FCC ID: HSW-SEM2410 5.1 RF Safety Requirements to 2.1091 for Mobile Transmitters The unit under evaluation has various external antennas. Cirronet Corporation calculated the MPE emission values for a SEM2410 with each of the antennas. The maximum power density occurs when using the 24 dBi dish for fixed applications and with the 12 dBi omnidirectional for mobile applications. They used the formula shown in OET Bulletin 65 and calculated the minimum distance between antenna and unsuspecting user as 26.0 cm for fixed applications and 6.5 cm for mobile applications. Cirronet Corporation will sell the SEM2410 with one of the following antennas: Previously Approved Antennas as Listed in Original Submittal MANUFACTURERTYPE OF ANTENNAMODELGAIN dB ACE DipoleACE-2400NF 2 dBi Cushcraft Yagi PC2415-RTNF15 dBi Mobile Mark Omni-Directional OD6-2400-RTNC6 dBi Mobile Mark Omni-Directional OD12-2400PTA-RTNC12 dBi Mobile Mark Corner Reflector SCR14-2400PTA-RTNC14 dBi Mobile Mark Patch P7-2400RTNC7 dBi Cirronet Corporation.

Power Output The EUT’s maximum expected output power as shown in the original grant of certification (FCC ID: HSW-2410M) was Frequency of Fundamental (MHz) Measurement (dBm)* Measurement (Watt)* FCC Limit* (Watt) 2401.916.20.0411.0 2440.016.80.0471.0 2483.516.80.0471.0 * Measurement includes 0.3 dB for cable loss The maximum EIRP expected for fixed installations is with the +24 dBi gain parabolic dish antenna. This would yield and maximum EIRP of 16.8 dBm + 24 dBi = +40.8 dBm. The maximum EIRP expected for mobile installations is with the +12 dBi gain omnidirectional antenna. This would yield and maximum EIRP of 16.8 dBm + 12 dBi = +28.8 dBm. FCC ID: HSW-SEM2410 5.1 RF Safety Requirements to 2.1091 for Mobile Transmitters – Cont. Source Based Time Averaging Additionally, source based time averaging may be applied as the worse case transmit duty cycle is given as follows: Worst Case Transmit Duty Cycle for SEM2410 This factor was calculated by first determining the worst case scenario for system operation - worst case being defined as the scenario when the SEM2410 would be transmitting the longest period during a dwell. This worst case operating scenario is as follows: 1)point-to-point operation (only two units communicating with one another) 2)data flow is almost completely unidirectional (that is, one radio is relaying a large amount of data to the other radio with only synchronization data being passed back the other direction) 3)The amount of data being fed to the sending radio is exactly portioned out to fit the maximum packet size allowable (280 bytes). The radio cannot send more than 280 bytes on a single channel – additional data must be sent on the next hop. For this example, a remote unit is transferring a large data file to a base unit. The maximum transmit time by Remote on a single channel would be: = 280 bytes * 8 bits/byte * (1/460.8 Kbps) = 4.86 ms The minimum hop duration for this scenario would be 6.94 ms. This transmit pattern would continue on each channel and is considered repetitive. Therefore, for purposes of MPE, the transmission duty cycle correction factor is then calculated as: Duty cycle = (on time)/(total time) = 4.86/6.94 = 70.0 % This yields for a duty cycle correction of 10 log (0.70) = -1.5 dB. Therefore the maximum EIRP for fixed installations may be expected to be +40.8 dBm – 1.5 dB = +39.3 dBm Antilog(39.3 dBm/10) = 8511.4 mW The maximum EIRP for mobile installations may be expected to be +28.8 dBm – 1.5 dB = +27.3 dBm Antilog(27.3 dBm/10) = 537.0 mW 5.1 RF Safety Requirements to 2.1091 for Mobile Transmitters – Cont. FCC ID: HSW-SEM2410 MPE Calculations The limits for this unit (uncontrolled exposure) are 1.0 mW/cm 2 . Taking the RF Denisty Field Equation: S = (EIRP in mW)/(4πR 2 ) and solving for Distance R R = SQRT ((EIRP in mW)/(S4π)) Solving the above equation yields R (cm) = SQRT (8511.4(mw)/(1.0(mW/cm 2 )*4*π)) = 26.0 cm for fixed installations R (cm) = SQRT (537.0(mw)/(1.0(mW/cm 2 )*4*π)) = 6.5 cm for mobile installations Since the EUT is designed for mobile and fixed applications (where the expected separation distance between antenna and humans is greater than 20 cm or 2 m respectively), all manual instructions have specified 20 cm or 2 meters as appropriate for the types of antenna being used the minimum exposure distance.

Since this device is typically professionally installed, this application is being submitted to certify the entire device (under a new ID number) in order to eliminate the need for non-standard connectors as allowed by 15.203. The SEM2410 is an industrial wireless modem housed in an environmentally rugged enclosure. The circuitry inside the modem includes a modularly approved WIT2410 frequency hopping transceiver (HSW-2410M), interface, and power conditioning circuitry. The SEM-2410 connects to the host through a standard Ethernet 10/100BaseT connection. A DB-9 serial port cable that attaches directly to the faceplate of the device is used to program internal module. Power is provided through a custom power connector. An antenna connector is also provided at the front of the unit. More detailed explanations of the function and use of the SEM-2410 can be found in the SEM product guide. 1.2Related Submittal(s)/Grant(s) The modular transceiver contained in this device has been previously approved under FCC ID: HSW-2410M by the FCC on 10/6/99 for use with seven different ant…
