Final answer:
The order of technologies in terms of coverage, from smallest to largest, is Bluetooth, WLAN, 4G, and 5G.
Step-by-step explanation:
The order of the given technologies in terms of their coverage area from smallest to largest is:
- Bluetooth
- WLAN
- 4G
- 5G
Bluetooth has the smallest coverage area as it is designed for short-range communication between nearby devices. WLAN (Wireless Local Area Network) has a larger coverage area than Bluetooth but is still limited to a specific area like a home or office. 4G (Fourth Generation) cellular networks have a wider coverage area than WLAN and can provide connectivity over large geographic regions. Finally, 5G (Fifth Generation) networks have the largest coverage area, as they are designed to provide high-speed wireless connectivity across cities and countries.
