Wireless mesh networks explained

Wireless technology is evolving and mesh networks are at the forefront of improving your connection and accessibility.

The emerging technology is possibly the solution for seamless internet connections. They are able to establish an easy and effective way to connect wirelessly across large areas. For the time being, Mesh networks are being offered on a far smaller scale, where mesh technology removes the need for repeaters or Wi-Fi range extenders.

If you live in a large home or workspace, you’ve probably had trouble with your Wi-Fi connection when you are far away from the router. Service providers have offered extenders, boosters or repeaters that pick up the signal and transfer it beyond the router’s range, but, more often than not, they cause more problems than they solve. There are two main problems: a) there is a creation of an additional network with your device likely not being smart enough to connect to the different network created by the repeater. It will probably stay on a weak signal from the original network unless you manually disconnect and reconnect. Furthermore, repeaters often operate on a single channel, which can cut your bandwidth in half.

With a mesh network router, you can establish a single wireless network. You’ll get the full speed and functionality of your router and can connect from anywhere. They are plug-and-play and work without any direct lines. This solves the first problem of repeaters. The second part is that it establishes a network at (commonly) 5 GHz that’s dedicated only to communication between the mesh router and the satellite or direct line. That means that the bandwidth is not compromised.

Now, while this would be profitable for retailers on a small scale, the truth is that it can go even further, but this is made problematic by backhaul nodes. Even in a wireless mesh LAN, there comes a time when information needs to return to a wired access point to reach the wider Internet. Getting that information back to the access point is called backhaul. Small wireless mesh networks handle backhaul without needing special configurations. In larger mesh networks, like those for cities or large companies, certain nodes need to be dedicated as backhaul nodes. The other nodes send all outgoing information straight to one of the backhaul nodes, which will send it to the wired access point without unnecessary hops.

In essence, this means that mesh networks don’t scale very well. Although the technology is there, routing protocols are currently unable to scale over a few hundred nodes and network coverage is constrained by the limited range of wireless user devices. A technology is needed that uses powerful microwave transmissions that broadcast signals over long distances.With that technology, mesh networks can exist across cities.

With that technology, mesh networks can exist across cities. If the government can set up a few dedicated backhaul nodes in strategic areas, it can connect citizens and public services over high-speed internet connections. This is especially useful for commuters, the provision of public services and in the case of emergencies such as natural disasters. Mesh networks are also self-healing because if the connection from one node to another is lost, the network automatically connects to a different node in order to find its route back to the direct line, which is useful in scenarios such as power outages. This can also be a solution to provide those excluded from internet services in the developing world with a connection in a cost-effective way that doesn’t require much infrastructure and is economically advantageous for almost anything from education and healthcare facilities to the hospitality industry and in temporary venues.

Wireless mesh networks are going to change the way we experience the internet and are able to give us an always-on experience wherever we go, without pesky interruptions and decreased bandwidth.
