Set Hop Duration
This is the
ph
command and it sets the length of time the transceiver spends on each
frequency channel. A smaller value will allow the remote to lock on to the base
signal faster at system startup, and will generally decrease packet latency. A larger
value increases network capacity, due to decreased overhead in channel switching.
This Set Hop Duration value only needs to be set in the base which broadcasts the
parameter to all remotes. However, link time can be reduced if this value is also
programmed into the remotes, which use it as a starting value when scanning for the
base.
The speed at which the radio hops affects both latency and throughput. The faster the
radio hops, the shorter the latency but the lower the throughput. The minimum packet
length and packet timeout allow fixed-length packets of data to be transmitted on a
single hop without leaving data stuck in the radio’s transmit buffer.
NOTE: If the hop speed is too fast, there may not be time to send a long packet on a
single hop.
