We can communicate or access the Internet from our smartphone anywhere you have mobile data signal or coverage. This is because our mobile device is integrating a large network called WWAN.
This type of wireless wide area network allows users to connect thanks to the technology it uses, which assigns a large number of repeater antennas the work of connecting with each other to cover as much territory as possible.
We will see below what is a WWAN network and what are the most important characteristics. We will also analyze the difference between a WAN network. Do not miss any details of this post, since we will see the most representative examples for this type of networks.
What is a WWAN network and what are they for in computing?
“Wireless Wide Area Network” Or simply “WWAN”, is a wireless wide area network. With this kind of wireless network, a special technology is needed, more precisely a cellular network, to be able to provide a telecommunications service efficiently. Within these services is the Internet access, phone calls and also video streaming.
The WWAN network It has an encryption and authentication protocol to have more secure communications, but they do not always succeed. This is because wireless networks they are more vulnerable than those powered by cables.
What are the most important characteristics of a WWAN network?
A WWAN network has unique characteristics that differentiate it from the rest of the types of computer networks that exist today. Here are the most important ones:
- Among the main characteristics of this type of extensive networks is the ability to offer wireless Internet at high speed, as well as transmitting audio images and videos in real time.
- Also noteworthy is its voice transmission capacity, being as efficient as a physical network.
- Depends on different antennas They must be installed in different geographical areas in order to intercommunicate and be able to offer a wireless network service.
- They are provided by telecommunications companies or service providers that have significant financial investments to do so. In other cases there are closed WWANs that are created by companies or other kinds of organizations.
- The configuration needed to access a large wireless network too easy and it’s done with intuitive steps.
- Gives the user the ability to move within the coverage area without having to configure the receiving device to be able to access the benefits that this wireless network offers.
WWAN vs WAN How are they different and which is better network?
The first thing we should define is the meaning of each of these networks, WAN (Wide Area Network) is an area network that covers a wide geographical area through wired technologies and, in some cases, by air. While WWAN also covers a wide territorial area, but its technology is completely wireless.
Regarding installation costs, maintenance and operation, a network WAN is much more efficient than a WWANas cables are less expensive than all the equipment needed for air connections. But with regards to the installation procedure, a wireless network will always be easier.
As we mentioned before, if we analyze security, a WWAN network is much less reliable due to the characteristics of wireless networks. Therefore, the intervention of intruders is the order of the day in this type of network.
If we have to consider the speed of both networks, we can say that the transport speed of a WAN network is lower than WWAN. But the same does not happen with the performance, although both have a good performance, when there are climatic factors, the proper functioning of the WWAN it can be interrupted.
Finally, it would be necessary to talk about the mobility that these networks have. WWAN shows an excellent result, while the networks WAN excel at low level of disruption of connections.
What are the most used topologies for this type of wireless networks?
Network topology refers to the way a network is designed in which it can be physically or through internal characteristics that a program has with which it can be joined.
In this way, since WWAN is the network with the widest range within the entire set of wireless networks, we can mention that this type of network is geometrically linked with its nodes or devices that are connected to each other through a type “point by point” over short distances or by means of a “Star model” in the rest of the geographic area. But if we consider a closed network, we can speak of a topology that connects with a type of “Mesh net”.
Types and examples of wireless wide area networks
To talk about the examples, we would first have to divide between the WAN and WWAN networks. For the first case, we can mention the service of Internet provided by telecommunications operators. Also a good example is the TV on demand offered through the web or a Fax to email service.
When we refer to a WWAN network, we have to mention all those wireless networks that are available in our territory to be able to access the Internet through mobile data or communicate by telephone. For example, we can name EDGE, 3G or GPRS. But we cannot ignore those WiMAX services, where a geographic area installs an antenna and this area can have access to the signal emitted by it up to 70 km away.
Another example of these networks is Mobitex, which runs in our country on channels from 400MHz to 450MHz, providing a service to the military, police and firefighters. You can also mention as an example to LMDS which offers an Internet service in private networks.
More examples of this type of Internet access protocols for WWAN networks are:
