Abstract: A system includes a fire hydrant; a gain antenna operatively connected to the fire hydrant; at least one battery operatively connected to the fire hydrant; and a radio repeater operatively connected to the fire hydrant. The gain antenna includes any of a vertical monopole and a dipole antenna. The battery may include a lithium thionyl battery. The battery powers the radio repeater. The radio repeater includes a microprocessor; a memory component; and a radio transceiver. The system may further include a non-metallic enclosure that houses the radio repeater. The gain antenna may be operatively connected to the radio repeater inside the non-metallic enclosure. The radio repeater may further include an electronic voltage reference source that provides a stable voltage reference level that is lower than a lowest battery operating voltage of the at least one battery.

Abstract: A method of operating a wireless mesh network comprises generating a pseudorandom sequence element in a transmitting device and a receiving device of the network using information shared by the transmitting and receiving devices. The pseudorandom sequence element is then used to calculate a communication channel/timeslot assignment for communication between the transmitting wireless device and the receiving wireless device.

Abstract: A system and method for routing in a wireless mesh network providing a first device, which includes a first device transceiver, a first device memory unit that includes a first device first queue, a first device second queue and a first device table of neighboring devices, and a first device central processing unit. Such a system also includes a second device that includes a second device transceiver, a second device memory unit that includes a second device first queue, a second device second queue and a second device table of neighboring devices, and a second device central processing unit.

Abstract: A system for synchronizing time amongst a plurality of wireless network devices in a wireless network is provided, where a message is exchanged between a transmitting wireless device and a receiving wireless device. Such a system includes: a controller that inserts synchronized time information in the message, prior to transmitting the message, the synchronized time information comprising a current time value and a synchronization time value; and a processor that determines a local elapsed time value since last receiving a last synchronized time.

Abstract: File distribution in wireless mesh networks of devices interconnected in the wireless communications network including a gateway device and a remote device. The gateway device may include gateway storage unit with enumerated storage blocks, together forming the file, a transmitter transmitting the enumerated storage blocks from the storage unit. The remote device may include a storage unit with allocated storage block divided into enumerated storage blocks, a first bitmap mapped to the enumerated storage blocks, a receiver receiving an enumerated block and a processing unit for correlating the received enumerated block to a correlated enumerated storage block and correlating an enumerated storage block with a correlated stored bit in the first bitmap, setting the correlated stored bit in the first bitmap, storing the received enumerated block, building a list of missing blocks, and adding to a missing blocks list, and a transmitter transmitting the missing blocks list.

Abstract: A system and method of wireless communication. An activator comprises a first radio that transmits an activation message; a first microprocessor; a first memory component; and a first timer. A remote device comprises a second radio that periodically enters into an activation period of operation and a de-activation period of operation in order to conserve power; a second microprocessor; a second memory component; and a second timer. The first radio transmits the activation message repeatedly and continuously for a period at least equal to the sum of the activation period of operation and the de-activation period of operation of the second radio. At least one complete activation message is transmitted by the activator during every period of time allotted for activation of the second radio. The second radio increases a frequency of activation of the second radio upon receipt of a designated activation message from the first radio.
