Let's delve into the technical differences and advancements of these generations of mobile network technologies:

Time Period: 1980s
Technology: Analog cellular networks

Frequency Band: Primarily used the 800 MHz band.
Data Speed: Very low, primarily focused on voice communication.
Key Features: The first generation of mobile networks allowed for the basic cellular voice calls with roaming capabilities. This era saw the birth of the mobile phone as a consumer product, though it was large and bulky by today's standards.

Time Period: Early to late 1990s
Technology: Digital cellular networks

Frequency Band: Introduced multiple bands including 900 MHz and 1800 MHz.
Data Speed: Up to 64 kbps, supporting digital voice and text messaging (SMS).
Key Features: 2G brought about digital encryption of conversations, enabling more secure calls. It also introduced text messaging and the use of SIM cards.

Time Period: Late 1990s to mid-2000s
Technology: Enhanced data transmission

Frequency Band: Typically operates in the 2.1 GHz band.
Data Speed: Ranges from 144 kbps to several Mbps, enabling internet browsing, video calling, and multimedia streaming.
Key Features: 3G introduced mobile broadband services, allowing for faster data transfer rates and the introduction of services like video calling, mobile TV, and mobile internet access.

Time Period: Mid-2000s to 2010s
Technology: LTE (Long-Term Evolution)

Frequency Band: Uses a range of bands including 700 MHz, 800 MHz, 1800 MHz, 2.6 GHz, etc.
Data Speed: Several Mbps to hundreds of Mbps (peak speeds), enabling high-definition mobile internet access, online gaming, and video streaming.
Key Features: 4G offered significantly faster speeds than its predecessor, enabling rich multimedia experiences on mobile devices. The architecture was optimized for IP-based services and allowed for seamless connectivity.

Time Period: Late 2010s and beyond
Technology: New Radio (NR) in combination with LTE and other technologies

Frequency Band: Utilizes a wide range of frequencies including sub-6 GHz and millimeter wave (mmWave) bands.
Data Speed: Potential to reach several Gbps, enabling ultra-fast internet, augmented reality (AR), virtual reality (VR), and massive machine-type communications.
Key Features: 5G is designed to offer ultra-low latency, high reliability, and increased capacity. It supports a vast number of devices and aims to revolutionize various industries with applications like IoT, autonomous vehicles, remote surgeries, and more.
