WiFi is basically a radio network. This means that the signals are transmitted from the router to the end devices in a certain frequency range. The 2.4 GHz band is still frequently used for WiFi today. The problem: This band is also used to send and receive data by other applications such as Bluetooth. If many devices are transmitting on this frequency, however, things quickly become “tight” on this band, which may lead to interference. You can imagine the whole thing as a “data highway” on which all vehicles are driving on one lane. At a certain point, this lane is full and traffic is barely able to flow.
Dual-band WiFi offers high flexibility
In order to accelerate data transmission, the 5 GHz band has been used for WiFi for several years. With two simultaneously connected networks (dual WiFi), the router can provide significantly more devices with stable and fast data – provided that your end device supports the 5 GHz band. If this is the case, you as the user will immediately notice a significant increase in WiFi performance. The reasons for this are that the 5 GHz band is generally used less frequently and has less interference, allowing significantly more data to be transferred. With dual-band WiFi, the “data highway” becomes larger and wider, and the devices can “change lanes.” By the way: In the Mesh WiFi from FRITZ!, the end devices automatically change frequencies – thanks to Band Steering.
Three radio units for optimum data transmission
The special feature of the new FRITZ!Repeater 3000 is its third radio unit, hence the term “tri-band.” The repeater operates in both the 2.4 GHz band and in two separate 5 GHz bands. The highlight is that the repeater communicates solely with the FRITZ!Box via the additional 5 GHz band. Optimal communication between the router and repeater guarantees an ideal connection of all devices in the WiFi mesh. The big advantage for your home network: The two other radio units of the FRITZ!Repeater 3000 (2.4 and 5 GHz) are thus free for data transmission to all other end devices. This guarantees great range and high data throughput, and your WiFi devices are given the green light in the home network.
