[UKids] Re: "XOs cannot act as WiFi access points"

[Samuel Greenfeld]

If I recall correctly, Android devices cannot connect to Ad-hoc networks
out-of-the-box.  There may be some third party utilities which allow
certain devices to do this with varying levels of success.

Instead, either one device is configured as an AP, or a newer-than-Adhoc
standard called WiFi Direct is used.

Android devices may also communicate amongst themselves using Bluetooth,
although creating mesh networks/Internet gateways again would require
third-party utilities.  One such utility (Open Garden) partnered with OLPC
for the XO Tablet (

).

In general, generic Android to Android device communication was an unsolved
problem the last time I looked into this.
