Following the finalization of the reƖ-N (802.11n) standard, the Wi-Fi Alliance, a nonprofit group that tests and certifies reƖ products to ensure they interoperate, launched on Tuesday its new test program that supports the final specs of the standard.

This certification is still necessary because, according to Kelly Davis-Felner, marketing director of the Wi-Fi Alliance, the final specs include a lot of options and items that vendors could interpret differently, which could lead to products that don't work with each other. "Our certification program ensures that the product conforms with the final standard and interoperates with others." Felner added.

The new certification program is basically the same as the one used for the Draft N 2.0, with the addition of a few tests for new optional features.
