I'll be reviewing both single and dual-band products, although I continue to recommend dual-band products for the flexibility that operation in the 5 GHz band provides. Reviews will be limited, however, only to products that have received the Wi-Fi Alliance's 11n Draft 2.0 Certification.
This doesn't mean that Wi-Fi Certified products are fully-baked by any means. But at least they have been tested and certified to a reasonable level of interoperability and feature support. And while the Alliance doesn't make details of the certification test suite available outside of its membership, this white paper provides some insight into the testing that is done for Draft 11n Certification.
