How many megabytes of broadband is 30mb/s?

30mb/s is about 240M broadband, and the conversion formula is "30MB/Sx8=240M"; usually the file size in megabytes refers to 4MByte; byte (Byte) is used in computer information technology for measurement A unit of measurement of storage capacity that also represents data types and language characters in some computer programming languages.

How many megabytes of broadband is 30mb/s?

30MB/Sx8=240M, equivalent to 240M broadband.

The unit used by operators to calculate broadband is Mb/s, while the unit used by software in computers and mobile phones to calculate broadband download speed is: MB/s. Among them, 1B=8b, that is, 1MB=8Mb; then, 30mb/s times 8=240MB. This is just a theoretical lower bandwidth megabyte. In actual use, due to the influence of routers, network cables and other equipment, the download speed will have an error of about 1M-2M.

Generally speaking, the file size in megabytes refers to 4MByte. Byte (Byte) is a unit of measurement used by computer information technology to measure storage capacity. It also represents data types and languages ​​​​in some computer programming languages. character.

The 2, 4, and 8 megabits in broadband network speeds usually refer to 2, 4, and 8Mbps. Mbps=Mbit/s is megabits per second (abbreviation of Million bits per second).bps (bits persecond), That is, bit rate, bits/second, bits/second, bits transmitted per second, common units of data transfer rate.

The conversion relationship between bytes and bits is as follows: Byte=8bit1KByte=1024Byte1M=1024KByte. Therefore, the commonly mentioned 4MByte download speed, converted to broadband speed is 4MByte*8=32Mbps/second.

1. 100M optical modem: WAN port transmission is 155M, but the operator limits it to 100M, LAN port is 100M, but performance determines the transmission speed to be about 90Mbps. The physical transmission bottleneck of optical modem is around 90Mbps.

2. Gigabit router: WAN/LAN Gigabit, the transmission speed bottleneck is about 900Mbps. The wireless supports 802.11ac protocol, and the dual-way WiFi transmission supports 867Mbps.

3. Mobile phones connected to a Gigabit router: The mobile phone supports the 802.11ac protocol and can support 433.3Mbps on the 5G wifi network (the mobile phone only has a single-channel wifi). In general, the mobile phone uses a Gigabit router plus 100M optical fiber. The speed bottleneck on the cat is the optical cat itself, and the maximum download speed is around 90Mbps.

4. 100Mbps router: WAN/LAN port supports 100Mbps, the transmission speed bottleneck is around 90Mbps, wireless only supports 802.11g/n, 2.4G WiFi supports a transmission speed of 144.4Mbps under dual-channel WiFi. The speed transmission bottleneck of the overall mobile phone on the 100M router plus 100M optical modem is the mobile phone. The maximum download speed can only reach 72.2Mbps.
