Wireless wide area network

Wireless wide area network definition

Wireless wide area network refers to a type of wireless network that covers large areas, often spanning several kilometers to even thousands of kilometers. Unlike wireless local area networks (WLANs), WWANs such as 4G (LTE) and 5G provide connectivity across much larger geographic areas, typically through mobile network operators.

Wireless wide area network benefits

  • Coverage. Unlike Wi-Fi (which is a type of Wireless Local Area Network or WLAN), WWANs cover vast areas. So, even if you’re traveling to another country, you would remain connected.
  • Cellular technology. It primarily relies on cellular towers and infrastructure. Devices connect to the network using a SIM card, which identifies you as a user and manages your services.
  • No need for physical infrastructure. You don’t need routers and cables, because your smartphone can communicate with the network by itself.
  • High mobility. Whether you’re using a smartphone or laptop with a cellular modem, you can access the internet, make calls, or send messages while on the move.
  • Network evolution. As technology advances, WWAN speeds and capacities have increased dramatically. For instance, the evolution from 3G to 4G/LTE brought significant speed improvements, and 5G promises even faster speeds, lower latency, and the ability to connect many more devices simultaneously.
  • Reliability: Cellular networks are often more reliable in areas where other forms of internet connection (like DSL or cable) might not be available or consistent.
