Atheros, Broadcom claim 802.11n compatibility
The two have verified that Atheros' XSPAN and Broadcom's Intensi-fi chipsets work together at throughput speeds greater than 100 Mbps, using mandatory modes of the IEEE 802.11n specification (draft 1.0).
Early interoperability testing can help assure the end-market that once 802.11n is ratified, the technology will in fact be market-ready. In the past, however, some OEMs did not wait for official ratification of previous Wi-Fi versions in order to get a jump on the market. The news from Atheros and Broadcom could be interpreted by some OEMs as a signal they can try the same strategy with 802.11n.
The 802.11n version of Wi-Fi is expected to be used not only in PCs and networking gear, but also by mobile and entertainment devices, expanding the market for 802.11n chips and raising the stakes for chip companies.
Atheros and Broadcom said theirs was the first in what is expected to be a series of interoperability tests conducted with leading wireless companies to broaden the scope of interoperable systems. Over the coming months, the testing will lay the groundwork for Wi-Fi Alliance testing when the organization's certification process is finalized.
