Table 48. Global RF Parameter Descriptions

Parameter	Explanation
Perform RFC1042/	Determines how the access point will handle the
DIX Conversion	conversion of RFC1042/DIX frames that are
	received on its radio ports.
	Check this check box if the frames that are
	received and have a protocol type equal to a
	value in the “RFC1042 types to pass through” list
	are forwarded without conversion. If the frame
	has a protocol type that is not found in the list, it
	will be converted to DIX format before it is
	forwarded.
	Clear this check box if the frames that are
	received are forwarded without conversion; that
	is, when a SNAP frame is received from a radio
	with an OUI (Organizationally Unique Identifier)
	equal to 000000, it will be forwarded without
	conversion.
S-UHF Rfp	Specifies the largest data frame that can be
Threshold	transmitted without reserving airtime. Air time is
(S-UHF radios	normally reserved to help prevent collisions with
	other transmitters; however, when the amount of
only)	data is small enough, sending the data may be
	more effective than creating the reservation.
S-UHF Frag Size	Specifies the largest data frame that can be
(S-UHF radios	transmitted without fragmentation. On certain
	radios, fragmentation does not occur unless the
only)	radio detects interference. Larger frame sizes can
	improve throughput on a reliable connection,
	while smaller frame sizes can improve throughput
	on a poor connection.
902 MHz Frag Size	Specifies the largest data frame that can be
(902 MHz radios	transmitted without fragmentation. On certain
	radios, fragmentation does not occur unless the
only)	radio detects interference. Larger frame sizes can
	improve throughput on a reliable connection,
	while smaller frame sizes can improve throughput
	on a poor connection.
