1024-QAM and BSS Coloring: Dual Assurance of speed and anti-interference
To achieve a higher transmission rate, the ComFi C21E 4G WiFi6 Wireless CPE adopts 1024-QAM (Quadrature Amplitude Modulation) coding technology. Compared with 256-QAM of WiFi5, 1024-QAM can carry more data information within a unit of time, and the theoretical transmission rate has increased by nearly 25%. This means that in good signal conditions, you can enjoy an ultra-fast download experience closer to 300Mbps. Whether it’s downloading large games, Blu-ray original disc movies, or cloud synchronization of large files, it can all be completed in an instant, completely bidding farewell to long waits.
In today’s urban environment where high-rise buildings are everywhere and wireless network signals are ubiquitous, signal interference is the main culprit affecting network stability. ComFi C21E, as an advanced 4G WiFi6 Wireless CPE, introduces BSS Coloring (Basic Service Set Coloring) technology. This technology ingeniously “paints” adjacent WiFi networks with different “colors”. When your device receives a signal, it can easily identify whether it is from your own router (the same color) or your neighbor’s router (different colors). For signals of different colors, the device will regard them as interference and directly ignore them, thereby effectively avoiding co-frequency interference and significantly improving network performance and stability in dense environments. This feature enables ComFi C21E to maintain excellent signal purity and connection quality even in complex living environments such as apartment buildings.
