1. Introduction
The ArKion UGM (Under Glass Module) is an ISM band 902 to 928 Mhz frequency hopping
transceiver module. There are two radio performance options for this module, a high
power module with RF output power between 26dbm and 30dbm and a low power
module with RF output power of between 10dbm and 16dbm. The modules are intended
to be installed in an off the shelf electric meter with an interface providing power and a
serial data connection to the UGM module.
The power supplied by the electric meter is an unregulated 9~15Vdc. The UGM low
power module employs a switching regulator to regulate the supply voltage to 5Vdc and
then a linear regulator for a local 3.3V supply. For the high power module, an AC to DC
universal switching power supply draws power directly from the AC mains connected to
the electric meter. The supply generates a regulated 5V. A linear regulator is used to
then create a local 3.3V
The serial port is a logic level asynchronous port with a TX and RX lines. All data is
buffered on the UGM module to/from the electric meter. The UGM interrogates the ANSI
C.12 register set in off the shelf solid-state electric meters from Landis + Gyr. It’s main
function is to obtain energy consumption, negative consumption, and voltage readings
for billing, distribution monitoring, fraud detection, and conservation purposes. Meter
reading interval is remotely settable. Information retrieved from the meters registers are
temporarily stored within the Smart Meters solid-state memory. On a specified interval,
the Smart Meter will automatically transmit this information to the ArKion AMI server via.
other meters or CCOM using the Radio Frequency (RF) network. The ArKion AMI server
analyzes and archives the readings.
The UGM uses SuperCapacitors to support transmission of power failure messages and to
maintain the time of day clock. The Smart Meter does not use any internal batteries
eliminating need for field service.
2. Supported Products
UGM high
UGM low Power
Note: High and low power refer to RF output power. low power is approximately +13dbm
and high power is +30dbm Max. Other than transmit power the operation of the two
radios is identical.
3. Product Block Diagram
The UGM module design contains 3 basic blocks, a processor & memory block, an RF
transceiver block, and for the high power version an RF Power amplifier block. Both of
the RF sections are isolated under their own RF shield.

4. Requirements for FCC
To ensure continuing adherence to FCC requirements for the UGM module used in various
Landis+Gry Focus meter forms all of the following requirements must be observed.
1) The antenna must be installed such that 20 cm is maintained between the
antenna and users. For laptop installations, the antenna must be installed to ensure
that the proper spacing is maintained in the event the users places the device in their
lap during use (i.e. positioning of antennas must be placed in the upper portion of the
UGM Manual
Rev 0.1 ArKion Systems – Confidential Page 3
LCD panel only to ensure 20 cm will be maintained if the user places the device in
their lap for use) and
2) The transmitter module may not be co-located with any other transmitter or
antenna.
3) The end user should NOT be provided any instructions on how to remove or install
the device.
As long as the 2 conditions above are met, further transmitter testing will not be
required. However, the OEM integrator is still responsible for testing their end-
product for any additional compliance requirements required with this module
installed (for example, digital device emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE: In the event that these conditions can not be met (for example
certain laptop configurations or co-location with another transmitter), then the FCC
authorization is no longer considered valid and the FCC ID can not be used on the
final product. In these circumstances, the OEM integrator will be responsible for re-
evaluating the end product (including the transmitter) and obtaining a separate FCC
authorization.
End Product Labeling
This transmitter module is authorized only for use in devices where the antenna may
be installed such that 20 cm may be maintained between the antenna and users (for
example access points, routers, wireless ASDL modems, certain laptop configurations,
and similar equipment). The final end product must be labeled in a visible area with
the following: "Contains TX FCC ID: SM6-UGM-L for UGM low powered and SM6-
UGM-H for UGM high powered.
RF Exposure Manual Information That Must be Included
The users manual for end users must include the following information in a prominent
location "IMPORTANT NOTE: To comply with FCC RF exposure compliance
requirements, the antenna used for this transmitter must be installed to provide a
separation distance of at least 20 cm from all persons and must not be co-located or
operating in conjunction with any other antenna or transmitter."
4.1 Product Identification
This label is affixed to the face of the SmartMeter meter. This allows the installer to
recognize if the product is high or low powered radio.
