Abstract: A communication system uses multiple communications links that may include a high latency/high bandwidth link using a fiber-optic cable configured to carry large volumes of data but having a high latency. The communications links may include a low latency/low bandwidth link using skywave propagation of radio waves and configured to carry smaller volumes of data with a lower latency. The low latency/low bandwidth link employs a transmitting antenna system where aspects such as antenna height, type of ground, and typography of the surrounding area at the transmitting site are adjusted to optimize the direction and angle of propagation. Controlling these and other aspects increases the predictability and reliability of the wireless link by managing the number of hops and skip distance between the transmitting and receiving antennas. The two communications links may be used together to coordinate various activities such as the buying and selling of financial instruments.

Abstract: A communications device including an array antenna assembly including a plurality of transmit chains, each with a transmit power amplifier, synchronously captures transmit power measurements for each power amplifier. A baseband transmitter in the communications device determines when a predetermined symbol in a protocol, e.g. a PSS SSB symbol, is to be transmitted and sends, e.g. via a SPI, a capture command to command each of the ADCs corresponding to the power amplifiers to synchronously capture a power measurement. Power measurements are captured at the boundary of the predetermined symbol, and the power measurements represent average transmit power levels corresponding to the symbol. The power measurements are communicated to the baseband transmitter which processes the data using calibration tables and taper information. Processed power measurements are compared to desired transmitter target levels and errors are determined. Based on the errors the gains of one or more TX chains are adjusted.
