Large Market Opportunity
Juniper Research published a report which said the market for location-based services (think mobile check-in games like Foursquare, social networks like Loopt, location-enabled apps like Google Maps, etc.) will bring in revenues of more than $12.7 billion by 2014.
Frost & Sullivan estimates that mobile advertising alone will generate $2.4B by 2015.

Geo-location ResultsDeveloped portable, battery-operated proof of concept:
Dimensions: 3x4x2 inches
Operating frequencies: VHF (High-band)
Operating bandwidth: 5 MHz
In all tests TX and RX antennas heights were between 0.5 meter to 1.5 meters from the ground .
