Conducted and radiated emissions data has been collected, reduced, and analyzed within this report in accordance with measurement guidelines set forth in ANSI C63.4-1992 as outlined in Elliott Laboratories test procedures. The intentional radiator above has been tested in a simulated typical installation to demonstrate compliance with the relevant FCC performance and procedural standards. Final system data was gathered in a mode that tended to maximize emissions by varying orientation of EUT, orientation of power and I/O cabling, antenna search height, and antenna polarization. Every practical effort was made to perform an impartial test using approp…

Test Summary Run #1 - Channel Separation and Utilization {15.247(a) (1)} see test data log. Channel separation was measured and calculated to be 995.3KHz (79 channels in 78.6 MHz) The 20dB bandwidth was measured to be: Low Channel925 KHz Central Channel 958 KHz High Chennel942 KHz Run #1 - Output Power {15.247(b)} see test data log. Low Channel19.7 dBm Central Channel19.8 dBm High Chennel19.8 dBm Maximum output power was 19.8 dBm (0.096 Watts), meeting maximum permitted of 1 Watt.

Eng:Mark Briggs Objective:Final QualificationSite:SVOATS#2Contact:Pete Garcia Spec:FCC Part 15Page: 2 of 4Approved: Revision1.0 Equipment Under Test (EUT) General Description The EUT Symphony PCI Card is a wireless LAN adapter with a low power frequency hopping spread spectrum (FHSS) radio system operating in the 2400-2483.5 MHz band. The Symphony PCI Card uses 79 channels, each 1 MHz wide. The system hops over one of 15 pseudo random sequences. On the average, each channel is used equally. Please refer to "RANGELAN2 Frequency Hopping Theory of Operation" attached to this submission. (Note that confidentiality has been requested for the Theory of Operation exhibit) Normally, the EUT would be placed on a table top during operation. The EUT was, therefore, placed in this position during emissions testing to simulate the end user environment. The electrical rating of the EUT is 120/240 V, 50/60 Hz.

Proxim have a waiver from the FCC allowing this deviation. The channel separation exceeds the 20dB bandwidth and the 20dB bandwidth is less than 1MHz, therefore the unit complies. Channel occupancy was 395 mSeconds with the unit transmitting a packet size of 1500 with a 0mS delay (worst case). Each channel was used twice in a 60…
