Abstract
An access radio port is provided that includes means for spreading a payload data signal, extracted from an ATM packet, with a uniquely assigned orthogonal code, means for transmitting the spread payload data signal to one of a group of mobile subscriber terminals located within a microport cell of a wireless terrestrial network, and means for releasing the uniquely assigned orthogonal code. In another aspect, a mobile subscriber terminal, configured to be located within a microport cell of a terrestrial wireless network that interfaces with an access radio port, is provided. The mobile subscriber terminal includes means for receiving an assignment of a unique orthogonal code, means for spreading a payload data signal by the unique orthogonal code, means for modulating and forwarding the spread payload data signal to the access radio port, and means for releasing the assignment of the unique orthogonal code.
