Segan said the problem lies in the antenna and transmission power. To reach a satellite, you need a larger antenna and stronger transmitter than what is typically found in an iPhone.
Most cell phones transmit at around four milliwatts, he explained.
Meanwhile, a spot satellite communicator—a device that can ping a rescue team from the woods—transmits at 400 milliwatts, and a Garmin satellite phone transmits at 1600.
Bottom line: “Transmitting to the satellites takes a big antenna, and I don’t know where you’d put that in an iPhone body,” Segan said.—JM
