Wireless technology has radically transformed the world of computing. While traditional cable networks remain popular, wireless networks are fast becoming the normal setup in homes and offices. Wireless connectivity is now considered by many people to be an essential feature of new routers and modems. It may add a bit extra to the price, but the savings in time and money gained from not having to use cables are more than worth it. But too many wireless devices in the same area can cause interference if they all use the same frequency band. Replacing an ordinary wireless router with dual band router is one way to solve this tricky problem. A dual band router can communicate with devices in two different bands, reducing the chance of conflicts when they are operating at the same time.
An ordinary broadband modem is sufficient to connect one computer to the internet, but an additional device is required if several computers need to use it as well. This is often the situation in homes and offices where everyone has their own computer but there is only one broadband connection. The device that brings them all together is called a router, because it routes the data traffic between the computers and other networking devices. A router may be a separate unit or it may be part of the modem itself. There are wired routers that use Ethernet cables and also wireless routers that do not need cables at all. A dual band router is a type of wireless router that operates on two different frequencies.
It is safe to say that few people look forward to the time-consuming and expensive task of installing networking cables, but that is what many homeowners face when they setup a computer network. Running the cables through the roof spaces and wall cavities in a typical home can be a dirty and dangerous job. This was the only option in the past, but thankfully, those days are long gone. Wireless technology has made great strides in recent years and is now a standard feature of many networking devices. It is now possible to setup an entire computer network in a building without using any networking cable. As mentioned before, multiple wireless devices leads to greater interference, but having them use a dual band router is a good step towards minimizing this problem.
In wireless terminology, a band refers to a small range of frequencies. Bands are used to regulate the spectrum and stop services from interfering with each other. There are many bands in use today, such as the AM and FM bands commonly used by radio stations. Dual band is a term used to describe any wireless device that can operate in two different bands. A dual band router is usually more expensive than an ordinary router but the difference in price is not that large. Of course, there is no benefit to having a dual band router if every wireless device that uses it operates in the same band, so it may be necessary to upgrade other parts of the computer network to get the best performance.
Practically every dual band router operates in the 2.4GHz and 5GHz bands, and many models are capable of operating in both bands simultaneously. Before buying a wireless router, check its list of supported standards to ensure that it will work with other devices. Most routers can be configured with an ordinary web browser but some require special software to be installed first. A wireless router should also have Ethernet and USB ports to support networking devices that do not have wireless connectivity. The maximum range of devices that use the 5GHz band is often slightly less than other wireless devices, and it is reduced even further is there are walls and floors between them and the router. Apart from that minor problem, the performance of a dual band router should match or exceed that of a conventional wireless router.
