Quality of Service (QoS): Quality of Service (QoS) is an empirical, relative gauge of communications in a
network derived by an algorithm which is balanced to minimize RF communications while finding the best
communications path. Quality of Service is determined by a “balance” of 4 parameters: Device Class
(application dependent: sensor, valve, actuator, gateway…), Remaining energy (no limit if powered by
mains), RSSI, Number of “attached” children.
Radio Transceiver Module (Radio Transmitter module): Also known as endpoint, a radio transmitter
device is attached to the water meter register and transmits vital information about the meter and
consumption characteristics.
Received Signal Strength Indication (RSSI): RSSI is a measurement of the received radio signal strength
(energy integral, not the quality).RSSI is generic radio receiver technology metric, which usually is invisible to
the user of device containing the receiver, but is directly known to users of wireless networking of IEEE
802.11 protocol family.
Time of Use (TOU) Pricing: A tariff method in which a given utility charges different rates based on usage
during different times of day.
Two Way Communications: Two-way communications is radio technology terms which refers to a device
which can both transmit and receive (a transceiver) information on demand.
Wake-up preamble: A wake-up sequence used by the radio transmitter module, which is sent prior to data,
as communication is initiated.
WaveBox: Elster AMCO specified collector, which has many forms of communication ability to the head end
computer, including WiFI, GPRS, and Ethernet.
Wavecell: Current Coronis Wavenis/cellular network gateway. Offers full 2-way communications for
automated monitoring and remote network administration.
Waveflow: Current Coronis Low-cost, battery powered utility meter monitor with ultra-long battery life.
Wavehub: Mini Network concentrator or dedicated repeater
WYSIWYG – “What You See Is What You Get”: An acronym for What You See Is What You Get, used in
computing to describe a system in which content during editing appears very similar to the final product. It is
commonly used for word processors, but has other applications, such as Web (HTML) authoring.
