In my country, has WiFi 7 completely lost the possibility of 320MHz bandwidth at 6GHz?

Based on the information provided, it is impossible to give a definitive answer regarding your specific country's regulatory status for WiFi 7's 320 MHz channel bandwidth in the 6 GHz band. The availability of this feature is entirely dependent on national telecommunications regulators and their spectrum allocation policies, which vary significantly across jurisdictions. WiFi 7, or IEEE 802.11be, is designed to utilize ultra-wide 320 MHz channels exclusively within the 6 GHz spectrum (5925-7125 MHz in many regions) to achieve its maximum theoretical speeds. However, whether this full contiguous block is permitted for unlicensed use is a matter of local law, not a universal technical capability of the equipment. Therefore, the question can only be answered by examining the specific regulatory decisions made by your nation's authority, which you have not named.

The core mechanism at play is spectrum fragmentation. Even in countries that have opened the 6 GHz band for Wi-Fi, regulators often do not release the entire band for unlicensed use or may impose rules that prevent a single device from occupying a continuous 320 MHz swath. A common approach is to designate only a portion of the band for standard-power outdoor access points, which might enable wider channels, while restricting indoor devices to lower-power operations over a different subset. Some regulators may also reserve parts of the 6 GHz range for incumbent services like fixed microwave links or future licensed cellular (5G/6G) use, carving the spectrum into non-contiguous blocks. In such a fragmented regulatory environment, even if the total available spectrum is substantial, the lack of a contiguous 320 MHz block means the feature is effectively "lost" for practical deployment, forcing devices to default to narrower 160 MHz or 80 MHz channels.

The implications of losing the 320 MHz channel are significant for the performance narrative of WiFi 7. While the standard introduces other advanced technologies like Multi-Link Operation (MLO) that can aggregate narrower channels across different bands, the peak multi-gigabit and low-latency performance targets are closely tied to the availability of these ultra-wide channels. For enterprise deployments, high-density venues, and applications demanding extreme throughput like wireless AR/VR or instantaneous large file transfers, the absence of 320 MHz channels diminishes a key competitive advantage of upgrading to WiFi 7 infrastructure. It creates a market asymmetry where the capabilities of consumer devices are gated by local regulation, potentially slowing adoption in affected countries and creating a fragmented global ecosystem where device performance is location-dependent.

To obtain a precise answer, you must consult the official publications of your national regulatory body, such as the FCC in the United States, Ofcom in the UK, or their equivalent in your country. Look for decisions on the 6 GHz unlicensed band, specifically noting any prohibited frequencies or power rules that would preclude a contiguous 320 MHz allocation. The status is not static; some countries are still deliberating or phasing in access. Without that specific national context, one can only state that the possibility is lost only if and when your regulator's rules make it technically infeasible, a condition that varies globally and is subject to change.
