  • Patent number: 7126951
    Abstract: A system and method for deploying a network of wireless devices, including mobile terminals, wireless routers and a least one control console, within a three dimensional deployment area such as a building, so that communication, identification and position calculations of personnel, such as firefighters, using the mobile terminals can be achieved regardless of building structure. The wireless routers are deployed in a substantial vertical manner in staircases and elevator shafts of a building of interest, either in advance as part of a safety program or immediately upon arrival of firefighters or other team at the building during an emergency. The system and method according to the embodiment of the present invention described herein uses both TOF and RSSI between the mobile terminals and wireless routers to identify the floor numbers where firefighters are located and to track firefighter movements.
    Type: Grant

  • Patent number: 6728232
    Abstract: An system and method for handling broadcast network requests for auto-configuration and discovery of IP to MAC address mappings and gateway presence in wireless peer-to-peer ad-hoc routing networks. The significant portion of a node's IP address is calculated by applying a hashing function to the six-byte hardware (MAC) address. The significant portion is appended to routing advertisements, and thereby propagates passively to other network nodes. DHCP and ARP requests, as well as other broadcast type requests, are handled by the local network stack of a node, without requiring a broadcast transmission over the wireless channel.
