Abstract

The digital dividend has the goal to achieve a more efficient utilization of the UHF broadcasting bands by permitting access to cognitive radio devices. Thus, the conventional use of analog, narrow band devices by secondary users of the same frequency range is supressed. One traditional application of this type are common Professional Wireless Microphone Systems (PWMS). To maintain the production process of multimedia content with wireless audio technology, PWMS manufacturers and users are seeking for possible frequency and operation mode alternatives. Therefore, the propagation properties for typical PWMS applications, like concert halls, inside the UHF broadcasting bands and beyond have to be characterized. First steps for body worn devices were presented. This paper provides a statistical channel model for large concert halls from 800 MHz to 1800 MHz, based on an indoor, frequency domain measurement campaign in July 2009, covering the entire inner room of a local concert hall, usually used for a large variaty of music, sports and other events. After an introduction of the measurement setup and chosen RX location grid inside the hall, this paper suggests a simple method to extract quantity, amplitude and latency of clusterized multipath components in time domain and gives information about the corresponding probability distributions inside the entire hall to achieve a channel model with a large abstraction level.
