What is dual band? Learn more with real-life examples. In wireless networking, dual-band equipment is capable of transmitting in one of two standard frequency ranges. Modern Wi-Fi home networks feature dual-band broadband routers that support both 2.4 GHz and 5 GHz channels. Benefits of Dual-Band Wireless Networking By supplying separate wireless interfaces for each band, dual-band 802.11n and 802.11ac routers provide maximum flexibility when setting up a home network. Some home devices require the legacy compatibility and greater signal reach that 2.4 GHz offers, while others may require the additional network bandwidth that 5 GHz offers. Dual-band routers provide connections designed for the needs of each. Many Wi-Fi home networks suffer the prevalence of 2.4 GHz consumer gadgets, like cordless phones, which use Frequency Hopping Spread Spectrum modulation. 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.​ TP-Link Store: https://s.daraz.com.bd/s.yGrM?cc
