The wireless video transmission equipment that can support the wireless network protocol is transmitted through wireless microwave, and the working frequency band is 2.4G and 5.8G. Wireless microwave transmission varies according to the transmission power, and the transmitted distance becomes unequal. Wireless microwave has multiple operating modes, which are divided into AP mode/relay mode/wireless client mode/wireless bridge (WDS).
As wireless technology develops more and more mature, wireless bridges have two major technical characteristics through microwave transmission:
Wireless video transmission equipment is through digital microwave communications and has two major technical characteristics:
1. The signal transmitted by wireless microwave is a unified digital stream that is multiplexed according to the position of the time slot, and has the nature of comprehensive transmission.
2. It uses microwave channels to transmit information, has a wide signal bandwidth, and can transmit a large amount of data signals. Since the microwave signal travels in a straight line, digital microwave communication (as well as analog microwave communication) can be set up at a distance of about 50 kilometers from the station. This makes it easier to build. Especially in hilly areas or other areas where geographical conditions are relatively poor, digital microwave communications have certain advantages. Flexible networking and transmission of large-capacity data are indispensable devices in many communication systems. Digital microwave communication is also an important aid. Communication means.
As a wireless bridge digital microwave communication equipment has strong ability in anti-jamming, especially in the field environment can quickly build monitoring systems, without considering the laying of the line. Can be used in large-scale enterprises, mining areas, oil fields, forests, farms, roads, transportation, ports, docks, communities, construction sites and other important places, wireless bridge is easy to install, plug and play, can save labor costs and post-maintenance It is also simple. Shenzhen Leian provides wireless bridges, wireless monitoring equipment, wireless video transmitters, and mobile image transmission systems throughout the year. Welcome the cooperation of the vast number of engineering companies, we will provide you with complete wireless transmission solutions and excellent after-sales service.
Titanium Dioxide
Soft, odorless, tasteless white powder with strong hiding and coloring power, melting point 1560 ~ 1580℃. Insoluble in water, dilute inorganic acid, organic solvent, oil, slightly soluble in alkali, soluble in concentrated sulfuric acid. It turns yellow when heated and white when cooled. Rutile type (R type) has a density of 4.26g/cm3 and a refractive index of 2.72. R titanium dioxide has the characteristics of good weather resistance, water resistance and not yellowing, but the whiteness is slightly worse. Anatase type (type A) has a density of 3.84g/cm3 and a refractive index of 2.55. Type A titanium dioxide has poor light resistance and is not resistant to weathering, but its whiteness is better. In recent years, it has been found that nano-scale ultrafine titanium dioxide (usually 10 ~ 50 nm) has semiconductor properties, high stability, high transparency, high activity and high dispersion, and no toxicity and color effect.
