From Bradley Mitchell, your Guide to Computer Networking
You may have noticed a capability called Wi-Fi Direct listed as a feature of some newer wireless networking products. Wi-Fi Direct allows Wi-Fi devices to communicate with each other in direct, peer-to-peer fashion instead of through a common wireless router or access point. It's been around for awhile, but it seems not too many people know about it. Do You Use Wi-Fi Direct?

Where's Your Favorite Wi-Fi Hotspot?

Hotspots are a great way to get to the Internet when you're away from home. While hotspots can be found almost anywhere, many of us tend to have a favorite location they visit most frequently. Tell us about yours.
