Getting Use Cases Right• Iridium Satellite network launched
November 1, 1998
• Use Case: Wireless phone calls from remote location A to remote location B
• The company went into bankruptcy in nine months after launch, on August 13, 1999
• Bankruptcy filling cited "difficulty gaining subscribers"

Prohibitively costly $500+/pcs
Existing senosr monitoring solutions
Bulky solar panel powered
Do not scale to ~ 2-3 spots/ha monitoring
Proprietary / not universal designed by sensor vendors for own model range

Precision Agriculture Data Logger
Development of soil water balance model based on crop type and data from soil moisture sensors
Technical• Universal (any sensor)• Long range (20km)• Compact & Easy to
Connect: fits in the palm of hand, IP66, no cable glands
All inputs for photosynthesis modeling
• Soil moisture & temp.• Air humidity & temp.• Solar radiationKey objectives
• save hundreds of pounds per hectare on irrigation• early yield prediction and management

Data Analytics Prize: 28 bays at Finsbury Square, London
• Average Stay Duration – 72 min
• Average Bay Utilisation - 54%
• Total Value of Stays £5K/week
• More than 100 overstays per week

Getting Technology Right• The handsets could not operate as
promoted until the entire constellation of satellites was in place
• Reception indoors was difficult and the bulkiness and expense of the hand held devices when compared to terrestrial cellular mobile phones discouraged adoption
