The Gembird WiFi Extender transmits signals at a frequency of 2.4Ghz, which offers lower speeds compared to those that transmit on 2 (dual) or 3 (tri-band) frequencies. The 2.4Ghz frequency is the most common and has a wide range, but it is often congested by neighboring Wi-Fi signals, making it difficult for devices to communicate effectively. For managing multiple devices, a dual-band device can handle them more efficiently. The repeater can provide up to 300Mbps in total to devices connected to it. In practice, the actual speed that such a repeater of this generation (Wi-Fi 4) can offer to a device is closer to 50Mbps. For reference, a high-resolution 4K movie requires approximately 25Mbps. The speed that each connected device will have depends on factors such as distance, obstacles, the number of other devices connected, the presence of other networks in the same area, etc. It is a Wi-Fi 4 generation, an older generation recommended for use with few devices and for applications that do not require high speeds. A wired Ethernet connection offers a speed of 100Mbps, which is sufficient for all needs, for example, a high-definition 4K movie requires approximately 25Mbps.
