The EUT was placed on a wooden table. The search antenna was placed 3 ft from the EUT. The EUT antenna was mounted vertically as per normal installation. 2. The EUT was slowly rotated to locate the direction of maximum emission at each emission being measured. tel: 650 726 1263 fax: 650 726 1252 internet: [email protected] RadioLAN 140 15.249 page 10 of 11 pagesFCC ID: MCIP140 3. 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 Procedures 1. Antenna to EUT distance was decreased to approximately 4 inches. 2. The spectrum analyzer was set to display the entire 5725-5875 MHz frequency range. 3. The MAX HOLD and MARKER features of the analyzer were used to determine the occupied bandwidth of the signal. Test Results All out of band signals were at least 50 dB below the fundamental or else met the radiated requirements of 15.209.

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 in a normal mode. 2. Line conducted data was recorded for both NEUTRAL and HOT lines. Test Results Refer to attached graph MCI140 AC Line Cond. Radiated Emissions from ITE Portion of EUT Test Requirement: 15.101, 15.109 The EUT meets the requirements for a class A device. The classification is applicable to this product because it will be sold and used in an office network environment. A verification report will be sent to RadioLAN by the test laboratory. THOMAS N.
