5G is Designed to be Ubiquitous
5G promises to bring far greater and more consistent coverage than LTE, thanks to a trend toward smaller land areas per transceiver, or cells, which is a result of the dense placement of smaller antenna elements.
One of the essential goals of 5G is to deliver a more consistent user experience. The 100 Mb/s minimum connection consumers can expect in dense urban areas is a major improvement over 2018’s United States speed of 16.31 Mb/s. In rural areas, that kind of ubiquity will rely on low-band spectrum, and in smart cities, high-band spectrum will achieve that consistency.
“High-frequency signals can be reused across short distances by different cells in a network, meaning the available spectrum is used more efficiently,” wrote Larry Greenemeier in Scientific American. “In addition, antenna size is inversely proportional to frequency size, so higher-frequency signals would require smaller antennas.”
Jumping from 4G to 5G
All of these ways that 5G is different from 4G are preparing the industry for new and ever-more-complex applications. The future is full of streaming 4K video, virtual reality (VR)/augmented reality (AR) experiences, and instant communications.
