If, on your network, you have 5GHz equipmnet AND anyone might use devices like iPads, iPods, WiFi enabled smart phones and other devices that can only use 2.4GHz, dual band routers will be required. Unless you control and limit the devices used on your network, a dual band network works best. Have It Both Ways - Dual Band Wireless Networking However, If you have little control of what network cards your users are using or of access points, then a 2.4GHz system may be a better choice. In general, if high performance and over crowding of other 2.4GHz networks in the area is an important factor, then 5GHz wireless network may be the answer. There are a few things to consider before making the jump.
Which Network?Īs you can probably see, switching to 5GHz requires planning. There are 2.4GHz products using 802.11g that can match or can be faster that 5GHz 802.11a by using paired radios inside access points instead of one which can increase capacity up to 108Mbps. However, 5GHz networks are not necessarily faster than 2.4GHz. One perceived advantage of a higher frequency is speed.
The popularity of 2.4GHz means that wireless network components such as access points, antennas and network cards are more easily available and costs less. If you wanted to mix an already installed 2.4GHz network with a 5GHz network, you would have to make sure all components of the network is dual band.Ĭost is another factor. This is a consideration if you're upgrading a current large wireless network installation. This can limit an access points reach inside buildings like homes and offices where many walls may come between a wireless antenna and the user.Īnother disadvantage is that 5GHz equipment does not readily mix with 2.4GHz equipment already installed. 5 GHz networks do not penetrate solid objects such as walls nearly as well as do 2.4 GHz signals. For example, 2.4 GHz networks cover a substantially larger range than 5 GHz wireless networks. One is that the higher the frequency of a wireless signal, the shorter its range. There are some disadvantages to going to a 5GHz wireless network. Disadvantages - Shorter Range, Cost, Old Component Replacement
