     Wi-Fi Peer-to-Peer (P2P) and SoftAP for smxWiFi™


Wi-Fi Peer-to-Peer (P2P) and SoftAP allow easy, direct connection among Wi-Fi devices, anywhere. There is no need for an Access Point. Through negotiation, one device becomes the Group Owner and the other the client. Initiation of the connection is designed to be quick and easy. Implementation does not require addition of new hardware, allowing existing smxWiFi users to add them to their products with just a software update.

Wi-Fi Peer-to-Peer is a protocol designed to replace the legacy ad-hoc (IBSS) protocol for interconnecting Wi-Fi devices. Improvements over ad-hoc include easier connection and the latest security, 802.11i. It was designed to satisfy the growing need for dynamic connections among groups of electronics. It allows OEMs to create products that can interoperate with each other and with common consumer devices, such as phones, tablets, cameras, and printers. As with any Wi-Fi device, the range is up to 200m, making connection convenient even when devices are not in immediate proximity to one another.

SoftAP gives a device limited Access Point capabilities. When combined with Wi-Fi P2P, it allows the device to be the Group Owner. Without it, a device can participate only as a client.

Learn how protocols supported by smxWiFi correspond to the certification programs of Wi-Fi Alliance, such as Wi-Fi Direct™, Wi-Fi Protected Setup™, Wi-Fi Protected Access®, WPA™, and WPA2™.
