📚 Broadband Glossary — Key Terms Explained
- Mbps
- Megabits per second — the standard unit for measuring internet speed. 100 Mbps handles HD streaming on 3–4 devices.
- Gbps
- Gigabits per second — 1 Gbps = 1,000 Mbps. Gig-speed plans are ideal for large households or home offices with heavy upload needs.
- Fiber Internet
- Uses light pulses through glass cables. The fastest, most reliable technology available — symmetric upload and download speeds.
- Cable Internet
- Delivered over coaxial TV lines. Fast downloads, widely available — upload speeds are slower than fiber.
- DSL
- Digital Subscriber Line — uses existing phone lines. Reliable and widely available but slower than fiber/cable.
- 5G Home Internet
- Fixed wireless access using 5G towers. No line required — quick self-install. Speeds vary by distance from tower.
- Satellite Internet
- Delivered from satellites in orbit. Available almost everywhere — higher latency than ground-based options.
- Latency
- The delay in ms before data transfer begins. Low latency (<20ms) is critical for gaming and video calls; high latency (>100ms) causes lag.
- Bandwidth
- The maximum data capacity of your connection. Higher bandwidth = more devices streaming simultaneously without slowdowns.
- Data Cap
- A monthly limit on how much data you can use. Exceeding it may slow your speeds or result in overage charges.
- Symmetric Speeds
- When upload and download speeds are equal. Only fiber typically offers symmetric speeds — important for video calls and cloud backup.
- ISP
- Internet Service Provider — the company that sells your internet connection (e.g., Xfinity, AT&T, Spectrum).
