Abstract: A wireless communications interface couples wireless service to conventional wireline phone appliances. In one embodiment, the wireless communications interface is connected to the phone appliances through existing phone jacks. This allows a user to place and receive calls over a wireless network using the existing wireline infrastructure in a building.

In a second embodiment, the wireless communications interface is directly connected to the phone appliances, bypassing the installed wireline infrastructure. In a third embodiment, both wireline and wireless service are operative, and the wireless communications interface may include logic arbitration to route multiple calls to multiple phone appliances.

Abstract: The present invention is a desktop speakerphone having a base-station and a detachable microphone pod. The base-station includes standard telephone components, as well as a wireless receiver and a housing for a detachable microphone pod. The detachable pod contains at least one microphone and a wireless transmitter. When the pod is attached to the base-station, and the conference mode of operation is activated, the pod microphone's audio signal goes directly to base-station audio circuitry via a wired connection. When the pod is detached and the conference mode activated, the pod microphone's audio signal now goes via the pod's wireless transmitter to the base-station's wireless receiver. This detached, wireless mode allows the microphone to be positioned anywhere in the room, thereby improving the quality of transmitted speech by increasing the speech-signal-to-room-noise ratio, and lessening the potential for room echo by reducing the acoustic coupling between base-station loudspeaker and pod microphone.

Such network connectivity is maintained even if various customers are covered by different power line networks or if one or more power lines in a network are unavailable to transmit data. More particularly, in order to bridge a gap in a power line network, one or more messages are extracted from a first node in a power line network and are then transmitted to a second node via free space transmission, illustratively wireless radio frequency (RF) transmission conforming to one or more of the 802.11a, b or g standards. When those messages are received at the second node, the message is injected back into the power line on the other side of a gap in power line coverage. This method of transmission backup will continue until power line connectivity is restore upon which the preferred method will be selected and used.

Abstract: When wireless binding or pairing is required, two wireless devices change from a normal broad wireless operating range to a reduced wireless operating range. The wireless devices then conduct binding or pairing operations in the reduced wireless range. This prevents other wireless devices in the same area from detecting the same reduced range binding signaling and inadvertently binding with the wrong devices. After the reduced range binding operations are completed, the wireless devices automatically switch back to the broader normal wireless operating range and use the exchanged binding information for conducting normal wireless communications. The reduced range pairing scheme creates a simple and intuitive technique for pairing wireless devices without requiring the user to press buttons or select devices from a list.

However, when the subscriber roams outside their subscribed-to zones they may be switched from the present local cordless services to conventional personal communications services and pay air time charges.

Abstract: System and method for the registration of a mobile part (MT, OA, HA) in a base station (BS) in a telecommunication system designed for wireless communication between a mobile part (MT, OA, HA) and a base station (BS. The base station and the mobile part are initially placed in an access standby state. Subsequently, a verification procedure determines a message exchange (MA) between the mobile part and the base station if the base station supports a voice-controlled registration and if the mobile part is theoretically connected to the base station. If the theoretical connection is determined, a user channel connection suitable for the transmission of voice data is established between the mobile part and the base station. The mobile part is then either registered in the base station, or the registration attempt is rejected.

Abstract: A method and apparatus to perform a real-time drift correction of a remote handset's local oscillator in a digital cordless telephone. The remote handset begins in a standby (sniff) mode. The remote handset periodically wakes from a sleep mode and goes into a normal link verification mode. Once in the link verification mode, the remote handset enters a time division duplexing (TDD) mode and attempts to establish a link with a base unit based on the timing of the TDD data frame. After the remote handset establishes a link with the base unit, the remote handset requests a security word from the base unit. Upon receiving the requested security word, the remote handset determines if the requested security word matches a security word of the remote handset. The remote handset implements a software frequency adjustment of its local oscillator. Once per frame, the remote handset enters a timing recovery state where the current state of the frame is compared with a previous state.
