Aside from just numbers, network development will be accompanied by various capacity improvements that may not even be imagined at this time.

As a large country rich in human and natural resources, Indonesia should not only be a consumer, but also participate in the development of network technology. Thus, we can free ourselves from dependence on products from abroad.

For this reason, it is time for future generations of the nation to see this great challenge and opportunity immediately. The first step is to master the field of electrical engineering. Surely, we will be the masters of our country.
