single-node-reboot
timeout-sec=15..20000
After power up, a radio attempts to get an RF link up with one or more radios. If a radio fails
to get a link up (or drops all existing links), it will perform a complete reset after the timeout
specified in this command.
This feature is useful if a command is issued remotely to a radio (over an existing RF link) and
the link drops as a consequence of the command. If that radio now has no other links up it
waits for the "single-node-reboot” and then perform a reset. As a result, the radio reverts to the
saved configuration, allowing it to reestablish the original link.
Examples:
> snr 60
time-division-duplex
sync-mode=off or auto
This parameter selects whether this radio participates in the negotiation of the heartbeat
synchronization to select a single source for the heartbeat. The default
auto mode is
recommended for most applications.
The off mode may be useful in situations where there is a variable and significant delay in the
local Ethernet connecting the several co-located radios. In that case the radios may not be able
to establish synchronization and you may get better results turning off the heartbeat protocol.
See section 2.3.3 for a detailed explanation of the synchronization between co-located radios.
cycle-period-ms= 10 or 20 or 30 or 40 (not yet available )
At this time this parameter is set at 20 ms and can not be modified.
The cycle period is the total TDD time consisting, at the hub, of the transmit interval followed
by the receive interval. Use shorter cycle periods to reduce the latency in the link and larger
values to increase the link capacity.
transmit-percent= auto or 10 or 20 or 30 or 40 or 50 or 60 or 70 or 80 or 90
This parameter is relevant at the hub node only. It specifies the percentage of the total cycle
period dedicated to RF transmissions. The remaining time is dedicated to receiving from the
remotes. You do not need to specify this parameter at the remotes; as they join the network
they will set their cycles to the complement of this value.
In auto mode the hub radio dynamically assigns a split based on the current traffic load in each
direction. This split may be different from cycle to cycle.
At very low RF speeds (0.25 and 0.5 Mbps) the radio will not allow you to select some of the
more asymmetric splits as they would result in packets that are too short to carry any
meaningful data.
Select fixed splits if you wish to co-locate multiple radios and avoid self-interference. Select
the
auto mode in a single point to multipoint network without co-located radios. See section
2.2.1 for a more detailed explanation of fixed versus auto tdd splits.
