Abstract

A communications system such as a local area data network is equipped with a plurality of access points each capable of emulating either a phone mated with a wireless headset, the wireless headset, or both and establishing a link between access points emulating the phone and the headset. When the phone is within range of an access point and the wireless headset moves out of range with the phone but within range of an access point, the access point within range of the phone emulates the headset, the access point within range of the headset emulates the phone, and a communications path is established (if necessary) between the access points. In this manner, the effective range of the headset with respect to the associated phone is extended beyond a distance limit for a wireless communications protocol, such as Bluetooth, employed for the headset and phone.

Claims

1. For use in a communications system, a system for extending the range of a wireless headset comprising:

a phone;

a wireless headset associated with said phone, said wireless headset capable of communicating directly with said phone utilizing a wireless communications protocol having a distance limit;

a communications system; and

a plurality of access points each coupled to said communications system at one of a plurality of dispersed locations, each access point capable of selectively

emulating said phone utilizing said communications protocol,

emulating said headset utilizing said communications protocol

communicating with said phone within said finite distance from said phone utilizing said communications protocol,

communicating with said headset within said finite distance from said headset utilizing said communications protocol, and

interfacing with said communications system,

wherein said access points are capable of selectively establishing a communications path within said communications system between an access point emulating said phone and an access point emulating said headset, if necessary, to provide communications between said phone and said headset when said phone and said headset are separated by a distance greater than said distance limit.
