Wi-Fi G DEMO BOARD
USER’S GUIDE
Chapter 4. Description of Modes of Operation
4.1
SoftAP NETWORK
On starting the demo, the factory default conditions has the product start up as a
SoftAP without security. This means that all the network information that is being con-
figured on the device is going over-the-air in the open. For most applications, unless
another user is specifically attempting to listen in on this network, the potential security
impact is minor. However, for applications that require baseline level of security, WEP
can be employed on the network.
SoftAP is the centralized coordinator for the network. With MRF24WG0MA IEEE
802.11 b/g Wi-Fi Transceiver Module firmware version 0x3107 and future releases, it
supports Wired Equivalent Privacy (WEP) (40-bit/104-bit) security.

4.2
AD HOC NETWORKS
Ad Hoc networks are peer-to-peer networks with no centralized coordinator for the net-
work. All the devices share the responsibilities of keeping the network running. Accord-
ing to 802.11 specifications, ad hoc network only supports 802.11b rates of 1 Mbps, 2
Mbps, 5.5 Mbps and 11 Mbps.
One downfall of ad hoc networks is that typically security is not employed on them.
The MRF24WG0MA IEEE 802.11 b/g Wi-Fi Transceiver Module can secure an ad hoc
network with Wired Equivalent Privacy (WEP) (40-bit/104-bit) security, like most of the
laptops and ad hoc devices. Very few devices in the market can secure an ad hoc net-
work with Wi-Fi Protected Access (WPA) level security due to tremendous overhead.
For most applications, unless another user is specifically attempting to listen in on this
network, the potential security impact is minor. However, for applications that require
baseline level of security, WEP can be employed on the network.
Most Android devices do not support ad hoc networks.

Wi-Fi DIRECT NETWORKS
Wi-Fi Direct network is a peer-to-peer (P2P) network. It enables the user to configure
a secured wireless network between several devices, such as smart devices, laptops
or computers with wireless network adapters, without using an access point (AP).
Wi-Fi Direct supports Wi-Fi Protected Setup (WPS) connection method, which is
known as the WSC (Wi-Fi 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 determines which devices become group
owner (GO) or group client (GC). The GroupOwnerIntent field in the P2P information
element (IE) indicates the level of desire to become the GO. The higher the value, the
higher the desire to be the GO.
MRF24WG0MA IEEE 802.11 b/g Wi-Fi Transceiver Module only supports the role of
GC.
Wi-Fi Direct does not support 802.11b.
