Hardware Installation
Overview
Commissioning and testing of the network is mandatory before end users are allowed access.
Typically, some radio links will need to be optimised by antenna re-pointing and throughput
tests on all backhaul links will need to be completed and shown to operate reliably. Wireless
networks have the potential to be slightly less stable than wired networks, particularly when
operating in public spectrum, and therefore extended testing needs to be completed to ensure
that each link is operating to the best of its ability and within design considerations.

During commissioning it is quite common for devices to be rebooted and for upstream nodes
to be turned off in order to test redundancy, routing and network self-healing. For this reason
it is recommended that end users are not allowed access until the entire deployment is
complete and tested fully.

At boot-up, the INN establishes network connectivity with an INS server via radio contact with
another network radio (or Ethernet link if deployed with wired connectivity), and downloads its
configuration and boot-up files from the INS. In a remote network the Gateway Server
provides the default pathway to the INS. Each individual embedded radio begins operation
with the network parameters that were pre-configured in the INS database, specific to the
class of INN that is to be deployed at that site.

Antenna placement
Antennas that form backhaul links should be installed with clear line of site (LOS) between the
.source. and the .target. (parent and child radios within a wireless link, respectively) antennas

The term line of site can be defined as having a visible path between two points that is clear
of obstruction such as foliage, building material, land or any other substance other than air.

The distance between the two antennas dictates the size of the Fresnel zone around the LOS
path. The Fresnel zone must also be clear of obstructions to minimise attenuation on the link.

There must be at least 1 meters of vertical or horizontal separation (the more

channel as the antenna that you are installing, ensure that from the installation
site, you cannot pick up a strong signal from the existing radio. Generally the
2.4 GHz radios on any site should be set to have four channels of separation
between them and any other radio visible to them.
