The most advanced form of computer networks are Wide Area Network (WAN) and Wireless Wide Area Network (WWAN).

Both Wide Area Network and Wireless Wide Area Network are interrelated and share moreover same characteristics. Wide Area Network is a form of computer network which is been used in several areas of the world. Whereas, Wireless Wide Area Network is a kind of computer network which is of recent origin and now been widely used by many people of the globe.

Let’s discuss something about Wide Area Network as well as Wireless Wide Area Network.

What is WWAN

How Does It Work?

Whether you are a travelling salesperson, a technician, remote worker, or just someone who needs to be online always, Wireless WWAN is the best solution. So, how do you get it? A WWAN card is installed in your compatible laptop or comes with a WWAN card pre-installed. Then you get a sim card from your cellular phone provider tied to your cell phone account. Your connection uses the data connected to your existing phone plan.

When you turn your laptop on the system will try and connect through a wired connection first, because that will always be your best bet. After that, it will try to connect to wireless or wifi, your next best option. If it fails at these, the WWAN system will then use the cell connection to connect via the sim card. This is all happening instantaneously, then you’re connected!

Local vs. wide area
Both connections have their advantages and downsides.

WLAN
+ Most computers come with WLAN technology built in
+ It’s easy and affordable to set up a WLAN network in your home using a router and Internet service provider (ISP)
+ WLAN connections are commonly found in homes, offices, hotels, coffee shops and airports and are sometimes free to use
+ WLAN keeps you constantly connected to your network as your move around your house or network area
+ With WLAN it’s easy for small businesses to grow and connect more users without adding wires
+ WLAN is typically faster than WWAN
– The area covered by WLAN is fixed and typically small
– Because WLAN uses radio waves, signal strength can sometimes be compromised
– When WLAN is not free, users must usually purchase usage in 24-hour increments, knowing they’ll often use only a few hours of that time.

WWAN
+ WWAN provides regional, nationwide and global wireless coverage
+ Insert the WWAN card from your service provider or even easier, select a notebook with built-in WWAN technology (such as an HP Mobile Broadband card) and then contract with a service provider
+ WWAN provides better security than WLAN thanks to built-in 128-bit encryption4
+ Utilize cellular technology to securely transfer data or connect to the Internet4
+ Ideal for users away from home needing to connect virtually anywhere in their coverage area
– ISP contract may cost more than WLAN for those who rarely need or use wireless Internet access
– Replacing a lost external WWAN card can be costly (a built-in version may be a better choice)
