Good for current needs, but may require upgrades sooner
The internet is crucial for companies, as it's used for everything from basic communication to complex data transfers and cloud-based applications. Business owners need to understand the factors contributing to internet speed; bandwidth is one of the most significant factors.
Bandwidth refers to the maximum amount of data transmitted over an internet connection in a given time. It's like a pipeline for digital information; a larger pipe allows more data to flow through at once. Bandwidth is measured in bits per second (bps), often expressed as megabits per second (Mbps) or gigabits per second (Gbps).
The amount of bandwidth available directly affects several aspects of internet performance:
Data Transfer Speeds: Higher bandwidth allows faster downloads and uploads of files, which is critical for businesses working with large amounts of data, such as multimedia files or complex databases.
Streaming Quality: Adequate bandwidth ensures smooth streaming of video content and online conferencing, which is essential for businesses that use these tools for communication and collaboration.
Cloud Application Performance: Many businesses utilize cloud-based services. Sufficient bandwidth is necessary for these applications to function optimally, preventing delays and disruptions in workflow.
In the following sections, we'll explore the distinction between bandwidth and speed, examine the roles of download and upload speeds, and provide guidance on optimizing bandwidth for improved internet performance.
Concept
What You Need to Know
Actionable Tip
Bandwidth
Think of it as the “data highway” – a wider highway (more bandwidth) means more data can flow simultaneously.
Choose an internet plan with enough bandwidth to support all your online activities.
Bandwidth vs. Speed
Bandwidth is the capacity of your connection, while speed is how quickly data travels. Both are important for a smooth online experience.
Don't just focus on Mbps! Consider latency and network congestion, too.
Download vs. Upload
Download speed is used to receive data (like loading websites), while upload speed is used to send data (like video calls).
If you upload a lot of data, look for an internet plan with symmetrical download/upload speeds.
Optimization
Many factors can affect internet performance, including network congestion, router settings, and the number of connected devices.
Check your internet speed regularly and troubleshoot any issues that arise. Upgrading your router can often make a big difference!
Bandwidth vs. Speed: Not Quite the Same Thing
While the terms “bandwidth” and “speed” are often used interchangeably, there's a subtle yet important distinction between them. Understanding this difference can help you make informed decisions about your internet service and optimize your online experience.
Think of it this way: bandwidth is the width of the highway, while speed is how fast cars can travel on that highway. A wider highway (higher bandwidth) can accommodate more cars (data) simultaneously, but the speed limit (speed) determines how quickly those cars can reach their destination.
Bandwidth: Measures the amount of data that can be transferred per second. It's the capacity of your internet connection.
Speed: Measures how quickly data is transferred from one point to another. It's influenced by various factors, including bandwidth, but also things like latency (delay) and network congestion.
To illustrate this further, imagine two internet connections:
Connection A: 100 Mbps bandwidth, but high latency and network congestion.
Connection B: 50 Mbps bandwidth but low latency and minimal congestion.
Even though Connection A has a higher bandwidth, Connection B might deliver data faster due to the lower latency and reduced congestion. This highlights why it's essential to consider both bandwidth and speed when evaluating internet service providers.
In practical terms, this means that a high-bandwidth connection doesn't automatically guarantee a fast internet experience. Factors like your internet service provider's infrastructure, network traffic, and even the quality of your modem and router can all affect your overall speed.
Download vs. Upload: Two Sides of the Same Bandwidth Coin
When browsing internet plans, you'll often see speeds advertised like this: “100 Mbps download / 10 Mbps upload.” This highlights another important aspect of bandwidth: it has two distinct components: download and upload.
Download speed is the rate at which data travels from the internet to your device. It's what dictates how quickly you can load web pages, stream movies, or download files.
Upload speed is the rate at which data travels from your device to the internet. It affects activities like sending emails, uploading videos to YouTube, or participating in video conferences.
Most internet service providers (ISPs) prioritize download speed over upload speed. This is because the average internet user spends significantly more time downloading data (browsing websites, watching videos) than uploading it. However, this doesn't mean upload speed is unimportant.
Here are some situations where upload speed becomes critical:
Video Conferencing and Live Streaming: Sending high-quality video requires substantial upload bandwidth. Slow upload speeds can lead to choppy video, lag, and dropped connections.
Cloud Storage and File Sharing: If your business frequently backs up data to the cloud or shares large files with clients or colleagues, a fast upload speed is essential for efficient workflows.
Online Gaming: For gamers, upload speed is crucial in responsive gameplay and avoiding lag, especially in fast-paced multiplayer games.
If your business relies heavily on any of these activities, choosing an internet plan with sufficient upload bandwidth is crucial. Some ISPs, particularly fiber optic providers, offer symmetrical plans with equal download and upload speeds, which can be a great option for businesses with high upload demands.
Factors That Influence Bandwidth: Beyond the Mbps
While your internet plan's advertised speed provides a baseline for your expected bandwidth, several other factors can influence your internet performance. Understanding these factors can help you troubleshoot connectivity issues and optimize your network for maximum efficiency.
1. Network Congestion
Like rush hour traffic can slow down cars on a highway, high internet traffic can lead to network congestion. This occurs when multiple users on the same network try to access and transmit data simultaneously, resulting in slower speeds and increased latency. This is especially common during peak usage times, such as evenings and weekends.
2. Internet Service Provider (ISP) Limitations
Your ISP's infrastructure and network capacity significantly influence your bandwidth. Some ISPs may have limitations in certain areas or during specific times, affecting overall speed. Your internet connection (cable, fiber optic, satellite) can also impact your bandwidth. Fiber optic connections, for example, generally offer higher bandwidth and more consistent speeds than cable.
3. Hardware and Software
The quality and configuration of your modem, router, and network cables can also affect your bandwidth. Outdated or malfunctioning equipment can create bottlenecks and slow down your connection. Similarly, outdated software or operating systems, viruses, and malware can also negatively impact your internet performance.
4. Number of Connected Devices
Each device connected to your network consumes a portion of your available bandwidth. As more devices connect and compete for resources, your device speeds may decrease. This is particularly noticeable in homes or offices with devices connected simultaneously, such as smartphones, laptops, smart TVs, and gaming consoles.
5. Website and Server Performance
Even with a high-bandwidth connection, the performance of the websites and servers you're accessing can affect your experience. A website with a slow server or limited bandwidth can lead to slow loading times, regardless of your internet speed.
By being aware of these factors, you can take steps to optimize your network and improve your internet performance. This may involve upgrading your hardware, optimizing your router settings, or switching to a different ISP with better infrastructure.
Optimizing Your Bandwidth for a Faster Internet Experience
Now that you understand the factors that can influence your bandwidth, it's time to take action to optimize your internet connection. Here are some practical tips you can implement:
1. Upgrade Your Hardware
Consider upgrading your modem and router to newer models with higher bandwidth speeds and advanced features. Ensure your equipment is compatible with your internet service provider's network technology.
2. Optimize Your Router Settings
Adjust your router's settings to prioritize bandwidth for specific devices or activities. You may also want to enable features like Quality of Service (QoS) to prioritize certain types of traffic, such as video streaming or online gaming.
3. Keep Your Software Updated
Update your operating system, web browsers, and other software regularly to ensure they are optimized for the latest internet technologies. Outdated software can sometimes hinder your connection speed.
4. Limit Unnecessary Background Processes
Close unnecessary programs and background processes that may be consuming bandwidth. This can free up resources for your primary activities, such as web browsing or video streaming.
5. Connect Directly to Your Modem or Router
If possible, avoid using Wi-Fi and connect your devices directly to your modem or router using Ethernet cables. This can eliminate interference from other Wi-Fi networks and improve your connection speed.
6. Use a Wired Ethernet Adapter
If you need Wi-Fi, consider using a wired Ethernet adapter to connect your device to your router. This can provide a more stable and faster connection than using Wi-Fi alone.
7. Avoid Peak Usage Times
Schedule your most bandwidth-intensive activities for off-peak hours when there's less network congestion.
8. Choose the Right Internet Plan
Select an internet plan that meets your specific needs and usage habits. When choosing a plan, consider factors like download and upload speeds, data caps, and pricing.
9. Contact Your ISP for Support
If you're experiencing persistent issues with your internet speed, don't hesitate to contact your internet service provider for assistance. They can help troubleshoot any problems and provide technical support.
Remember, optimizing your bandwidth is an ongoing process. Monitor your internet speed regularly and adjust your settings as needed to ensure the best possible performance.
Conclusion
Bandwidth is crucial in determining your internet speed and overall online experience. By understanding the different aspects of bandwidth and implementing the tips in this guide, you can optimize your connection and enjoy a faster, more reliable internet experience.

Think of your network as a highway, and Ethernet cables as the lanes on that highway. Like with a physical highway, wider lanes and better overall construction create a faster and smoother traffic flow. The same concept applies to your network – the cable you choose has a significant impact on your speed, reliability, and the overall performance of your network.
The 2025 reality: While older installations may still rely on Cat5e, any new network installation today will almost certainly use Cat6 as the baseline standard, with Cat6A becoming the go-to choice for high-performance and future-proof deployments.
When selecting an Ethernet cable, consider three fundamental factors:
Category (Speed): How fast do you want your lanes to be?
Jacket Type (Environment): Where will this “highway” be built?
Shielding (Protection): Do your lanes need extra protection from “hazards”?
Let's explore these aspects to ensure you choose the perfect Ethernet cable for your setup and our tested recommendations for each category.

The New Standard: Why Cat6 Dominates 2025 Installations
The networking industry has reached a tipping point where Cat6 has effectively replaced Cat5e as the baseline standard for new installations. Here's why this shift makes both technical and economic sense:
Economic Reality
The cost differential between Cat5e and Cat6 has virtually disappeared, often representing less than 10% additional material cost. When you factor in labor costs (which remain the same regardless of cable category), choosing Cat5e for new installations has become a false economy.
Performance Requirements
Modern networks demand more than the 1 Gbps ceiling of Cat5e:
Video conferencing and digital displays benefit from the additional bandwidth headroom
Cloud-based applications and large file transfers strain Cat5e networks
Future-Proofing Imperative
Installing Cat5e in 2025 is akin to installing yesterday's technology today. With internet service providers increasingly offering multi-gigabit residential plans and businesses adopting bandwidth-intensive applications, Cat6 provides essential future-proofing without significant additional investment.
Industry Adoption
Professional network installers report that 85% of new commercial installations now specify Cat6 or higher, with Cat6A becoming standard for enterprise environments and high-density applications.
Pro Insight: Even if your current internet plan is under 1 Gbps, Cat6 ensures your infrastructure won't become a bottleneck as services evolve. The investment in proper cabling pays dividends for 10-15 years.

Understanding Cat7: The Non-Standard That Confuses Buyers
Cat7 represents one of the most common sources of confusion in ethernet cable selection. Here's what you need to know:
Why Cat7 Isn't Recommended
TIA did not officially recognize categories 7 and 7A, which were generally only used outside the United States. While some manufacturers continue to market Cat7 cables, they fall into a regulatory gray area that creates unnecessary complications:
Connector Incompatibility: Cat7 was designed for GG45 and TERA connectors, not the standard RJ45 connectors used throughout the industry
No Official IEEE Recognition: Unlike Cat5e, Cat6, Cat6A, and Cat8, Cat7 never received official standardization
Market Redundancy: Cat6A provides equivalent performance with full standards compliance
The Marketing Problem
Many consumers encounter Cat7 cables marketed at attractive prices, often positioned between Cat6 and Cat6A. However, these cables typically use standard RJ45 connectors, negating any theoretical advantages of the Cat7 specification.
Our Recommendation
Skip Cat7 entirely. If you need performance beyond Cat6, invest in properly specified Cat6A cables that provide official standards compliance and guaranteed interoperability.
Jacket Types: Environment-Specific Requirements
The cable jacket serves as the first line of defense against environmental hazards. ANSI/TIA-568 defines structured cabling system standards for commercial buildings, including cable installation requirements and performance characteristics. Choosing the wrong jacket type can result in cable failure, code violations, or safety hazards.
