| Explanation & Hint:
The type of wireless network that uses low powered transmitters for a short-range network, usually spanning 20 to 30 feet (6 to 9 meters), is a Wireless Personal-Area Network (WPAN). Here’s a brief overview:
- Wireless Personal-Area Network (WPAN): WPANs are designed for very short-range communications, typically within the range of a person’s immediate area (about 6 to 9 meters). Technologies like Bluetooth and ZigBee are common examples of WPANs, used for connecting devices such as smartphones, headsets, and wearable devices.
- Wireless Local-Area Network (WLAN): WLANs, like those using Wi-Fi technology, are designed for slightly larger areas such as homes, offices, or buildings. They typically cover a range larger than WPANs, often up to 100 meters.
- Wireless Metropolitan-Area Network (WMAN): WMANs are intended to cover large urban areas, like cities or metropolitan regions, much larger than the range of a WPAN.
- Wireless Wide-Area Network (WWAN): WWANs cover very large geographic areas, often spanning cities, regions, or even countries. They use cellular network technologies and have a much broader range than WPANs.
In summary, for a network with a short range of about 20 to 30 feet, the suitable type is a Wireless Personal-Area Network (WPAN). |
