Actual exam question for CWNP's CWISA-103 exam
Question #: 6
Topic #: 2
[All CWISA-103 Questions]

Which one of the following location tracking technologies is most energy efficient in typical implementations?

Show Suggested Answer Hide Answer
Suggested Answer: A

BLE Beacon Power Efficiency:Bluetooth Low Energy (BLE) beacons are designed for low power consumption.Their primary function is to periodically broadcast short data packets (advertising their presence).

Other Technologies:

Cellular:More power-hungry due to long-range communication and complex protocols.

GPS:Power intensive,especially when actively tracking location.

Wi-Fi:

GPS? More like G-Waste-of-Battery if you ask me. That thing sucks the life out of your device.
