Tips & Best Practices
-
Understand the context of each unit's use within legacy and modern networks.
-
Use the conversion primarily for comparison and planning, not precise performance metrics.
-
Recognize that real-world modem speeds often vary below theoretical maximums.
-
Apply conversions alongside knowledge of network protocols and overhead.
Limitations
-
Conversion rates reflect theoretical data transfer speeds without real-world noise or interference.
-
Does not account for modem upstream speed restrictions or actual performance variances.
-
Practical throughput may be lower due to protocol overhead and line conditions.
Frequently Asked Questions
