SSR’s as Repeaters
• This system works best if either the packets are small or if modules can be
configured with retries (ATRR) to overcome any interference the module may
cause between them.
• Multiple streaming repeaters can be cascaded to extend the reach even further,
each leg of the system should use a separate channel.
• Data travels through the repeater fastest using this method. May be used to
transfer large files.
• A source radio can roam among several repeaters as long as the “module 1” in
each repeater uses a common channel, i.e. ATHP=0 for all “module 1”s.
Application Specific
Because SSR modules operate in a peer-to-peer mode (no module must be designated
a master of the network) a system designer can take advantage of flexible network
topologies. Devices attached to each of the modules can accept data received by the
attached module before using the same module to rebroadcast the data to a device
further away. SSR customers have deployed self configuring and self healing networks
by developing sophisticated algorithms that take advantage of this feature unique to SSR
modules.
Usage Guidelines
• Devices attached to the modules must have their own addressing capability and
either “store and forward” or routing capability.
• System designers may use a certain channel (ATHP) for discovery and configuring
the network while using other channels for extended communication. This technique
allows for more efficient data transfers while minimizing latency and interference.
