When using the transmitter with a wireless LAN, try the following corrective actions if the
transmission rate drops, the connection is lost, or other problems occur.
When using the transmitter indoors, install the wireless LAN terminal in the room where
you are shooting.
Install the wireless LAN terminal higher than the transmitter.
Install the device in a place when the connection with the camera is not obstructed by
people or objects.
Install the device as close as possible to the camera. In particular, note that during
outdoor use in poor weather, rain may absorb radio waves and disrupt the connection.
If the transmission rate over a wireless LAN drops because of interference from the following
electronic devices, switching to a wired LAN can resolve the problem.
The transmitter communicates over wireless LANs via IEEE 802.11b/g/n and Bluetooth
using radio waves in the 2.4 GHz band. For this reason, the wireless LAN transmission
rate may drop if there are nearby microwave ovens, cordless telephones, microphones,
or similar devices operating on the same frequency band.
If a wireless LAN terminal on the same frequency band as the transmitter is used nearby,
the transmission rate of the wireless LAN may drop.
If multiple transmitters are connected to a single wireless LAN terminal, be careful not to
use redundant camera IP addresses.
Note that the transmission rate drops when multiple transmitters access a single wireless
LAN terminal.
To reduce radio wave interference when there are multiple wireless IEEE 802.11b/g/n
devices on the 2.4 GHz band, leave a gap of four channels between each wireless LAN
channel. For example, use channels 1, 6, and 11, channels 2, 7, and 12, or channels 3, 8,
and 13.
When IEEE 802.11a/n can be used (on the 5 GHz band), switch to IEEE 802.11a/n (on
the 5 GHz band) and specify a different channel.
Wireless LAN radio waves can be easily intercepted. For this reason, activating encrypted
communication in the wireless LAN terminal settings is recommended.
