WiFi connectivity so far has mostly dependendent on a WiFi hotspot or access point. Point to point or peer to peer connectivity for mobile devices today still relies heavily on Bluetooth. Currently the WiFi alliance is completing its specification for WiFi Direct which allows Peer to Peer connectivity. This would definitely offer faster file transfers and open up possibility of WiFi P2P gaming and other peer to peer content delivery over WiFi.
Symbian is looking at implementing this in 2011 and there’s even a implementation guide to do this. So far there isn’t any apps yet but it is expected to make its way by next year. We don’t know why it took so long for WiFi to do this but it is better late than never.

Apple is currently looking into instant product research capabilities for the iPhone which can be implemented via a simple bar code or even Near Fields Communication (NFC). What they plan to achieve is to allow users to get reviews, advise and detail information of products easier from a mobile device.
Apple had filled couple of patents for such use called Products+. The possibility is endless and the post by Apple insider had mentioned a number of interesting uses such as scanning codes on products for review or even using it to add events to your calendar. For barcode scanning, we don’t see what is stopping Apple of acheiving that now as even Google has being doing it through Google Goggles. All they need is to have a software that works and an online engine to transate that code to what it was intended for.
