Weather is NO.1 to aircraft flight security!
“Doppler Weather Radar” is the most advanced weather radar in today world, its three-dimension chart makes observing personnel to view weather change within around 500 km scope plainly. It can monitor and alert beforehand large-scope precipitation such as typhoon, rainstorm and disaster and calamity weather such as thunder storm, cyclone, low level wind shear, overfall.To boost further airplane flight security and safety factor of departure and arrival to forecast weather information more precisely for airplane flight, capital airport weather department and Beijing weather bureau invested vast fund to install a set of mobile Doppler weather radar to provide necessary weather data for capital airport flight departure and arrival to assure airplane flight security!

 It is around 20km from Mobile radar to airport weather department center machine room, the distance is far away, as radar installation site is mobile and unfixed, wired system such as optical fiber can not be utilized. Wireless microwave transmission equipment is the only way, radar itself is high power radio equipment will interfere microwave transmission. Many communication equipments are also with high power will interfere equipment in Air Traffic Management Bureau, as air traffic management communication and radar communication are with priority level, therefore it is impossible to increase power to suppress frequency and avoid interference. Therefore the requirement to microwave transmission equipment is strict, the equipment must takes on long distance data transmission and anti-interference capability, and at the same time spurious-wave (Npower harmonic wave) must be small, can not interfere other communication equipment. As this system is so important that transmission link must be stable and reliable, to assure without interfere other communication equipments, after review to many aspects and repeated arguments and practical test evaluation, in the end numbers of international renowned brands were eliminated，the airport decides to adopt ANYKEY-BT9210+ series wireless transmission product with outstanding stability and anti-interference feature produced by Beijing Forward Electronic Technology Co.,Ltd.
Not long after project operates, on Jul 10 2004, Beijing encountered downfall once a decade, Forward equipment went through interference of super rainstorm and a variety of high power wireless electronic equipments with stable transmission. Dramatically performance! It guarantees airplane flight security by providing exact weather data for airport weather department! And it wins reliance from users!
Wireless transmission product of Beijing Forward Electronic Technology Co.,Ltd. once again win market praise by the superior quality after public security private network four level large project.
