NTIA Sees Better Computer Simulation as Key to Spectrum Management
NTIA’s Office of Spectrum Management and its Institute for Telecommunication Sciences are making “significant investments in computer simulation capabilities” with an eye on improving how spectrum is managed, Keith Gremban, institute director, blogged Tuesday. “As demand for spectrum for commercial…

use continues to grow, policymakers are exploring spectrum sharing as a way to expand capacity while still fulfilling the needs of federal agencies,” Gremban wrote. “This model can work only if rules are designed to maximize the value of spectrum resources without compromising the quality and reliability of telecommunications.” In current modeling, spectrum managers separate systems using distance and frequency, he said. “The amount of separation is determined by interference protection criteria (IPC), which can be estimated through analysis, measurement, or computer simulation,” he said. “Although the analytic method is fast it can also be highly inaccurate, making accurate and repeatable measurements difficult to obtain.” Computer simulation can be used “when measurements are not possible, especially when trying to assess a multitude of spectrum sharing scenarios,” he said.
