Recent reports indicate that Huawei has developed an advanced data encoding technology that significantly outperforms NATO’s current protocols in underwater communication tests. Huawei’s technology, known as Higher-Order Polarization Weight (HPW), was successfully tested by the People’s Liberation Army (PLA) and Xiamen University in the South China Sea. This system enables more efficient and stable data transmission over long distances underwater, surpassing the capabilities of the older NATO JANUS system. This development highlights China’s advancements in underwater communication, with potential implications for military and geopolitical strategies​,

The term “Higher-Order Polarization Weight (HPW)” refers to an advanced data encoding method developed by Huawei. This technology enhances underwater communication by compressing and transmitting data more efficiently on a single carrier wave, reducing power consumption and noise. It has shown superior performance compared to older technologies like NATO’s JANUS system, particularly in long-distance underwater transmissions.

How Higher-Order Polarization Weight (HPW) Works

Higher-Order Polarization Weight (HPW) is an advanced data encoding technology developed by Huawei, primarily aimed at improving underwater communication. This technology allows data to be represented in a more compact form, using polarization properties of waves to encode information efficiently. HPW minimizes the need for splitting data across multiple channels, which simplifies transmission and reduces both power consumption and noise. The system is particularly effective in challenging environments like deep-sea communications.

During tests, HPW was attached to underwater communication devices, where it transmitted data at speeds of 4000 bits per second over distances of up to 30 kilometers, even at depths of 3000 meters. This marks a significant improvement over older systems like NATO’s JANUS, which operates on outdated OFDM technology that requires more power and has higher noise levels over long distances.

Implications for NATO

For NATO, the advent of HPW represents a potential risk in terms of military and communication superiority. The superior performance of HPW in underwater environments suggests that adversaries equipped with this technology could achieve more reliable and secure communications in subaquatic settings. This could undermine NATO’s current capabilities in underwater surveillance and communications, necessitating advancements or new countermeasures to maintain strategic parity.

In summary, HPW’s efficiency and reliability could challenge NATO’s existing technologies, pushing for innovation in military communication systems to address these emerging threats.
