Cool...just gonna let you know that lte-Evolution is actually true 4G, lte/lte-A was an amped up version of 3G, lte “evolution” 4G was actually supposed to come out 2 years ago...unfortunately the technology wasn’t ready?!
the tele companies market these techs with a different name, they had to adjust with the tech.
MIMO is a type of antenna which transmits frequencies , they have 2x2 (3G) 4x4(4G) 8x8,12x12(5G), to achieve true 4G the thought is to Have a clear path of transmission to push the 500 gbps...supposedly aluminum or stainless steel cannot provide this...
