What is 5G ? The emergence of 5G technology represent a significant impact on the course of human history. 5G stands for 5th generation of mobile network technology. It is the latest iteration of wireless technology that succeeds 4G.
It is going to revolutionize the way we communicate, work and live. Unlike its predecessors, 5G is not just an incremental improvement but a transformative leap in terms of speed, capacity and latency.
It relies on three fundamental pillars to deliver these advancements:
Higher Frequency: 5G operates across a broader spectrum, including higher frequency bands such as millimetre waves (mmWave). These high-frequency band allows for much faster data transmission rates.
Massive MIMO (Multiple input, Multiple output): 5G network utilize advanced antenna technology to support multiple simultaneous connections. Massive MIMO enhances network capacity and efficiency.
Low Latency: 5G network offers significantly reduced latency, the time it takes for data to travel form the sender to the receiver. This low latency is crucial for applications requiring real time responsiveness, like remote surgery and autonomous vehicles.
Who created 5G ?
5G is not owned by any single entity or a country. It has been developed by 3GPP (3rd Generation Partnership Project), which is an umbrella term for a few standards organizations which develop protocols for mobile telecommunications. Its best-known works are the development and maintenance of:
GSM and related 2G and 2.5G standards, including GPRS and EDGE
UMTS and related 3G standards, including HSPA and HSPA+
LTE and related 4g standards, including LTE Advanced and LTE Advanced Pro

How 5G technology works?
Similar to its predecessors, 5G technology relies on cellular infrastructure that transmits data via radio waves. These cell sites establish connections with networks through either wireless or wired means. The innovation behind 5G lies in its alteration of data encoding, which substantially augments the available airwaves for carriers.
Orthogonal Frequency Division Multiplexing (OFDM): One pivotal component of 5G technology is Orthogonal Frequency Division Multiplexing (OFDM). OFDM serves as a modulation format that encodes high-frequency airwaves not compatible with 4G, delivering reduced latency and enhanced flexibility compared to LTE networks.
Deployment of Smaller Towers: Additionally, 5G technology deploys smaller transmitters situated on structures like buildings and other infrastructure. Unlike 4G and earlier cellular technologies that relied on standalone mobile towers, 5G leverages these small cell sites to efficiently support numerous devices at superior speeds.
Network Slicing: 5G technology introduces the concept of network slicing, enabling mobile network operators to create multiple independent virtual networks utilizing the same underlying infrastructure. Each network slice can be tailored to cater to distinct services and business requirements, such as streaming services or enterprise functions. By assembling a set of 5G network functionalities for each specific use case or business model, diverse needs across various industries can be accommodated. This segregation of services results in users enjoying a more dependable experience and increased device efficiency.
What makes 5G special?
While 5G operates within the same radio frequency spectrum as previous generations, it exhibits several notable distinctions when compared to 4G, 4G LTE, and 3G. These disparities encompass:
Ultra-fast Speed: 5G networks can achieve staggering speeds of up to 10 gigabits per second, a tenfold increase over the velocity of 4G networks. Consequently, tasks that were once time-consuming, such as downloading a movie or backing up a database, now take only a fraction of the time they previously required.
Reduced Latency: The primary driver behind this speed boost is the remarkably low latency of 5G. Latency refers to the delay between the transmission and reception of data. While 4G networks typically offered latency levels of approximately 200 milliseconds, 5G has slashed this delay to just one millisecond.
Expanded Bandwidth: 5G technology is designed to operate across a wider spectrum of bandwidths, encompassing low band, mid band, and high band frequencies. This expansion leverages radio spectrum resources, extending from the sub-3 GHz range used by 4G to frequencies of 100 GHz and beyond. 5G's ability to function in both lower bands and mmWave frequencies significantly augments its capacity, enabling multi-gigabit per second throughput and minimal latency. Consequently, more devices can be simultaneously connected, facilitating efficient data transmission.
