A method and system is disclosed for adjusting wireless access coverage based on backhaul capacity. A base station, such as a femtocell, will determine the capacity of its backhaul connection in the downlink direction. The base station will then adjust the power level of it forward link to help ensure that the forward-link data rate to an access terminal is approximately matched to the determined capacity of its backhaul connection. In an example embodiment, the base station will adjust the power level of its pilot until the access terminal is requesting a forward-link data rate commensurate with the downlink rate on the backhaul connection.

1. In a base station communicatively coupled with a wireless communication system by way of a backhaul connection, a method comprising: determining a capacity of the backhaul connection for transport of data communications; andadjusting a transmission power level on a first forward link of an air interface to a first access terminal based on the determined capacity,wherein the base station and the first access terminal are configured to operate according to a CDMA family of protocols, including at least 1 times radio transmission technology (1×-RTT) and evolution data optimized (EVDO),and wherein adjusting the transmission power level on the first forward link of an air interface to the first access terminal based on the determined capacity comprises:determining a supportable data rate to the base station over the backhaul connection based on the determined capacity; andsetting the transmission power on the first forward link to a tuned level that supports a forward-link data rate to the first access terminal commensurate with the supportable data rate by adjusting the transmission power level on the first forward link of the air interface until forward-link data rate control (DRC) messages received from the first access terminal correspond to a requested data rate that is within a predefined range about the supportable data rate. 2. The method of claim 1, wherein the base station is a femtocell configured to operate in the wireless communication system. 3. The method of claim 2, wherein the wireless communication system is configured to operate according to a CDMA family of protocols, including at least 1×-RTT and EVDO. 4. The method of claim 1, wherein the backhaul connection comprises packet-switched data transport. 5. The method of claim 1, wherein determining the capacity comprises: performing a data-rate test with a test server via the backhaul connection; anddetermining a supportable data rate to the base station over the backhaul connection based on the data-rate test. 6. The method of claim 1, wherein adjusting the transmission power level on the first forward link of the air interface comprises adjusting a power level of a pilot beacon transmitted by the base station. 7. The method of claim 1, further comprising adjusting a transmission power level on a second forward link of the air interface to a second access terminal based on the determined capacity. 8. A base station configured to be communicatively coupled with a wireless communication system by way of a backhaul connection, the base station comprising: one or more processors;memory accessible by the one or more processors; andmachine-language instructions stored in the memory that, upon execution by the one or more processors, cause the base station to carry out functions including:determining a capacity of the backhaul connection for transport of data communications, andadjusting a transmission power level on a first forward link of an air interface to a first access terminal based on the determined capacity,wherein the base station is further configured to communicate with the first access terminal according to a CDMA family of protocols, including at least 1 times radio transmission technology (1×-RTT) and evolution data optimized (EVDO),and wherein adjusting the transmission power level on the first forward link of an air interface to the first access terminal based on the determined capacity comprises:determining a supportable data rate to the base station over the backhaul connection based on the determined capacity; andsetting the transmission power on the first forward link to a tuned level that supports a forward-link data rate to the first access terminal commensurate with the supportable data rate by adjusting the transmission power level on the first forward link of the air interface until forward-link data rate control (DRC) messages received from the first access terminal correspond to a requested data rate that is within a predefined range about the supportable data rate. 9.
