Computing devices can be used to control communications by choosing frequency bands and / or frequencies in communications where long-distance HF radio wave communication physical limits or optimal delay in the vicinity can occur.ゴールディン, アレクシ...

High-frequency technology is an important part of 5G to an ultra-high speed connection at a data rate of 10 Gbps or even 20 Gbps to the mobile terminal. However, few research efforts had been made in the study of the radio propagation model for mobile network using high-frequency bands fr...
Source:Radio Communications, Chapter 1 In aviation we used to note our frequency as "Upper" or "Lower" to differentiate between the two. You would say, "transmitting 8060 upper," for example. All aircraft HF communication, outside of the military, seems to have gravitated to the upper sideb...

A theory is developed to understand the generation mechanism of thunderstorm high-frequency radio bursts with weak low-frequency radiation Many high-frequency radio emitting streamers or streamer-like discharges that propagate in random directions can generate such radio bursts Lightning initiation may begin...
Yang1, Ting Shu1, Jiande Zhang1 & Huihuang Zhong1 The radio-frequency breakdown due to ultrahigh electric field strength essentially limits power handling capability of an individual high power microwave (HPM) generator, and this issue becomes more challenging for high frequency bands. ...
