L'évolution des technologies de communication mobile, de la 4G à la 5G, ne se résume pas à une simple augmentation de vitesse. Elle implique une amélioration globale de l'architecture réseau, de la latence, de la capacité et des cas d'utilisation. Voici les différences clés et un tableau comparatif.
The RJ45 (Registered Jack 45) connector is one of the most ubiquitous components in modern networking. Known for its reliability and versatility, it serves as the standard interface for Ethernet cables, enabling wired internet connections in homes, offices, data centers, and industrial systems. This article explores its design, evolution, and critical role in global connectivity.
Die mobile Kommunikation hat sich von 4G über 4G LTE bis hin zu 5G kontinuierlich weiterentwickelt. Jede Generation bringt neue Möglichkeiten, doch die Unterschiede in Geschwindigkeit, Latenz und Anwendungsgebieten sind entscheidend. Hier eine detaillierte Analyse.
A modem (Modulator-Demodulator) is a critical device in computer networks that converts digital signals into analog signals for transmission over analog channels (e.g., telephone lines, cables, or radio waves) and vice versa.
CAN FD (Flexible Data-rate), short for "CAN with Flexible Data-rate," represents a protocol-layer upgrade to traditional CAN. Notably, CAN FD retains the original physical layer while enhancing the communication protocol.
With the rapid development of IoT technology, an increasing number of connectivity methods and communication protocols are being applied to various smart devices. Among them, WIFI and LoRa, two wireless communication technologies with distinct technical features, have become indispensable components in IoT applications.
The Universal Serial Bus (USB), conceived in 1994, has undergone multiple major upgrades from its initial USB 1.0 to the current USB 4.0. Each iteration brought not only leaps in transfer speeds but also expanded functionality and application scenarios.
With the advancement of technology, the application of drone technology in agriculture has become increasingly widespread. Drones in agriculture have evolved from simple aerial photography to precision farming, crop health monitoring, and field inspection, among other areas.
According to IoT Analytics, a leading market research firm, the number of active IoT connections worldwide is projected to exceed 27 billion by 2025. This massive scale drives continuous innovation and market growth in communication interface technologies, particularly in low-power wide-area networks (LPWAN), cellular IoT (e.g., NB-IoT, LTE-M, 5G RedCap), Wi-Fi 6/7, Bluetooth Low Energy (BLE), and industrial bus interfaces.
