The main difference lies in the connection method:

  • Optimum Internet typically uses a wired connection (either traditional cable or, increasingly, fiber-optic lines) run directly to your home. 
  • 5G Internet uses Fixed Wireless Access (FWA), receiving an internet signal wirelessly from a nearby cellular tower, similar to a mobile phone signal, through a gateway device in your home.
Feature Optimum (Cable/Fiber) 5G Internet (Fixed Wireless)
Connection TypeWired (coaxial cable or fiber optic)Wireless (cellular towers)
Reliability

Generally more reliable and less affected by congestion or weather, especially fiber.

Can be less reliable and prone to speed dips due to network congestion, distance from the tower, and physical obstructions.
SpeedOptimum offers much faster speeds and more consistent performance.Speeds are generally slower than fiber and can fluctuate based on tower traffic and signal strength.
Latency (Lag)Generally lower latency, which is better for POS systems and video conferencing.Generally higher latency and more susceptible to lag.

Optimum Internet plans have unlimited data and do not have hard data caps that would result in overage fees. This means you don’t need to worry about data limits or speed throttling based on typical usage.

5G Internet is less reliable for tasks that require low latency (sales transactions) or consistent speeds (like large file transfers or high-quality video conferencing, especially with multiple simultaneous users) due to potential congestion and signal fluctuation.

For the most stable and consistent experience crucial for professional work, a wired connection like Optimum Business Internet is typically the more dependable choice.

This is a comparison of a dedicated wired connection versus a shared wireless one:

  • Fiber Internet uses light signals sent through glass strands (fiber-optic cables) run directly to your home, offering the fastest available speeds (often symmetrical: same upload and download speeds), lowest latency, and highest reliability.
  • 5G Internet is a wireless service delivered via radio waves from a cellular tower. Speeds are generally slower, can vary based on factors like distance/obstructions, and upload speeds are typically much slower than download speeds.

Yes, weather can affect 5G internet performance.

5G uses radio waves, which can be weakened or disrupted by environmental factors. Heavy rain, dense snow, or even thick fog can interfere with the signal traveling between the cell tower and your home, potentially causing reduced speeds or intermittent service drops. Wired connections like fiber are much more resilient to these types of weather-related interferences.
