According to Paessler, monitoring and bandwidth management are a useful way to better understand and exploit your WiFi and identify potential problems.
For this reason, the company reveals how to get the most out of its WiFi network thanks to a monitoring system as its PRTG Network Monitor can be.
The term “bandwidth” is commonly used in the world of “IT” to refer to frequency ranges.
Signal transmitters, such as cables, have certain frequency bands on which data is transmitted.
The greater the bandwidth, the greater the number of data that can be transmitted simultaneously: the bandwidth is therefore used as a synonym for the data transfer rate.
The bandwidth is therefore the amount of data that is transferred from one place to another at a given time, usually a second. The unit of measurement for the networks is in fact the bit per second (bps), but today’s networks are generally referred to as megabit per second or gigabit per second, or one billion bits per second.
Paessler considers bandwidth management as one of the various ways to have more control over the WiFi network.
With bandwidth monitoring, you don’t actively manage bandwidth but simply observe the amount of WiFi bandwidth consumed by devices and applications.
Once the amount of bandwidth used has been verified, it is possible to switch to the actual WiFi bandwidth management that includes the bandwidth distribution to all devices in the network.
A variety of software is available for management, or you can also adjust the consumption of individual bandwidth of devices such as routers or switches in your device settings.
These settings may vary depending on the manufacturer.
As Paessler points out, the last step is bandwidth control; you can measure, control, limit and customize the bandwidth and data speed distribution at any time.
Some sensors give a more precise idea of how to manage bandwidth with a monitoring solution such as PRTG Network Monitor: The SNMP traffic sensor measures bandwidth consumption.
You can use it to determine the speed at which data flows through the network. Cisco and Juniper devices use Flow technologies and PRTG comes with a set of pre-configured flow sensors for these manufacturers.
These sensors also allow filtering based on IP addresses, protocols, data types and programs.
The PRTG Packet Sniffer sensor filters data traffic based on IP addresses, protocols, data types, programs, and more. It is possible to use the data collected by this sensor to perform a detailed traffic analysis.
