RF Exposure Requirements
General information:
Device category: Fixed per description in Part 2.1091
Environment: Uncontrolled Exposure
Fixed devices that operate under Part 90 of this chapter are subject to routine environmental
evaluation for RF exposure prior to equipment authorization or use.
Antenna:
The transceiver is designed to be installed only in sites where the antenna installation sites are
outdoor fixed mounted locations. The manufacturer does not specify an antenna, but in fix
mounted antenna sites they typically have gains to 3 dBi.
This device has provisions for operation only as a fixed mounted device, or a fixed location.

Operating configuration and exposure conditions:
The base stations conducted output power is 10 Watts. In base station operation the duty
cycle can reach near 100 %. The manufacturer also markets this device only for occupation
use. But, some installations may not control exposure other than separation distance.
- A typical fixed installation consists of an antenna system with a coaxial cable of the type RG-
213U which has a loss of 1 dB for a length of 50 feet at VHF frequencies.
MPE Calculation:
The minimum separation distance is calculated as follows:
The limit for uncontrolled exposure environment below 300 MHz is f in 0.2 = mW/cm
