ABSTRACT:
A portable or notebook type computer communication interface that permits portable computers to be reliably used in a data processing network. The interface involves communication circuitry, special device inputs and power monitoring and charging. A flexible portable computer wireless time and frequency division network is formed using a time and frequency division multiplexed communication channel assignment feature that together with a wireless link establishes a unique direct communication channel between data processing devices on different levels with data packet type transmission security. The principle permits each portable computer in the network to communicate with any other and any and all can transmit and receive at the same time.
