Mobile networks have seen a major transformation since the launch of the first-generation mobile services, which were capable of transmitting only voice calls. The current generation of mobile networks (fourth-generation, or 4G) is adept in handling higher data speeds required for multimedia streaming, besides providing basic network operations like voice calls, messages, and web browsing. However, with the changing connectivity needs, rising mobile data traffic and a new category of connected-ecosystem products, there is a need for yet newer generation of mobile networks that can provide even higher data speeds at low latency and enhanced throughput to handle more simultaneous connections without causing disruptions. And, this is exactly what 5G telephony is all about.
As the name suggests, 5G is the fifth-generation cellular network technology. It is designed to improve network connections by addressing the legacy issues of speed, latency, and utility, which the earlier generations and the current generation of mobile networks could not address. 5G is promised to deliver data speed at a rate 100 times faster than 4G networks. Importantly, it is designed to transmit data almost instantly with a network latency of less than 10ms. It will also have an enhanced throughput to handle more simultaneous connections at a time than current-generation networks.
Reliance Jio is another leading player in the field of 5G testing technology. The company has successfully conducted trials of connected drones on its indigenous 5G network.
According to Mukesh Ambani, Chairman and Managing Director, Reliance Industries Limited (RIL), India must complete the migration from 2G to 4G to 5G at the earliest and the rollout of 5G should be India's national priority.
The government today named 13 cities that are likely to see the launch of 5G services in the country, next year. These cities include - Gurugram, Bengaluru, Kolkata, Mumbai, Chandigarh, Delhi, Jamnagar, Ahmadabad, Chennai, Hyderabad, Lucknow, Pune, and Gandhi Nagar.
In telecommunications, 5G is the fifth generation technology standard for broadband cellular networks, which cellular phone companies began deploying worldwide in 2019, and is the planned successor to the 4G networks which provide connectivity to most current cellphones. 5G networks are predicted to have more than 1.7 billion subscribers worldwide by 2025.
The previous generations of mobile networks are 1G, 2G, 3G, and 4G.
First-generation - 1G
The 1980s: 1G delivered analog voice.
Second generation - 2G
In the early 1990s: 2G introduced digital voice (e.g. CDMA- Code Division Multiple Access).
Third generation - 3G
In the early 2000s: 3G brought mobile data (e.g. CDMA2000).
Fourth-generation - 4G LTE
The 2010s: 4G LTE ushered in the era of mobile broadband.
1G, 2G, 3G, and 4G all led to 5G, which is designed to provide more connectivity than was ever available before.
5G is a unified, more capable air interface. It has been designed with an extended capacity to enable next-generation user experiences, empower new deployment models, and deliver new services.
With high speeds, superior reliability, and negligible latency, 5G will expand the mobile ecosystem into new realms. 5G will impact every industry, making safer transportation, remote healthcare, precision agriculture, digitized logistics — and more — a reality.
5G Vs. 4G
A new generation of mobile network technology stands ready to go further than its predecessors could have dreamed.
What does 5G mean? Simply put, 5G is short for “5th generation.” You may also see the standard called 5G-NR (the NR stands for “new radio”). If the earliest mobile network—analog voice calls, no SMS, no mobile data or browsing—was the first generation, 5G is its great-great-grandchild.
When today’s 4G long-term evolution (LTE) mobile networks started rolling out nearly a decade ago, consumers welcomed a new era of rich media mobile browsing. Representing both an evolution of the 4G standard and a revolution in radio technology, 5G technology promises to transform the 2020s into a time of unprecedented connectivity and technological advancement. With higher capacity and speed, plus ultralow latency, 5G will power innovation that would have been impossible under the 4G LTE standard.
5G Use Cases :
The transformative power of 5G will touch nearly every industry. Compelling 5G use cases have already been identified in the healthcare, agriculture, retail, transportation, logistics, and manufacturing industries, among others.
Media and Entertainment
The availability of broadband made it possible to move movies, TV, and gaming to the cloud. Now, 5G promises to bring even richer media experiences to any screen, anywhere. End users will be able to enjoy smooth video streaming in 4K, immersive virtual reality (VR) experiences, and highly responsive gameplay on devices connected to a 5G network, leading to greater revenue opportunities for content creators, cloud service providers, and communications service providers.
Manufacturing
The convergence of 5G with AI and the intelligent edge will revolutionize the factory floor in ways not seen since Henry Ford unveiled the first assembly line. Supply chain, inventory management, and quality assurance processes, augmented by IoT and edge computing, will increase automation levels and reduce unit costs.
Retail
Modern brick-and-mortar stores face an uphill battle to keep customers due to the onslaught of online retail. With 5G, retailers of the future will power new omnichannel customer experiences. One way? Taking the cash register out of retail transactions. By using AI-enabled cameras with low latency, retailers will be able to create an automatic checkout experience that’s as simple as walking out of the store with your full cart.
Healthcare
For doctors and patients, 5G represents a new frontier of care. Imagine a wearable insulin pump that uses AI to give individualized suggestions about diabetes management to the patient’s endocrinologist or a smart implanted defibrillator that automatically and safely restarts a stopped heart—and instantly notifies the patient’s cardiologist with information about the incident.
