WiFi Direct allows devices to communicate directly with each other using methods similar to traditional WiFi, except for the use of a central access point. Instead, the devices use a "Software Access Point" (Soft AP). Each device will have a radio transceiver, usually on a chip, which uses software to create an access point within the device itself.
As of December 2012 there have 1520 certifications issued for Wi-Fi Direct products to 48 companies for a variety of products. This paper will examine some of these companies and the products they offer. The companies range from consumer electronics companies to smartphone manufacturers to semiconductor manufacturers. The products range from smartphones to televisions to tablet PCs.
