The WIFI Extension has been superseded by the superior WIFI Extension 2.0. The old WIFI Extension is still available, but you should only use it if you need an external antenna connector. See the blog post about the WIFI Extension 2.0 for a more detailed comparison.
With this WIFI Extension you can control Bricks and Bricklets wirelessly over your mobile phone, tablet or your PC. For the Master Extension concept please take a look at the general description. The Extension is equipped with a GainSpan GS1011MEES Wi-Fi module with an internal power amplifier which allows for superior range compared to other Wi-Fi modules.
The devices supports two modes. In Full Speed Mode the device Wi-Fi transceiver is always on. New incoming data will be immediately handled. In Low Power Mode the devices is not always on, the transceiver enters sleep mode after each message. This leads to a significantly lower power consumption and data throughput.
Since the device itself handles TCP/IP packages generated by the API, it is possible to connect directly from your controlling device (mobile phone, tablet, (embedded) PC). A Brick Daemon is not necessary.
To use the WIFI Extension a Master Brick is mandatory. The RED Brick is currently not supported. If you want to use other Bricks, you can build a stack and plug them also on top of the Master Brick. If you want to use Bricklets you can attach them to the Master Brick or to other Bricks in the stack. From the programming perspective this is completely transparent, i.e. all Bricks and Bricklets can be used exactly the same way as if they were connected to your controlling device via USB.
