Remote radio spectrum information acquisition
First Claim
1. A computer-implemented apparatus for collecting traffic related information using a plurality of scanners, each scanner including an audio signal output, the apparatus comprising:
- (a) a plurality of processing units, each processing unit being associated with a scanner, each processing unit receiving an audio signal output of a scanner and preparing the audio signal for transmission over a network by encoding the audio signal output of the scanner to digitally encoded audio, the audio signal output including traffic related information, wherein at least some of the processing units and their associated scanners are in locations remote from one another, each processing unit also receiving signals for real-time control of scanner operations;
(b) a scanner workstation physically remote from the processing units and the scanners, the scanner workstation including an application for receiving the digitally encoded audio and decoding the digitally encoded audio to reproduce the audio signal output of the scanners, and for remotely controlling scanner operations in real-time; and
(c) a transport network having at least two edge nodes, the transport network being in communication at one edge node with the processing units to receive the digitally encoded audio and being in communication at the other edge node with the scanner workstation to provide the digitally encoded audio to the scanner workstation in real-time, or in near real-time, and without buffering of the digitally encoded audio, and to allow scanner operations to be remotely controlled in real-time.

Abstract
A scanner system provides real-time remote acquisition of a scanner'"'"'s audio signals and visual display, and real-time remote control of scanner operations, including settings and functions. The scanner system may be used to gather information in a regional market by listening to geographically distant broadcasts available on radio spectrum frequencies. By synchronizing multi-spectrum monitoring, audio delivery, visual cueing, and control of spectrum reception, geographically independent persons can process scanner information as if they were physically present in the market. Thus, operators can gather information from public agencies and radio broadcasts from a remote market as if they were present in the market. The scanner audio signals may be used to produce traffic reports.
