Mesh Networks

Mesh Networks

Devices in a mesh network connect directly with one another, and pass signals like runners in a relay race. It is the opposite of a centralized network. The transmission range of an IoT device on a mesh network is anywhere from 30 feet to more than 300 feet.

Since mesh network devices can hand-off signals, they have an ability to connect thousands of sensors over a wide area, such as a city, and operate in concert. Mesh networks have the added ability of working around the failure of any individual device. Wireless mesh IoT protocols include the Z-Wave Alliance, the Zigbee Alliance, and Insteon, which also has an alliance of vendors. These protocols aren't directly interoperable, although there are workarounds via hubs (more on this later).

ZigBee is an open protocol, but its critics say that not all of its implementations are necessarily the same. ZigBee runs a certification to ensure standard deployments. Insteon and Z-Wave are proprietary, which may ensure standardization of implementation.
