Q

Tony, what is a mesh network?

A

A mesh network is a topology where all nodes are connected. It can use a single Internet access gateway to connect to each network node; or let the nodes connect and communicate with each other themselves. Mesh networks can easily extend the range of wireless devices to an entire area, such as an office, home, or even outdoors.

Each device in the network has two ways to send and receive information. The entire network is independent of one device for communication, so if one node is unable to communicate, the network will continue to work through the other nodes. Each network node and interconnected devices (such as light bulbs, TVs, tablets, appliances, etc.) can communicate back and forth using a variety of wireless standards.

Q

How do mesh network nodes work with IoT devices in your home?

A

Today’s mesh networking devices are not limited by broadband signals. They can communicate via multiple standards to extend the range of networks such as Wi-Fi, cellular, Bluetooth Low Energy, ZigBee, Thread, and more.

In a full mesh network, all devices are connected and can communicate with each other. This provides full redundancy and maximizes network performance. Mesh networks are an effective and economical solution for extending signal range throughout the home. This increases reliability and ensures real-time communication with all devices.

In addition, some of these devices can store data. This stored data can save costs for network users, further improve network reliability, and enable smarter data-driven applications.

Q

What benefits does mesh networking bring to home IoT?

A

Mesh networks offer a self-healing algorithm that automatically selects the best path to send data even if some nodes unexpectedly lose connectivity.

The algorithm only supports connections that are available. Even if some devices are not working, the entire network can still work. Mesh networks also allow devices to communicate directly with each other without going back to a gateway. Mesh networks are always accessible, always online, and highly reliable, bringing tangible advantages to IoT applications.

In addition, there are the following advantages:

• There is no requirement for each radio signal from a hub to be strong enough to reach the edge of the network. This means that each node does not need to send a strong signal to each hub, which is a big advantage for IoT applications where size and power are constrained.

• All nodes in the network can communicate directly with each other without the intervention of a gateway. This reduces latency and gateway burden.

• When objects block radio signal transmission, the hub node’s point-to-point connections can bypass the obstacles so no node is isolated.
