antenna dbi
In electromagnetics, an antenna's power gain or simply gain is a key performance number which combines the antenna's directivity and electrical efficiency. In a transmitting antenna, the gain describes how well the antenna converts input power int, 天線功率db/dBi/dBm. 天線的功率以mW為基本單位。在無線網路，100mW就很大了，可以傳約1哩，一般是30~100mW。在戶外點對點的ap比較有可能超過100mW，如mesh network。而手機則是相對基地台的位置做調整，GSM900最大2W，GSM1800最大1W。 dB (decibels). 因為RF receiver可能收到 ..., 筆者去3C賣場時總會在天線區前面駐足許久，心想這些不同dBi的天線到底有沒有廠商宣稱可以加大訊號範圍的效果。剛好最近廠商送測品有5dBi的天線，加上原本家裡小小一根的1.8dBi天線，和編輯部裡某位大大購買的鄉民專用，30公分起跳的10dBi天線，這回就一起來比較看看。,What is ANTENNA GAIN?

It solves that by radiating energy more directionally than an idea antenna that radiates evenly in all directions (0 dBI). This increased signal strength of ,This tutorial uses the example of our solar system's sun and an imaginary mirror to illustrate the concept of antenna gain and directivity, with no math ! ,The concept of antenna gain is introduced. Gain is a product of the directivity and the efficiency of an antenna. , Gain is one of the most common measurements stated on antenna specification sheets. But you shouldn't judge an antenna by gain alone, especially if you're unclear on its true meaning. "Gain” and “decibel” have certain meanings when referring, An antenna is an electrical device that receives electrical current and converts it to a radio wave, used for transmitting and receiving voice and data. Antennas are made of conductive metals such as gold, silver, copper, aluminum and steel. They're
