EMISSIONS TEST REPORT FOR A LOW POWER TRANSMITTER I. GENERAL INFORMATION Requirement:Federal Communications Commissions Test Requirements: 15.205, 15.207, 15.209, 15.247 Applicant: Utilicom 323 Love Place Goleta, CA 93117 Product ID: FCC ID: LFO-WR2411 II. DESCRIPTION OF EQUIPMENT UNDER TEST (EUT) The 2411 is a direct sequence spread spectrum transceiver, operating in the 2400 - 2483.5 MHz band with diversity. Operation is half duplex (TDD), with a duty cycle of 50% (6 dB). Output power is variable from 0 dBm to 23 dBm. Channel center frequencies are in 2 MHz steps. Center frequency = 2400 + 2* Channel Number Lowest channel: Channel 5 ( 2410 MHz ) Highest channel: Channel 35 ( 2470 MHz ) Four modulation rates are available: 1 Mbps: DBPSK 2 Mbps: DQPSK 5.5 and 11 Mbps: CCK III. TEST LOCATION All emissions tests were performed at: Compliance Certification Services 571F Monterey Road Morgan Hill, CA 95037 2 T.N. Cokenias10 August 2001 EMC Consultant/Agent for Utilicom 3 TEST PROCEDURES Radiated Emissions Test Requirement: 15.205 Measurement Equipment Used: HP 8593EM Spectrum Analyzer HP 8449 Microwave pre-amplifier, 1-26.5 GHz EMCO 3115 Double Ridged Horn antenna, 1 - 18 GHz 1. The EUT was placed on a wooden table resting on a turntable on the open air test site. The search antenna was placed 3m from the EUT. The EUT antenna was mounted vertically as per normal installation. 2. The turntable was slowly rotated to locate the direction of maximum emission at each emission falling in the restricted bands of 15.205. 3. Radiated emissions were investigated for a LOW channel, a MID channel, and HIGH channel. Emissions were investigated to the 10 th harmonic. 4. Careful measurements were made at the restricted bands 2310-2390 MHz and 2483.5 – 2500 MHz for the LOW and HIGH channel respectively. The preamplifier was not used for these measurements. 5. Once maximum direction was determined, the search antenna was raised and lowered in both vertical and horizontal polarizations. The maximum readings so obtained are recorded in the data listed below. Test Results: Worst case results are presented. Refer to separate Excel spread sheet files. ChannelFrequency, MHz Low2412 Mid2450 High2462 Radiated emissions were performed for three different transmitter antennas at maximum input power to antenna.

The pre-amplifier was not used. For each EUT test configuration, the EUT was rotated and the search antenna raised and lowered to find the orientation for which maximum emissions occurred. EUT output power and operating channel were adjusted until emissions in the restricted bands were within limits for each antenna.

Paragraph 15.247(a)3(i) states Systems operating in the 2400-2483.5 MHz band that are used exclusively for fixed, point-to-point operations may employ transmitting antennas with directional gain greater than 6 dBi provided the maximum peak output power of the intentional radiator is reduced by 1 dB for every 3 dB that the directional gain of the antenna exceeds 6 dBi. NOTE: Radiated spurious and bandedge emissions tests were performed with radio set to operate at 11 Mbps. This was determined from preliminary tests to produce worst-case emissions levels. 7 AC Line Conducted Emissions Test Requirement: 15.107, 15.207 Measurement Equipment Used: Rohde & Schwarz EMI Receiver ESHS-20 Fischer Custom Communication LISN, FCC-LISN-50/250-25-2 Test Procedure 1. The EUT was placed on a wooden table 40 cm from a vertical ground plane and approximately 80 cm above the horizontal ground plane on the floor. The EUT was set to transmit normally. 2. Line conducted data was recorded for both NEUTRAL and HOT lines. Test Results Refer to attached graph. 8 9 Minimum 6 dB Bandwidth Test Requirement: 15.247(a)2 Measurement Equipment Used: HP 8593EM Spectrum Analyzer 6’ length low loss coaxial cable Test Procedures The EUT was configured on a test bench. The EUT was set for continuous operation (TDD function turned OFF) . Frequency was set to 2.45 GHz (LOW channel). While the transmitter broadcast a steady stream of digital data, the analyzer MAX HOLD function was used to capture the envelope of the transmission occupied bandwidth. The test was repeated at 2.462 GHz (MID channel) and at 2.474 GHz (HIGH channel). Test Results: Refer to attached spectrum analyzer charts. Data taken with RES BW of 100 kHz shows minimum 6 dB BW of 10.5 MHz. Minimum requirement: 500 kHz ChannelFrequen…
