What is 5G

What is 5G? Explained and Simplified..

“What is 5G, why so much uproar around? Is it just about the speed which is 100 times faster than 4G? 4G was also much faster than 3G but 4G was never that much hyped. What will change with 5G? Is it more software centric? People talking about virtualisation a lot with 5G, what exactly is the role? Seems like all the latest technologies are contributing to 5G or is it other way round? Oh my God, I need this simplified.”

Hey! Do you have all such questions in mind and may be many more as well. Relax! ICT Future is going to simplify this and make you understand the real thing.

Let’s start..

Yes, 5G is 100 times faster than 4G. It’s the 5th generation of cellular network. 5G offers ultra low latency, hence it creates opportunity for unlimited applications for each and every industry to be precise. It’s an excellent solution for Mission-critical communication. Services which were on our wish list in future like Telemedicine, Self-Driven Cars, Intelligent Transport and Traffic System, Smart Manufacturing, Mobile Cloud Gaming, Augment Reality and Cashing are being a reality to be availed with 5G. Downloading a HD movie will be possible just in a few seconds. In nutshell, 5G network is designed to connect virtually everyone and everything including devices, objects and machines.

The Inventors of 5G

3rd Generation Partnership Project (3GPP) defines the specifications for 5G as well along with 3G UMTS and 4G LTE in the past. In case of 5G along with 3GPP other telecom equipment, device, component manufacturers and network operators are the members of the 5G initiative.

The 5G Advantage over 4G

  • Faster than 4G – Delivers up to 20 Gbps peak data rates and 100+ Mbps average data rates.
  • More capacity – It supports 100 times more traffic capacity.
  • Lower latency – It offers latency as low as 1ms.
  • More capabilities – Application intensive 
  • Better spectrum utilisation – Wide spectrum spread over 3 bands

5G Frequency Bands

5G spectrum is widely available in 3 bands.

Low Band: 600 MHz

Mid Band: 1-6 GHz

High Band: Millimetre Wave

Where 5G can be used?

Here are a few applications which can benefit individual users, society and industries. However there can be a many such more.

1. Enhanced User Experience : Mobile Broadband

  • VR (Virtual Reality), AR (Augmented Reality) and XR (Extended Reality)
  • Feature rich virtual meetings
  • Reliable connection and ultra high speed
  • High quality live streaming
  • Enhanced teaching and education experience

2. Benefitting Societies : Mission-critical communications

  • Connected vehicles with built-in intelligence to get instant support for break down
  • Connected sensors can warn us about natural disasters early
  • Rapid emergency response using drones
  • Smart electricity grids helping reduction in carbon footprint
  • Robotic surgery and telemedicine
  • Autonomous Vehicles (Self driven cars etc.)

3. Benefitting Industries – Massive IoT

  • Smart demand and supply driven production lines
  • Intensive manufacturing quality check and measures
  • Intelligent farming with massive sensor network
  • Asset tracking by loan, insurance and transport companies
  • Intelligent logistics- goods routing based upon real world conditions
  • Sensor network for Oil and gas companies to report leakage or fire to avoid disasters
