Sorry I wasn't around today to respond more timely, but I appreciate all the interest and thoughtful responses. After reading through them, I think I see a misunderstanding. One of the advantages of the pencil width beams is that they do not have to be on all the time. The beam will not turn on and point at you unless it sees your device advertising. As soon as that is interrupted, the beam goes elsewhere to service others within usually a few hundred microseconds. So the beam will not hit you, it is aiming at the antenna on your device, if the energy is not being absorbed into the antenna it goes away. So worse case you get a few 100us of lower level energy than the FR1 band. Think of it like this, say you are a gNodeB (5G BTS) your job is to shine a laser pointer on a sign that hays hello. As soon as you cant see it because someone got in front of it you look for a different sign to shine it on. You don't want to waste time and energy shining it on something that is not an antenna. So what happens when the FR2 mmwave is interreupted ? You of course fall back to FR1 which is on all the time. Remember it is the same frequencies as 4G LTE but now using 5G protocols and a new more efficient modulation scheme (5Gnr, for new radio which uses NOMA instead of OFDMA). So really you need both. It all depends on the amount of spectrum, but typically for most of the large carriers the low band users can expect 1Gbps - 2Gbps speeds and in high bands mmwave 2Gbps - 10Gbps. So even when it rains or you get blocked, it's still pretty darn cool !
