Re: FCC ID:W6U19PAWS1MIMO Applicant:SOLiD, Inc. Correspondence Reference Number:182088/09/03/2014 Date 10/6/2014 Dear Tim, Please see below for how we believe each of the issues raised in your correspondence have been addressed. TCB has superseded older versions of test report, block diagram and operational description, please advise if you would like both old and new versions to be visible. Regards, Daniel Park / Mark Briggs UL Verification Services TCB Question 1We are not aware that uniform procedures have been established/specified for testing DAS boosters in configurations other than "Donor-side and server-side components generally need to be tested together as a system." Further, uniform test procedures similar as used herein have not been specified, i.e., with input frequencies from donor-side fed into the remote unit at frequencies not allocated nor licensable for the applicable radio service rules. FYI OET Lab will look into updating KDB publication(s) accordingly to facilitate uniform processing of future filings for similar devices. TCB please coordinate with agent/lab/applicant to arrange for updated exhibits as appropriate, then TCB please submit herein after processing consistent with 2.962(b) (i.e., per Guide 65) and 2.962(f) (i.e., per FCC rules and policies). Response: The TCB Process has been adhered to. Additional guidance was not deemed necessarybecause the current guidance does cover the operation and testing of this device. This device is a sub-assembly of a Commercial Industrial Booster base unit, operating as the Remote side of a DAS system. The testing has been performed as a part of theDAS system, with the input to this Remote Side being generated by the Donor side. The Frequency of this input is an Intermediate Frequency (IF) frequency and not a transmission frequency. It is understood that the test report is not absolutely clear about this IF frequency, so we have requested that the test report be updated to clearly state this fact. This module is the Remote Side portion of a professionally installed base unit, much like the Modular nature of most Network Base Station transmitters. No explicit guidance and/or endorsement had been obtained from FCC (via KDB inquiry and/or e-filing corresp. and/or direct email) related to test procedures. RF test reports and related exhibits had been updated. Question 2)At least for our local Adobe Acrobat XI and X packages, we get error message and figure not displayed for op. desc. pg. 9/9; please replace exhibit. Response: This is addressed in the Revised Operational Description on page 9 which has been uploaded to the filing. Question3)Consistent with 935210 D01 and D02 provisions, if not in filing already please amend to identify/describe typical and/or specific "ODU" and/or "OEU," also "BIU," used at host end of an overall booster system that includes "ROU" populated with "RDU" FCC ID W6U19PAWS1MIMO. Response: This is addressed in the Revised Operational Description which has been uploaded to the filing. Please advise if FCC is OK with TCB superseding prior versions. Question 4a)EMC/radio report includes: PCS Input: 2456.5 MHz-2521.5 MHz PCS Output: 1930 MHz-1995 MHz AWS Input: 2366.5 MHz-2411.5 MHz AWS Output: 2110 MHz-2155 MHz Given that "PCS" and "AWS" denote specific FCC radio services with specific allocated and licensable paired bands [24.229, 24.5, 24-E; 27.5(h),27.4, 27-L], the latter is misleading or even incorrect.Please revise all parts(sections) of test reports and other exhibits to describe these somehow other than "PCS Input" and "AWS Input." Response: PCS Input and AWS Output bands are “IF” bands. Thetest reports and Operational Description have been modified and uploaded to the filing. Question 4b)EMC/radio report at 3.2 includes "The EUT was operated in a manner representative of the typical usage of the equipment." Please amend to explain howthis testing with "off-channel" input signals and with "partial" signal path only are valid for compliance demonstration of the end-use overall host/remote booster system configuration. As part of description, please also address the 935210 items listed above. Response:. The test reports have been modified and uploaded to the filing. Question 4c)Please amend test setup photos, also system block diagrams, to clearly identify/show input and output RF connector test points, and as relative to normal end-use optical-unit RF port(s) on donor-side. Response: Please refer the revised Block Diagram. Question 5a)It is noted that for example the spec sheet from web for "SOLiD ALLIANCE MULTI-CARRIER DAS" AUG 2014 includes text: "ALLIANCE ROU (REMOTE OPTICAL UNIT) ... Accommodates SISO / MIMO / Public Safety Configurations" (http://www.solid.com/das-solutions/alliance-multi-carrier-das.html) (http://www.solid.com/media/ALLIANCE_3PG_081914.pdf) In reply herein please submit explanations, along with system block diagram, how those MIMO modes/operations are implemented with W6U19PAWS1MIMO when used in an overall booster system, i.e. along with associated BIU, ODU/OEU and associated RDU/ROU. Other background: Based on exhibits herein, as well as grantee's marketing info and similarity to equipment configurations in other B2I grants per the new framework established under FCC-13-21, compliance demonstration seems needed for reasonably expected end-use MIMO operations when this "RDU" is optionally used as part of a booster system along with same-band/same- frequency integral or connectable (add-on) remote unit(s) ["RDU," or "ROU"], and along with host unit(s) [ODU, OEU, BIU] and transport links that supportMIMO streams. Equipment authorization for such operations needs to address KDB pub. 662911 multi-port tests, along with associated technical information describing the end-to-end system configurations. Response: Grantee and Test Labhave been advised and told to correct any misrepresentations related toPublic Safety Configurations.Grantee hasadded the explanationinto theOperational De…

SPURIOUS AND HARMONIC EMISSION AT ANTENNA TERMINAL FCC Rules Test Requirement(s): § 2.1051 Measurements required: Spurious emissions at antenna terminals: The radio frequency voltage or powers generated within the equipment and appearing on a spurious frequency shall be checked at the equipment output terminals when properly loaded with a suitable artificial antenna. Curves or equivalent data shall show the magnitude of each harmonic and other spurious emission that can be detected when the equipment is operated under the conditions specified in § 2.1049 as appropriate. The magnitude of spurious emissions which are attenuated more than 20 dB below the permissible value need not be specified. § 24.238 Emission limitations for Broadband PCS equipment. The rules in this section govern the spectral characteristics of emissions in the Broadband Personal Communications Service. (a) Out of band emissions. The power of any emission outside of the authorized operating frequency ranges must be attenuated below the transmitting power (P) by a factor of at least 43 + 10 log(P) dB. (b) Measurement procedure. Compliance with these rules is based on the use of measurement instrumentation employing a resolution bandwidth of 1 MHz or greater. However, in the 1 MHz bands immediately outside and adjacent to the frequency block a resolution bandwidth of at least one percent of the emission bandwidth of the fundamental emission of the transmitter may be employed. A narrower resolution bandwidth is permitted in all cases to improve measurement accuracy provided the measured power is integrated over the full required measurement bandwidth ( i.e. 1 MHz or 1 percent of emission bandwidth, as specified). The emission bandwidth is defined as the width of the signal between two points, one below the carrier center frequency and one above the carrier center frequency, outside of which all emissions are attenuated at least 26 dB below the transmitter power. (c) Alternative out of band emission limit. Licensees in this service may establish an alternative out of band emission limit to be used at specified band edge(s) in specified geographical areas, in lieu of that set forth in this section, pursuant to a private contractual arrangement of all affected licensees and applicants. In this event, each party to such contract shall maintain a copy of the contract in their station files and disclose it to prospective assignees or transferees and, upon request, to the FCC. (d) Interference caused by out of band emissions. If any emission from a transmitter Report No.: HCT-R-1407-F034-3 MODEL: RDU 1900P/AWS-1 (MIMO)Page 48 of 110 F-01P-02-014 (Rev.00) HCT CO., LTD FCC ID: W6U1900PAWS1/ IC: 9354A-19PAWS1MIMO operating in this service results in interference to users of another radio service, the FCC may require a greater attenuation of that emission than specified in this section. § 27.53 Emission limits (h) For operations in the 1710–1755 MHz and 2110–2155 MHz bands, the power of any emission outside a licensee's frequency block shall be attenuated below the transmitter power (P) by at least 43 + 10 log 10 (P) dB. Test Procedures: A modulated carrier generated by the signal generator carrier was connected to either the Uplink or Downlink RF port at a maximum level as determined by the spectrum analyzer was connected to either the Uplink or Downlink port depending on the circuitry being measured. The spectrum was investigated from 9 kHz to the 26.5 GHz of the carrier. Test Results: The EUT complies with the requirements of this section. There were no detectable Spurious emissions for this EUT IC Rules Test Requirement(s): RSS-131 6.4 Spurious emissions of zone enhancers and translators shall be suppressed as much as possible. Spurious emissions shall be attenuated below the rated power of the enhancer by at least: 43 + 10 Log10(Prated in watts), or 70 dB, whichever is less stringent. Note: If the minimum standard is not met, check to see if the input signal generators have a high harmonic content. Test Procedures: RSS-131 4.4 4.4.1 Multi-channel Enhancer The spurious emissions of the equipment under test shall be measured using the two-tone method in section 4.3.1, with the two tones Po1 and Po2 set to the required levels. Using a spectrum analyser with a resolution bandwidth set at 100 kHz, search for spurious emissions from 30 MHz to at least 5 times the highest RF passband frequency. The search may omit the band that contains the test tones and intermodulation products. 4.4.2 Single channel Enhancer The enhancer shall be operated as described in section 4.3.2 during the search for spurious emissions. Using a spectrum analyser with a resolution bandwidth set at 100 kHz, search for spurious emissions from 30 MHz to at least 5 times the highest RF passband frequency. The search may omit the band that contains the input signal.
