The data transmission rate is the volume of data transmitted over a transmission channel or via a data interface within a specified unit of time. The units used for this are baud or bits/s.

CAN FD : An Overview. A standard CAN network is limited to 1 MBit/s, with a maximum payload of 8 bytes per frame. CAN FD increases the effective data-rate by allowing longer data fields – up to 64 bytes per frame – without changing the CAN physical layer.

For example, if bandwidth is 100 Mbps but data rate is 50 Mbps, it means maximum 100 Mb data can be transferred but channel is transmitting only 50 Mb data per second. It is the potential of the data that is to be transferred in a specific period of time.

Plug the amount of data (A) and transfer time (T) to solve for the rate, or speed (S), into the equation S = A ÷ T. For example, you might have transferred 25 MB in 2 minutes. First, convert 2 minutes to seconds by multiplying 2 by 60, which is 120. So, S = 25 MB ÷ 120 seconds.

10-25Mbps: Moderate HD streaming, online gaming and downloading with a moderate number of connected devices. 25-40Mbps: Heavy HD streaming, online gaming and downloading with a lot of connected devices. 40+Mbps: Hardcore streaming, gaming, and downloading with an extreme number of connected devices.

To understand how much capacity you need, you must calculate the maximum number of users who might be using the network connection simultaneously and multiply that number times the bandwidth capacity required by each application.

Bandwidth is measured as the amount of data that can be transferred from one point to another within a network in a specific amount of time. Typically, bandwidth is expressed as a bitrate and measured in bits per second (bps).

Higher bandwidth is better. Many people think bandwidth is just a fancy word for internet speed. Your actual bandwidth will often be less than your maximum bandwidth because of network congestion and other external factors. If you want to see how fast your internet connection is now, use a speed test.

These are usually the same but not always. Definition: Speed is bit rate of the circuit while bandwidth is the amount of “speed” available for use. The bandwidth is the sum of the total connections but the speed is determined by the physical network connection.

Bandwidth describes the maximum data transfer rate of a network or Internet connection. For example, a gigabit Ethernet connection has a bandwidth of 1,000 Mbps (125 megabytes per second). An Internet connection via cable modem may provide 25 Mbps of bandwidth.

Bandwidth comparison – 2.4 GHz vs. 5 GHz signal

In most cases you should use 2.4 GHz to optimize for distance and 5 GHz to optimize for speed. However, there is a tradeoff between increased performance and range of coverage. 5 GHz is faster.

There are 20MHz, 40MHz, and 80MHz of channel bandwidth, and for a 2.4GHz frequency, 20MHz bandwidth would be the most beneficial.

Setting the channel width to 40 MHz network will allow you to use 2/3 of the entire Wi-Fi band. Thus having a higher chance of overlapping and interfering with other wireless networks. Meanwhile, if you set the channel width to 20 MHz, the network will only overlap with the two channels before and after that frequency.

Wi-Fi 6E Channelization The 802.11ax standard also defines channel allocations for the 6 GHz band. This allocation determines the center frequencies for 20 MHz, 40 MHz, 80 MHz and 160 MHz channels.
