Latest Patents
One of his latest patents is titled "Locationing using differential phase measurements of IEEE 802.11 preambles." This invention describes a method and apparatus for locationing that utilizes differential phase measurements of IEEE 802.11 preambles. The process begins with providing a local clock synchronized with a reference clock, allowing multiple receivers to receive IEEE 802.11 packets from a transmitter. By determining the phase offset between the local clock and the nearest cycle of a preamble in the received packets, the transmitter can be accurately located.
Another significant patent is the "Radio network initialization method and apparatus." This invention outlines a packet data transmission system where remote units, such as hand-held data gathering devices, are initialized via spread spectrum RF communications. The system employs a network chipping sequence for normal communications and a universal chipping sequence for initialization. This ensures that even if the network chipping sequence is not set in the remote units, the initialization data can still be communicated effectively.
