7.2 Deployment Planning
Although an Ambient network is built up from the GW outward, a deployment planning is built up
the other way around; starting from the SPs. As SPs have a shorter range than infrastructure nodes,
they determine the positions where infrastructure nodes should be placed. In order for SPs to
communicate with an MR, it needs to be in range of the MR.
Mark the locations on the sitemap that require network coverage, i.e. the locations where you want
to deploy SPs. SPs are deployed at those locations where you wish to measure environmental
parameters. If you are using the Real Time Location System (RTLS) functionality of the SPs, mark the
area where the SPs will need to be located.
Having the SPs marked down and the SP location area marked down, you can now use their typical
radio coverage to identify the areas where you need to place MRs. Draw circles around each SP. Use
as diameter typical value of 15 meter. Each SP should be in range of at least 1 MR or the GW, but
preferably more to ensure good connectivity. The areas on the map that are covered by several
circles are good locations to place MRs. As a rule of thumb, it is preferable for every SP to be in range
of at least 3 Infrastructure nodes. The SP has multiple paths to the gateway and there is enough
redundancy in case one router is congested or off-line due to whatever reason.
For larger sites it makes sense to perform some range tests prior to planning the installations.
Deployment tooling can be used for this purpose. Contact [e-mail] for more
information about deployment tools.
Ensure that every SP is always in range of at least 3-4 Infrastructure Nodes

to keep track of the deployed nodes. During the process of
planning your deployment, write down the unique ID of the GW/MR/SP and its respective location
on the map as well as a short description of the area in which it is placed, for example:

the AC outlet from the ceiling lighting
Now after having collected the maps and pictures and having marked all important locations on it,
we are ready to make a first Infrastructure deployment plan.
Start with placing the Gateway preferably somewhere in the centre of the environment; this is critical
to the structure of your network. If you place the Gateway at the centre of the network, you will have
less hop counts and thus less latency; if you place the Gateway at the corner of the network, you will
introduce higher hop counts and as a result have more latency and increased the probability of
creating bottlenecks.
Now, using the positions and areas of the SP, place an MR near an AC outlet in areas that are in
range of the SPs. On a separate map, place the MRs at exactly the same locations. Now try to make
an estimation whether the network is well connected by drawing circles around the MR based on
their typical radio range. Ensure that each MR is in range of at least 2 other MRs and that there is
