Speed may be the goal, but interoperability is the number one concern among 802.11n vendors and user-hopefuls. The 802.11n standard is hoped to achieve markedly faster transmission speeds with higher quality at longer distances and with less interference. Unfortunately, current 802.11n draft-compliant products have tested at less than desired levels, even coming short of results achieved by non-compliant products. Truly certified products are expected to be available the first half of 2007; early buyers are warned their 2006 purchases may not be compatible with the final version.
