How does 5G work?
5G networks can be built in different ways from multiple bands of wavelength spectrum: low-band, mid-band, and high-band.
High-band millimeter wave frequencies have greater bandwidth available to carry more data in dense urban areas but require cell sites to be in close proximity and have limited penetration in buildings. Mid-band balances speed and range, providing broader coverage than high-band. And it’s less impacted by buildings. However, much of its bandwidth is already in use, so there’s not a lot available for 5G growth. Low-band, like our powerful 600MHz spectrum, travels farther than other bands—over hundreds of square miles—and can pass through more obstacles, providing a better, more reliable signal both indoors and out.
