Introduction
Topher White (son of Bebo White) is convinced that we/he could install the PingER software on the Android phone/OS. He literally has 100's of them that have been donated to his project. The delays will be very different. It will be fascinating to try and understand what parameters determine the delays and losses, quantify the information and compare with wired MAs. Initially the phones would be stationary and use WiFi (thus eliminating roving effects, and cell phone coverage). The power use and availability of smartphones could make it a very interesting platform for PingER.
Power
Smart phones are very energy efficient because they are designed to run on a battery for a long period of time. For a smartphone battery with 1650mAh and a voltage of 3.7V (typical cell phone battery voltage 3-5V) the Wattage for an 8 hour talk time on 3G is 0.76 W.
Assuming the smartphone is charged once a day from 0% to 100% a Galaxy SIII: consumed 12.3 watt-hours to charge, taking 2 hours and 26 minutes, the maximum wattage was 6.6 watts, with an average of approximately 5.0 W.
According to measurements from Lawrence Berkeley National Laboratory, the average cell phone draws 3.68 watts of power from the outlet while it's charging and 2.24 watts when charged.
One can buy off the shelf solar cell phone chargers, for example the SolPro that in direct sunlight can re-charge its battery (a Lithium-Polymer battery with safety circuitry and capacity of 4500mAh enough to keep a smartphone going all day) in 4.5 hours.
