5G networks are upon us and this next-generation of wireless communication is being powered by a new technology known as millimeter wave (mmWave). U.S. carriers are particularly keen on the technology, and it will likely be used across the world to varying degrees. However, not every 5G network will necessarily use mmWave technology, at least not all of the time. As with every new technology, there are inevitable teething problems and hurdles to overcome before it goes mainstream. Millimeter wave technology has had its fair share of doubters in the past few years, with questions arising about its suitability over long distances, how well it can go through walls, and even if rain or a user’s hand might block the signal. These issues aren’t unfounded, but most of them have been worked out in recent years. MmWave technology is just about ready to make its public debut, so let’s examine the current state of these concerns. First, let’s quickly recap what millimeter wave is all about.
