Is wifi at home slow?Then you should use the 5GHz band | Mac
■ 2.4GHz band is disadvantageous in terms of speed
Many of the current WiFi routers, including the AirMac series, are communication standards "IEEE802.It corresponds to 11 ".In 11n, 2 to communication.Two types of frequency bands, 4GHz / 5GHz, can be used, and the communication speed does not change in either bandwidth.But in fact, 2.The 4GHz band communication is disadvantageous in terms of speed.Not only WiFi communication devices but also Bluetooth devices use this band, and they also interfere with microwave ovens.On the other hand, the 5GHz band has a small number of corresponding communication devices, and it is difficult to receive interference from other devices, making it easier to speed.
■ How to use the 5GHz band with priority
AirMac Extreme and Time Capsule released after 2009, AirMac Express after 2012.It supports "dual bands" that can use both bandwidth of 4GHz / 5GHz at the same time.In these models, 2.Since the communication of the 4GHz / 5GHz band can be explicitly distinguished, it can be connected by specifying the 5GHz band from a Mac or iPhone.The setting procedure is as follows.First, start "AirMac Utility", select the bass station icon that builds wireless LAN, and click the "Edit" button (see the figure below).
Next, click the "Wireless Option" button at the bottom of the "Wireless" tab of the displayed window.The option setting panel appears, so check the "5GHz network name" and enter the name.It is good to make the name that you can immediately understand if it is a 5GHz band.After giving the name, click "Save".This is 2.The network of the 4GHz band and the 5GHz band will be displayed individually.
■ Specify the priority in the "Network" panel
Open the Mac "System Environment Settings" → "Network" panel.You should be able to specify the 5GHz band network set earlier in the "Network Name".Click "Details" to display the detailed screen, and drag the network name of the 5GHz band at the top with the "Wi-Fi" tab "network name you have used".This is now connected to the 5GHz band with priority.
■ Check if connection is possible
You can check whether the WiFi communication function of your Mac is compatible with the 5GHz band on the menu bar menu.If it is supported, a 5GHz band network name should be displayed on the list.This is the same for iOS devices.In the case of an iPhone, it is not displayed before the iPhone 4S that does not support 5GHz, but it can be seen with the iPhone 5.The same is true for iPad's Retina model and iPad mini.Especially in areas with intense radio interference, such as urban areas, the communication speed is clearly faster just by changing the communication band.In fact, it can be almost twice as fast, and many people can experience the effect.If you always think that WiFi is late, please try it.
