dsl
cellular wan
long-range fixed wireless
satellite

Explanation:

Analyze the requirements of the prompt

The question asks for a cost-effective internet connectivity solution specifically suited for travelers (mobile users), as opposed to stationary connections like cable and fiber-optic modems.

Evaluate the given options

• DSL (Digital Subscriber Line): This is a wired, stationary technology that relies on physical telephone lines. It is not suitable for travelers.
• Cellular WAN (Wide Area Network): This technology uses cellular networks (like 3G, 4G LTE, or 5G) to provide internet access. It is highly mobile, widely available, and cost-effective for travelers using smartphones, hotspots, or cellular-enabled laptops.
• Long-range fixed wireless: This is a stationary wireless technology that requires a line-of-sight dish or antenna mounted at a fixed location. It is not portable for travelers.
• Satellite: While satellite can provide coverage for travelers (e.g., in remote areas), it typically requires expensive, bulky specialized equipment (like a satellite dish) and has high subscription costs, making it less cost-effective and convenient for general travelers compared to cellular options.

Determine the best fit

Cellular WAN is the most practical, portable, and cost-effective solution for travelers to maintain internet connectivity on the go.

Answer:

• DSL
• Cellular WAN (Correct answer)
• Long-range fixed wireless
• Satellite
