Road to 5G…
1G/1st generation - 1G, or first generation, refers to the first generation of cellular network technology. It was developed in the 1970s and 1980s and was the first generation of analog cellular networks. 1G systems were based on analog radio technology and used circuit-switched voice communication.
The first commercial 1G network, the Motorola DynaTAC 8000X, was launched in 1983 by the American carrier AT&T. It had very limited capabilities, only allowing for 30 minutes of talk time and 8 hours of standby time. It was also quite bulky, weighing in at 2.5 pounds (1.1 kg) and measuring 13 inches (33 cm) tall.
1G technology had a number of limitations, including poor call quality, low capacity, and limited coverage area. It was also relatively expensive, and the phones were large and heavy. Despite these limitations, 1G networks were an important step forward in the development of mobile communication technology, as they enabled people to make phone calls from anywhere.
2G/2nd generation - 2G, or second generation, refers to the second generation of cellular network technology. It was developed in the 1980s and 1990s and was an improvement over the first generation (1G) of cellular networks. 2G networks were based on digital radio technology and used packet-switched data communication.
The first 2G network, GSM (Global System for Mobile Communications) was launched in Europe in 1991 by the carrier, Radiolinja (now part of Elisa Oyj) in Finland. 2G networks provided several improvements over 1G networks, including improved call quality, increased capacity, and wider coverage area. 2G also introduced the concept of text messaging (SMS) which was not possible on 1G.
2G technology also enabled the development of new services such as mobile internet and email, and laid the foundation for the development of mobile banking and mobile commerce. Additionally, 2G networks were more energy efficient, which allowed for smaller and more portable phones.
However, 2G also had its own limitations, such as low data transfer rates, which made it difficult to support more advanced applications such as streaming video or music.
3G/3rd generation - 3G, or third generation, refers to the third generation of cellular network technology. It was developed in the 1990s and 2000s and was an improvement over the second generation (2G) of cellular networks. 3G networks were based on digital radio technology and used packet-switched data communication.

internet access and the ability to support more advanced applications such as video streaming and mobile internet browsing. 3G networks also had better support for multimedia services and provided wider coverage areas and improved call quality.
3G networks also introduced the concept of mobile broadband, which greatly expanded the capabilities of mobile devices, making it possible to browse the internet, watch videos, and use social media on the go. Additionally, 3G technology also introduced the concept of mobile data services, allowing people to access information and services without the need for a wired connection.
4G/4th generation - 4G, or fourth generation, refers to the fourth generation of cellular network technology. It was developed in the early 2000s and was an improvement over the third generation (3G) of cellular networks. 4G networks are based on digital radio technology and use packet-switched data communication.

What is edge computing?
Edge computing refers to a distributed computing paradigm in which data, compute, storage and applications are brought closer to the sources of data, such as devices, sensors, and gateways. This allows for processing of data to be done closer to where it is generated, rather than in a central location such as a data center or cloud.
In edge computing, data is processed and analyzed at the edge of the network, near the source of the data, rather than being sent to a centralized location for processing. This reduces the amount of data that needs to be sent over the network, which can help to reduce latency, increase security, and reduce costs.
Edge computing is often used in combination with cloud computing, where data is first processed at the edge, and then sent to the cloud for further analysis, archiving or backup.
Edge computing is particularly useful in cases where low latency, high bandwidth, or high availability is important. It can be used in a wide range of applications such as IoT, autonomous vehicles, augmented and virtual reality, and industrial automation.
One of the main advantages of edge computing is that it allows for real-time data processing and decision-making, which is critical for many applications such as autonomous vehicles, industrial automation, and IoT. Additionally, edge computing enables the development of new use cases which were not possible with a centralized architecture, such as low-latency video processing, or video analytics in a remote location.
In summary, Edge computing is a distributed computing paradigm where data, compute, storage and applications are brought closer to the sources of data such as devices, sensors and gateways, this allows for processing of data to be done closer to where it is generated, rather than in a central location such as a data center or cloud.
