Abstract: PROBLEM TO BE SOLVED: To provide a cordless modem including a pair of radio units interfacing to a standard data/fax modem in order that the user of a personal computer can connect to a telephone line by radio. SOLUTION: One of the pair of the radio units 32 and 34 is set to be a remote unit 32 interfacing to a modem housed in a PC(personal computer) and the other is set to be a base station unit 34 connected to a standard wall telephone jack. By this solving way, a user obtains the convenience and freedom of using the PC, a lap top, a personal digital assistant(PDA), etc., within the range of 100 to 200m from the telephone jack without the interference of a code. When a signal intensity between one pair of the radio units 32 and 34 is not more than a prescribed threshold value, an alarm on the remote unit informs the user of it.

Abstract: The antenna is a hybrid microstrip and reflector antenna having a planar patch antenna mounted to an upper surface of an insulated planar substrate. The substrate is coupled to a ground plane by means of one or more insulated coupling means (4), so as to form an airgap (10) therebetween. A coaxial cable (13) connectable to a transceiver is coupled to the bottom surface of the ground plane (2) at the outer conductor thereof and the inner conductor is coupled to a feed pin (9) which passes through the ground plane and protrudes through the surface of the patch. The feed pin is secured to the patch by means of soldering.

Abstract: Company telephone memory stores call path menu data, communication module receives input signals via telephone network, and transmits call path menu data in response, and control device connected to memory and communication module regulates the operating mode. User telephone comprises user memory that stores downloaded call path menu data, microphone to receive input speech of user, loudspeaker providing audible output signals for user, keyboard for receiving alphanumeric inputs of user, user communication module, display or indication output module, and user control device that controls user device functions. User communication module and user control device transmit request signal call path display that company telephone questions to determine whether it has call path display. Keyboard and display/indicator or output module operate such that transmission of request signal call path display can be released and blocked selectively. A silent circuit control device is included, connected to user loudspeaker in order to switch the user loudspeaker call path menu data signal during reception silently. AN Independent claim is made for method of transmitting call path menu data of company to user.

Abstract: A CORDLESS MODEM COMPRISES A RADIO PAIR INTERFACED TO A STANDARD DATA/FAX MODEM (36) WHICH ALLOWS A USER OF A PERSONAL COMPUTER (30) TO WIRELESSLY CONNECT TO A TELEPHONE LINE. ONE END OF THE RADIO PAIR IS A REMOTE UNIT (32) INTERFACED TO THE MODEM CONTAINED WITHIN THE PC WHILE THE OTHER END IS A BASE UNIT (34) CONNECTED TO A STANDARD TELEPHONE WALL JACK (40, 90). '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 (61) 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 (70, 70') TO HELP MITIGATE THE EFFECTS OF SIGNAL FADING.
