ITPEC FE Subject A April 2026 Question 27
In telecommunication, which of the following is a standard for wireless broadband communication for mobile devices and data terminals?
Explanation
LTE — the cellular standard for wireless broadband to mobile phones and data terminals.
LTE (Long Term Evolution), standardised by 3GPP, carries high-speed data over a mobile operator's licensed spectrum across a wide area, and a device stays connected as it moves from one base station to the next. It is the basis of 4G mobile networks.
Answer (b)
Why not others:
- •(a) IEEE 802.11 — wireless LAN (Wi-Fi): broadband, but only within range of an access point, not a mobile telecommunication network
- •(c) NFC — near field communication over a few centimetres, used for contactless payment and pairing
- •(d) UWB — ultra-wideband, short-range radio used mainly for precise positioning and short links
Key rule: Place wireless standards by range: NFC covers centimetres, UWB and Bluetooth metres, Wi-Fi a building, and LTE or 5G a whole mobile network.
