Dual band wifi range extender ( also called wifi signal booster) can boost both 2.4ghz wifi & 5ghz wifi signals from original source. OR you can connect to original 2.4ghz signal and extend wifi range to 5ghz network OR vice versa that is connect using 5ghz wifi and extend signal to 2.4ghz wifi network.

Dual Band wifi signal booster are a little costlier than single band wifi booster however they perform way better than a single band wifi range extender. Infact I wouldn’t recommend single band n wifi booster to anyone unless you live in rural areas near woods where next house far away.

Here is the list of Dual Band Wifi Boosters/Range Extenders available in India ……
