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.

An optical communications network including a plurality of optical network elements and a plurality of network management systems. Each of network management systems executes a framework application. A communications link couples at least one of the network management systems and at least one of the optical network elements. A memory device is accessible by the network management system. The network management system communicates with the optical network element to detect a hardware feature present at the optical network element. The network management system determines a feature application supporting the hardware feature that is not supported by the framework application. The network management system loads the feature application from the memory device to the framework application and executes the feature application to manage the optical network element.

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.

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.

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.

A connector backshell assembly for wires or coaxial cables is provided in which a body and a cover define a housing therefor. An internal support member is mounted within the housing in the form of a split support which secures the wires or cables therebetween. A connector is mounted to the housing at the forward end thereof, which connector electrically engages the wires or coaxial cables. An exit clamp member mounted to such body proximate the aft end thereof, which defines a wide exit window, is provided for further securing such wires or coaxial cables as they exit the housing to thus provide double conductive member support and strain relief where such conductive members engage the connector e. g. when the conductive member or members are bent or twisted relative to the connector backshell assembly.
