Huawei data encoding tech outperforms NATO in underwater communication test
News regarding Huawei suggests that the company has outstripped NATO with its data encoding tech in an underwater communication test. The Chinese phone maker achieved significant results over outdated technology in the native region.
As per the details, China is planning to expand its wireless communication tech from air to sea. To meet this goal, the PLA (People’s Liberation Army) 92150 unit and the Xiamen University recently tested data encoding and transmission underwater.
The project persons used the Huawei higher-order polarization weight (HPW). Launched in 2017, HPW is a powerful data encoding method that represents data in a more compact form. It works as a major component of communication equipment.
When attached to an underwater communication machine, it doesn’t split data and easily adjusts the data on a single carrier wave for transmission. This ultimately reduces power consumption and requirements for any other complex operations.
HPW not only simplifies data transmission but also reduces noise in underwater scenarios. Huawei categorized this data encoding method under polar codes.
Inputs reveal that the project persons held the submarine communication test in the South China Sea (water depth = 3000 meters). During the test, the scientists attached this data encoding tech to a new device and pushed it into the water. They also placed a hydrophone 1000 meters below to check signal transmission.
In outcomes, the scientists received data transmission at a speed of 4000 bits per second from a 30km away ship. One of the scientists at Xiamen University – Professor Tong Feng said that Huawei’s encoding method has been precise and stable throughout the test. It eventually made a new record in China’s history.
NATO Technology
Earlier China used NATO JANUS for data encoding and supporting communication equipment. It is capable of covering 28km of distance with a sound wave frequency of 900Hz. Thus, it used to transfer a small amount of data amid equipment.
JANUS runs on OFDM technology that initially divides the data streams and then modifies them on various carrier sound waves to bring high-speed transmission in a short distance. But the tech is quite outdated and requires higher operating power.
Another reason to replace OFDM technology is that it uses quite compound and expensive elements. It further increases noise due to long distances which affects the communication performance.
The new underwater communication test between Huawei data encoding tech and NATO protocol shows that China is seeking strength for its future military and geopolitical power. With high-end technologies and AI-backed drones, the region could develop a better army for future challenges.
