Why is 5G really important?

The fifth generation (5G) of wireless technology. But users will know that this is one of the fastest and most robust technologies the world has ever seen. 5G is an opportunity to create an agile network specially designed to meet the different needs of citizens and the economy.

5G wireless technology is intended to deliver higher multi-Gbps peak data speeds, ultra-low latency, more reliability, massive network capacity, increased availability and a more uniform user experience for more people. users. 5G for consumers not only means faster mobile internet, but primarily internet connectivity in many more objects than you see today.

Bhutan Telecom Limited and Tashi Infocomm Limited are currently conducting 5G trials in the country to study its performance taking into account factors such as geographic landscape, population density and vegetation.

Types of 5G implementation architecture

There are two types of 5G architecture, namely StandAlone (SA) and Non-StandAlone (NSA). NSA is a 5G service that is not “stand-alone”, but is built on an existing 4G network and anchors the control signaling of 5G radio networks to the 4G core. SA, on the other hand, allows the completely independent operation of a 5G service without any interaction with an existing 4G core. The SA scheme connects the 5G radio directly to the 5G core network and the control signaling is not dependent on the 4G network at all.

The NSA will be easier to implement as 4G networks are already available in the country. Additionally, Bhutan would implement 5G primarily for eMBB (Enhanced Mobile Broadband) which would provide massive download throughput. This architecture would provide high-speed connectivity to consumers with 5G-enabled devices and help network operators maximize their existing LTE infrastructure while providing businesses and users with faster and more reliable communications.

Radio spectrum ranges

There are three types of 5G spectrum bands. 5G low band (coverage) which is about 20% faster than 4G LTE and has a frequency band below 1 GHz. Midband 5G is spectrum in the 1 GHz – 6 GHz range and it is considered ideal for 5G because it can carry a lot of data while traveling long distances (coverage with capacity). mmWave high-band 5G offers super fast speed over a short distance and has a frequency band above 24 GHz.

The development of 5G globally is accelerating, with this trend the Bhutan Authority is supporting 5G tracks in the country by making the following spectra available for 5G tracks in Bhutan.

Frequencies ranging from 3.4 GHz to 3.6 GHz have been allocated to Bhutan Telecom Limited and Tashi Infocomm Limited for 5G testing.

Why 5G?

Since 4G wireless network services were introduced, people have been able to experience broadband services with mobile devices. Despite these advanced 4G wireless network technologies, it is difficult to provide mobile services which require high speed, fast response, high reliability and energy efficiency. Therefore, in the age of 5G, it has created a network to provide instant cloud services, tactile internet, enhanced internet of things (IOT) and communications by ensuring the quality of experience for mobile users. It is an opportunity for industry, society and individuals to advance their digital ambitions, 5G being a catalyst for innovation.

By deploying 5G in Bhutan. Users will benefit from higher speeds of up to 20 Gbps in transmissions and ten times lower latency than 4G providing greater remote execution capacity. With 5G, the number of devices that can be connected to the network will increase dramatically until reaching the scale of millionaire per square kilometer and the possibility of implementing virtual networks (network slicing) to provide connectivity across the country. 4G can support around 4,000 devices per square kilometer, while 5G will support around one million devices. People can enjoy seamless live streaming connectivity with 5G hotspots like Samuh. Smart apps can be improved.

5G offers a higher speed than 4G where the 4G base station supports around 150 subscribers with a maximum data rate of 1 Gbps downlink and 500 Mbps uplink, and suppose the 5G base station supports Loads the same number of subscribers with a maximum data rate of 20 Gbps downlink and 10 Gbps uplink. However, 4G has practically reached the speed of 6.6 Mbps downlink and 3.3 Mbps uplink, while 5G could provide 133 Mbps downlink and 66 Mbps uplink. Therefore, it is always better to upgrade for better technologies than to hang on to older technologies like 3G and 4G.

With a minimum downlink speed of 133 Mbps, it will facilitate efficient and cost-effective transport networks by replacing fiber-optic connectivity requirements in homes and businesses. This will provide an opportunity to revisit the current per Mb to Per Mbps billing pricing structure, where telecom operators can consider selling dedicated internet speed with no data cap, especially for fixed devices.

As mobile network users increase, congestion occurs and degrades quality in terms of latency and throughput. 5G networks will ease the decongestion of 4G networks with more 4G users migrating to 5G.

In the future, 5G will allow machines to communicate without human intervention, such as smart parking or holographic conference calls we call the Internet of Things (IoT), capable of handling an almost endless range of services. Since 5G has a very negligible delay capacity between sending and receiving communications (latency), it will provide better access to medical treatments, reliably connecting patients to physicians around the world, including surgeries. in line.

Supported user device (IOS and Android)

Currently, the following list of mobile devices on the market would support 5G network considering the hardware that supports 5G radio spectrum bands: iPhone 12 (Mini, Pro, Pro Max), iPhone 13 (Mini, Pro, Pro Max), Samsung Galaxy S10 5G, Samsung Galaxy Note 20 Ultra, Samsung Galaxy S21 series, Samsung Galaxy S21 Ultra, Samsung Galaxy Fold, Huawei Mate X, OnePlus 5G phone, Xiaomi Mi 11 series, Xiaomi Mi Mix 3, LG V50 ThinQ and OnePlus 9 Pro.

With the release of patches that support Bhutan’s spectrum and 5G network, all mobile devices that support 5G can be used in Bhutan as two telecom operators are currently working with the

handset manufacturer for fixes. However, with the development of the entire 5G ecosystem, the prices of handsets are expected to drop and become affordable.
