Simultaneous Transmit and Receive (STAR)

SINGLE CHANNEL, FULL-DUPLEX, SINGLE ANTENNA WIRELESS COMMUNICATION

Photonic System Inc. (PSI) has created disruptive technology that enables single channel, full-duplex communications via a single antenna on any wireless device. Also referred to as a Simultaneous Transmit and Receive (STAR) on the same frequency channel, PSI’s technology could effectively double the capacity of any wireless communication network within the existing allocated RF spectrum while saving wireless service providers billions of dollars in spectrum licensing  and relocation fees.

First demonstrating this capability in 2009, PSI has now invented, developed and demonstrated STARbox™; a new radio front-end circuit (hardware that interfaces directly with the antenna) that provides high isolation between the transmit path and receive path inside any radio or wireless device.  Some of the advantages of PSI’s STARbox solution include:

  • Enables STAR capability through a single existing antenna

  • Compatible with worldwide network standards

  • Simple, easy to include in existing radio designs

  • Does not require precise spacing among multiple antennas to form nulls

  • Can be made backward compatible with existing wireless networks

  • Will be small and low cost
