Abstract
A technique is disclosed that provides an improvement in how stations that operate in accordance with different protocols coexist in the same network without some of the costs and disadvantages of the prior art. The illustrative embodiment of the present invention provides protection against collisions due to transmissions in accordance with a first protocol (e.g., IEEE 802.11, etc.) occurring around the same time as transmissions in accordance with a second protocol (e.g., Bluetooth, etc.). Protection against collisions is achieved in the illustrative embodiment by a protecting station causing other stations (e.g., access points, etc.) to defer any pending first protocol transmissions during a predetermined time interval. The protecting station is then able to transmit in accordance with the second protocol during the predetermined time interval.
