Increasing Network Communication Capacity

 PDF Version

A system and method for increasing user communication paths on available, non-controlled channels without additional hardware.

The U.S. Navy seeks to commercialize U.S. Patent 7,301,959 (System and method for multiplying communications capacity on a time domain multiple access network using slave channeling). 


Currently, many communication channels go unused due to a lack of channel controllers, even during times of high call volume. A channel controller is transparent hardware and software that is needed to control and provide users access to communication channels. Adding capacity/accessing these unused channels requires purchasing the controller equipment, and acquiring the real estate and support personnel to house, run, and maintain them. Opening user communication paths on these unused channels without the need for additional controllers would eliminate the additional costs currently needed to increase the volume of calls a communication system can support.   

The Technology

SSC Pacific has developed a novel communication method and system that takes advantage of available channels previously unused due to the lack of ground channel controllers. When an individual places a call, he or she is assigned a home channel by the controller. From there, modified controller software uses multi-channel networking to automatically send data through available unused slave channels while the user continues to seamlessly communicate. For example, the user may be connected to the home channel for voice, but streaming video and data on additional slave channels. The user is unaware that this process occurs, and continues communicating and receiving information. This system is unique in that it significantly increases a communication system’s capacity by utilizing unused channels without the cost of additional controllers and personnel.
