Two frequency bands offer advantages over single-band networks
Dual-Band Wireless Networking, In wireless networking, dual-band system is capable of transmitting in either of distinct trendy frequency levels.
Modern Wi-Fi domestic networks characteristic twin-band broadband routers that support both 2.Four GHz and 5 GHz channels.
First-generation home community routers produced throughout the late Nineteen Nineties and early 2000s contained a single 802.11b.
Wi-Fi radio running on the 2.Four GHz band. At the identical time.
a vast wide variety of commercial enterprise networks supported 802.11a (five GHz) devices.
Tip: The first twin-band Wi-Fi routers have been constructed to support mixed networks having both 802.11a and 802.11b clients.
Starting with 802.11n, Wi-Fi standards started out which includes simultaneous dual-band 2.Four GHz and 5 GHz help as a preferred function.
This inclusion approach that almost each present day router is considered a twin-band router.
Benefits of Dual-Band Wireless Networking
By supplying separate wireless interfaces for every band, dual-band 802.11n and 802.11ac routers offer maximum flexibility in setting up a home community.
Some home gadgets require the legacy compatibility and greater signal reach that 2.Four GHz offers at the same time as others may additionally require the additional network bandwidth that five GHz gives.
Dual-band routers offer connections designed for the needs of each.
Many Wi-Fi domestic networks be afflicted by wi-fi interference springing up from the superiority of two.4 GHz purchaser devices.
like microwave ovens and cordless telephones, all of which can most effective function on 3 non-overlapping channels.
The potential to apply 5 GHz on a twin-band router enables keep away from those problems due to the fact the technology supports 23 non-overlapping channels.
Dual-band routers additionally include Multiple-In Multiple-Out radio configurations.
The combination of numerous radios on one band together with twin-band assist offer much better.
overall performance for domestic networking than what single-band routers can provide.
Dual-Band Wireless Routers
For houses that have many competing wireless gadgets.
Google Wi-Fi is taken into consideration one of the top router selections. Its system includes three satellites, called Wi-Fi points.
each of which covers 1,500 rectangular toes for a whopping overall of 4,500 square feet of included coverage.
It uses beam-forming technology, which robotically routes gadgets to the strongest signal.
Dual-Band Wi-Fi Adapters
Dual-band Wi-Fi network adapters comprise both 2.Four GHz and 5 GHz wireless radios, just like twin-band routers.
In the early days of Wi-Fi, a few pc Wi-Fi adapters supported both 802.11a and 802.11b/g radios in order that someone ought to join.
their computer to enterprise networks during the workday and domestic networks on nights and weekends.
Newer 802.11n and 802.11ac adapters also can be configured to use both band, however no longer both at the equal time.
Dual-Band Phones
Similar to twin-band wi-fi network device, a few cell phones also use or greater bands for mobile communications break free Wi-Fi.
Dual-band telephones had been in the beginning created to help 3G GPRS or EDGE records offerings on zero.
Eighty five GHz, zero.9 GHz or 1.9 GHz radio frequencies.
Phones from time to time help tri-band or quad-band cell transmission.
frequency tiers to maximise compatibility with different styles of phone networks.
beneficial while roaming or touring. Cell modems switch among exclusive bands but do not help simultaneous twin-band connections.
