ST5801 meet the IEEE 802.11a standard. 1-108Mbps provides data transfer rates, and be LAN or Internet network access can not be applied to a wired network expansion or coverage of business, school, or in remote areas. We can provide "point" and "multipoint" connections. To obtain further protection, bridges, and an Ethernet interface adapters have lightning protection. Data transmission optional --IEEE 802.11a, IEEE 802.11a turbo. Under IEEE 802.11a mode, supports data transfer 6-54Mbps, in IEEE 802.11a turbo mode, supports data transfer rates 12-108Mbps In the security settings, we offer two modes, one is "shared key" the other is "exclusive key." ST5801A used in large wireless transmission backbone, IP68 rated, operating temperature -30oC ~ 70oC. Actual wireless monitoring project application is 32 km away from the internal design of the automatic monitoring network run watchdog, can automatically handle network events, the network will not storm off the network because the network. Built-in support multicast video transmission capabilities to support tree branch processing agreement, avoid network loops, supports 1:00 to 16:00 transmission.

If the temperature is outside this range may cause wireless bridge does not work properly. n wind speed - this section wireless bridge work wind speed ranges: 0-90MPH, wind up to 125MPH also resistant too. Therefore, you must consider the known maximum wind and wind direction point of installation, and the installation point to have such: pole, column or the tower like the mounting bracket. n mine - this section wireless bridge product includes built-in lightning protection devices, but you must ensure that equipment, mounting bracket, cables are fully grounded. n transmission range - this subsection applies to the transmission range of wireless bridge long distances in the basic data mode, the transmission range of 0-28 km, in Turbo mode, the transmission range of 0-14 kilometers. n Rain - This section wireless bridge have rain function, prolonged heavy rains also did not affect the quality of the transmitted signal. But you may need to use an Ethernet interface sealing tape, once moisture into the interface will reduce the performance of the product does not work and even the bridge. Products and Annex A. ST5801A master / slave bridge B. CAT5 / 25M-RJ45 (PoE Cable) C. DC power supply / RJ45 (RJ45DI-48) D. N-Type to N-Type RG-400 / 1.5M Cable E . AC / DC power line (DC48V 1.37A) a typical application case: 12-point digital wireless monitoring program Project Description: This project total of 12 ball machine, due to the distance, wired the way is very difficult, and the cost is very high. The actual environment, the front-end point to the center is in a state of non-visual, and distance are more than 15km, there is the furthest 22km, and good high-frequency signal transmission characteristics must also accessibility. According to site investigation, we chose the middle of one of the highest buildings, the tip of each point can be seen this building, while monitoring center can also see this building. So we choose this point as an ideal wireless relay points. http://www.suntor.cn/Product.asp?BigClassName=42 brand of professional cameras: front camera selectable after SUNTOR We use ST8301F transferred to integrate tallest building, as shown by 5.8G digital wireless devices: wireless relay points The connection diagram is as follows: the control center on the TV due to the wall, so we added a wireless digital video decoding device in the center, particularly the connection is as follows:
