Telkomsel officially launched 5G Internet services on Thursday 27 May. This is a historic day for internet technology in the country.
“Today is a very important and historic day because, with the rollout of 5G in Indonesia, a new chapter opens and Telkomsel is the first mobile operator to offer 5G services,” Telkomsel CEO Setyanto Hantoro said during the inauguration of 5G services in Jakarta.
Telkomsel and Smartfren have previously won additional 2.3 GHz frequencies. Telkomsel is known to have received block A and C allocations after being one of the winners of a 2.3 GHz radio frequency auction.
5G services have been tested in Indonesia since 2018. They took place in the industrial area of Batam island.
The Certificate of Acceptance for Telkomsel was issued by the General Directorate of Postal and Information Technology Operations on May 21, 2021, and the Acceptance Test (ULO) was carried out on May 19-20.
Telkomsel uses the radio frequency spectrum in the 2.3 GHz frequency band to provide 5G services.
Initially, six districts were prepared for 5G in the Jakarta-Bogor-Depok-Tangerang-Bekasi (Jabodetabek) area, namely Kelapa Gading, Pondok Indah, Pantai Indah Kapuk, Bumi Serpong Damai, Widya Chandra and Alam Sutera. These are the elite areas in Jakarta.
Telkomsel further plans to launch 5G services in Batam, Medan, Solo, Bandung, Surabaya, Makassar, Denpasar and Balikpapan.
5G is the fifth generation of GSM wireless networks in the world after 4G, 3G, 2G, and 1G. This revolution in telecommunications networks occurs approximately every 10 years.
Each mobile network technology update brings with it several new features. For example, when 1G was introduced, it could only be used for phone calls in the 1980s.
Then, in the 1990s, the 2G standard was introduced so that users could not only make calls but also send short messages (SMS).
3G networks emerged around the 2000s and revolutionized the Internet with the introduction of Internet services that could be accessed from mobile phones. However, the speed was only 8 Megabits per second. This is very slow compared to today’s internet speed.
4G came along in 2009, this fourth-generation network increased download speeds 10 times over 3G.
There are three main differences between 4G and 5G, namely speed, capacity, and latency
Speed is one of the most anticipated elements of the next-generation network. The 5G network is expected to be nearly 100 times faster than 4G. At this speed, you can download a two-hour movie in less than 10 seconds, while on 4G the task takes about seven minutes.
Everyone experiences unpleasant moments when they are in a relatively small area with a group of people, such as at a concert, at a sports stadium, or an airport during the holiday season. Too many devices trying to use the network in one location can cause congestion.
The network infrastructure cannot handle a large number of devices, resulting in lower data rates and increased download latency. 5G is expected to address this issue. The next-generation network is expected to have a much higher capacity than 4G.
There is a small but significant difference between speed and latency. Speed is the time it takes for your phone to load the content of a web page.
Meanwhile, the delay is the time between sending an SMS to a friend’s mobile phone and the moment the mobile is registered when the phone receives a new message.
In 4G, the latency is quite low, but 5G will make it almost zero. This will be important for other technologies, such as driverless cars, that need to send signals about their environment over the Internet to computers in the cloud.
