SpiderMesh Wireless Network

SpiderMesh is a cooperative wireless mesh network technology. It’s the first LPWAN mesh.

Designed with scalability in mind, it is the only wireless mesh network on the market that tackles both wide area and low power on a large scale, without sacrificing reliability and simplicity. It tackles the difficult task of connecting millions of devices on the same network, seamlessly.

How We Compare to Standard Mesh

Why is SpiderMesh unlike any other wireless mesh network on the market today? The bit-level message synchronization.

Traditional mesh networks focused on self-configuration, self healing and did not need a direct line of sight. These are great factors, however, the lack of scalability and the power consumption needed for a large area were important issues that we decided to tackle in order to make this an ideal mesh network.

SpiderMesh is a smart mesh technology. It was built with one concept in mind: to offer a predictable, deterministic flow of information. Using very low power, the technology was designed to work in challenging environments and is completely scalable.

To give you a better idea of the differences between SpiderMesh and traditional mesh, take a look at these analogies below.

Using the Crowded Bar as an Analogy

Imagine that you’re at one end of a bar and your friend is a couple of feet away.

You’re trying to ask her if she would like another drink. However she can’t hear you because your other friends are speaking around you and the music is so loud. They may help you asking your friend if she’d like a drink but since nobody is saying it at the same time, the message isn’t properly communicated. You assume she heard the message but can’t be sure.

This is comparable to other similar mesh technologies on the market. No bit-level synchronization, no tracking of data and you can’t be certain when the message will be sent because of all the devices speaking at the same time.

If you compare this example to SpiderMesh technology, you and all your friends at the bar would be saying the same thing at the same time, and the message will come out clear. Your friend would hear the exact message, and you can be 100% certain she heard it and when.

Using Traffic as an Analogy

Imagine that each car is a message that needs to get through.

With other technology on the market, the traffic flow is managed with a set of rules such as red lights, stop signs, yield signs, etc. Unfortunately, this is not enough to guarantee a constant and uninterrupted flow.

Traffic jams occur all the time and are completely unpredictable. One bad decision from a single driver can cause an accident with serious implications such as traffic jam that stretches to other sections of the road network. Even by using our smartphones’ knowledge to get real-time insight on accidents and congestion, there is only so much that our apps’ wisdom can solve. The reality is that there will always be traffic and delays on our path as long as we have accidents, unpredicted behavior and flow.

Fortunately, there is a bright future ahead with the advent of smart autonomous cars. With intelligent, perfectly synchronized cars, drivers can’t make rash decisions anymore. As a result, a continuous car flow on the road network will mean several things:

  • We prevent accidents from happening

  • We can fit in more cars on the same roads

  • We can remove all the red lights and the set of rules for traffic control

  • We do not need any knowledge on the road network status anymore

  • We can predict the exact time to destination and the fuel needed for the trip

The Challenges of Wireless Mesh

The same challenges apply to wireless mesh communication. Standard mesh establish a set of rules to synchronize data transfer to the packet level (as did the old-fashioned road network with red lights). Unfortunately, these set of rules are not enough and as traffic increases with the network size, so do packet collisions (the accidents).

Messages are then being held up which result in increasing delays before they reach their destination. This is called network contention*. However, unlike the car example, broadcast messages cannot wait in the system. When a collision happens, the messages are dropped and the messenger has to repeat the message over and over again until it gets through, wasting energy in the process.

In recent years, a few more advanced mesh technologies have attempted to alleviate congestion with better traffic management. By geolocating nodes (such as the smartphone use in our previous example), knowledge of the status of the network allow those mesh to route messages through an optimized path in an effort to reduce the overall traffic as the network size grows. This added structure is an attempt to minimize both contention and power use. However, it’s still not enough, as we’ve seen in the car example. And this will increase hardware cost and can make the system a lot more complex. For example, in order to store all these extra routes, this will take up more memory on the chip, which leads to higher hardware costs. All in all, there is a lot more planning needed before deployment, it isn’t an easy set up. You have to plan ahead to see where the single point of failures are, or if there are enough redundancies.

SpiderMesh is the Next-Gen Wireless Mesh

We’re happy to say that SpiderMesh Technology has bypassed these issues. By synchronizing data to the bit level (rather than the packet level), the traffic behavior is akin to our futuristic autonomous smart cars example. The cars are all going the same speed, in an organized fashion, they are all synchronized. We prevent packet collisions from happening and in turn, are able to get a continuous and predictable data flow. As highlighted earlier in the car example, this means:

  • We prevent packet collisions from happening

  • We can fit in more data on the same large network (higher throughput)

  • We don’t need any knowledge of the network (no on-board storage for complex routing tables, lower chipset cost)

  • We can predict the exact time to destination (deterministic latency)

  • We can predict how much energy is needed to send a message through the network (deterministic power consumption)

As technology continues to play a more active role in our day to day lives, it was important for us to solve these key issues with current wireless mesh technology in order to keep up with the IoT.

Unleashing IoT’s Endless Possibilities

SpiderMesh can cater to so many applications because it’s flexible, adaptable, scalable, and deterministic.

The “Internet of things” (IoT) is becoming increasingly intertwined in our everyday life. It not only impacts how we live but also how we work. Wireless is the foundation of IoT, and we are key players in the connectivity of IoT over low power wide area networks (LPWANs).

Spidermesh is the first completely deterministic wireless mesh technology.

This means that you can predict exactly the amount of energy needed to transmit data and you know exactly when you will receive this data, no matter the scale and density of your connected devices.
