Abstract

Claims (15)

1 . A method for providing connectivity information associated with two or more wireless stations, the method comprising:

receiving, from a spectrum analyzer at each of the wireless stations, a description of power in a plurality of frequencies at one or more times to determine an ambient noise floor for each frequency in the plurality of frequencies;

weighting each ambient noise floor by a weight factor specific to each frequency, wherein the weighting comprises determining an achievable data rate for each of the plurality of frequencies;

determining pseudo-error vector magnitude (EVM) data points based on sounding packets transmitted between the two or more wireless stations, wherein the pseudo-EVM data points are random valued data points within a constrained range of previously determined EVM data; and

displaying, on a graphical display, at least one of the weighted ambient noise floors and signal to noise data based on the pseudo-EVM.

2 . The method of claim 1 , wherein the sounding packets have a predetermined modulation type.

3 . The method of claim 1 , further comprising displaying, on the graphical display, a pseudo EVM histogram based on the determined pseudo-EVM data points.

4 . The method of claim 1 , further comprising:

determining a constellation diagram associated with the sounding packets, wherein the constellation diagram includes a cloud of pseudo-EVM points around ideal points; and

displaying, on the graphical display, the constellation diagram.

5 . The method of claim 1 , wherein the previously determined EVM data is based on a plurality of received sounding packets.

6 . The method of claim 1 , wherein the pseudo-EVM data points are constrained within a standard deviation of the previously determined EVM data.

7 . The method of claim 1 , wherein the achievable data rate is based on the ambient noise floor for each frequency in the plurality of frequencies and a carrier to interference noise ratio (CINR) associated with a channel frequency.

8 . The method of claim 6 , wherein the CINR is based, at least in part, on a received signal strength associated with the channel frequency.

9 . The method of claim 8 , wherein the CINR is based on a difference between the received signal strength and the ambient noise floor.
