What are the general interference issues associated with MB-OFDM based UWB system and what is FCC’s expectation?
FCC expects all UWB systems to behave in a way that they don’t emit harmful energy to other systems. FCC tests were performed at the time of the rulemaking process using pulse based UWB systems. However, since the days FCC performed such tests, the industry requirement for higher bitrates resulted in more sophisticated modulation schemes for longer range, better co-existence, better simultaneously operating picocells, etc. MB-OFDM alliance members have done extensive simulation and real life physical tests and concluded that the MB-OFDM based systems cause much less interference than FCC expects based on FCC tests performed using pulse based UWB systems.
