I'm no spectrum expert but I can't grasp my head around how 5g is going to work on mmwave? I get that mmwave can carry large amounts of data but it's just so unstable. I mean these telecommunication companies will have to deploy ridiculous numbers of cell sites. Please help me understand. Lol. But I'm generally excited for the day we don't have to drive our own cars.
Such an amazingly broad question. Although propagation loss is high, antenna gain is also high, so it should in theory work. Problem is practical considerations in 20-30 GHz bands are just starting to be looked at now, and so it’s kind of a science project. On the plus side, early meAsurements show prop delay and fading is not as bad as worst case expectations.
Case closed this is the expert
While it's true that antenna gain is higher at such frequencies (because the smaller wavelength makes the antenna appear electrically larger), the OP is correct that connections are less stable when your frequency is in the tens of gigahertz. Here's why: 1. high antenna gain implies that the beam is highly focused, and can easily get deflected off its path by any obstruction. 2. waves in the tens of gigahertz don't penetrate through walls or obstacles as well as waves in the 100s of megahertz or in the low gigahertz.
Att already has 5g /s
Because the range for a radio is only a few hundred yards and not 4 miles, doesn’t matter as much. Also removes the FCC from the equation mostly (for spectrum licensing).
The FCC has forced this technological jump
We are deploying a ridiculous amount of small cell towers, so is Verizon. It will work, just only in cities. 5G in the ritual areas won’t be quite as capable.
Mesh network time?
Yeah I always saw it as WiFi++ not 4G++
