What is Wireless Throughput?
Wireless throughput is a measure of the actual data transfer speed that can be achieved over a wireless network. Unlike theoretical maximum speeds often advertised by internet service providers or wireless equipment manufacturers, throughput reflects the real-world performance experienced by users.
To put it simply, throughput is the amount of data successfully transmitted through a network in a given time frame, usually measured in bits per second (bps), kilobits per second (kbps), megabits per second (Mbps), or gigabits per second (Gbps).
The Difference Between Throughput and Bandwidth
While the terms throughput and bandwidth are often mistakenly used interchangeably, they refer to different concepts within network performance.
- Bandwidth can be likened to a highway’s width, representing the maximum amount of data that can be sent over a network at any given time. This measurement is a theoretical limit and does not reflect the actual performance of the network.
- Throughput, on the other hand, is akin to the number of cars that actually make it through a toll booth. It accounts for various factors such as network congestion, signal strength, interference, and protocols in use, resulting in a more realistic assessment of performance.
Understanding this distinction is essential for identifying why you may not be receiving the internet speeds promised by your service provider.
