Generations of Mobile networks
1G (First Generation):
- Timeline: 1980s
- Technology: Analog
- Peak Data Rate:4 Kbps
- Key Features: Basic voice services
- Latency: High
2G (Second Generation):
- Nature: It is a non-profit organization that was established on September 18, 1998.
- Core Function: It is primarily responsible for coordinating the internet’s Domain Name System (DNS), IP address allocation, and protocol parameter assignment. It ensures that computers across the world can find each other.
- IANA Operations: ICANN operates the Internet Assigned Numbers Authority (IANA) functions, which include managing the DNS root zone.
- Historic Transition: In 2016, ICANN underwent a major transition that officially ended the U.S. government’s direct oversight of key IANA functions, shifting control to the global internet community to enhance accountability.
2.5G (General Packet Radio Service) (GPRS) and 2.75G Enhanced Data rates for GSM Evolution (EDGE):
- Timeline: Late 1990s (GPRS), Early 2000s (EDGE)
- Peak Data Rate: GPRS – Up to 171 Kbps, EDGE – Up to 1 Mbps
- Key Features: Introduction of packet-switched data
- Latency: Medium to Low
3G (Third Generation):
- Timeline: Early 2000s
- Technology: UMTS (Universal Mobile Telecommunications System)
- Peak Data Rate: Up to 14 Mbps
- Key Features: High-speed data transmission, video calling
- Latency: Medium to Low
3.5G High-Speed Packet Access (HSPA) and 3.9G (HSPA+):
- Timeline: Mid-2000s (HSPA), Late 2000s (HSPA+)
- Peak Data Rate: HSPA – Up to 42 Mbps, HSPA+ – Up to 168 Mbps
- Key Features: Improved data rates, network efficiency
- Latency: Medium to Very Low
4G (Fourth Generation - LTE):
- Timeline: 2009 onwards
- Technology: LTE (Long-Term Evolution)
- Peak Data Rate: Up to 1 Gbps
- Key Features: High-speed data, VoLTE, optimized IP-based communication
- Latency: Low
4.5G (LTE Advanced) and 4.9G (LTE Advanced Pro):
- Timeline: Late 2010s (LTE Advanced), Ongoing (LTE Advanced Pro)
- Peak Data Rate: LTE Advanced – Up to 3 Gbps
- Key Features: Enhanced LTE features, better IoT support
- Latency: Very Low
VoLTE (Voice over LTE)
Before 4G, voice calls and internet data used separate network pathways.
- Mechanism: VoLTE is a standard that transmits voice calls directly over the 4G LTE data network rather than falling back to 2G or 3G voice networks.
- Benefits: It provides High-Definition (HD) voice clarity, much faster call setup times, and allows users to browse high-speed data while simultaneously being on a voice call.
5G (Fifth Generation)
Launched from 2020 onwards, 5G uses NR (New Radio) technology. It is not just for mobile phones; it is designed to connect machines, objects, and devices globally.
- Speed and Performance: It offers ultra-fast peak data rates up to 20 Gbps and extremely low latency (near real-time response).
- Key Features: It supports massive device connectivity (crucial for the Internet of Things) and introduces network slicing (creating multiple virtual networks on a single physical 5G infrastructure for different uses).
- Deployment Modes:
- NSA (Non-Stand-Alone): The initial 5G rollout that relies on existing 4G infrastructure for control functions, allowing faster deployment but limited 5G features.
- SA (Stand-Alone): A completely independent implementation using its own dedicated 5G core network, unlocking the full capabilities of 5G.
100 5G Labs
- Prime Minister Narendra Modi announced the establishment of 100 5G labs across India that will serve as testing and breeding grounds for local innovators, students, and startups to develop a new range of applications in various sectors. This initiative unveiled at the India Mobile Congress 2023 will have a transformative impact on India’s technological landscape.
- It is believed that these 100 5G labs will play a crucial role in upskilling local innovators, students, and startups, fostering the development of a new generation of applications tailored to the country’s needs.
6G Technology
