da znam, cak kazu i 1 4g napram 600 5g, ali i dalje spaja je optikom. Iskreno nije moje podrucje, mozda kao ni tog novinara, ali gdje god sam citao o 5g, svi ju spajaju optikom.
As the figure "Current 4G vs. future 5G networks" shows, the range of a typical 4G macro cell today can theoretically cover 10 square miles. The plans for 5G have as many as 60 small cells covering just one square mile. Actual deployment needs would vary, but a 1:600 ratio is a whole new level of densification to consider.
Optical fiber is the preferred medium for existing wireless backhaul networks, and even in networks where this is not the case, the wireless backhaul eventually needs to connect into a fiber backhaul. Fiber will also be preferred for what is known as "fronthaul," connecting the dense mesh of 5G small cells. Why is this? Increased speeds with lower attenuation, immunity to electromagnetic interference, small size, and virtually unlimited bandwidth potential are among the many reasons why fiber is the right choice. The question becomes, "How many fibers are needed to support each cell?" And the answer will depend primarily on what technology protocols will be employed.
