摘要： A cordless modem comprises a radio pair interfaced to a standard data/fax modem which allows a user of a personal computer to wirelessly connect to a telephone line. One end of the radio pair is a remote unit interfaced to the modem contained within the PC while the other end is a base unit connected to a standard telephone wall jack. This arrangement allows the user the convenience and freedom of using a PC, laptop, personal digital assistant, etc., within several hundred feet of a phone jack without being encumbered by a cord. A warning alarm on the remote unit informs the user when the signal strength between the radio pair is below a threshold value. Additionally, the base unit may be equipped with two spatially separated antennas to help mitigate the effects of signal fading.
