Abstract

A performance indicator for wireless digital signal reception is disclosed. In particular, a method for indicating the reception quality of a wireless digital signal at an electronic device is disclosed. The method includes a series of steps, starting with a first step of receiving the wireless digital signal at the electronic device. In the next step, the wireless signal is demodulated. Then, an error rate associated with the digital data portion of the wireless signal is determined. In the next step, a quality level of reception of the wireless signal is indicated. Specifically, the quality level of reception is directly proportional to the error rate of the digital data portion of the signal.

Claims

1. A method of indicating reception performance of a wireless signal at a radio frequency peripheral component card of a computer system, said method comprising:

receiving said wireless signal at a wireless receiver of said radio frequency peripheral component card;

demodulating said wireless signal;

determining an error rate of a digital data portion of said wireless signal; and

indicating a quality level of reception of said wireless signal at said radio frequency peripheral component card based on said error rate using an indicator component of said radio frequency peripheral component card.

2. The method recited in claim 1 wherein said quality level of reception is indicated by a light emitting device.

3. The method recited in claim 1 further comprising:

linearly translating said error rate into said quality level.

4. The method recited in claim 1 wherein said error rate is a packet error rate.

5. The method recited in claim 4 wherein said packet error rate is determined by a cyclic redundancy code (CRC) algorithm.

6. The method recited in claim 4 wherein said packet error rate is determined by a forward error correction (FEC) algorithm.

7. The method recited in claim 1 wherein said quality level is linearly proportional to said error rate of said wireless signal.

8. The method recited in claim 1 further comprising:

adaptively updating said determining said error rate and said indicating said quality level.

9. The method recited in claim 1 further comprising:

recording a history of said quality level with respect to another variable;

identifying a maximum quality level; and

indicating when said quality level is at said maximum level.

10. The method recited in claim 1 further comprising:

providing feedback to control reception, said feedback related to said quality level of reception; and

adjusting said reception based on said feedback, thereby improving said quality level of said reception.

11. A radio frequency peripheral component card of a computer system for receiving a wireless signal, said radio frequency peripheral component card comprising:

a receiver;
