Wireless Local‑Area Network adapter

WLAN adapters use Wi‑Fi technology and allow your devices to connect to a wireless router. Your computer may have an internal

(expansion cards or integrated to the system board) or an external WLAN adapter.

Wireless Wide Area Network adapter

Wireless Wide Area Network (WWAN) controllers allow wireless connectivity through cellular tower technology. This technology is

mainly available on phones, tablets, and business-class laptops. A SIM card and a service contract may be required for WWAN

connectivity.

Bluetooth

Bluetooth allows you to connect other Bluetooth-enabled devices to your computer or tablet, over a short distance. Bluetooth

devices may include phones, headsets, keyboard, mice, printers, and so on. Bluetooth adapters can be internal (expansion cards or

integrated to the system board) or external.

More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that

forward data at high speed along the optical fiber lines of the internet backbone.

Near-Field Communication

Near-Field Communication (NFC) allows you to exchange data between two devices by touching the devices with each other or by

bringing them to close proximity. You can use NFC-enabled devices to read NFC-tags, make payments, share files between

compatible devices, and so on.

On Dell laptops and tablets that support NFC, it is enabled by default when wireless in turned on.

NOTE: For connecting your NFC-enabled device to your computer or tablet, see the documentation for your device.

NOTE: File sharing works only between devices using Windows operating system.
