There are two main operating frequencies of wireless Bridges, 4G and 8G, and the characteristics of the two Bridges are different. In general, 4G wireless bridge is the current mainstream frequency band, good compatibility, good diffraction ability, but the anti-interference is relatively poor, especially in the urban area is vulnerable to wireless signal interference transmitted by other WiFi devices. 8G channel is relatively pure, anti-interference ability is better, the transmission distance is long, but the diffraction ability is poor.
refers to different wireless 4g: work on the worldwide free application ISM channel 2400M-248Within a 3M range. Wireless 8g: An open ISM band with a higher frequency than 4GHz. Different functions Wireless 4g: to achieve automatic sweep function, a total of 50 working channels, can be used for 50 users at the same time in the same occasion at the same time, no user manual coordination, configuration channel.
Band Difference Wireless 4G: operates in the 2400MHz to 2483MHz range of the global ISM band that does not require application. Wireless 8G: refers to the open ISM band from 725GHz to 850GHz, with frequencies higher than 4GHz. Application Differences Wireless 4G:With automatic frequency scanning function, including 50 working channels, can support 50 users in the same place at the same time, no need to manually select channels.
must be the frequency is different 8G is much higher, which also leads to the hardware support he needs is higher. 2. Information carrying capacity, due to the higher frequency, it can carry more information than 4G. 4G is more used for bluetool zigbee and other personal networks (we usually say peak network) such as small data transmission or small networks.
Regarding the irrigation area, it is best to use mobile pumping equipment in the storage area of barrel oil products. Example: There is a more widely used in the field: GQB-200A7P.
One is: if every fire is fixed. Fixed gas detection equipment can be installed. For example: GQB-200A or 200A4D Another: the fire is fixed during the day, the next time it may change to a different place. In this case, you have to choose mobile gas detectionAlarm is on. A comparison used in chemical plants: GQB-200A7.
Yes, combustible gas detectors must be installed in fixed active fire areas. Combustible gas detector is a device used to detect the concentration of combustible gas in the air, which can find flammable gas leakage in time to avoid dangerous situations such as fire and explosion. The installation of a combustible gas detector in a fixed hot fire area can effectively ensure the safety of the staff.
