The Benefits of Wireless Devices

Wireless network devices usually fall into three categories;

    -Wireless Personal Area Network (WPAN) like Bluetooth, NFC or IR,

    -Wireless Local Area Network (WLAN) like WiFi,

    -and Wireless Wide Area Network (WWAN) like Cellular or Microwave.

While these devices are used in different situations, they have similar connection processes and distinct shared benefits.

1: The first benefit is portability. Untethered by cables, these devices go with you. For cellular devices, this means you don't need to find a connection point to use your phone, your magic rectangle just sits in your pocket and is always connected to voice and internet. For WPAN and WLAN, it means you don't need to worry about cables, a much cleaner environment. 

2: The second benefit is ease of use. You don't need to sit there tuning a radio receiver to make these devices connect, you just use the interface and the computer handles the standardized connection. For Cellular, you just pop in a SIM card and the device and the network handle everything. For WiFi, you can just select the network, enter the password and you're working. For Bluetooth, you just pair the devices and they magically work. With billions of users, the user experience has been prioritized by companies.

3: The third benefit is cross compatibility. These devices follow a standardized protocol so they work together regardless of manufacturer, origin, or date. Bluetooth devices work with other Bluetooth devices, WiFi devices can connect to WiFi (and even better if they're operating the same 802.11b-a-g-n-ac-ax, etc), and cellular devices can work on the network they're compatible with. If something bears the logo of the network you want to connect to, it should work. Unless it doesn't.
