PRODUCT DESCRIPTION

The Wall Meter Interface Unit1(Wall MIU1 or MIU1) by Schlumberger, is a compact

electronic device that collects meter reading data from an encoder register and transmits the

data for collection to a nearby line of sight CellNet MicroCell Controller(MCC) fixed

network. This product is based on CellNet BAMM RF design. This is a one way

transmission to MCC. Since the MIU can be mounted as much as 500 feet from the encoder

length/distance.), optimum broadcast signal strength is obtainable, insuring a high percentage

of accurate. The MIU also meets FCC regulations part 15.247, allowing higher output power

and greater range. The MIU uses direct sequence spread-spectrum technology to avoid RF

interference and enhance security.

¥ Protects utility liability by increasing meter reader safety.

¥Requires no field programming.

¥ Economizes manhours needed to collect and process meter reading

data, thereby increasing utility profits.

OPERATIONS OVERVIEW

The Wall MIU1 collects meter readings from the encoder register on an hourly basis and

transmits the information every fifteen minutes. This redundant transmit of the same data

four times an hour increases the greater reliability of the data to be received the fixed

network MCC.
