Methods and apparatuses for graphically indicating station efficiency and pseudo-dynamic error vector magnitude information for a network of wireless stations
First Claim
1. A method of monitoring a wireless network, the method comprising:
- establishing link between a first radio device and a second radio device;
periodically transmitting a plurality of sounding packets from the first radio device, wherein each of the plurality of sounding packets are transmitted in a different modulation type;
receiving at least some of the plurality of sounding packets at the second radio device;
determining estimated error vector magnitude (EVM) information based on a carrier-to-interference noise ratio from the received at least some of the plurality of sounding packets;
aggregating the determined estimated error vector magnitude information for a predetermined period of time; and
displaying an animated constellation diagram by generating pseudo-EVM data points based on the aggregated estimated error vector magnitude information, wherein the pseudo-EVM data points are determined within a standard deviation of the estimated error vector magnitude information.

Abstract
Methods and apparatuses providing a visual metric of the efficiency of a network of devices communicating through a wireless access point (AP). These apparatuses and methods may also determine and display pseudo-dynamic error vector magnitude (EVM) information for a network of wireless stations, including displaying a pseudo-dynamic constellation diagrams using EVM information. These methods and apparatuses may transmit a plurality of sounding packets from each of one or more radio devices different modulation types (e.g., BPSK, QPSK, 16QAM, 64QAM, 256QAM and 1024QAM), and receiving at least some of the sounding packets at a second radio device (e.g., an access point) and determining EVM information from the received sounding packets, and displaying (or providing for display) a constellation diagram including pseudo-dynamic EVM information that is a constrained approximation of actual EVM information.
