Selecting the data rate of a wireless network link according to a measure of error vector magnitude |
摘要 |
An apparatus in a node of a wireless network for setting the data rate for sending data to a remote node, and a method for setting the data rate. The method includes receiving a packet from the remote node, determining a measure of signal quality for the received packet; and selecting the data rate for communicating to the remote node according to at least the determined signal quality. The measure of signal quality is a measure of the EVM of the received packet. One implementation conforms to one or more variants of the IEEE 802.11 standard that uses OFDM packets.
