1.7.3 WiFi Direct (Peer-to-Peer (P2P)) Network
Figure 1-3 provides a typical example of local network, WiFi Direct (peer-to-peer (P2P))
network. WiFi Direct does not support 802.11b, therefore only MRF24WG0MA/B Wi-
Fi
®
PICtail™ can support such network types.
FIGURE 1-3: WIFI DIRECT (PEER-TO-PEER P2P) NETWORK
WiFi Direct allows you to configure a secured wireless network between several
devices, such as smart devices, laptops or computers with wireless network adapters,
without using an AP. WiFi Direct supports WiFi Protected Setup (WPS) connection
method, which is known as the WSC (WiFi Simple Configuration) Config Methods in
the Wi-Fi Peer-to-Peer (P2P) Technical Specifications, in particular WPS Push Button
method with WPA2.
From the negotiation process, each device will determine which devices become group
owner (GO) or group client (GC). The “GroupOwnerIntent” field in the P2P information
element (IE) will indicate the level of desire to become the GO. The higher the value,
the higher the desire to be the GO. Since MRF24WG0MA/B supports the role of GC
only, it implies
GroupOwnerIntent=0 (P2P IE). Within each WiFi Direct network, there
can be only one GO, similar to only single AP in the infrastructure network.
