LTE uses two different radio links for downlink and uplink, that is, from tower to device, and vice versa. For the downlink, LTE uses an OFDMA (orthogonal frequency division multiple access), which requires MIMO.
What you are referring to is called plaque, and it's a hallmark of atherosclerosis or arteriosclerosis (they both mean the same thing). Basically, cholesterol deposits end up lining the interior walls (lumen, intima) of the arteries narrowing the opening.
Blame It on the Bad Fat. The medical term for clogged arteries is atherosclerosis, and itâs a major risk factor for heart attack or stroke, because clogged and hardened arteries may restrict blood flow to some parts of the brain or heart. Sometimes the plaque buildup is hereditary, but often, itâs related to diet.lame It on the Bad Fat.
