    5G speed | 5G vs 4G | How many countries have 5g networks? | New 5G phones

    5g speed & latency are the most significant features offering new enterprise revenue models and business opportunities. Cellular networks revolutionized from 3g to 4g LTE with the strong demand for mobile broadband. 4g speed paved the way for many social apps like YouTube, Facebook, and OTT streaming apps like Netflix, Hotstar, Prime, etc. Currently, there are more than 40 countries with tested & trialed 5g networks across the world.

    Difference between 4G and 5G network:

    5g technology is expected to be much faster than 4g, offering higher broadband speed (throughput), lower latency & much higher bandwidth.

    5G Speed

    Data speed is the most common differentiator between 4G & 5G.

    The 4G top speed can reach up to 100Mbps but its real-world speed is only up to 35Mbps. Now let’s look at the 5G speed:

    • Peak downlink 5g speed is 20 Gbps
    • Peak uplink 5g speed is 10 Gbps.

    However, the 5G average user experience data rate is ranging between 100 Mbps to a peak of 3 Gbps. overall, it ensures at least 50 Mbps everywhere.

    So, How long it takes to download a two hours movie?

    5G Latency

    Latency is a measure of time that a data packet takes to travel between two points. Key 5g services like remote surgery, mission-critical robots, self-driving cars, etc. are built on the 5g ultra-low and reliable services.

    4G networks latency is approx 50 milli seconds (ms) whereas,

    5G URLLC (ultra-reliable and low latency) latency is only 0.5 ms.

    And the eMBB (Enhanced broadband) latency is 4 ms

    5G Coverage

    4G has major issues with low coverage and very low connection density, because of the spectrum capacity.

    • Typically 4G antennas can support only 2000 devices per square kilometer.

    Even though 5G is in infancy, it can support nearly one million devices (phones, sensors, machines, etc.) per square kilometer.

    5G spectrum

    5G certainly has more spectrum capacity than 4G.

    4G spectrum was 600MHz to 2.5GHz which uses a narrow slice.

    5G spectrum has two bands:

    (i) sub-6GHz: It is suitable for broadband services around densely populated urban areas, catering to the need of consumers, businesses, and industries.

    (ii) mmW (millimeter wave): is capable to serve hotspots areas like stadiums, airports where the data rate demand is huge, up to 5Gbps.

    5G network countries:

    As per Q1 2021, commercial 5G networks are present in more than 60 countries worldwide wherein hundreds of telco operators have tested or trialed it so far. Out of them, China & the USA are the top two players followed by South Korea having the most cities with 5G networks.

    5G in China:

    • Covering around 350 cities, China has made the fastest 5G adoption. The top three CSPs in China – China Mobile, China Unicom, and China Telecom have already deployed 5G since 2019.
    • It’s the sub-6GHz spectrum band used in entire China, mmWave license will be added later by the Govt.
    • There’re 500K+ 5G base stations that have been installed in most of the major cities in China
    • Moreover, there’re 50 million subscribers using 5G, and around 100 million 5G mobile phones
    • The average 5G data cost is around 0.7 USD per 1Gb.

    5G in the USA:

    • Covering around 280 cities by major operators, the USA is in the second position. Verizon was the first to turn on 5G, sooner followed by AT&T, T-Mobile & Sprint.
    • Initially, it started with the mmW based deployments however, sub-6GHz was also been used afterward. So it’s a mix of mmW and sub-6HHz. Also to cover entire cities, C-band (low band< 6GHz) is coming soon in the USA.
    • It is mostly non-standalone (NSA) based deployments in the US, which means 5G is leveraging the existing 4G coverage to set up a connection.
    • More than 200 million customers are now covered by the 5G networks across the country.

    In Europe, 27 operators are using mostly sub-6GHz to deploy 5G networks. Leading 5G countries in Europe are the UK and Spain.

    Likewise in Asia, South Korea and Japan are expected to be covered by 5G in 2021. Here it’s mainly millimeter wave (mmW) driven deployment. Similarly, Middle East, Australia, and South Africa also not far behind, launched 5G in 2019.

    5G phones

    Change in every telecom generation means more RF (radio frequency) components, antennas to be integrated inside the mobile phone, and accordingly, it’ll be a more complex & costlier hardware design.

    5G device cost is approximately 2.5 times than a 4G device.

    Some examples of 5G enabled mobile phones are:

    • Samsung Galaxy S10 5G
    • Samsung Galaxy Note10+ 5G
    • Samsung Galaxy A90 5G
    • OnePlus 7 Pro 5G
    • Moto z3
    • Xiaomi Mi MIX 3 5G
    • Huawei Mate X
    • Huawei Mate 30 Pro 5G

    What is 5G | 5G networks | 5G technologies: AR, VR, IoT

    5th generation telecom standard (5G) has been buzzing in recent times to cater to nearly 2 billion mobile subscribers worldwide by 2025. But what is 5G? Unlike 4G, 5G is more than just a telecom generation, it is capable of having a network within a network. It serves many new applications like Machine to Machine (M2M) communication, Internet of Things (IoT) and enables new revenue growth opportunities for the communication service providers (CSPs).

    Let us look at the evolution of 5G:

    GenerationTechnologyFeature ServicesPeak Speed
    1G was about analog communicationCellular technology [AMPS]Only Voice14kbps
    2G was the era of Digital TechnologyGPRS, EDGEVoice, SMS, Email384Kbps
    3G was the era of Mobile InternetUMTS, CDMAVideo Calling, BoD, Web browsing2Mbps
    4G was the era of Mobile BroadbandLTEVoLTE, VoIP, High speed data, Video calling, IPTV, OTT Streaming100Mbps

    What is 5G?

    5G network is promised to transform businesses and society. Significantly, it enables faster connectivity and faster services and brings new opportunities, new revenue streams, and new business models with it.

    In short, with a higher capacity, 5G is expected to connect anything (mobiles, machines, sensors…) in the physical world to the Internet.

    Why 5G?

    4G has laid the mobile broadband platform for audio & video content over the Internet, Social networking, P2P file sharing, Streaming apps. Examples are different OTT platforms like Netflix, Amazon Prime, Hotstar, and so on. As the mobile data traffic (Video streaming) went up with the increasing mobile subscriptions, simply 4G cannot satisfy this enormous demand. Here are some interesting statistics:

    1. Mobile broadband traffic is expected to grow ~ 30% YoY until 2024
    2. Advanced services such as Augmented Reality (AR), Virtual Reality (VR), UHD, 360Deg Video are also in demand, expected to transform the digital world
    3. In addition, recent analysis shows OTT (Netflix/ Prime) traffic went up by ~ 55%
    4. Moreover, the global Internet of Things market is expected to reach ~ USD 724.2 Billion by 2023

    5G Services:

    5G use cases

    1. 5G Enhanced mobile broadband (eMBB):

    5G enhances limited 4G LTE capabilities to provide a greater capacity mobile broadband with higher bandwidth and higher throughput [1 Gbps user exp., at least 50 Mbps everywhere]. The ultimate goal is to deliver seamless coverage with high connection density to the end-users.

    1.1 Smart Home/ Office

    • Mobile broadband handles heavy data traffic of hundreds of users in an office environment.
    • Alexa-enabled smart home solutions are capable of controlling the lights, TV, music system, AC, Geyser, Air purifier, Vacumn cleaner, and other connected devices.

    1.2 Virtual Reality (VR)

    • High resolution streaming display (4k/8k video) for watching virtual reality contents
    5G Virtual reality gaming
    • Virtual Reality is not just about gaming, it is revolutionizing other industries like Sports, Education, Military, Medicine, etc. Examples are ClassVR (Educational VR App), VR360 (science and industrial use), Facebook Horizon (online gaming), VR-enabled movies, etc.

    1.3 Augmented Reality (AR)

    Unlike VR, augmented reality superimposes an image on top of a video or camera to feel like a real physical thing with sound and other technologies. Some examples are:

    5G Augmented reality
    • Google Map AR application shows digital navigation by recognizing the building names, street view & visual positioning.
    • Google Lens reads the object & gives all essential details
    • Snapchat AR filter transforms the objects & their characters by introducing a 3D effect

    2. 5G Massive machine type communication (MMTC):

    Millions of IoT sensors deployed very densely to capture, track small signals and send them back to the centralized server. The IoT signals are:

    • Occasional data communication (Delay tolerant)
    • Low data rate
    • Low data volume
    • Long battery life
    • A large number of devices / deep coverage

    2.1 NB-IoT (narrow band), Mass sensors

    Agri IoT
    • Firstly, agricultural mass sensors to track weather parameters
    • Secondly, connected wearables that capture health conditions such as Apple Watch, Fitbit, etc.
    • Finally, industrial IoT applications use mass sensors (temp sensor, pressure sensor, image sensor, motion detector sensor, and many more..)

    2.2 Smart City, Smart Meters

    • For example, Smart Parking, Smart street lighting, Waste management, Smart connected grid, and many more.
    • In other words, smart indoor electric appliances, connected utility meters, home security systems, smart locks are connected meters.

    3. 5G Ultra-reliable and low latency communications (URLLC):

    5G new radio communication (5G NR) addresses LTE latency issues and it is capable of much faster & smoother communication with a minimal delay (or latency) and high reliability.

    Above all URLLC is the most powerful and promising 5G capability, it is also termed as critical machine type communication.

    Ultra-high reliability: It means the network cannot have downtime even for few seconds.

    Ultra-low latency With URLLC latency of 0.5 milliseconds, it ensures almost zero time lag from the controlling point.


    3.1 Mission Critical Applications (Remote surgery, Robots)

    A remote surgical robot is able to conduct surgery from a distant controlling point where network reliability and very low latency are of utmost importance. Therefore, 5G secures zero time tag in the whole surgery process otherwise it might cause very severe consequences.

    3.2 Self Driving Car

    • Similarly, using URLLC service, the vehicles connect to each other, to other network services, to other cyclists, and guarantee no accident takes place.
    • Whereas the car infotainment system like music, gaming are other services deployed on the eMBB capability not on URLLC.
    Connected cars

    4. 5G Fixed wireless access (FWA):

    Finally & most importantly, CSPs have the unused spectrum band which they can monetize for the suburban areas by providing fixed wireless access with a minimum speed of 50 Mbps. The FWA revenue model works on top of the eMBB revenue model.

    4.1 Hotspots/ Public Transportation

    For instance, using consumer premise equipment (CPE) to boost indoor and outdoor coverage by the ethernet hotspot can be an FWA case.

    4.2 Broadband everywhere:

    Similarly, FWA also provides consistent broadband coverage at 50Mbps at rural cellular sites using the unused allocated spectrum.
