ModernWi-Fihome networks feature dual-bandbroadband routersthat support both2.4 GHz and 5 GHzchannels.
Dual-band routers provide connections designed for the needs of each.
This is where the signal jumps all around the 2.4 GHz spectrum rather than sitting on one channel.

Microwave ovens may also interfere with wireless signals due to the radio signals they ‘leak’ during operation.
The ability to use 5 GHz on a router avoids these problems because the technology supports 23 non-overlapping channels.
Dual-band routers also incorporateMultiple-In Multiple-Outradio configurations.
At the same time, a significant number of business networks supported802.11a(5 GHz) devices.
Starting with802.11n, Wi-Fi standards included simultaneous dual-band 2.4 GHz and 5 GHz support as a standard feature.
This inclusion means that nearly every modern router is considered a dual-band router.
The first dual-band Wi-Fi routers were built to support mixed networks having both 802.11a and 802.11b clients.
It uses beam-forming technology, which automatically routes devices to the strongest signal.
Cell modems switch between different bands but do not support simultaneous dual-band connections.
