likely you are to experience a decrease in their useable range. This is also relative to the
environment you are operating in and depending on the amount of 2.4Ghz devices that
are active at the time of use, your useable range may be less than the optimum distance.
If a complex setup is required or you want to use multiple RØDELink systems, we
strongly recommend testing your setup in the same active environment you intend to use
it. This will allow you to assess the signal strength surrounding you and any range
restrictions you’ll need to be aware of during operation.
When using multiple RØDELink kits you will also want to space the receivers apart for
optimal performance. This only needs to be a minimum of 10-15cm and typically will
only affect usage in congested RF environments as well as when larger transmitting
distances are required. Always make sure that your receivers (Rx) are orientated so that
the antennas are forward facing (when using the Rx-CAM this will occur naturally if the
kits are mounted via the provided cold shoe mount and the display is facing the camera
operator).
How does ‘Signal to Noise Ratio’ affect my RØDELink’s range?-
Take for example a small room with no people in it, you are trying to hold a conversation
with someone across the room, you’ll probably need to be standing within 4-5 meters of
that person for them to be able to hear you speaking at a normal level. Now, consider
being in the same room but instead filled with 20 people talking at once, you’ll need to be
much closer than a meter for that same person you were trying to hold a conversation
with to hear you speaking at normal level, reducing the distance between you.
Think of yourself as the transmitter, your friend the receiver, your speaking voice the
signal and all the other people speaking around you to be the ‘noise’. The greater the
‘noise’ level (other signals in the 2.4Ghz spectrum), the closer the ‘transmitter’ and
‘receiver’ will need to be to successfully communicate with each other.
Of course, there is technology that can help with the background noise. Each RØDELink
system transmits on two frequencies simultaneously and its series II 2.4Ghz technology is
constantly searching for and hopping between the strongest frequencies to transmit on,
ensuring the best possible communication between transmitter and receiver. However,
understanding that the 2.4Ghz ‘noise’ will affect the range which the RØDELink systems
can transmit will help ensure you allow for the best setup within your requirements.
How do I optimize my RØDELink’s range and performance?-
Understanding both the environment you are operating in as well as exactly what the
oppositional factors mean and how they might affect performance is key to optimising
your RØDELink setup.
1. The biggest impact on performance will of course be interference from other
devices in the area you intend to use your RØDELink system. Wi-Fi access points
are the most common interferer in the 2.4Ghz spectrum, so a simple way of
