Title: The Innovative Contributions of Todd A. Pressley
Introduction
Todd A. Pressley is a notable inventor based in Superior, Colorado, with a focus on advancements in telecommunications technology. He holds a total of 3 patents that showcase his expertise and innovative spirit in the field.
Latest Patents
One of his latest patents is titled "System and method for inbound roaming in IP multimedia subsystem networks." This invention enables a User Equipment (UE) to roam to a visited IMS-based network from a home network lacking IMS infrastructure. The process involves the UE sending a SIP Registration message to an Intelligent Roaming Application Server (I-RAS) in the visited network. Although the I-RAS initially rejects the registration, it provides a temporary Tel URI for the UE to use in a subsequent registration attempt. This innovative method ensures seamless connectivity for users roaming across different networks.
Another significant patent by Pressley is related to "CDMA signal transmission control." This invention encompasses various functionalities, including decresting, in-band to out-of-band ratio (RIO), power control, and spectral shaping. Decresting reduces peaks in the CDMA signal, while RIO generates a ratio based on the signal strength of in-band versus out-of-band portions. Power control adjusts the gain of the CDMA signal, and spectral shaping attenuates in-band portions adjacent to corner frequencies. This technology can be implemented in CDMA base stations to enhance range and capacity.
