Lora system of intelligent well cover
Nov，15 2019
Lora system of intelligent well cover There is a popular saying about Urban Governance: sewer is the conscience of a city. In the city, there are all kinds of densely distributed pipe networks underground, which are used for sewage discharge, drainage, various pipeline laying, etc. In these pipe networks, a node is the well cover we can see, walking in the road, sidewalk, park, community, f...

From a professional point of view, what is the reason why 5G is faster than 4G network?
Oct，1 2019
From a professional point of view, what is the reason why5Gis faster than4Gnetwork? In fact, it is not "5Gis faster than4G", but "5Gis proposed to be faster than4G". Every generation of wireless communication after3Gwill put forward the target first, and then consider the system design and technology selection. Millimeter Wave (Upgraded Bandwidth) Advanced Beam Shaping (Enhanced Signal-to-Noise Ra...

Does the longer the antenna length
Sep，10 2019
Does the longer the antenna length, the better the signal it receives? Don't take it for granted, because the theory and practice prove that this statement is unscientific, and the optimal length of the antenna is actually one fourth of the wavelength. The length of the antenna is determined by the frequency of the transmitted and received signals, that is, the wavelength. When the length of the a...

What are Applications of antenna
Jul，26 2019
Everyone has seen many kinds of antennas, but why choose such antennas and why design them in this shape, do you know? Rod/whip antenna The rod/whip antenna is generally omnidirectional, i.e. it radiates uniformly at 360 degrees on the horizontal pattern, i.e. it has no directionality and generally has little gain. Such antenna applications are very common, and there are not many special requireme...

The fiberglass omni antenna application
Jul，15 2019
The use of Fiberglass radome antenna is becoming more and more extensive with the extensive application in the fields of sea, land, air and civil aviation. If the antenna is compared to the "eye" goggles on the "eye" line of the day, Fiberglass radome has a wide range of uses. The radome mainly plays a protective role. The main purpose is to protect the antenna or the whole system from the impact ...

What is the future wireless communication
Jun，26 2019
Simply put, it is impossible to take the high-frequency route at all. The frequency above5Gis totally useless, and the coverage is too small. Only one path can be called5Gif the multi-carrier system is based on LTE, at least more than three carriers. As for those who say 5G network system needs Gigabit level and blowing water, there is no practical application at present...
