What is 5G Internet | 5G Internet Architecture, 5G Speed
This page describes 5G internet basics. It explains 5G internet architecture and mentions 5G internet speed and coverage range.
As we know Internet is a network of computers connected using wired and wireless connections. Dial up and broadband connections fall under wired internet category where as wifi, Lifi, 2G, 3G, 4G and 5G fall under wireless internet category. Internet has been used for variety of applications such as browsing, emails, surfing websites, mobile apps etc.
Like other internet types, user of 5G internet needs 5G compliant mobile phone and 5G service from 5G network operator with appropriate pre-paid or post-paid plan. 5G network is designed to support both cellular and Internet of things based applications. 5G will be used in various industries e.g. automotive, utilities, public safety, health care, finance, media, manufacturing etc. It supports wide use cases which include eMBB, mMTC, URLLC etc.
5G follows same 3GPP specification road map as followed by 4G LTE, LTE-advanced and LTE-advanced Pro. The technology as per this specifications is known as 5G NR (New radio).
5G Internet Architecture
The figure-1 depicts typical 5G NR network architecture. As shown it consists of 5G phone, 5G RAN and 5G core network infrastructure. 5G phones are of two main types viz. standalone and non-standalone. Standalone works independent of legacy wireless network such as 3G, 4G (LTE) etc. Standalone 5G mobile unit takes care of both control/data signaling using 5G network. Non-standalone unit does control signaling using legacy system (LTE) and data signaling using 5G network.
Following are the use cases of 5G internet.
• eMBB (Extreme throughput, Enhanced Spectral efficiency, Extended coverage)
• mMTC (High connection density, Energy efficiency, Low complexity, Extended coverage)
• URLLC (Low Latency, Ultra Reliability, Location Precision)
5G network incorporates following features in order to support above mentioned use cases.
➨Scalable OFDM (To support various coverage regions (outdoor, indoor, small cell, macro cell) in different frequency bands viz. less than 3GHz, greater than 3 GHz, 5GHz and 28 GHz (mmwave).
➨Multi-user Massive MIMO (to achieve spectral efficiency improvements and desired throughput at cell edges).
➨Advanced LDPC channel coding along with IR HARQ type
➨Self contained TDD subframe
➨Low latency slot structure design
➨Advanced modulation schemes e.g. OFDM, FBMC, UFMC and GFDM
What is 5G internet speed
The goal of the 5G internet is to provide speed of about 20 Gbps in the downlink (from eNB to mobile) and
10 Gbps in the uplink (from mobile to eNB) as claimed by most of the network operator.
Though the cell tower range of 5G is less than as supported by 4G LTE. It penetrates in the
inaccessible areas with the help of different types of 5G small cells viz. femto cell, pico cell, micro cell,
metro cell etc. These small cells cover range of up to 250 meters.
Small cell functions as repeater of 5G signals relayed by 5G eNB (i.e. 5G base station) to provide better
signal strength for the 5G mobile phone users.
