Abstract: A system for determining the location of a wireless mobile device with respect to an interconnected network of wireless transmission waveguides is disclosed. The interconnected network could be interconnected ducts of an HVAC system in a building. Multiple wireless probes are placed at multiple locations within the HVAC duct system (or similar interconnected network of waveguides). Each probe may detect a common signal from a wireless mobile device and independently preserve arrival time information of the detected signal, wherein the signal propagates to probes by way of a free-space path to an opening in one or another duct, and thereafter to the probes via one or another path through the interconnected ducts, which act as wireless transmission waveguides. By correlating timing information of a signal received at three or more probes, a location of the mobile wireless device may be determined by one or another form of triangulation.

Abstract: A method and system for normalizing various simulcasting nodes within a distributed antenna system (DAS) simulcast sector uses the simulcast sector's known fiber delays, the distance between the nodes, and its corresponding RF delays. The methodology includes adding calculated delays to the known fiber delays to normalize each node's delay. Each normalized node delay value is equal to the value of the fiber delay of the furthest node plus the respective RF delay distance from that node.

Abstract: A distributed antenna system for using distributed antennas provides for locating a plurality of distributed antennas on existing infrastructure such as existing utility poles, traffic lights/signals, streetlights, etc. Each of the distributed antennas is connected to a base station hotel using a fiber optic cable. The distributed antenna system allows users to access wireless services provided by a plurality of carriers and using a plurality of communication technologies using a truly shared network and without having to implement duplicative wireless infrastructure components.
