5G signals are delivered on various platforms with VERY different results – Basically, 5G can be divided into three very different types:
Think of 5G as three different flashlights; the first flashlight has a broad beam but has limited strength and intensity (like a lantern). The second flashlight covers a smaller area (like a traditional flashlight) but is brighter and the third is more like a laser – very, very bright, but has a tiny coverage area…
The most popular 5G is a lower frequency (600-900MHz range) which is similar to 4G cell service. It covers an area similar to 4G, with very broad coverage, but has limited strength and bandwidth. This is what is being offered by cell carriers now.
Then there is mid-range 5G which covers a smaller area, but with more bandwidth and is stronger. It uses frequencies in the 30-250 MBPS, giving download speed higher than 4G cellular, but has coverage issues that make it impractical for the current cellular antenna network. This is well suited for fixed applications as opposed to mobile devices since it has a narrow coverage area.
Those big promises you hear about 5G are based on high band, or millimeter wave, using frequencies in the 24-54GHz range. This is more like a laser beam – very strong, has very high bandwidth, and covers a very small area. This high-frequency 5G is suited for very limited areas, often within a building that needs a local network (LAN) with a very high capacity in a small, well-defined space.
However, technology marches on! While 5G is being refined, 6G is on the way with frequencies in the sub-THz range – which is very, very high and very narrow (at least for now). The likely outcome is a network with multiple layers of frequencies for different purposes and types of users.
