8 Wireless Communication

The SmartBypass has the capability to communicate over a secure wireless Industrial, Scientific and Medical (ISM)

band. The ISM Secure Wireless Mesh is the communication network protocol based on Radio Frequency wireless

communication for between ground-based equipment and the SmartBypass. The SmartBypass support the 900

MHz band in the US. The SmartBypass uses a frequency-hopping spread-spectrum solution. It does not occupy a

single user-selectable-channel like, for example, WiFi does.
