Abstract
The main objective of this final Bachelor’s degree project is to design and study the relia-bility of a transoceanic shortwave radio link that connects London and New York. Two ofthe most important stock exchanges of the world are located in these two cities and theconnection between them is currently done through submarine optical fibers.In the last few years, with the automation of the stock market activity (a trend that is alsoknown as High Frequency Trading), several companies have begun to look for alternativesto optical fiber to reduce the latency of the link use this advantage to be more competi-tive. However, before designing the radio link, the behaviour of the ionosphere has beenstudied to correctly understand how ionospheric propagation works and what factors cancompromise the communication.The radio link design is based on the choice of different aspects such as the location of thestations, the type of antenna, the protocol or the propagation mode, among others. Thisselection has been made prioritizing the reliability of the link over other aspects such asthe capacity or the bandwidth.Once these aspects have been decided, the communication has been studied using anionospheric propagation prediction software called VOACAP. This software gives us veryrelevant information about the reliability or the power received. This will allow us to modelthis propagation by relating the behaviour of the different frequency bands with the varia-tions suffered by the ionosphere during the different months of the year and the differenthours of the day.On the other hand, this study demonstrates how the designed radio link substantially re-duces the latency of the fiber optic with a high reliability that can allow its use regularly.
