History
1995 AUSD began using wireless for its Wide Area Network
1997 Model Technology Program tested for laptop carts
1998 AUSD Implements wireless laptops as standard for access
1999 AUSD switches to 11MBS 802.11 standard
Wireless Technology:
How it Works
Infrared
Microwave
Satellite
Spread Spectrum
Wireless Technology: Spread Spectrum
Signal uses the 9GHz radio band
Radio signal literally spreads across the radio frequency spectrum
Spread Spectrum goes around obstructions
Versatile and powerful
Unlicensed
Original Use in AUSD: WAN
Looking for low cost, high speed WAN to connect schools
Spread Spectrum offered distances up to 3 miles
Erected 90 foot tower with antennas on 2 story building at DO
School has reciprocal mast and antenna
Provided 2MB throughput to school site vs. 1.5MB T1s
Slide 7
AUSD Wireless WAN
Proved effective for 3 years
Low cost, somewhat high maintenance
Degraded as number of computers passed 3,000 because of Bridging not routing
Still a good option for schools starting networking
Abandoned in 1999 for multiple T1s and routers to each site
Original Laptop Concept
More access in classrooms vs. labs
Every classroom had two to five computers on side of classroom
Needed more access at times
Did not want more labs…keep it in the classroom...
Roll the lab into the classroom
Original Laptop Concept
Flexible classroom arrangements
Encourage cooperative groupings/projects
Access away from the “walls”
Desks in clusters not rows
Anytime, Anywhere Access
Laptop Cart v1.0
A rolling cart with electrical
Network hub to connect to classroom network connection
Every classroom has a fiber optic port and CAT5 hub
A network laser printer
6 to 10 laptops connected via cables to the hub…
The Result:
Spaghetti City
Model Technology Program
Two carts awarded to two teams of 4 teachers
8 Laptops with wires
Concept great!
Execution…
The Results: Fixed Laptop Workstations
Teachers created individual workspaces
Special tables, counters to control wires
Found individuals using the computers not groups
The “rolling lab” never rolled….
Stayed where it was set up because of time required to assemble
The Laptop Cart v2.0: Wireless
Retrofitted existing carts mid-year
Switched to wireless network cards
Installed access points
Results were dramatic…
The Results, v2.0
Groups of students using laptops in clusters away from walls
Slide 16
The Results, v2.0
Cart shared between team members’ rooms…
The Results, v2.0
Students used laptops for quality work…and for more time
Slide 19
Anytime, Anywhere...
Next step was to move away from the carts
What happens when a whole group of students has access to a wireless laptop 24 hours a day?
What happens when a child decides “when,where and how” to use technology in their education?
1999 Model Technology Program
Outfitted a 6th/7th grade “class” with 32 wireless laptops
Provided network access and printing points throughout school
Allowed students to keep them 7/24 with a small monthly fee
The results….
Slide 22
1999 Model Technology Program
Increased research in all classes
Higher quality products
Higher quality and quantity of writing
Students engaged in high quality work
But...
1999 AA Beyond Wireless
Grade 5 class 7/24 access to NEC MobilePros palm top computers
2/3 Class 7/24 access to AlphaSmart word processors
Results have been amazing…especially Grades 2/3 for writing
The Wireless Cart
Dell Pentium II Laptop Computers (8 to 10 per cart), $1,800 each
Lucent Network Interface Cards, 1 per laptop, $175 each
Lucent WavePoint Access Point, 1 per cart or about every 50 yards, $995 (overlapping vs. Apple’s new version)
Antenna extension, $95.00
The Wireless Cart
Network Printer $1,200 to $1,500
Bretford Notebook Cart w/ Electrical $400
8 port 10 base-T Hub $80
Velcro...

What we have...
Arcadia High School:
24 Laptop Carts with 10 laptops per cart
Foothills Middle School:
3 Laptop Carts with 8 laptops per cart
32 Wireless laptops for AAA Model Tech
Camino Grove Elementary School:
2 Laptop Carts with 10 laptops per cart
Holly Avenue Elementary School:
1 Laptop Cart with 10 laptops per cart
More on the way….
Conclusions
Versatile method for creative uses of technology in the classroom
Method for removing many of the traditional barriers for using technology
Helps redefine classroom organization and the quality of work the physical environment often dictates
