Multi – Hop Technology
Multi -Hop technology solves various challengers of implementing a reliable wireless communication net work
Multi-hop wireless communication is a wireless network conveying data through a number of wireless communication devices in a “bucket-brigade” manner. Relaying paths are automatically switched to an alternative one when one section of the connection is weak. In the KWL40 , up to 100 child stations connect to a single parent station. The communications distance between stations can be up to 1 km , thus making it possible to construct a wireless network in a wide range.
