Tasks Accomplished

• Agreed Upon Modular Design (Whole Team)
• Soekris Single-Board Computer (SBC) 4521
• Operating system loaded onto a compact-flash (CF)
  card and attached to the board
• 2 Wireless 802.11 radio cards with external
  antenna ports plugged into the board
• Lithium-Ion or Sealed Lead Acid (SLA) battery for
  power
• Solar panel to recharge battery during daytime
  hours
• Antennas for communicating with home base as
  well as for supporting local clients
• Henry communicated with the mentor, coordinated
  team meetings, revised SOW
• Andrew tested and configured the board
• Dominic researched the battery options (Sealed
  Lead Acid vs. Lithium-Ion)
• David researched the solar panel

Revised Statement of Work

• Design and construct a working prototype of a
  solar-powered Deployable Wireless Access Point
  (DWAP) using existing commercial technologies
• The operational prototype must act as a router
  and a repeater and provide TCP/IP network access
  to remote wireless clients
• Prototype must feature a solar-based charging
  system that will restore full battery strength in
  5 hours fully-charged battery must last at least
  14 hours
• Range must be a minimum of 0.5 miles (from home
  base) and offer a radius of coverage (for local
  clients) of at least 500 feet
• Bandwidth between the clients themselves and to
  the remote home base must be at least 1 Mbps
  (106 bits per second)
• Weight of the prototype must be lt 20 lbs.
• Total cost of the project must not exceed 2,000
• Provide complete documentation for all phases of
  the project
• Phases Problem Definition, System Design,
  Components Acquisition, Hardware/Software
  Development, System Integration, System Testing,
  System Optimization, Field Demonstration

Summary and Upcoming Plans

• SUMMARY
• Agreed upon and began implementing primary design
  plan
• Researched specific components antenna, solar
  panel charger, and battery
• Tested and configured the board
• UPCOMING PLANS
• Continue researching individual components
• Make a list of desired parts and submit to mentor
• Construct a prototype and begin testing
• Research secondary objectives (i.e. using DWAP to
  take over or disrupt enemy networks)
