The system for browsing objects in reality that enables a user to obtain information via a wireless browser-enabled device. The browser-enabled device includes a modulated laser that is directed toward target sensors located on or near objects for which information is sought by a user. The target sensors, in turn, relay information as well as information received from the modulated laser via Internet to a wireless network that serves the browser-enabled device of the user. Information concerning the object of interest is then relayed to the browser-enabled device allowing the user to view information concerning the object.

A method and apparatus for facilitating handoff from a network access point (NAP) that is arranged and constructed to provide service to a communications unit (CU) in a frequency hopped communications system. The operations that are performed are providing service between the CU and the NAP on a connection using a first frequency hopping pattern (FHP); determining that the connection is suitable for discontinuation based on RSSI or load; sending a first message including an ID for the NAP and schedule for the CU to neighboring NAPS, the message requesting assistance with the service on tho first FHP; and receiving a second message from a neighboring NAP, arranged and constructed to provide connections to CUs using a second FHP, the second message indicating that assistance can be provided by the neighboring NAP.

A communication system ( ) that includes base stations ( ) comprising selection circuitry ( ) is provided herein. The determination of a call anchoring base station (base station performing Code Division Multiple Access (CDMA) frame selection) is made based on the base station with a lowest mean work load. During communication with a remote unit ( ), frames received by non-call anchoring base stations ( ) are backhauled to a switch ( ). The switch ( ) then sidehauls the frames to the call anchoring base station ( ), where selection and call processing functions for the particular call takes place.

A properly modulated carrier signal exits transmission circuitry (,) and enters a first and a second mixer (,). The modulated carrier is mixed with a first and a second function by the first and the second mixers (,). The functions are generated by a first and a second signal generator (,). The mixed signals exit the mixers (,), and are amplified (via amplifiers,), to be radiated by an antenna (,). The antenna (,) comprises two orthogonal antenna elements (,), that are in close proximity with one another (although not in contact). One of the mixed signals is radiated on a first element (,), and the other mixed signal is radiated on the second element (,). The resulting signal transmitted from the antenna (,) is the original carrier signal having the plane of polarization constantly changing. Thus a reflected signal emitted an instance earlier cannot interfere with a wave currently emitted.

Method and apparatus for signal transmission within a wireless communication system

A communication system (,) that includes base stations (,) comprising selection circuitry (,) is provided herein. The determination of a call anchoring base station (base station performing Code Division Multiple Access (CDMA) frame selection) is made based on the base station with a lowest mean work load. During communication with a remote unit (,), frames received by non-call anchoring base stations (,) are backhauled to a switch (,). The switch (,) then sidehauls the frames to the call anchoring base station (,), where selection and call processing functions for the particular call takes place.

Frames received by base stations (base stations) (,) are assigned a frame-quality indicator (FQI) by the base station. FQI information for all frames received is continuously backhauled to a switch (,). The switch (,) sidehauls the FQI information to a call anchoring base station, where a determination of a base station with the best FQI for each frame takes place. Once the anchoring base station determines a base station with the best FQI for a particular frame, the anchoring base station sends a FORWARD_FRAME message to the base station with the best FQI, or, if the anchoring base station is the base station with the best FQI, nothing is sent to the other base stations. Once the FORWARD_FRAME message is received by a base station, the base station immediately forwards the frame (identified by the frame number) to the switch (,). The switch (,) then routes the selected frame accordingly.

A communication system (100) that includes base stations (103-109) comprising selection circuitry (207) is provided herein. The determination of a call anchoring base station (base station performing Code Division Multiple Access (CDMA) frame selection) is made based on the base station with a lowest mean work load. During communication with a remote unit (113), frames received by non-call anchoring base stations (105, 107) are backhauled to a switch (101). The switch (101) then sidehauls the frames to the call anchoring base station (103), where selection and call processing functions for the particular call takes place.

The present invention provides a method for evaluating a communication link between a first communication site and a second communication site. The first and second communication sites increment a sent counter and reset a received counter upon sending a message to the other communication site. Each communication site also increments a received counter and reset a sent counter upon receiving a message from the other communication site. When the sent counter exceeds a sent threshold, the communication system site sends an alert that the communication link is down. When the received counter exceeds a predetermined percentage of the other communication site's sent counter, the site sends a message to the other communication site to let the other communication system site know that it is still receiving messages.

A switch (101) performs distribution functions by distributing packets to base stations that were most recently heard from. More particularly, as a gateway (115) provides frames to the switch (101), the switch (101) distributes the frames to all base stations in communication with a remote unit (113). In order to determine the plurality of base stations requiring the frames, an identification of base stations (on a per-call basis) currently backhauling data to the switch (101) for the call is maintained. The switch (101) then distributes frames received from the gateway (115) to those base stations currently providing uplink frames to the switch (101) for the particular call.
