Note that EDs can only route their signals to the receiver directly or through RF-‐IOMs and routers, and
not
through other battery powered devices
.
When planning a SonNet radio network, it is
strongly
recommended that the Sontay
®
SonNet Site Survey Kit
be used. This easy-‐to-‐use package allows installers to test signal strengths between locations required for
EDs and the receiver prior to installing the full system. It can also identify whether routers are needed to
ensure reliable communications between all devices on the network back to the receiver. This removes any
guesswork from planning a system and allows the installer to order exactly and only the devices required.

Network Planning Considerations
When planning a SonNet radio system, it is always worth considering the placement of routers, and should
be capable of handling the consequences of a router failing or being damaged.
Example:
Consider a network with a requirement for 16 EDs:
1.
At least one router is required, as
16 directly connected EDs will
exceed the maximum limit of 12
(see page 13). Four EDs will be
orphaned.
2.
A single router (R1) will work,
but gives no redundancy if the
router should fail.
