Model: Gridstream Series-5 IWR FCC ID: R7PIWRS5 IC: 5294A-IWRS5

General Information:
Applicant: Landis+Gyr Technology, Inc.
Device Category: Mobile
Environment: General Population/Uncontrolled Exposure

Technical Information:
Antenna Type: Omni-directional whip
Antenna Gain: 5.5dBi
Maximum Transmitter Conducted Power: 29.73 dBm, 939.72 mW
Maximum System EIRP: 35.23 dBm, 3334.26 mW
Exposure Conditions: Greater than 22 centimeters

MPE Calculation
2
The Power Density (mW/cm ) is calculated as follows:

PG
S=
4πR 2
Where:
S = power density (in appropriate units, e.g. mW/cm2)
P = power input to the antenna (in appropriate units, e.g., mW)
G = power gain of the antenna in the direction of interest relative to an isotropic radiator
R = distance to the center of radiation of the antenna (appropriate units, e.g., cm)

Installation Guidelines
The installation manual should contain text similar to the following advising how to install the equipment to
maintain compliance with the FCC RF exposure requirements:

RF Exposure
In accordance with FCC requirements of human exposure to radio frequency fields, the radiating element
shall be installed such that a minimum separation distance of 22 centimeters will be maintained.

Conclusion
This device complies with the MPE requirements by providing adequate separation between the device,
any radiating structure and the general population.
