The "5G" is pure marketing hype by Broadcom and it does no one any good when bloggers uncritically accept it as being a term with any agreed-upon meaning.
Broadcom claims that the new chip will improve "system power efficiency up to 25 percent when using wireless applications."
Samsung's Galaxy Note 3 includes an 11ac chip but it's a single stream implementation, notes MacRumors, Juli Clover.
Currently, Apple offers 11ac in its MacBook line of notebooks and some other products but not in the iPhone or the iPad. Both the latter in 2013 for the first time were equipped with 11n chips that supported the 5-GHz band, allowing both devices access to much cleaner and much less cluttered spectrum.
Users face a chicken-and-egg problem: even with 11ac in the iPhone, there are relatively few home, business, or public Wi-Fi networks what support 11ac today.
