Dual band routers are among the most advanced networking technologies available on the market. They support multiple frequencies and enable customisation of your wireless network. By understanding the benefits of dual band routers you can better assess whether they are suitable for your budget, equipment and networking needs.
Step One
Signal Interference - The most important benefit of dual-band routers is the ability to switch between 2.4GHz and 5GHz frequencies. Because many household devices give off radio frequencies in the 2.4GHz range, they often interfere with a Wi-Fi signal. Interference can slow down Internet speeds, reduce Wi-Fi range and cause intermittent signals. With a dual-band router you can switch to the 5GHz range and enjoy faster, more stable Internet service.
Step Two
Compatibility - Dual-band routers are designed to work with a range of wireless networking equipment. Because they support both 2.4GHz and 5GHz, they should work with any type of network adapter. However, in order for you to access the benefits of the interference-free 5GHz range, your computer and network adapter must support it. If you have older computers and adapters that cannot use 5GHz, you are better off buying a cheaper standard router.
Step Three
Range - Five-gigahertz wireless Internet will have a shorter range than 2.4GHz wireless Internet because it is on a higher frequency. In order for you to take advantage of the dual-band benefits, your computers must be within the range of both frequencies. Ranges vary from router to router, and range boosters to wireless repeaters can extend them. To get the most out of a dual-band router, purchase one that can use both frequencies simultaneously.
Step Four
Feasibility - What this all means is that if you pick a next generation wireless standard, consider what your requirements are. Most users won’t actually get that much benefit going from a wireless-G to a wireless-N device. However, if connection stability or file transfer rates are a problem, switching over to wireless-N will make a qualitative difference in performance.
