2. Before installation, it must be determined that all the wire boxes, switches and sockets are installed firmly and correctly;
3. Heavy-duty lamps and fans are strictly prohibited from being directly installed on the keel of the ceiling project;
4. Its model, rated voltage, rated power, etc. should be consistent with the design parameters;
5. The shape of modern lamps is antique, innovative and practical. No matter how it is matched, the shape of these three types of lamps should be pursued as much as possible in the overall selection;
6. The family with the living room can use some fashionable lamps in the living room, such as trigeminal chandeliers, floral wall lamps, multi-section rotating floor lamps and so on.

1. Why fiberglass antenna is not suitable for indoor use? A: Many people may have noticed that international brands such as Linksys or DLink typically use only 7dB, 5dB and 2dB antennas, while 9dB or higher gain indoor omnidirectional antennas are rarely seen in the market. As far as we know, the 7dB antenna has fully met the requirements of indoor use. The antenna above 7dB has been used. Due to the small Angle, it cannot give full play to its advantages. Therefore, we recommend using an omnidirectional antenna above 9dB for outdoor use. As for someone, it is good to say indoor wall effect, this statement is unable to prove, also need not believe too much. 2. Why are omnidirectional antennas and perpendicular angles called? A: Generally speaking, an omnidirectional antenna is an antenna with a horizontal radiation Angle of 360 degrees and a vertical sector. The Angle is usually around 6 ~ 15 degrees. The higher the gain, the smaller the vertical Angle. For example, the radiation Angle of the 9dB antenna can be about 14 degrees, while the radiation Angle of the FRP antenna can be about 8 degrees as the limit
