From: Mary Ann Weitnauer To: Doug Young Date: August 04, 2016 Subject: Request for Info - File #0537-EX-PL-2016 ---------------------------------------------------------------------------------------------------------------- Message: Justification for # of transmitters submitted: Reference #33405 In addition to evaluating the impact of propagation impairments, the applicant will also be evaluating the effects of self interference as a result of collisions resulting from many simultaneous tag transmissions when there are a large numbers of transmitters. Various methods of collision resolution will be tested such as different spreading codes, successive interference cancellation (SIC) (where SDR signal processing techniques are utilized to demodulate and remove interfering packets allowing additional packets to be demodulated), and multi-user Network MIMO (in which multiple receivers or gateways behave as multiple antennas in a large distributed array). Up to 200 transmitters will be used for these tests to evaluate interference mitigation in a realistic environment where transmitters are located where a wide variety of direct and reflected paths to the gateways occur. Since transmitters are simulating wireless sensor applications with infrequent transmissions, a large number are needed to generate sufficient interference.
