A wireless communication system network, including a plurality of wireless communication system apparatuses, for use on unlicensed frequency such as a Code Division Multi Access (CDMA) frequency wherein the apparatuses are able to accept one of a plurality of protocols and convert to a predetermined transmission protocol which by the use of code spread spectrum transmission is able either: to transmit the signal to a telehouse for receipt and interpretation of the code to resend to another apparatus by code spread spectrum transmission where it is received and selectively converted and outputted into a required one of a plurality of protocols; or to transmit and be received by one or more other apparatuses encoded with the same transmission code to form a virtual private network where the transmitted signal can be outputted into one of a plurality of protocols.
