Assessment of Alternative Future Federal Land Mobile Radio Systems
This report evaluates the efficiency of federal spectrum use, performing a study that compares the spectrum resources used by several alternative land mobile radio (LMR) system architectures employing trunked radio technology to the spectrum resources used by the current conventional LMR systems. This study considered the 162-174 MHz federal LMR band in the Washington, D.C. area. The Washington, D.C. area was selected because it represents a spectrally congested environment and the 162-174 MHz band because it represents the most heavily used federal land mobile frequency band.
Description of a model to compute the aggregate interference from radio local area networks employing dynamic frequency selection to radars operating in the 5 GHZ frequency range.
This technical memorandum documents the analysis methodology that NTIA developed and used in assessing interference from radio local area networks to 5 GHz radar systems.
Correction Factors and Measurement Procedure to Assess the Interference Impact of Linear Swept Frequency Signals on Radio Receivers
This technical memorandum provides a methodology to determine the average and peak power level at the output of a filter with a linear swept frequency pulse train input to the filter. Using this method, peak and average power correction factors were developed that can be used compute the interference power level of a system that employs linear swept frequency signals.
