The repeal of net neutrality laws in America has led many citizens to seek ways to connect to the internet other than through the state's powerful service providers.
One of these options is “mesh networks.” Mesh networks already existed, but in different forms.
But first, let's see what a mesh network is
When you search on Google, the results will be options to buy some oddly shaped WiFi pods from a variety of companies. They come in all shapes and sizes: cylindrical, hexagonal, and flat squares.
This is the first type of mesh network you can buy for your home. Placing these pods throughout a home or office can boost WiFi service everywhere – so there are no dead spots.
This home network provides a good, tangible idea of the broader concept of mesh networks:
When learning about mesh networks, you will come across the word “node.” Mesh networks are a series of nodes that communicate with each other. The word “node” simply means a point of connection.
Here, each WiFi pod serves as a connection point, which spreads the signal from one pod to the next (a mesh of nodes). It may be helpful to think of these nodes as the systems of telecommunications satellites that orbit the Earth today, strategically spaced to send and receive signals around the world.
This spread signal is the critical difference between mesh networks and the traditional WiFi found in most homes. Traditional networks use a single router to broadcast a WiFi signal. But if you're too far from a router, the connection may not reach you.
In contrast, WiFi mesh networks – like Google's WiFi networks – are intended to be placed throughout the home, on surfaces and furniture, to transmit WiFi from your modem hub.
How do people use mesh networks as an “alternative” way to connect to the internet?
This is the second way such a network can be used. It is a way to access the Internet without relying on major Internet service providers, or ISPs, such as Verizon and Comcast to connect you through their networks.
Some people are interested in this option because – with the repeal of net neutrality rules, telecoms can now favor certain types of data or information, allowing companies to start manipulating how you use the internet.
In response, some individuals are taking it upon themselves to offer “community networks.” These are certainly not available everywhere, but they could slowly become a very common phenomenon.
An existing example – with a growing community – is NYC Mesh, in New York City. The network has self-contained “nodes” spread around the city. This network does not rely on the dominant ISPs, but rents data from a local data center (such as in midtown Manhattan) and then uses rooftop antennas (nodes) to spread the internet.
This data, NYC Mesh notes, is not monitored or controlled by any ISP.
Are there any large, national mesh networks anywhere?
Yes, in Spain. This network is called Guifi. According to NYC Mesh, this network “covers large parts of the country.”.
This is achieved by having a “backbone” of many long-distance WiFi connections and even their own shared fiber cables.
