What EarthLink Internet Information Guide Contains

The EarthLink Internet Information Guide is a free educational resource that explains how internet service works and what options may be available to different households. The guide does not determine who qualifies for any programs or provide internet service itself. Instead, it presents factual information about broadband technology, how different types of internet connections function, and general details about various service providers operating in different regions.

The guide covers foundational topics about internet connectivity. It explains the difference between broadband and standard internet speeds, describing how data travels through different types of infrastructure. The resource includes information about satellite internet, which can reach rural areas where cable or fiber may not be available. It also describes fixed wireless access, a newer technology that uses radio signals to deliver internet to homes and businesses.

One section of the guide focuses on understanding internet speeds and what they mean for daily use. The guide explains bandwidth, measured in megabits per second (Mbps), and describes what different speed levels support. For example, streaming video typically requires 5-25 Mbps depending on video quality, while video conferencing usually needs 2.5-4 Mbps. The guide helps readers understand technical specifications in plain language so they can evaluate whether different service options match their household needs.

The guide also addresses internet costs and pricing structures. It explains how providers determine their rates, what factors affect monthly bills, and what hidden fees readers should watch for when comparing services. The resource teaches readers to read service agreements and understand contract terms before making decisions. This information helps households compare options more effectively.

Practical Takeaway: Before contacting any internet provider, review the guide's section on service types and speeds. This preparation helps you ask informed questions and understand what providers are offering, making it easier to compare different services in your area.

Understanding Different Types of Internet Connections

The guide provides detailed information about the major types of internet connections available across the United States. Each technology works differently, reaches different geographic areas, and offers varying speeds and reliability. Understanding these differences helps readers recognize which options may serve their location.

Cable internet uses the same infrastructure that delivers television signals. The guide explains that cable networks were built throughout many suburban and urban areas beginning in the 1980s. According to the FCC's 2023 broadband deployment report, cable internet serves approximately 60% of the U.S. population. The guide describes how cable works: data travels through coaxial cables to neighborhoods, then into individual homes. Cable typically offers speeds between 25-1,000 Mbps, though actual speeds depend on local network capacity and the plan a customer purchases. The guide notes that cable speeds can slow during peak hours when many users are online simultaneously in the same area.

Fiber optic internet represents newer technology that transmits data using light pulses through thin glass or plastic strands. The guide explains that fiber is faster and more reliable than cable because light doesn't degrade over distance the same way electrical signals do. Fiber speeds commonly range from 100-1,000 Mbps or higher. The guide includes information about fiber's growing availability. As of 2024, fiber passed approximately 45 million U.S. addresses, according to industry tracking data. However, fiber installation requires significant infrastructure investment, so it remains concentrated in urban areas and some suburbs.

Satellite internet works by transmitting signals to and from satellites orbiting Earth. The guide explains this technology's advantages for rural locations where cable and fiber don't reach. Traditional satellite internet suffered from high latency—the delay between sending and receiving data—which made real-time activities like video calls difficult. The guide describes newer low-earth orbit satellites that significantly reduce this delay. Starlink, for example, uses satellites orbiting 340 miles above Earth compared to traditional satellites at 22,000 miles, resulting in latency under 50 milliseconds in many cases. The guide notes that satellite speeds have improved to 50-200 Mbps for many users, making it viable for typical household tasks.

Fixed wireless access uses radio towers to transmit internet signals to receivers mounted on homes or buildings. The guide explains that this technology requires line-of-sight to the transmitter tower. Many wireless providers are expanding fixed wireless networks in areas where laying cable or fiber would be too expensive. The guide includes information that T-Mobile, Verizon, and other carriers now offer home internet via fixed wireless. Speeds typically range from 50-300 Mbps depending on network load and signal strength.

Practical Takeaway: Identify which connection types currently serve your area by checking provider websites or using broadband search tools. The guide's descriptions of each technology help you understand what's technically possible in your location, then research which providers offer each type in your specific neighborhood.

Speed, Bandwidth, and What You Actually Need

Internet speeds confuse many consumers because marketing materials use technical language and advertise maximum speeds that real users rarely achieve. The EarthLink guide translates these specifications into practical information about what different speeds mean for common activities. This knowledge helps readers understand whether a service option truly meets their needs or if they should seek faster alternatives.

The guide defines Mbps (megabits per second) as the standard measurement of download speed—how fast information travels from the internet to your device. Upload speed, measured the same way, describes data going from your device to the internet. These are different because home internet service asymmetric, meaning download speed is typically much faster. The guide explains that 25 Mbps download was long considered the FCC's minimum for broadband adequacy, though many experts now recommend higher speeds.

The guide provides specific examples of how much bandwidth different activities consume. Checking email or browsing websites uses minimal bandwidth, typically under 1 Mbps. Streaming music on Spotify requires around 1-2 Mbps for standard quality. Streaming video demands significantly more: Netflix recommends 5.5 Mbps for HD quality (1080p) and 25 Mbps for 4K quality. YouTube's recommended speeds range from 1 Mbps for standard definition to 35 Mbps for 4K. Video conferencing through Zoom needs 2.5 Mbps for one-on-one calls but scales up for group meetings. Online gaming typically uses only 1-5 Mbps for the actual game, though the connection's stability and latency matter more than speed.

The guide addresses simultaneous use scenarios because most households involve multiple people online at once. If two household members are each streaming HD video while a third person is video conferencing, the total demand is roughly 5.5 + 5.5 + 2.5 = 13.5 Mbps. A 50 Mbps connection can handle this comfortably. However, if one person is downloading a large file at the same time, actual speeds may be slower because bandwidth is shared. The guide recommends accounting for future needs and occasional peak usage when selecting a service.

The guide explains latency—the time delay between sending a request and receiving a response—separately from speed. Latency matters more than speed for gaming, video conferencing, and real-time applications. Cable and fiber typically offer low latency below 30 milliseconds. Satellite internet historically suffered high latency exceeding 500 milliseconds, though newer systems reduce this substantially. The guide notes that latency is not always visible in speed test results but significantly affects user experience in time-sensitive applications.

Practical Takeaway: Make a list of your household's typical internet activities and count how many happen simultaneously. Cross-reference this with the guide's bandwidth requirements to understand what speed tier makes sense for your situation. You'll have a concrete number to use when comparing provider options.

Evaluating Internet Service Providers and Plans

The guide provides a framework for comparing different internet providers objectively. Rather than recommending specific companies, the guide teaches readers what questions to ask and what factors matter when evaluating their options. This approach helps readers make decisions based on their particular location, budget, and needs.

The guide explains that internet service pricing varies dramatically by geography. In competitive markets with multiple providers, prices tend to be lower and promotions more common. In areas served by a single provider, prices may be significantly higher because customers have no alternatives. According to BroadbandNow data, the average American broadband bill is approximately $65 per month, but this ranges from under $40 in competitive areas to over $100 in some locations with limited options. The guide recommends getting quotes from all available providers in your specific neighborhood, as national averages don't reflect local market conditions.
