A mobile systems technician is documenting wireless connectivity features and security configurations for enterprise smartphones. Match each mobile network feature on the left with its corresponding technical function on the right.
- Near Field Communication (NFC)Very short-range wireless communication operating at 13.56 MHz used for contactless payments and peer-to-peer data transfers within 4 cm.
- Mobile Hotspot / TetheringFeature enabling a smartphone to share its active cellular internet connection with nearby client devices over Wi-Fi or USB.
- Bluetooth PairingAuthentication procedure establishing a temporary personal area network (PAN) link between two devices using a shared passkey.
- Mobile VPNEncrypted networking connection that secures mobile data traffic over untrusted public Wi-Fi or cellular connections.
Answer
Near Field Communication (NFC) matches the short-range 13.56 MHz contactless payment capability. Mobile Hotspot / Tethering matches sharing cellular connectivity with surrounding client devices. Bluetooth Pairing matches establishing an authenticated PAN connection using a shared passkey. Mobile VPN matches providing an encrypted network tunnel over untrusted wireless links.
Each wireless technology corresponds directly to its standardized communication scope and role: Near Field Communication (NFC) provides 13.56 MHz short-range contactless interactions; Mobile Hotspot converts cellular data connections into local internet access points; Bluetooth Pairing connects local devices securely within a personal area network; and a Mobile VPN secures network transport via encrypted tunnels across public access networks.
