What are the uplink and downlink speeds of 300M broadband?

The uplink and downlink rates of 300M broadband are 90M and 300M respectively, which means the uplink is 90M and the downlink is 300M; the broadband rate refers to the maximum theoretical rate that can be achieved technically, which is generally the upload and download speed. , the higher the rate, the faster the upload and download.

What are the uplink and downlink speeds of 300M broadband?

The uplink and downlink speeds of 300M broadband are 90M uplink and 300M downlink.

Broadband speed refers to the maximum theoretical speed value that can be achieved technically, which is generally the speed of uploading and downloading. The higher the speed, the faster the uploading and downloading.

The broadband service rate applied by the user is the maximum theoretical rate value. Since the user's Internet access is also affected by the configuration of the user's computer software and hardware, the address of the website being browsed, the bandwidth of the peer website, etc., therefore, the user The speed when surfing the Internet is usually lower than the theoretical speed value.

Theoretically, 2M, that is, 2Mb/s, the theoretical broadband rate is 256KB/s. The actual rate is approximately 103--200kB/s. (The reason is affected by many factors such as user computer performance, network equipment quality, resource usage, network peak periods, website service capabilities, line attenuation, signal attenuation, etc.). 4M, that is, the theoretical rate of 4Mb/s broadband is 512KB/s, and the actual rate is approximately 200---440kB/s.

ADSL uses two different frequency bands to transmit uplink and downlink channels respectively, and its downlink can reach 8Mbit/s and uplink can reach 640Kbit/s. The download rate that operators can provide to individual users is 512Kbit/s. It can also dynamically adjust the user's access speed based on the quality of the phone line and the distance of the transmission distance, which can fully meet the requirements of multimedia video applications.

Basic standard

The speed of 512k users reaching the speed test website is greater than 40KByte/s, that is, 320Kbps, which is normal;

1M users The speed when reaching the speed test website is greater than 80KByte/s, that is, 640Kbps, which is normal;

The speed when users with more than 2M users reach the speed test website is greater than 160KByte/s, that is, when it is 1280Kbps, it is normal;

The speed for users with more than 4M users to reach the speed test website is greater than 320KByte/s, that is, 2560Kbps is normal.
