A frequency band is how wireless data is transmitted between devices. These bands are radio waves that transfer the data, and they can be either 2. The primary difference between 2. Instead, the 5GHz band gives less coverage but sends data at faster speeds. Coverage area vs. The 2. Instead, the 5GHz band provides a smaller coverage area than the 2.
The GHz range that a wireless device uses does not necessarily determine the maximum speed of the WiFi. The environment in which the network will be set up is what really should be considered. Interference can slow down a network significantly and reduce its scope as well.
For instance, for the 2. Instead, for the 5GHz band, cordless phones, radars, digital satellite and perimeter sensors are the most common sources of interference. When multiple devices attempt to use the same radio space, overcrowding happens.
A negative connotation of the 2. Finally, you should be aware that the cost of access points supporting 5GHz is higher than supporting 2. Furthermore, many 5GHz devices also support 2. A solution for 2. The Tanaza Powered Devices with dual-band can be: Selectable dual-band.
A selectable dual-band device offers a 2. Simultaneous dual-band. A simultaneous dual-band device broadcasts separate 2. With Tanaza, you can also assign the same SSID to both bands, so the access point only sees a single network, even though both bands are operating. The advantage of having both bands running simultaneously usually outweighs the cost difference. Discover the Tanaza Powered Devices. There are some disadvantages to going to a 5GHz wireless network.
One is that the higher the frequency of a wireless signal, the shorter its range. For example, 2. 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. Another disadvantage is that 5GHz equipment does not readily mix with 2. This is a consideration if you're upgrading a current large wireless network installation. If you wanted to mix an already installed 2.
Cost is another factor. The popularity of 2. One perceived advantage of a higher frequency is speed. However, because so many devices use the 2. The 5 GHz band is much less congested, which means you will likely get more stable connections. On the other hand, the shorter waves used by the 5 GHz band makes it less able to penetrate walls and solid objects.
Of course, you may also be able to mitigate that shorter range through the use of range extenders or mesh Wi-Fi systems , but that will mean a bigger investment. The good news is that most modern routers act as dual- or tri-band routers. A dual-band router is one that broadcasts both a 2. Dual-band routers come in two flavors:. A tri-band router broadcasts three networks simultaneously—two 5 GHz signals and one 2.
The reason for this is to help alleviate network congestion. If you have multiple devices that really use a 5 GHz connection heavily—like streaming high-resolution or even 4K video—you might benefit from spending a bit more on a tri-band router. First things first.
Wired connections offer a lower latency, no dropped connections due to interference, and are just plain faster than wireless connections. If you currently use 2. If you live in a crowded apartment complex with dozens of wireless routers, baby monitors, and other 2. Instead, think about how you use each device. If a device only supports 2. If a device supports both, think about whether you really need to use 5 GHz.
Does that device need the higher speed or are you mostly checking email and browsing the web? Is the device experiencing dropped connections on the 2. Are you okay with the device having the shorter effective range that comes along with using the 5 GHz band? In short, we recommend using 2. This will help low-use devices from competing on the 5 GHz band and, in turn, keep congestion down.
Hopefully, this gives you the information you need to make a decision about whether you need 5 GHz Wi-Fi in your life and how best to use it if you do. Also keep in mind that no matter what you choose, you should also take the time to optimize your wireless signals by selecting an appropriate channel on your router.
