"Maybe by 2020 the majority of consumers worldwide will have finally jumped on the 4G LTE-Advanced bandwagon, which launches later this year, just in time for the 5G network launch."
Revise this sentence please, it makes no sense whatsoever. First of all, the major carriers have no plans for LTE-Advanced yet. We're still worrying about LTE deployment and that's an expensive, lengthy process. To put a date on it is ridiculous. Secondly, LTE-Advanced will be marketed as 5G, even though according to the 3GPP it'll be true 4G (and the LTE you know now is 3G). Finally, how are people jumping on a bandwagon in 2020 for a 'later this year launch'. What are you even saying?
