5. Network Applications

HiPR-900 is suited to a variety of point-to-point, point-to-multipoint, and complex topology applications.
This section gives an overview of some common configurations.
5.1

Operating Modes

Any HiPR-900 unit can be configured to operate in master, remote, or repeater mode.
Note: master and repeater operating modes are exclusive to the full-featured HiPR-900 version.
Within a HiPR network, one unit has to be configured as a master that the remotes synchronize to. It can
be any unit in a system but is normally the one considered the base unit for coverage and support reasons.
Selection of operating modes, IP forwarding modes as well as data delivery conditions is done using the
web browser.
Note:
Only one radio model is needed because any full-featured HiPR-900 unit can be configured for
bridge or router mode, router gateway (access point), remote station, or even as a combined
store-and-forward remote with a local drop.

5.1.1 Master mode (exclusive to the full-featured HiPR-900 version)

A unit in master mode is the RF network sync master, the HiPR-900 unit dedicated to controlling the
network to changing channels as per FCC 15.247 rules.

5.1.2 Remote mode

A unit in remote mode is a HiPR-900 unit that follows the master's lead for changing channels.

5.1.3 Repeater Mode (exclusive to the full-featured HiPR-900 version)

By setting a unit to repeater mode, it becomes possible to extend the coverage of a HiPR-900 network
without requiring back to back repeaters. A unit in repeater mode follows the master's lead for changing
channels and repeats sync for distant units. A unit in repeater mode acts as a remote that always repeats
sync, repeats directed traffic in router mode, and optionally repeats broadcast traffic.

IP Forwarding Modes

5.2.1 Bridge mode

Bridge mode provides for fast set-up. IP bridging allows for quick deployment of basic point-to-point and
point-to-multipoint networks with minimal configuration to all units on a same network. Bridge mode
carries ARP and is transparent to any IP-based or IP-encapsulated protocols. In Bridge mode, packets re-
ceived from the Ethernet interface of a unit are passed over the RF interface so that all other units in the
system can receive the packets. Although Bridge mode is simpler to configure, the router mode is more
efficient in filtering out unwanted traffic over the RF.

5.2.2 Router mode (exclusive to the full-featured HiPR-900 version)

Used in advanced networks, router mode enables OIP optimization for reduced overhead and improved
throughput, and supports more complex network topologies such as store-and-forward and multi-hop
links. In router mode, packets are routed from one unit to the other with the help of the IP routing tables
inside each unit.
