His work focuses on enhancing communication systems, particularly in environments that require precise timing and synchronization.
Latest Patents
One of Lehman's latest patents is titled "Enhanced holdover for synchronous networks employing packet switched network backhaul." This invention discloses systems and methods to maintain synchronous communications using a global positioning system (GPS) satellite, a primary communication unit, and a secondary communication unit. The primary unit contains a high-quality oscillator and operates a virtual model of a secondary oscillator located in the secondary unit. If the secondary unit loses its GPS signal, it enters a holdover state and notifies the primary unit, which then transmits synchronization data to maintain communication.
Another significant patent is "Common digitizing rate for multiple air interfaces for generic cell sites in cellular radio." This invention allows a basestation transceiver to address multiple air interface standards efficiently. By using a common digitizing rate, the invention reduces redundancy in radio frequency equipment, optimizing resource allocation for various air interface protocols.
