Optimizing WiFi Network with 5 GHz Band

The 5 GHz band generally provides clearer and faster wireless connections compared to the 2.4 GHz band, making it ideal for reducing congestion in home Wi-Fi networks.

In European regions, the 5 GHz band offers a range of 515 MHz for free use, enabling more available channel options for wireless networks.

Dynamic Frequency Selection (DFS) channels in the 5 GHz band can automatically switch to other frequencies if they detect potential interference from devices like radar systems.

The Institute of Electrical and Electronics Engineers (IEEE) is responsible for establishing and maintaining the standards for wireless communication protocols, including the 802.11 series for Wi-Fi networks.

Transmitter Power Control (TPC) in the 5 GHz band helps minimize the transmission power used by Wi-Fi devices, ensuring smooth communication and reducing interference with other nearby devices.

The 5 GHz band features different zones with distinct usage rules to optimize Wi-Fi network performance and prevent interference with other services like radar systems.

The 5 GHz band offers 19 channels with a bandwidth of 20 MHz, providing flexibility in choosing the most suitable channel for your Wi-Fi network.

Movistar's HGU router, by default, uses a channel bandwidth of 80 MHz in the 5 GHz band, enabling higher data transfer speeds.

With an 80 MHz channel width, only three effective channels are available in the 5 GHz band, due to overlap between neighboring channels.

Channels 36, 40, 44, and 48 in the 5 GHz band are specifically allocated for Wi-Fi networks, ensuring consistent and reliable performance without interference from other services.

A DFS-designated channel can be shared with other public services like radar systems, requiring automatic adjustments to avoid interference.

When powered on, 5 GHz Wi-Fi routers need to scan DFS channels for radar signals before transmitting, leading to a potential delay in network appearance.

Devices like Amazon Fire TV Stick lack the ability to automatically switch channels when detecting radar signals, preventing them from connecting to DFS channels.

Routers monitor DFS channels during operation to detect radar signals, ensuring smooth Wi-Fi connectivity by adjusting channels if necessary.

If radar activity is detected, routers need to find a new clear channel, which can extend the scanning and channel selection process indefinitely.

Amazon Fire TV Stick, a low-cost device, lacks the capability to automatically adjust channels when detecting radar signals, leading to inability to connect to networks configured on DFS channels.
