Wireless monitoring is one of the most widest application of
wireless network at present.In common situation,the monitored
points are distributed in many different places and far away from
the central control piont.The traditional wired network way is not
only for the high cost,but also for the river or mountains
barrier.At this time,the advantages of wireless network are
outstanding.The wireless bridge technology can connect many
monitored points with central control point and set up very fast,we
can establish wireless network link in the shortest time.If the
conditional is permitted,the wireless brige can support over 50km
bridging.With the development of wireless technology,wireless
transmission application is accepted by various kinds of fields.
Wireless monitoring technology has been used for modern residential
security,fire protection and other fields.Digital microwave
transmission of wireless monitoring compress the video
codes,modulated by digital microwave channels,and then transmit by
the antenna.The reception terminal is on contrary,antenna receive
signal,microwave despread,video uncompress,and then recover the
simulated video signal.
In wireless monitoring system,wireless network plays a role to
connect monitored points and monitoring center.It can connect the
remote monitoring points for video transmission.At the same
time,for the high requirements of video quality,how to guarantee
the high quality video is also the key technology which should be
solved in wireless network transmission.In addition,from the
project aspect,bridging equipments are installed outdoor,how to do
remote power-feeding and equipment management are the problems need
to be aware of.
