| RF refers to radio frequency, actually it is radio frequency currency, an abbreviation of high frequency AC electromagnetic wave. For alternating current which change lower than 1000 times every second is called low frequent current, exceed 1000 times is called high frequent current, and RF is that kind of high frequent current. It is applying a kind of figure coding technology to expand tape signal frequency, to increase the sending bits quantity via coding operation, to expand the bandwidth, thus the signal density on band is reduced, and the ability of anti-electomagnetism disturbance and anti-clustering disturbance, the wireless data transmission will be more reliable, therefore RF technology is widely used in the field of wireless communication, and, can not be replaced. |
