Wireless connections use radio signals to send and receive transmissions. The two dominant forms of wireless connection are Wi-Fi, which is based on the IEEE 802.11 standards, and broadband connections that use cellular phone networks such as 3G and 4G.

Microsoft has put a lot of development effort into making wireless networking seamless and easy to use. If your wireless adapter is enabled, chances are that it will be automatically configured for you and will detect available networks. You just need to know how to select a wireless network and authenticate your device.

You can set all of your wireless and network settings in the Wireless section of the PC Settings page, which is accessed from the Settings charm. Windows learns your network preferences over time and prioritizes one wireless or mobile broadband network over others. Since Wi-Fi is cheaper, has lower latencies (greater transfer rates), and allows for higher data caps, when Wi-Fi is available mobile broadband connections are not used. On a mobile device, this also has the effect of lengthening battery life. When Wi-Fi isn’t available, your device switches back to your broadband connection.

Microsoft has put a lot of effort into making mobile broadband easy to use. When you insert a SIM card or a USB transceiver into your PC, Windows 8 automatically recognizes which vendor’s device it is, installs the correct drivers, and connects you to the service’s network. That’s pretty slick. If the device is unlocked and can access multiple service providers, Windows 8 allows you to choose from the different possibilities within the Networks bar. You can also choose another network provider and even be directed to subscribe to a service.

One new feature you might not notice is that when you reconnect a PC to a Wi-Fi network, it connects in about a second—even faster than your display is available. Windows 7, by comparison, took about 12 seconds to establish a network connection.

If you have a limited bandwidth connection, you may want to show the estimated data usage and set it as a metered connection.

The metered connection option is useful if you are on a 3G or 4G network and have a limited data bucket. When this option is enabled, device software and app updates will not download over your broadband connection. Those data transfers are performed when another network connection, such as a home Wi-Fi network, is enabled.

Windows 8 introduces a feature called “airplane mode,” which turns on and off all wireless communications with a single switch. In airplane mode, Wi-Fi, Bluetooth, and any other wireless connections are taken offline. Airplane mode is not available when your device is connected to an Ethernet network. When Windows 8 is offline, a variety of system functions, such as Live Tiles and automatic updates, do not function. You access airplane mode from the Networks bar in the Settings charm.
