| Abstract | Wireless technology has come a long way in the past few decades by revolutionizing the way in which humans and systems communicate. 1G to 5G: The Quantum leap in Data speed, latency, capacity and connectivity. But the demand for ever more complex and powerful networks is ever-accelerating, and research is already paving the way for next-generation tech - 6G and beyond. # Wireless communication: 5G, IoT, Challenges & advancements 1G: Wireless Communication Technology Emergence - Analog Voice Transmission This technology was the cornerstone of mobile telephony but it was insecure, had a low capacity, and capacity was affected a lot by interference. This is where it hits 2G and goes from analogue to digital, bringing SMS, MMS and basic data transfer in the 90s. 3G, which arrived in the early 2000s, brought even faster data and with it the mobile internet, video calling and streaming services. This got even better with 4G LTE, which gave way to way higher capacity and capability with far lower lag and better reliability than anything we'd ever seen before, enabling HD video streaming, cloud computing, and IoT applications to become possible. 5G overview 5G is a visionary transformation of wireless communication. With data speeds reaching 10 gigabits per second and ultra-low latency, 5G enables one million connected devices per square kilometer, paving the way for revolutionary applications in areas like autonomous vehicles, smart cities, industrial automation and remote surgeries. The fundamental technologies that power 5G are millimeter wave spectrum, massive MIMO, beamforming, and network slicing. This allows for superefficient, ultrafast, and low-latency communications that span multiple industries. Despite the revolutionary potential of 5G, it has downsides, such as limited availability in rural areas, higher construction costs and security concerns. Now, to build up from the 5G deficiencies and maintain a pathway to satisfy the grandly gluttonous appetite for better and better connectivity, researchers are already laying plans for 6G and beyond. Expected to be commercialised in 2030, 6G is expected to enable terahertz communication with a ground-breaking speed of over 100 Gbps and latency below microseconds. It will tie together the AI-enabled network optimization, quantum communication, and extended reality with a specific focus on human-machine interaction. © 2025 IEEE. |
