radio. When the sending radio receives the CTS packet, it sends the data packet to the
receiving radio. The RTS and CTS packets contain a reservation time to notify other
radios that the medium is in use for a specified period of time. This helps to minimize
collisions.
While RTS/CTS adds overhead to the radio network, it is particularly useful for large
packets that take longer to resend after a collision occurs.
You may configure a Harmony 802.11b Access Point to always use RTS/CTS, never
use RTS/CTS, or use RTS/CTS for packets over a certain size.
For example, if the RTS/CTS Threshold is set to 1000 Bytes, then a sending radio will
use RTS/CTS before transmitting any packet 1000 Bytes or larger.
The RTS/CTS Threshold parameter supports a range between 0 and 1513 Bytes (which
is the largest Ethernet packet).
If set to 0, then a sending radio will use RTS/CTS before sending any packet. If set to
1513, then a sending radio will not use RTS/CTS for any packets except those that are
1513 Bytes.
