From: Joe Dichoso [email protected] FCC Application Processing Branch Re: FCC ID HSW-HN1510 Applicant: Cirronet Correspondence Reference Number: 23623 731 Confirmation Number: EA967554 For Questions 1 – 4, see theory of operation from original radio specifications uploaded. If this does not address all issues, please let us know. 1) The transmitter cannot coordinate its hopping sequence with the hopping sequence of other transmitters, or vice versa, for the purpose of avoiding the simultaneous occupancy of individual hopping frequencies by multiple transmitters. Provide a description on how the device complies with this rule. 2) The system shall hop to channel frequencies that are selected at the system hopping rate from a pseudorandomly ordered list of hopping frequencies. Indicate how the pseudorandom hopping sequence is derived. Provide a list of channel frequencies and a sample of a few sequences. 3) Each frequency must be used equally on the average by each transmitter. Each new transmission cannot start on the same point in a sequence(except for voice systems.) Some transmissions may need only a few frequency hops to be completed and If the transmission started on the same frequency each time, this frequency would be used more than the others if many short transmissions were sent. Therefore, Describe where the next transmission starts when a sequence is not completed in a previous message. 4) Section 15.247(a)1 indicates that the system receivers shall have input bandwidths that match the hopping channel bandwidths of their corresponding transmitters and shall shift frequencies in synchronization with the transmitted signals. Please explain how the device complies with this rule when a packet is repeated or when multiple packets are sent. What is the receiver input bandwidth? How does the receiver shift frequencies and determine which frequency to shift to in order to synchronize with this transmitter? 5) Which antennas will be for fixed operation? Which antennas will be for mobile operation? The technical description indicates for indoor use. Clarify which antennas will be for indoor use. See new manual provided (pages 2 & 3) 6) Provide a complete manual with warnings. See new manual provided.

FCC ID: HSW-HN1510 SECTION 8 RF EXPOSURE INFORMATION FCC ID: HSW-HN1510 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 HN1510 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 HN1510 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-HN1510 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 HN1510 This factor was calculated by first determining the worst case scenario for system operation - worst case being defined as the scenario when the HN1510 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-HN1510 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.
