4. Device Application of wireless video data link
Use of CD30NMT-V2 can realize long-distance two-way wireless data
communication, point-to-point two-way communication, and
point-to-multi-point star networking two-way communication.In
point-to-multipoint communication, if the communication between the
two access nodes must be transferred through the central node, each
node is in the same wireless LAN, all access nodes and the central
node communication share the wireless working bandwidth, the device
will automatically distribute the system rate equally.
The data transmission from the central node to the access node is
called the downlink, and the data transmission from the access node
to the central node is called the uplink. In point-to-point or
point-to-multipoint communication, the downlink shares the wireless
operating bandwidth with the uplink. When the device is shipped,
the default setting is the ratio of the upstream rate to the
downstream rate = 4:1.
Therefore, if the device is used to transmit IP Camera video data,
the IP camera should be connected to the access node. The device
automatically adjusts the wireless transmission rate according to
the service data stream it carries, and the smaller the amount of
service data it carries, the farther the transmission distance will
be under the same conditions. Therefore, when using the device to
transmit IP Camera video data, the wireless transmission distance
can be improved by setting the appropriate reduction of the IP
Camera video encoding bitrate.
