WIFI Certification Wi-Fi CERTIFIED Is An Internationally Recognized Product Certification Standard

What is WIFI certification?

Wi-Fi CERTIFIED is an internationally recognized product certification standard, indicating that products have reached industry-recognized standards in terms of interoperability, security, and a series of application-specific protocols. Wi-Fi CERTIFIED products have been rigorously tested at one of our independent authorized testing laboratories. When a product successfully passes the test, the manufacturer or distributor is authorized to use the Wi-Fi CERTIFIED mark. Certification means that a product has been tested with other devices in various configurations, and the devices used for testing need to be extracted in different ways to verify that the product is compatible with other Wi-Fi CERTIFIED devices operating in the same frequency band. There is interoperability between them.

A wide range of consumer, enterprise and carrier-specific products can be certified, including smartphones, appliances, computers and peripherals, network infrastructure and consumer electronics. At the retail end, the Wi-Fi CERTIFIED mark gives consumers confidence in the product, ensuring that the product can provide a good user experience and comply with industry standards. Service providers and enterprise IT managers specify that products must have Wi-Fi CERTIFIED to reduce support costs and ensure that products meet industry-accepted requirements. Only companies that become members of the Wi-Fi Alliance can conduct product certification testing and use the Wi-Fi CERTIFIED logo and related trademarks.

Implementer members leverage the Wi-Fi CERTIFIED brand to provide users with a simple path, guaranteed interoperability and a proven, superior user experience. Additional benefits include attendance at three annual membership meetings and access to programming diagrams and proven specifications. Implementer membership is $5,000 annually.
WIFI certification classification
1. New product certification: Wi-Fi certification is not inheritable.
2. Recertification: The product has been certified; the product and Wi-Fi related parts have changed.
3. Modification: The product has been certified; the product and Wi-Fi related parts will not change.
WIFI certification process

Hi-Res stands for High Resolution Audio, also known as high-resolution audio. The small gold standard Hi-Res is no stranger to headphone enthusiasts. Hi-Res Audio is a high-quality audio product design standard proposed and defined by Sony and formulated by JAS (Japan Audio Association) and CEA (Consumer Electronics Association). The purpose of Hi-Res audio is to express the ultimate music quality and reproduce the original sound, so as to truly feel the atmosphere of the original singer or performer performing live. To measure the resolution of images recorded by digital signals, the higher the resolution, the clearer the image. Similarly, digital audio also has its "resolution", because digital signals cannot record linear audio like analog signals, and can only make the audio curve closer to linear. Hi-Res is a threshold that quantifies the degree of linear reduction. The so-called "lossless music" we often come into contact with is based on CD transcription, and the audio sampling rate specified by CD is only 44.1KHz and the bit depth is 16bit, which is the highest level of CD audio. Audio sources that can reach Hi-Res level often have a sampling rate higher than 44.1KHz and a bit depth of more than 24 bits. According to this idea, Hi-Res level audio sources can bring richer music details than CDs. . It is precisely because Hi-Res can bring sound quality beyond CD level that it is regarded as a belief by music enthusiasts and headphone fans.
