The relationship between broadband and download speed
The broadband 100M we use here refers to the bandwidth, Mb = Mbit and the M of the world download speed refers to the byte. If MB = MByte is to be directly converted, 1MByte = 8Mbit means that the actual downlink rate per second of 100M fiber is 100Mb / 8 = 12.5MB, of course this is the theoretical peak
MIMO stands for Multiple Input Multiple Output. It is widely used in the fourth generation of mobile communication technology standards. When the signal sent by the radio is reflected, multiple signals are generated. Each signal is a spatial stream. Systems using single input single output (SISO) can only send or receive one spatial stream at a time. MIMO allows multiple antennas to send and receive multiple spatial streams at the same time, and can distribute signals to or from different spatial directions, so it can increase the data transmission rate.
Dual-band refers to a wireless router that operates in the 2.4GHz and 5.0GHz bands at the same time. Compared with a single-band wireless router, it has a higher wireless transmission rate, stronger anti-interference, stronger wireless signals, and more stability. High, not easy to drop, dual-band wireless routers have become the mainstream development trend of wireless products.
802.11ac can be said to be the fifth-generation WiFi standard. The biggest difference from previous generations lies in dual-band applications, faster speeds, and wider coverage areas. Starting with 802.11ac, the transmission speed reached 1200Mbps, and it works at 2.4GHz + 5GHz.
Bandwidth is the width of the channel. The total bandwidth of 2.4GHz is 60MHz, the total bandwidth of 5GHz is 460MHz, and each channel is 20MHz. Some protocols support bundling adjacent channels together to increase bandwidth.
It is a router with a wireless coverage function, which is mainly used for users to access the Internet and wireless coverage. The wireless router can be regarded as a transponder, which forwards the broadband network signal connected to the wall in the home to the nearby wireless network equipment through the antenna.
