Unraveling the Wonders of 2G in IoT Connectivity
The Essence of 2G: Unveiling the Basics
In the intricate web of IoT connectivity, the term 2G often emerges as a pivotal player. But what exactly is 2G, and how does it contribute to the ever-evolving landscape of the Internet of Things?
Understanding 2G: A Primer
2G, or second-generation mobile networks, signifies a significant leap in wireless communication technology. It follows in the footsteps of 1G and paves the way for subsequent generations like 3G and 4G. But let's dive deeper into the core of 2G and its fundamental characteristics.
2G network speed is a key aspect that sets it apart. While not as swift as its successors, 2G offers reliable data transfer speeds, making it an essential component in the IoT connectivity ecosystem. The technology primarily utilizes circuit-switched networks, ensuring a stable and consistent connection.
Navigating the Terrain: What is 2G Internet and 2G Service?
When we delve into 2G internet, we encounter a technology that forms the backbone of mobile internet access for a multitude of devices. The speed of 2G internet may vary, but it is well-suited for applications that do not demand high bandwidth, such as text messaging and basic web browsing.
2G service encompasses a range of offerings, from voice calls and text messages to limited data access. Despite the advent of newer generations, 2G service continues to play a crucial role, especially in regions where advanced networks are not yet widespread.
The Technological Tapestry: What is the 2G Network and 2G Technologies?
The 2G network is a comprehensive infrastructure that facilitates voice and data communication. It operates on different technologies, including GSM (Global System for Mobile Communications) and CDMA (Code Division Multiple Access). These technologies lay the foundation for the seamless functioning of mobile communication systems.
2G technologies encompass a spectrum of advancements that contribute to the efficiency of the network. From improved voice quality to the introduction of SMS (Short Message Service), 2G technologies mark a significant evolution in the way we communicate wirelessly.
Summary
Le réseau 2G est un système de deuxième génération pour les communications mobiles. Les systèmes 2G offrent une qualité et une capacité vocales supérieures à celles des systèmes 1G. Les systèmes 2G fournissent la voix et une capacité de données limitée de 9,6 à 14,4 Kbps. Les systèmes 2G sont normalisés au niveau régional et offrent la possibilité d'une itinérance régionale (et non mondiale). Les normes 2G les plus importantes sont : GSM (Global System for Mobile communications), D-AMPS (Digital AMPS)/IS-136, PDC (Personal Digital Cellular) et cdmaOne/IS-95. Les systèmes 2G fonctionnent sur un commutateur de circuit. Des améliorations ultérieures ont rendu possible la commutation de données par paquets à plus haut débit. Ces possibilités, comme le GPRS pour le GSM, sont souvent appelées 2,5G.
Avec le General Packet Radio Service (GPRS), la 2G offre une vitesse de transfert maximale théorique de 40 kbit/s. Avec le système EDGE (Enhanced Data Rates for GSM Evolution), la vitesse de transfert maximale théorique est de 384 kbit/s. La principale différence entre les deux systèmes de téléphonie mobile (1G et 2G), est que les signaux radio utilisés par le réseau 1G sont analogiques, tandis que les réseaux 2G sont numériques. Les réseaux de télécommunications cellulaires 2G ont été lancés commercialement sur la norme GSM en Finlande par Radiolinja (qui fait maintenant partie d'Elisa Oyj) en 1991.
