  • Publication number: 20010055954
    Abstract: A wireless home communications network is provided. A digital cordless telephone base unit serves as the hub of the network. The base unit implements a cordless telephone communications protocol incorporating multiple-access features. Telephone calls can be placed on the PSTN through the base unit with a cordless telephone handset. Various other digital electronic devices, such as a home computer, laptop computer, television appliance, portable display tablet, refrigerator with integrated digital display, and PDA, can also use a cordless telephone transceiver to establish wireless data communication links with the base unit. These digital electronic devices can utilize the communication links with the base unit for a variety of functions, including Internet access, email, and grocery list maintenance. Such devices may also include audio input and output capabilities, such that they can also be used for voice telephony via the PSTN.

  • Publication number: 20010053705
    Abstract: A communications system for cordlessly connecting a portable computer modem to a telephone line. The communications system includes a base transceiver unit and a remote transceiver unit. The base transceiver unit serves to provide a means for transmitting and receiving computer data to/from a distant computer carried over a hard-wired telephone line. The remote transceiver unit serves as a means for wirelessly transmitting and receiving computer data to/from the base transceiver unit. The base transceiver unit includes a charging bay portion, an electrical power cord, and a first antenna. The remote transceiver unit includes a second antenna and a telecommunications cable. The second antenna is communicatively connected to the remote transceiver unit for enabling the remote transceiver unit to wirelessly receive radio frequency signals. The telecommunication cable is communicatively connected to the remote transceiver unit for enabling the remote transceiver unit to communicate with a personal computer.

  • Patent number: 6240277
    Abstract: A fixed cellular system including a telephone unit, interface and a fixed cellular terminal is disclosed. A telephone unit enables the generation of a sequence of digits in response to a user input. The sequence of digits are forwarded to a system interface wherein a send command is attached to each digit generated by the telephone unit. The digits with attached send commands are forwarded to a fixed cellular terminal responsive to the send commands such that receipt of a send command delays initiation of calls to destinations associated with the sequence of digits for a predetermined period of time.
