Why each option
Bluetooth pairing is the standard short-range wireless protocol used to connect devices like GPS units and smartphones without requiring cables or network infrastructure.
A data link cable requires a physical wired connection, which is inconvenient and not practical for mobile device-to-device communication.
A wireless access point provides Wi-Fi infrastructure connectivity to a network, not direct device-to-device communication between a GPS and a smartphone.
Bluetooth is a short-range, low-power wireless standard specifically designed for personal area network (PAN) device-to-device communication, such as connecting a GPS receiver to a smartphone. Pairing establishes a secure, authenticated link between the two devices for data exchange.
Infrared communication is a legacy, line-of-sight technology with very short range and low throughput, largely obsolete for this type of use case.
