Wi-Fi, standing for “Wireless Fidelity”, is a wireless communication technology that uses radio frequencies to transmit data. Established in 1997 by the Institute of Electrical and Electronics Engineers (IEEE) as the 802.11 standard, Wi-Fi has become synonymous with wireless internet access.

Automotive industries, recognizing the increasing demand for on-the-go connectivity, began integrating Wi-Fi capabilities into vehicles in the 2010s. This allowed vehicles to become mobile hotspots, ensuring continuous internet access during journeys, and fostering a new dimension of in-car entertainment and functionality.

Wi-Fi operates by broadcasting data using radio waves, with a frequency of either 2.4 GHz or 5 GHz. A device, when within range, can connect to this network, facilitated by a router. Signal strength and data transfer rates diminish with increased distance from the source or physical obstructions.

In vehicles, Wi-Fi offers an array of functionalities. It enables passengers to remain connected, allowing for streaming of entertainment, real-time navigation updates, and even work-related tasks. Moreover, the technology plays a pivotal role in the realm of connected cars. Features such as over-the-air software updates, remote diagnostics, and vehicle-to-everything (V2X) communication are made possible through Wi-Fi.

As the automotive industry evolves towards greater connectivity and the emergence of autonomous vehicles, Wi-Fi’s significance is expected to grow. It not only augments passenger experience but also forms the backbone of sophisticated vehicular communication systems, melding the realms of transportation and digital connectivity.
