Dual Band Wireless Routers have the capability to transmit on the 5 GHz and 2.4 GHz wireless band. 2.4GHz though more widespread in usage (all 802.11b and g devices run on 2.4GHz only) has only 3 non-overlapping channels for transmission, which are crowded due to a lot of interfering devices- other Wi-Fi access points, microwave ovens, cordless phones, Bluetooth devices, baby monitors, etc. all make for a noisy environment which increase interference and degrade the performance. 5GHz channel is much cleaner with less interference with 23 non-overlapping channels – 8 times more than 2.4GHz for transmission, which makes it suitable for applications like Video streaming and Gaming which are very sensitive to packet loss and delays. There are two types of Dual Band Routers in the market: Simultaneous and Selectable Dual Band Routers with very different capabilities and performance:
|Simultaneous Dual Band||Selectable Dual Band|
|Twice the bandwidth||Same bandwidth as single band router|
|Dedicated Wifi Network for Video and Gaming||Single Wifi network for all devices – No different than single band router|
|Separate networks avoid interference||Single network is more crowded|
|Two separate Wifi networks operating simultaneously||Selectable Single Band Wifi network|
Simultaneous Dual Band Routers provide the ultimate in flexibility and performance by providing two independent, dedicated networks.
