WiFilähetin

WiFilähetin is a Finnish term that translates to "Wi-Fi transmitter" or "Wi-Fi broadcaster." It refers to any device that emits or transmits Wi-Fi signals, enabling wireless network connectivity. This encompasses a wide range of hardware, from consumer-grade routers found in homes and offices to more industrial or specialized transmission equipment. The primary function of a WiFilähetin is to create a wireless local area network (WLAN) by broadcasting radio waves on specific frequencies, typically 2.4 GHz and 5 GHz, allowing compatible devices such as smartphones, laptops, and tablets to connect to the internet or a local network without physical cables.

The functionality of a WiFilähetin can vary. Simple devices might only broadcast a network, while more advanced models offer features like network security protocols (WPA2, WPA3), Quality of Service (QoS) settings to prioritize certain types of traffic, and the ability to create multiple virtual networks (SSIDs). In a broader sense, the term can also extend to devices like Wi-Fi repeaters or range extenders, which capture and re-transmit existing Wi-Fi signals to improve coverage in larger areas. The deployment of WiFilähettimet is fundamental to modern wireless communication infrastructure.
