Maximum transmission power in white spaces

A method comprising:

• receiving a location of a white space device;
• determining an original probability with which a primary receiver would operate correctly at the location, wherein the original probability is determined without taking interference due to the white space device into account;
• determining a maximum degradation to the original probability that the white space device may cause at the location, wherein the maximum degradation is based at least in part on an estimated signal quality of a primary system at the location;
• and
• determining a maximum transmission power for the white space device based on the maximum degradation.

A non-transitory computer readable medium encoded with a computer program executable by a processor to perform the following actions

• receiving a location of a white space device;
• determining an original probability with which a primary receiver would operate correctly at the location, wherein the original probability is determined without taking interference due to the white space device into account;
• determining a maximum degradation to the original probability that the white space device may cause at the location, wherein the maximum degradation is based at least in part on an estimated signal quality of a primary system at the location;
• and
• determining a maximum transmission power for the white space device based on the maximum degradation.

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to at least:
