Description
The Optixstar K251a-21 of Huawei is a router, a device that connects other devices (e.g. computer, mobile, television) either wirelessly or with a cable, and shares internet access. It needs to be connected to a modem to access the internet. It emits a signal at two frequencies, 2.4 & 5GHz. It offers higher speeds compared to single band and can connect more devices. The 2.4Ghz frequency is the most widespread and has a long range. The 5Ghz provides higher speeds than 2.4Ghz but is more sensitive to obstacles (e.g. walls) that reduce its range. This difference, as well as its more limited use, helps to have fewer interferences from other networks.
