The Wi-Fi Alliance announced that products from Atheros, Broadcom, Intel, Ralink, Realtek, and Cisco will be the first Certified Wi-Fi Direct hardware in the test bed for the new wireless networking standard.
The key feature of new Wi-Fi Direct standard is that it lets devices with 802.11 wireless radios communicate directly with one another without the need of a wireless router between them. Wi-Fi Direct devices near one another can transfer content at speeds 25 times faster than they could with Bluetooth 2.0. As a result, the standard has been referred to as a Bluetooth Killer in IEEE meetings.
Because it's a Wi-Fi Alliance software standard, it has the added benefits of legacy compatibility with standard Wi-Fi client devices, support for WPA2 security, and widespread support from the hardware industry.
Broadcom's first Wi-Fi Direct certified product is a multi-antenna dual-band 802.11n PCIe card, but the company's participation in these early stages of development is significant because it's a majority player in the 802.11n Wi-Fi chipset business for mobile handsets.
