Difficulty: EasyMobile Device Wireless and Network Connectivity

A technician is explaining mobile device networking options to a end user. Match each mobile connectivity feature on the left with its corresponding technical function on the right.

  • Airplane ModeDisables all cellular, Wi-Fi, and Bluetooth radio transceivers simultaneously.
  • Mobile HotspotShares the mobile device's cellular data connection with external client devices over Wi-Fi.
  • Bluetooth PairingEstablishes an authenticated, short-range Personal Area Network (PAN) connection between two devices.
  • Wi-Fi CallingRoutes cellular voice calls and SMS text messages over a local 802.11 wireless network.

Answer

Airplane Mode disables all wireless transceivers; Mobile Hotspot shares cellular internet over Wi-Fi; Bluetooth Pairing links short-range devices via authentication; Wi-Fi Calling routes calls over an 802.11 network.
Each feature directly aligns with its core functionality: Airplane Mode turns off all wireless radios; Mobile Hotspot shares a cellular internet connection via Wi-Fi; Bluetooth Pairing secures a short-range Personal Area Network; and Wi-Fi Calling carries carrier voice traffic over an 802.11 Wi-Fi connection.

Step-by-Step Solution

1
Identify the function of Airplane Mode.
It toggles off all radio transceivers including cellular, Wi-Fi, and Bluetooth.
Airplane mode is designed to quickly disable all RF signals.
2
Identify the function of Mobile Hotspot.
It broadcasts a local Wi-Fi network that routes client traffic over the device's cellular data plan.
Hotspot enables internet sharing with external devices such as laptops or tablets.
3
Identify the function of Bluetooth Pairing.
It exchanges authentication keys to connect two devices into a Personal Area Network (PAN).
Pairing enables wireless peripheral connectivity like headsets or keyboards.
4
Identify the function of Wi-Fi Calling.
It transmits carrier voice packets over a local 802.11 wireless network.
Wi-Fi calling bridges phone service using IP networking when cell towers are unreachable.
