A first waveguide to microstrip transition, the waveguide having a top, a bottom, a first sidewall, a second sidewall and a closed end. A first wastewater influent stream is mixed with an activated sludge biomass in an aerobic digestion zone, so that least a portion of the organic wastes in the first wastewater influent stream are digested by activated sludge biomass. The handoff occurs between dynamically loadable modules that wrap around the TCPIP stack located at a front-end node and a selected back-end web server. A device asks its parent PNC to become a child PNC when a newly turned on device acts as a temporary PNC and broadcasts an initiation beacon indicating that it looks for a child PNC. The passive fixation member may include a shocking coil. Source address validation, address screening, burst-size limit, class-of-service provisioning, maximum concurrent call connections in progress, bandwidth control, and call frequency rate limit are provided as exemplary features implemented in a presently preferred exemplary embodiment of the present invention.
