Table 55 RF Monitor Environment Columns (continued)

Column	Description
PHY Packet Errors	Number of frames received by the MAP radio that had
	physical layer errors on the active channel. These errors
	can indicate interference from a non-802.11 device.
Pkt Re-transmissions	Number of retransmitted packets sent from the client to
	the radio on the active channel. Retransmissions can
	indicate that the client is not receiving ACKs from the MAP
	radio.
Utilization	Number of multicast packets per second that a radio can
	send on a channel while continuously sending fixed size
	frames over a period of time. The number of packets that
	are successfully transmitted indicates how busy the
	channel is.

Using the RF Trends The RF Trends window shows current and past 802.11 statistics for
