Certification Exhibit FCC ID: R7PIWRS4 FCC Rule Part: 15.247 ACS Report Number: 09-0412.W03.11.A Manufacturer: Cellnet Technology Inc. Model: Gridstream DCIWR RF Exposure 5015 B.U. Bowman Drive Buford, GA 30518 USA Voice: 770-831-8048 Fax: 770-831-8598

Model: Gridstream DCIWR FCC ID: R7PIWRS4 General Information: Applicant: Cellnet Technology Inc. ACS Project: 09-0412 Device Category: Mobile Environment: General Population/Uncontrolled Exposure Technical Information: Antenna Type: Omnidirectional Dipole Antenna Gain: 5.5dBi Maximum Transmitter Conducted Power: 29.79 dBm, 953mW Maximum System EIRP: 35.29 dBm, 3381 mW Exposure Conditions: Greater than 22 centimeters MPE Calculation The Power Density (mW/cm2) is calculated as follows: PG S= 4R 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) MPE Calculator for Mobile Equipment Limits for General Population/Uncontrolled Exposure* Transmit Radio Power Radio Antenna Antenna Distance Power Density Frequency Power Density Limit Power Gain Gain (mW (cm) (mW/cm^2) (MHz) (dBm) (mW/Cm2) (mW) (dBi) eq.) 902.3 29.77 0.60 948.42 5.5 3.548 22 0.553 904 29.79 0.60 952.80 5.5 3.548 22 0.556 915 29.76 0.61 946.24 5.5 3.548 22 0.552 927.8 29.75 0.62 944.06 5.5 3.548 22 0.551 927.9 29.75 0.62 944.06 5.5 3.548 22 0.551 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.
