Abstract :
Techniques for measuring radiated and conducted emissions from direct sequence spread spectrum transmitters can be directly applied to compliance testing for broadband wireless telephone services. The example cited compares 47 CFR Part 15 spread spectrum transmitters operating in the 2400-2483.5 MHz the ISM band with 47 CFR Part 24 broadband PCS IS-95A code division multiple access transmitters. However, the techniques described will work equally well with any of the proposed third generation standards such as W-CDMA or CDMA 2000
