Location and Intended Users

Users of XOs, inside and outside of school.

Requirement: 5-10 million laptops to be distributed in 2008 with 1 server per 100 laptops and 3 active antennas per server.

Motivation

• Active Antennas are critical for the project and are required for the school server.
• Every school server requires 3 Active Antennas.
• Better connectivity will generate more use for the XO outside of school
• This particular antenna extends the range of the mesh, thus extending wireless connectivity for everyone in range, not just for the XO plugged into it.
• The mesh networks seem to have limited signal within about 100m between two laptops

Disadvantages

• Cost
