摘要： Method and apparatus to provide a wireless tether system is described. In one embodiment, one or more wireless tether apparatuses are in wireless communication with one or more base units. A wireless tether apparatus may be configured such that when separated from a base unit greater than a predetermined distance, such a wireless tether apparatus provides information to the user of the wireless tether apparatus to aid a user such as a human, animal, or machine in finding their way back to a desired location. A predetermined distance may be configured to change over time to accommodate different tether distance requirements at different times, e.g., closer to a home location at night and further away from the home location during the day. In one aspect, wireless tether apparatuses and base units communicate using a plurality of different communication modes such that when one mode fails other modes are utilized to reestablish a connection therebetween. In another aspect of the present invention, a plurality of wireless tether apparatuses are wirelessly tethered together such that individual proximities are maintained but still allow a plurality of wireless tether apparatus users to move about in an expanded range. In one aspect, a wireless tether system is employed such that one or more wireless tether apparatuses may be dynamically assigned to a plurality of base stations to allow changes to wireless tether apparatus locations and distances. In another aspect, when wireless tether apparatuses leave a predetermined tether distance, one or more alerts may be broadcast from the wireless tether apparatuses indicative thereof to other wireless signal receivers in proximity thereto not normally used as wireless tether signal receivers Users are located to determine if the user is within, or has departed from at least one bounded area established about a geographic location. The bounded area may be defined by setting one or more distance boundaries from the geographic location. A base station may monitor the location of a wireless device in proximity of the user. If the wireless device departs from a bounded area, a message containing information configured to be understandable and convey meaning to the user and/or a third-party is sent to the wireless device and/or the third-party. For example, the message may be configured to communicate to the user and/or third-party information pertaining to the departure from the bounded area, location information, navigation directions, instructions, etc. The message sent may include text and/or other symbols.

摘要： Users are located to determine if the user is within, or has departed from, at least one bounded area established about a geographic location. The bounded area may be defined by setting one or more distance boundaries from the geographic location. A base station may monitor the location of a wireless device in proximity of the user. If the wireless device departs from a bounded area, a message containing information configured to be understandable and convey meaning to the user and/or a third-party is sent to the wireless device and/or the third-party. For example, the message may be configured to communicate to the user and/or third-party information pertaining to the departure from the bounded area, location information, navigation directions, instructions, etc. The message sent may include text and/or other symbols.
