Abstract
A networked system for managing a physical intrusion detection/alarm includes a network of end nodes, e.g., sensor nodes including one or more constrained sensor nodes for sensing physical conditions, and a gateway to provide network connections for the constrained sensor nodes. The system also includes a range extender for connecting the one or more constrained sensor nodes to the gateway, with the range extender including first and second radios and corresponding processors to wirelessly communicate with the gateway and constrained nodes.
Claims18
An apparatus for use in a network that comprises an access point and an end node, the apparatus comprising:
- a first radio to wirelessly communicate with the access point;
- a second radio to wirelessly communicate with the end node;
- a first processor device programmed to control and process messages received from the first radio, the first processing device configured to determine whether the first radio is required to send data to the access point;
- a second processor device programmed to control and process messages received from the second radio, the second processing device configured to determine whether the second radio is required to send data to the end node;
- and
- wherein when either one of the first or second processor devices determines that respective radios are not required to send data, the determined one of the first or the second processor devices is configured to change which of the end node and the access point, the first and second radios and the first and second devices are configured to communicate with.

An apparatus comprising:
- a first radio to wirelessly communicate with an access point;
- a second radio to wirelessly communicate with an end node;
- a first antenna element coupled to a radio frequency (r.f.) input and output of the first radio;
- a first processor device programmed to control and process messages received from the first radio, the first processor device configured to determine whether the first radio is required to send data to the access point;
- a second antenna element coupled to a radio frequency (r.f.) input and output of the second radio;
- and
- a second processor device programmed to control and process messages received from the second radio, the second processor device configured to determine whether the second radio is required to send data to the end node
- wherein the apparatus is a range extender and when either of the first and second processor devices determines that respective radios are not required to send data, the determined one of the first or the second processor devices is configured to change which of the end node and the access point, the first and second radios and the first and second processor devices are configured to communicate with.
