The Rise of “5G”

5G is the 5th generation mobile network which is a new global wireless standard after 1G, 2G, 3G, and 4G networks. 5G enables a new kind of network that is designed to connect virtually everyone and everything including machines, objects, and devices. 5G wireless technology is meant to deliver higher multi-Gbps peak data speeds, increased availability, more reliability, massive network capacity, ultra-low latency, and a more uniform user experience to more users. Higher performance and improved efficiency empower new user experiences and connect new industries. 5G will do much more than significantly improve your network connection. It provides new opportunities, enabling us to deliver groundbreaking solutions that reach across society. It is expected to provide at least 20GBPS downlink and 10GBPS uplink, which will make the 5G network to be at least 40 times faster than the current 4G LTE.

Low-band 5G operates in frequencies below 2GHz. These are the oldest cellular and TV frequencies. They go great distances, but there aren’t very wide channels available, and many of those channels are being used for 4G. Low-band 5G channels are from 5MHz in width (for AT&T) up to 15MHz (for T-Mobile), so you can see they aren’t roomier than 4G.

Mid-band 5G is in the 2–10GHz range. That covers most current cellular and Wi-Fi frequencies, as well as frequencies slightly above those. These networks have a decent range from their towers, often about half a mile, so in most other countries, these are the workhorse networks carrying most 5G traffic. Most other countries have offered around 100MHz to each of their carriers for mid-band 5G.

High-band 5G, or millimeter-wave, is the really new stuff. So far, this is mostly airwaves in the 20–100GHz range. These airwaves haven’t been used for consumer applications before. They’re very short range; our tests have shown about 800-foot distances from towers. But there are vast amounts of unused spectrum up there, which means very fast speeds using up to 800MHz at a time.

Previous Generations of Mobile Networks

First-generation (1G)
The 1980s: 1G delivered analog voice.

Second generation (2G)
In the early 1990s: 2G introduced digital voice.

Third generation (3G)
In the early 2000s: 3G brought mobile data.

Fourth generation (4G LTE)
The 2010s: 4G LTE ushered in the era of mobile broadband.


What makes 5G different?

New 5G NR devices and networks being launched at a rapid rate significantly faster and more globally than LTE after its commercial deployment. As it has wireless R&D at Qualcomm Technologies which is more fulfilling than seeing our 5G vision. This will open doors for new services, network operations, and customer experience for telecom operators. 5G coverage in both sub-6 GHz and mmWave will continue to grow and it is available through auctions and dynamic spectrum sharing (DSS). With DSS, we will not only see even broader 5G coverage in lower bands but also the enablement of direct migration from today’s non-standalone (NSA) networks to standalone (SA) networks. 5G NR enhanced mobile broadband (eMBB) as well as fixed wireless access so that it will a helpful for the people.


Both AT&T and Verizon are running forms of 5G that light up a ‘5G’ icon on your brand-new smartphone but feel and work exactly like 4G. 5G gives communication service providers the ability to serve a multitude of use-cases and use-places with lightning-fast connectivity. From smartphones to smart factories, 5G is the open innovation platform that enables society to leap towards a smarter, safer, and sustainable future. 5G is meant to seamlessly connect a massive number of embedded sensors in virtually everything through the ability to scale down in data rates, power, and mobility providing extremely lean and low-cost connectivity solutions. 5G brings three new aspects to the table:

  • Bigger channels
  • Lower latency
  • The ability to connect a lot more devices much faster

5G is driving global growth:

  • $13.1 Trillion of global economic output
  • $22.8 Million new jobs created
  • $265B global 5G CAPEX and R&D annually over the next 15 years

let’s imagine how it will help in various places:

1. Smart Societies

  • More connected vehicles sharing data to prevent road collisions and also faster deployment of emergency services to accidents
  • Drones becoming a key tool to accelerate and support emergency response
  • Remote expertise with specialists smoothly consulting/diagnosing patients elsewhere

2. Modifying Industries

  • Production lines autonomously reacting to supply and demand
  • Digital replicas that can warn about real machinery faults ahead of time
  • Increased use of IoT in agriculture to efficiently grow crops

3. Upgrading LifeStyle

  • Stable and reliable connectivity in crowded spaces
  • Immersive virtual meetings to boost remote team productivity
  • Delivering sensory experiences like touch through devices

Although, these new functionalities and new services necessitate a new way of deploying advanced mobile services as well as new approaches in making 5G technologies work together in industrial settings by machine-to-machine communications, Internet of Things (IoT), or with connected vehicles. With these ambitious goals, 5G networks face considerable challenges.
