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...

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...

What is the problem with antenna downtilting?
Jun，9 2019
To understand the problem and the level of difficulty, we need to look at how directive antennas affect cell size. The example site and calculation below offer clarification The planned antenna downtilt is 4 degrees; the inner cell radius can be calculated to 190 meters and the outer cell radius to 570 meters. If the antenna were misaligned by only 1 degree (antenna downtilt angle of 3 degrees, wh...
