Frank Hanzlik, managing director of the Wi-Fi Alliance, said that the market was in danger of being fragmented by a number of different "Draft N" or "Pre-N" products. The products get a lot of attention because they claim faster speeds and greater range, however some of the do not work that well together.
Initially, the alliance indicated it wouldn't certify the interoperability of the pre-N products until the Institute of Electrical and Electronics Engineers is able to test this. However it looks like the IEEE will not be able to certify the testing of the standard quickly enough.
Hanzlik said that the Wi-Fi Alliance will still go ahead with the plan to certify products in the first half of 2007. When the IEEE approves a final 802.11n standard in March 2008, the alliance will conduct a second phase of testing.
Most of the manufacturers think that the two-tiered approach to certification will give the new 802.11n a bit of a boost.
