Store and Forward Repeater
The Aprisa SR+ in Repeater mode is used to link remote radios to the base station when direct communication
is not possible due to terrain, distance, fade margin or other obstructions in the network. The following
example depicts a repeater on the hill top to allow communication between the base station and the remote
radios on the other side of hilly terrain.
Repeater Packet Forwarding
The Aprisa SR+ works in packet Store and Forward (S&F) for simple and low cost repeater network.
Repeater mode is available in both Access Request (AR) and Listen Before Send (LBS/CSMA) MAC operating
modes. It allows a radio in Repeater mode to store a received packet and retransmit it.
Single Hop
The Aprisa SR+ functionality allows repeaters in Bridge mode to forward Ethernet packets based on Repeater
Network Segment ID. The base station translates the destination MAC address to the Repeater Network
Segment ID. This improves repeater performance by forwarding the packet if the Repeater Network Segment
ID belongs to the repeater branch and discards the packet
if it doesn’t.
Router mode supports repeater packet forwarding based on IP destination address. This improves repeater
performance by forwarding the packet if the IP destination address belongs to the repeater branch and
discards the packet
if it doesn’t
Single Repeater Single Hop
The following example depicts an Aprisa SR+ single repeater single hop Store and Forward network.
