ADDING IT ALL UP
AC5300 and AC3200, ever wonder what do these numbers mean and how do manufacturers come up with these numbers? To begin, the numbers indicate the total data transfer rate supported by the routers and it is quoted in Mbps or megabits per second. 8 bits is a byte, so 5,300Mbps is equivalent to 662.5MB/s, whereas 3,200Mbps is 400MB/s.
Also important to note is this quoted total data transfer rate is achieved by adding up the bandwidth offered by all broadcasted networks. In the case of an AC3200-class router, its single 2.4GHz network offers 600Mbps while its two 5GHz networks offer 1,300Mbps. Add them all up and you get 3,200Mbps.
For AC5300 routers, because they support 4x4 spatial streams and a special new technology called NitroQAM, the maximum bandwidth of each stream is boosted. This results in 1,000Mbps on the 2.4GHz band and 2,150Mbps on each of the 5GHz band. Add them all up and you get 5,300Mbps.
