As the M Wireless is a wireless and internet-connected solution, special attention has been given to issues related to the reliability and security of the system. In brief, a few principles have been followed in all aspects of the system:
- Encryption of communication. Wireless and wired communications are secured against eavesdropping and message injection with strong encryption.
- No single point of failure. Lighting control with switches will continue to work even if all gateways and many communications nodes are removed.
- Updateable. Any connected device must be updated occasionally to remain protected against new threats.
Communication between the gateway, cloud backend, and fleet management tools are secured with industry-standard SSL encryption, similar to used in the finance industry for mobile banking. Inside the wireless mesh network, the network is secured with a pre-shared network key, which is used to secure messages in the network. The initial messaging between the mesh network and a wireless switch can also be optionally encrypted.
