Karma is a new 4G Wireless Provider that will be introducing a hotspot that uses Clearwire Network to provide multiple users the ability to use the Internet. Karma makes your hotspot into an open Wi-Fi network. When a new user joins, they are taken to a personalized page about the owner of the hotspot. Strangers can then sign in with their Facebook account and get 100MB of free browsing. For every user who does that, the owner of Karma gets 100MB of free data credited to his or her account. Karma has also just announced a deal with American Airlines, which will offer free Karma hotspots to frequent fliers.
