Configuration 26
Fragmentation
The Harmony 802.11a Access Point supports an optional feature called Fragmentation.
In harsh radio environments, 802.11a devices may have difficulty transmitting large
packets that exceed a certain size. However, when Fragmentation is enabled, the
802.11a Access Point can break up large packets into a number of smaller packets
(called "fragments") that can be successfully transmitted to another 802.11a device.
The receiving 802.11a device then reassembles the original packet once it has
received all of the fragments.
You can configure a Harmony 802.11a Access Point to never use Fragmentation or to
fragment only those packets that exceed a certain size. For example, if the
Fragmentation Threshold is set to 1000 Bytes, then a sending radio will fragment any
packet 1000 Bytes or larger before transmitting.
The Fragmentation Threshold supports a range between 256 and 2346 Bytes. If set to
256, then a sending radio will fragment all packets 256 Bytes or larger. If set to 2346,
then a sending radio will fragment only those radio packets that are 2346 Bytes or
larger.
By default, Fragmentation is always off.
Repeating
The Harmony 802.11a Access Point can repeat packets between 802.11a clients that
are associated with it. If your network requires that 802.11a clients communicate with
each other, then enable the Access Point's Repeating parameter. Otherwise, set
Repeating to disabled if you want to prevent 802.11a wireless clients from
communicating with each other.
